INTRODUCTION

 

THE NATURE OF METAPHYSICS

 

 

Origin of the Term “Metaphysics”

 

For a long time Aristotle scholars held that the term “metaphysics”[1] (from the Greek meaning literally “after the physics”) originated from a mere “shelving accident” by Andronicus of Rhodes (first half of the first century B.C.). It was commonly believed that Andronicus first gave the title “the books which follow the physics” in his re-ordered edition of the opera omnia of Aristotle (384-322 B.C.), where he placed the Stagirite’s fourteen books of first philosophy after those concerned with physics, simply because he was unable to properly name and classify them. However, in the middle half of the twentieth century this position came under fire with the publication of scholarly studies by Paul Moraux,[2] Hans Reiner,[3] and Anton-Herman Chroust.[4]  The last of these scholars, A. H. Chroust of the University of Notre Dame, maintains that the designation attributed by scholars to Andronicus of Rhodes “which owes its origin to a library cataloguing reference and, hence, to a mere accident born out of embarassment and practical necessity…this fanciful story…borders on the incredible.”[5]

 

Chroust mentions that both Nicholas of Damascus (flourished 2nd half of the first century B.C.) and the illustrious historian Plutarch (c. 45-c. 120 A.D.) utilized the term “metaphysics” to describe Aristotle’s fourteen books of first philosophy. Then, Chroust lists Alexander of Aphrodisias’ Commentary to Aristotle’s Metaphysics, written around 200 A.D., where we find Alexander explaining that the Stagirite himself described his books on first philosophy as “metaphysics,” for as regards our noetical process this subject matter comes after the physics (it belongs to a higher level of abstraction). It is true that first philosophy (metaphysics) by nature (in itself) comes before the physics (by reason of its sublimity), but with reference to our limited minds which start from what is accessible to the senses, physics comes before metaphysics.

 

Another source that Chroust gives us is the Commentary of Asclepius (6th century A.D.),[6] which is, to a great extent, reliant on Alexander. In his commentary, Asclepius says that Aristotle himself called his work “metaphysics,” for it systematically follows the books of the Physics.[7] Chroust goes on to maintain, along with Asclepius, that the term “metaphysics,” “to be sure, may have had its origin in the sequence of the Aristotelian works, but this sequence is by no means an external or accidental ‘order of shelving’ – an incident in the techniques used by librarians. It is rather a deliberate and necessary sequence that is decisively determined by the ‘order’ – the ‘prior’ or ‘posterior’ – of our noetic process. And this noetic process reverses the natural process or order. This fact, according to Asclepius, determines the didactic sequence which definitely calls for a Physics-Metaphysics sequence. Aristotle himself, Asclepius concludes, has planned this vital sequence. Hence the ‘order of shelving’ merely follows the ‘topical order.’[8] Chroust believes that the term “first philosophy”[9] that the Stagirite utilized to describe metaphysics expresses that which is first in the order of nature, while the term “metaphysics” proceeding in a reverse order, expresses that which is last “according to us,” that is, according to our cognitive processes.       

 

Chroust then proceeds to give us a fourth source: Themistius (4th century A.D.), in his Commentary on Aristotle’s Physics, also states that “as far as we are concerned, the Metaphysics comes after the Physics, but according to nature the order or sequence is reversed. That which is prior is prior in a dual sense. First in relation to us, and, secondly, in relation to nature. In relation to us that is prior which is better known to us and which we understand more readily…In relation to nature that is prior which according to its substance is the more simple (or uniform)…and, hence, the order is reversed here. Because in discursive reasoning we proceed from the composite to the simple or uniform which, according to nature, is the prior.”[10]

 

Chroust also mentions a fifth source: an anonymous scholion to the Metaphysics which reads that “the title metaphysics is derived not from the nature of the subject but rather from the order in which it should be read (or studied), because it [the Metaphysics] contains the first principles of physics.”[11]

 

The Role of J. G. Buhle. Where, then, did this “fanciful story” of a “shelving accident” involving Andronicus of Rhodes originate from? Apparently, from Johann Gottlieb Buhle, as Owens explains: “Toward the end of the eighteenth century, a German philologist and historian of philosophy, Johann Gottlieb Buhle (1763-1821), published at the early age of twenty-five a forty-two page discussion on the authenticity of the Aristotelian Metaphysics.[12] In the course of that examination Buhle eliminated from the unity of the Metaphysics, mostly on grounds of obvious failure to satisfy internal coherence, seven of its fourteen books. In his final paragraph (pp. 41-42), as though by way of afterthought, he asked how such alien documents found their way into the group of Aristotelian treatises on first philosophy, and replied that this became clear from the history of their transmission. Repeating the traditional account he went on without any change in style to narrate, as though part of the tradition, some further details that purported to round off the story: Andronicus of Rhodes, the first century B.C. editor of the Aristotelian treatises, arranged the Physics as the last in order according to his own systematic plan; but Andronicus still had a number of treatises left over that he did not know how to classify, and hence he appended them to the collection under the general title of ta meta ta physica, understood in the editorial sense of treatises placed after the physical ones!

 

“Buhle offered no evidence or reasons or arguments for this assertion. Actually, there were none to offer.[13] But his fantastic statement was taken up by encyclopedias and textbooks as it stood, and was universally accepted almost without question until the middle of the present century. Today it continues to be repeated, even though it is rejected unhesitatingly on historical grounds by scholars who have carefully considered the evidence.[14] It is an explanation that would render the term ‘metaphysics’ as doctrinally meaningless as the heading ‘appendices’ over a nondescript group of documents unable to be absorbed into the regular sequence of a book.”[15]

 

Names Given to Designate Our Subject Matter

 

Metaphysics. Meaning “after the physics,” the term metaphysics, as was already mentioned, had been traditionally attributed to Andronicus of Rhodes due to “a shelving accident,” by him, but a number of twentieth century scholars have attributed the term to early Peripatetics utilizing the term to describe Aristotle’s fourteen books of first philosophy. The term was meant to have a didactic significance, namely, that, according to our limited mode of cognition, metaphysics (which has as subject being in general, gotten through the negative judgment of separation) comes after the physics (which is easier to grasp by the mind of man), but in itself metaphysics is prior in importance to physics. The later Peripatetics continued this tradition of naming our subject matter “metaphysics” and with the passing of time the term became widely used, especially by medieval scholastic philosophers, for, hovering above physics and the other particular sciences with its third degree of abstraction (properly called separation), it is able to go beyond the sphere of the corporeal world studied by physics into the realm of the immaterial.[16] 

 

First Philosophy. Aristotle called our subject matter “first philosophy” since it considers the first principles and first causes of all things and also because it gives these first principles (e.g., non-contradiction, causality, finality) to the other sciences, which presuppose them.[17] “As directive knowledge metaphysics is called first philosophy. The name does not refer to the chronological order of learning but to the priority that metaphysics enjoys with respect to other human sciences. Metaphysics has priority over other sciences because it, as the science of indemonstrable principles of being, is the guardian of the first principles of other sciences. In addition, metaphysics, as natural theology, is able to direct other sciences toward God, who is the origin and end of all things.”[18]   

 

Metaphysics is “first philosophy” since it is the highest and most important part of theoretical or speculative philosophy, as well as being the highest part of the theoretical sciences (were are here speaking of metaphysics in the general sense which includes its three parts, namely, general metaphysics, gnoseology, and philosophy of God). The weakness, however, with this designation is that it does not give us the object of the science of being.

 

Divine Science. Aristotle also called the science of metaphysics the “divine science.” Though metaphysics is rightly deemed a divine science since it delves into the first principles and ultimate causes of things, explaining principles that are utilized in the demonstration of the existence of God and in the explaination of His nature and attributes, God, however, is not the proper object of general metaphysics but rather its final term as the affirmation of the existence of God is the principal conclusion which the science of metaphysics establishes. Natural theology or philosophy of God is more properly called “divine science” than metaphysics, but, strictly speaking, the “divine science” is sacred theology.

 

Wisdom. The Stagirite also called metaphysics “wisdom” (sophia). Metaphysics truly is wisdom, a knowledge of the ultimate causes and first principles of all reality: “The special sciences deal with the particular causes of kinds of being. Metaphysics, however, deals with being precisely as being in its most universal causes and principles. This kind of science is called wisdom. St. Thomas observes: ‘Wisdom is a certain kind of science insofar as it has this in common with all the sciences, namely, that it demonstrates conclusions from principles. But since over and above the other it has this property that it judges all others, not only as to conclusion but also as to first principles, it is therefore a more perfect virtue than science.’[19] Wisdom (sapientia) is the knowledge of things in the light of their highest causes. It is more perfect than a special science (scientia) which considers secondary principles, as biology treats the principles of living things, because wisdom is concerned with the highest principles of all things. It is more perfect than understanding (intellectus) because understanding gives us the knowledge of the immediate truth of self evident principles, as the principle of non-contradiction, but metaphysics gives us a deeper knowledge of the first principles, judges their truth and defends their validity.[20][21]

 

Ontology. During the seventeenth century the term “ontology,” as a substitute for metaphysics, began to make its appearance in the works of the Marburg logician Rudolph Goclenius (1547-1628)[22] and the German Cartesian philosopher Johannes Clauberg (1622-1665),[23] but it was popularized by the philosopher Christian Wolff (1679-1754), a rationalist, who profoundly influenced the pre-critical period of the transcendental idealist Immanuel Kant (1724-1804). “Ontology,” a term derived from the Greek present participle ontos of the verb “to be” einai and the noun logos signifying “science,” means the “science of being.” Though rationalist philosophers have a history of preferring the term “ontology” over “metaphysics,” both are valid terms and can be used interchangeably to describe our philosophical science in question.       

 

Metaphysics Defined

 

Metaphysics is the philosophical science that studies the ultimate causes and first principles of all things (or all reality). It studies the ultimate causes of things (the four causes, namely material causality, formal causality, efficient or agent causality and final causality, as well as the First Cause of all things, namely, God). Thus, metaphysics is different from the particular sciences (like biology, chemistry, physics) which study the proximate causes of things, which produce in an immediate manner certain specific effects (i.e., the heart is the organ that causes blood circulation). Metaphysics also studies first principles, like the principle of non-contradiction (wherein we find that being is not self-contradictory), causality (in all its various formulations like “that which is moved is moved by another,” “that something which begins to be has a cause,” “everything contingent requires a cause,” and “if something possesses a perfection not derived from its essence, that perfection must come from an external cause”), as well as the constitutive principles of being, like act and potency, substance and accidents, and essence and act of being.     

 

Metaphysics is defined as the science of being as being.[24] Science here is not understood in the reductionistic and positivistic sense as referring solely to the experimental particular sciences, like biology and chemistry, but in the classical sense of “certain knowledge through causes.” What is metaphysics’ material object and formal object? Its material object (that is, its subject matter) is being. Its formal object (or the particular point of view or aspect in which the subject matter is studied) is being as being (ens inquantum est ens). Now, sciences are defined and differentiated from one another by reason of their formal object, and metaphysics is thus defined as “the science of being as being.”[25] Concerning metaphysics as that science which treats of being qua being, St. Thomas Aquinas writes, in his Commentary on Aristotle’s Metaphysics, the following: “Because a science ought to investigate not only its proper subject but also the latter’s essential attributes,[26] Aristotle says that there exists a science which takes as its subject being precisely as such, and ‘those things which belong to being in virtue of its own nature,’ namely, being’s essential attributes. Aristotle here uses the expression ‘being in so far as it is being’ because the other sciences, which treat of particular beings, do indeed consider being, for all the subjects of sciences are beings, yet they do not consider being as being, but as this sort of being; for example, number, line, fire, or something of the kind. Aristotle employs the phrase ‘and those things belonging to being in virtue of its own nature,’ not simply ‘those things which appertain to or exist in being,’ in order to point out that it is not the office of a science to consider those things that exist in its subject accidentally but only those that are present in it essentially. Thus, geometry is not concerned with the question whether a triangle is made of copper or of wood, but only with its absolute nature, according to which it has three equal angles.[27] It does not, therefore, appertain to the science whose subject is being to consider all that exists in it accidentally, since it would then be taking into account accidents which are investigated in all sciences. For although all accidents exist in some being, not all accidents exist in a being inasmuch as it is being. Thus essential accidents of an inferior or a subordinate thing are accidental accidents in relation to the superior; for example, accidents essential to man are not essential to animal.[28]

 

“The necessity of this science of metaphysics, which contemplates being and its essential attributes, is manifest; such things ought not to remain unknown because it is upon them that knowledge of other things depends, for on the knowledge of common or universal things hinges the knowledge of proper or individual things. That this science is not a particular science, Aristotle shows by the following argument. No particular science considers universal being as such, but only some part of being cut off from its other parts, and of this separated part it examines the essential attribute. The mathematical sciences, for instance, investigate a particular kind of being, namely, the quantitative,[29] whereas the common science, metaphysics, considers universal being as being. Therefore it is not to be identified with any particular science. No particular science treats of being as being, that is, being-in-common, nor does any particular science treat of any particular being, simply as being. For instance, arithmetic does not consider number as being, but as number. It is the office of the metaphysician, however, to consider any and every being, precisely as being.[30] And because it pertains to the same science to consider being as being, ‘and, concerning being, what it is,’ namely, its essence (for every thing has actual existence through its essence), so it is that the particular sciences…are not concerned with the problem of determining what being is – its quiddity or essence and its definition, which signifies the essence. Rather, from the essence such sciences proceed to other matters, using the presupposed essence, as if it were an already demonstrated principle, in order to prove other things. Just as no particular science determines the essence of its subject, so none of them says regarding its subject, that it is or is not. And understandably so; for it belongs to one and the same science to settle the problem of existence and to discover the essence…It is proper to the philosopher, to him who studies being as being, to consider both problems. But every particular science presupposes concerning its own subject both that it is and what it is, as Aristotle states in the first book of the Posterior Analytics. And this shows that no particular science treats of being as such, nor of any being precisely as being.”[31] 

 

Describing the material object and formal object of metaphysics and relating this to wisdom (sophia), Wallace writes: “In its material object, or the number of things it studies, metaphysics is all-inclusive, extending to everything and every aspect of whatever is or can exist, whether of a sensible, material, physical nature or of a higher, non-material nature. Its formal object is being precisely as being (ens qua ens), i.e., according to the relation that any thing or aspect of things has to existence, rather to one of the particular aspects treated in the other branches of philosophy. The unity of this point of view, centered on what is most fundamental to all reality, enables metaphysics to investigate the way in which the many are interrelated to the one in the deepest ontological sense. Further, since things are reflected in knowledge, it enables metaphysics to order and evaluate the various types of speculative and practical knowledge, on which account it is also called wisdom.”[32]

 

To sum up, the material object of metaphysics is being (all being), that is, all reality. The formal object of metaphysics is, from the nature of the abstraction which this science demands (which is separation), being as being (ens in quantum ens).[33] Metaphysics does not restrict itself to some particular aspect of being but rather treats of what is common to all beings, such as its constitutive principles or components, its properties and attributes, its divisions and its causes. 

 

The Method of Metaphysics

 

The method of a science is the way in which it renders its object intelligible. Metaphysics utilizes both induction and deduction[34], not deduction exclusively nor induction exclusively, though induction is used principally.[35]  

 
The Contents of Metaphysics

 

Metaphysics (we are speaking here of general metaphysics) has a three-part structure: it studies the metaphysical structure of being (act and potency, matter and form, substance and accidents, essence and act of being), its properties (or the transcendentals of being, namely thing, something, one, truth, good, and beauty), and causality (material, formal, efficient, and final causality).      

 

Metaphysics Operates at the Third Degree of Abstraction (Properly Called Separation)

 

The level of abstraction that metaphysics operates at is not the first level (which concerns the physical sciences), nor at the second level (which concerns mathematics), but at the third level (properly called separation).[36] The three levels of abstraction are described as “degrees of abstraction” in the sense of a progressive elevation above matter. St. Thomas writes about the three levels in his Commentary on the Physics of Aristotle, stating: “There are some things whose being depends on matter, and which cannot even be defined without matter. Other things, while not being able to exist except in sensible matter, do not include sensible matter in their definition… Lastly, there are things which do not depend on matter, whether in their being or in our manner of understanding them – either because they are never found in matter (like God and the other spiritual substances) or because they are not found in matter always (like substance, act and potency, and being itself). These realities constitute the subject matter of metaphysics. Mathematics deals with those realities that depend on matter as to their being but not as regards our manner of understanding them. Physics deals with realities that depend on matter both as regards their being and as regards our manner of understanding them.”[37]

 

The First Degree of Abstraction. As regards the first degree of abstraction (pertaining to the physical sciences) the intellect abstracts from matter so far as it is the principle of individuation, therefore, from individual matter (also called signate matter or materia signata). However, matter is still retained in so far as it is the basis of sensible qualities. It thus retains sensible or common matter (materia sensibilis vel communis). Regarding the first level of scientific knowledge which employs the first degree of abstraction, Koren writes: “On the first level, scientific knowledge ‘terminates in the senses,’ for ‘the properties and accidents of the thing which are shown by the senses sufficiently express the nature of the thing. In this case, the judgment of the intellect concerning the truth of the thing must be conformed to that which the senses reveal about the thing.’[38] The science which is concerned with this level of knowledge is called physical or ‘natural science, i.e., we judge of natural things according as they are revealed by sense experience…and whoever disregards sense experience with respect to the realm of nature falls into error.’[39] Hence the conclusions of physical sciences must always be open to verification by sense experience. From this it follows that physical sciences must retain something which is subject to sense experience; for otherwise no verification by means of the senses would be possible.

 

“It is clear, therefore, that scientific knowledge on this level may make abstraction only from so-called ‘individual matter,’ i.e., from the differences which distinguish this man from that man, this sample of sodium from that sample of sodium, etc.[40] But it must retain the common ‘sensible matter’ which enters into the definition of the things it considers. By sensible matter is meant matter ‘insofar as it is subject to sensible qualities, such as being hot or cold, hard or soft, and such like.’[41] Common sensible matter refers to those sensible qualities which are found in individuals insofar as they belong to a certain group or class. That common sensible matter is retained in physical science should be clear. For questions referring to such matter are meaningful in physical science. For instance, it makes sense to ask questions about the temperature, hardness, density, etc. of a physical object.

 

“Knowledge on this level is said to be on the first degree of abstraction. The intellect considers such things as water in general, man in general, plants in general, or a certain type of water, man or plant, etc., without being particularly interested in the individual as such. The object is always something which can neither exist nor be understood without sensible matter.[42] Experimental sciences, such as physics, chemistry, biology, experimental psychology, etc., belong to this level of scientific knowledge.[43] 

 

The Second Degree of Abstraction. The second degree of abstraction proper to mathematics abstracts from common sensible matter, but keeps under consideration the material substance as quantified, which is called intelligible matter (materia intelligibilis).[44] “Intelligible” in this context refers not so much to the intellect as to the imagination, so much so that one could speak here of “imaginable matter,” which is matter as terminating in and known by the imagination, an internal sense faculty, in contrast to matter as terminating in and known by the external sense.[45] Koren writes: “On the second level, scientific knowledge ‘terminates in the imagination,’ for ‘when abstraction is made from the sensible conditions of a thing, there still remains something imaginable; so that with respect to such objects judgment must be made according to what the imagination shows.’[46] This ‘something imaginable’ is quantity, i.e., extension and number, which are abstracted from all sensible qualities. A simple consideration will make this clear. If a man inquires about the temperature of a triangle or the softness of number ten, the listener will conclude, no doubt, that the fellow must have escaped from an asylum, because such questions do not make sense. The reason why they are meaningless is precisely that quantity abstracts from all sensible qualities. The study of mathematics belongs to this level of scientific knowledge. ‘In mathematics the judgment of knowledge must be terminated in the imagination and not in sense experience because a mathematical judgment exceeds the apprehension of the senses.’[47] The lines, figures, numbers, etc. considered in mathematics are not objects of sense experience but exist only in our imagination, although it is true that sense-perceptible representations of them on paper or a blackboard may be used to aid our imagination. Hence verification by sense experience is not possible with respect to mathematical objects.

 

“Scientific knowledge on this level is said to be on the second degree of abstraction from matter. It abstracts not only from individual matter, but also from common sensible matter, and retains only quantity, which ‘can be understood in a substance before there is understanding of the sensible qualities by which matter is called sensible; hence according to its proper nature, quantity does not depend upon sensible matter, but only upon intelligible matter.’[48] By ‘intelligibile matter’ is meant ‘substance insofar as it is subject to quantity.’[49] Intelligible matter has to be retained because numbers, dimensions and figures ‘cannot be considered unless the substance which is their subject is considered.’[50] The object of scientific knowledge on this level ‘depends upon (sensible) matter for its existence, but can be understood without it because sensible matter does not enter into its definition.’[51] All mathematical sciences belong to this level of scientific knowledge.[52][53]

 

The Third Degree of Abstraction (Properly Called Separation). Separation is the proper level of abstraction in which metaphysics operates wherein metaphysical concepts correspond to certain aspects of things understood without sensible matter, and which are also encountered in beings without matter. Such metaphysical notions (i.e., act, potency, substance, accidents, essence, act of being) are intelligible aspects of beings that sometimes are in matter (for example, a rock is composed of act and potency, substance and accidents, and essence and act of being), but which can also exist separated from physical matter (for example, an angel, also called the separated substance, which is wholely without matter, has a composition of act and potency, substance and accidents, and essence and act of being). Even if material beings exist, being does not necessarily entail being in matter. Koren explains that “On the third level, scientific knowledge ‘terminates in the intellect,’ for ‘there are things which transcend both that which falls under the senses and that which falls under the imagination’[54]; not that we obtain knowledge of these things independently from sense experience and imagination, but rather that ‘the judgment of knowledge must not be terminated in either imagination or sensation.’[55] On this level, knowledge abstracts not only from all individual matter, as in experimental sciences, and from common sensible matter, as in mathematics, but from all matter. Thus we reach the highest or third degree of abstraction from matter. Scientific knowledge on this level considers ‘either things which never exist in matter, such as God and angels, or things which in some cases exist in matter but not in others, such as substance, quality, potency and act, the one and the many, and things of this sort,’[56] or in general ‘separate (i.e., immaterial) substances, and whatever is common to all beings’[57] and therefore most universal. In other words, the object of scientific knowledge here is ‘wholly independent from matter, both as to its existence and as to its understanding.[58] Science on this level is called metaphysics.”[59]

 

Even though metaphysics operates at the highest degree of abstraction, this does not mean that it is a science that has nothing to do with reality (as it would deal only with abstractions, the metaphysician being lost in the ivory tower of his immanent consciousness). In fact, metaphysics deals pre-eminently with the real, and the metaphysician is, above all, a realist: “The word ‘separation’ must not,” says H. D. Gardeil, “lead us astray in another direction. When, in other words, metaphysics is said to be the science of the ‘separate’ or, if one prefers, of the ‘abstract,’ this does not imply that its object is divorced from real existence but only from the material conditions of existence. It could not be otherwise. Indeed, we shall see that the object of metaphysics is eminently real and concrete; so that far from being out of touch with reality, the metaphysician is in the full sense of the word more a realist than any of his fellows in the fraternity of scholars and scientists. And this is true whether he considers, under the aspect of being, the totality of things material and immaterial or whether, sectoring his horizon, he fixes attention on what is real above all because immaterial above all: pure spirits, that is, and infinitely above them, God.”[60]

 

Separation is an operation performed, not by the first operation of the mind (simple apprehension), but by the second operation of the mind, that is, judgment; it is a negative judgment wherein we discover being as being, the subject of metaphysics. John Wippel explains that, for Aquinas, “separation is the process through which one explicitly acknowledges and asserts that that by reason of which something is recognized as being need not be identified with that by reason of which it is recognized as enjoying a given kind of being, for instance, material being, or changing being, or living being. It may be described as a negative judgment in that through it one denies that that by which something is recognized as being is to be identified with that by reason of which it is a given kind of being. It may be described as separation because through this judgment one distinguishes two intelligibilities, and denies that one is to be identified with or reduced to the other. One distinguishes the intelligibility involved in one’s understanding of being from all lesser and more restricted intelligibilities. Thus one negates or eliminates restriction of being to any given kind from one’s understanding of being. One judges that being, in order to be realized as such, need not be material, or changing, or quantified, or living, or for that matter, spiritual. Hence one establishes the negatively or neutrally immaterial character of being, and prepares to focus on being as such or as being rather than on being as restricted to this or that given kind.

 

“Through separation one does not deny that beings of this or that kind also fall under being. On the contrary, by denying that being itself must be limited to any one of its actual or possible kinds, one opens the way for considering these, including the differences which are realized in each, within the realm of being, and as being. Even purely material beings can be studied not only insofar as they are material and changing as in physics, but simply insofar as they share in being. This kind of study, of course, will not take place in physics, but in metaphysics, the science of being as being.”[61]      

 

The Difficulty of Metaphysics

 

Precisely because it operates at the third level of abstraction, metaphysics is the most difficult to learn of all of the human sciences, that is, of all the sciences discoverable by the light of human reason alone. For this reason, one should undertake this noble science only after having studied, for example, logic, cosmology, and the philosophy of animate nature. Metaphysics is usually grasped when one has reached a certain level of dominion over the passions (which cloud the understanding), developed a good habit of intellectual contemplation, and attained a sufficient level of intellectual maturity. Consequently, most young people who study metaphysics in their youth have only a superficial knowledge of the principles of the science of being as being. Aquinas explains that “As far as wisdom is concerned, he (Aristotle) adds that young persons do not believe – that is, do not understand with their mind – the objects of wisdom or metaphysics, although they may speak them with their lips. But regarding mathematical entities, their essences are not hidden from them, because the definitions in mathematics concern things that are imaginable, whereas objects of metaphysics are purely intellectual. Now young people can easily grasp what falls under the imagination. But they cannot understand with their minds what transcends sense and imagination, because their intellects are not trained to such consideration owing to the shortness of their life and the many changes of their nature. Consequently, the fitting order of learning will be the following: first, boys should be instructed in logic, because logic teaches the method of the whole of philosophy. Second, they should be instructed in mathematics, which does not require experience and does not transcend the imagination. Third, they should learn the natural sciences, which although not transcending sense and imagination, nevertheless require experience. Fourth, they should be instructed in the moral sciences, which require experience and a soul free from passions. Fifth, they should learn metaphysics and divine science, which transcend the imagination and demand a robust intellect.”[62]

 

Metaphysics as Wisdom

 

Metaphysics is wisdom, theoretical or speculative wisdom. In his Metaphysics, Aristotle explains that the truest characteristic of wisdom is that it is the science of ultimate causes and first principles. Metaphysics, which the Stagirite calls “First Philosophy,” studies the ultimate causes and first principles. Therefore, metaphysics is wisdom, a purely human wisdom, wisdom gotten by the light of natural reason alone. 

 

Is there a theoretical wisdom superior to metaphysics? Yes. Sacred Theology, the theoretical wisdom par excellence. In the Summa Theologiae, the Angelic Doctor writes that sacred theology is “wisdom above all human wisdom; not merely in any one order, but absolutely. For since it is the part of a wise man to arrange and to judge, and since lesser matters should be judged in the light of some higher principle, he is said to be wise in any one order who considers the highest principle in that order: thus in the order of building he who plans the form of the house is called wise and architect, in opposition to the inferior laborers who trim the wood and make ready the stones: As a wise architect I have laid the foundation.[63] Again, in the order of all human life, the prudent man is called wise, inasmuch as he directs his acts to a fitting end: Wisdom is prudence to a man.[64] Therefore he who considers absolutely the highest cause of the whole universe, namely God, is most of all called wise. Hence wisdom is said to be the knowledge of divine things, as Augustine says.[65] But sacred doctrine essentially treats of God viewed as the highest cause – not only so far as He can be known through creatures just as philosophers knew Him – That which is known of God is manifest in them[66] – but also so far as He is known to Himself alone and revealed to others. Hence sacred doctrine is especially called wisdom.”[67] 

 

Is there a wisdom higher in the hierarchy of wisdoms than these two theoretical wisdoms, namely, metaphysics and Sacred Theology? Yes. Infused wisdom (gift of the Holy Spirit): “By infused wisdom the soul judges in the light of connatural knowledge, connatural by grace with God’s knowledge; its foundation is the love that is charity (in the gospel sense), and its object is God as He is in Himself but attained through a suprahuman mode of acting, or rather of being acted on.”[68] Maritain explains that “theology is theoretical wisdom, par excellence the wisdom which knows God by the intellect and its ideas, that is to say, by the normal processes of human knowledge. There is another wisdom of a still higher order which is a gift of the Holy Spirit, and enables us to know God experimentally and by means of charity. It enables us to judge of divine things instinctively, as the virtuous man judges of virtue (per modum inclinationis), not scientifically as the moralist judges of virtue (per modum cognitionis).”[69] Finally, is there a highest wisdom, a wisdom above all other wisdoms? Yes. God who is Wisdom Himself. 

 

It belongs to the office of the lover of wisdom to know how to direct and order things to their proper ends; aside from functioning as a negative rule with respect to the particular or secondary sciences, rejecting as erroneous any theory that contradicts its own principles (for example, a scientific theory that maintains that only matter exists will be judged to be false by the metaphysician), metaphysics has a regulative or directive function in relation to these sciences. It governs the other sciences; the particular or secondary sciences are indirectly subordinated to ontology or metaphysics. “Since the laws of one science are subordinate to the laws of a superior science, it clearly follows that it is the office of the superior science to govern the inferior. But since the principles of philosophy (the first philosophy or metaphysics) are the absolutely first principles of all human knowledge, they possess an authority over the principles of all other human sciences, which are in a certain sense dependent upon them. That is to say, philosophy (the first philosophy or metaphysics) governs the other sciences.

 

“Since the principles of philosophy (the first philosophy or metaphysics) are the absolutely first principles of all human knowledge, the principles or postulates of all human sciences are in a certain sense dependent upon them. They do not, it is true, depend directly on the principles of metaphysics, as the truth of a conclusion depends on the truth of its premises. They are self-evident by the light of natural reason (principia per se nota). But they are not absolutely speaking (simpliciter) first principles. Therefore, although they carry conviction independently of metaphysics, nevertheless they presuppose in fact the principles of metaphysics and can be resolved into them. They can be known without an explicit knowledge of the principles of metaphysics, but they could not be true, unless the latter were true. And in this sense they are indirectly subordinate to the latter. For instance, the mathematical axiom, two quantities which are equal to a third quantity are equal to one another, can be resolved into the metaphysical axiom of which it is a special case: two beings identical with a third are identical with one another. It is for this reason that all the sciences are said to be indirectly subordinate to metaphysics. Moreover, they are obliged on occasion to employ the universally valid principles of metaphysics. In this sense they are said to be subordinate to metaphysics in a particular aspect or relatively (secundum quid).”[70]

 

Aside from being able to order things to their ends, the lover of wisdom also has a number of other characteristics, namely: “(1) he is one who knows all things at least in broad outline, though he may not know all things in the individual detail; (2) he is one who understands difficult things over and beyond the ordinary understanding of men; (3) he is one who has greater certitude than most men possess; (4) he is one who better understands the causes of things; (5) he is one who is more educated in the liberal arts, because he prizes knowledge as a goal in itself rather than as an instrument for something else; (6) he is one who has greater dignity because he is able to direct others. These are the characteristics that belong to the metaphysician and to the science of metaphysics.”[71]

 

A Short History of Metaphysics

 

While the pre-Socratic philosophers (Thales, Anaximander, Anaximenes, Heraclitus) are more properly called cosmologists (or philosophers of nature) rather than metaphysicians, Parmenides (c. 540-470 B.C.) is said to be the first metaphysician, since he placed being on center stage. After Parmenides being lost its preeminence in philosophy, mainly because of the anthropocentric, anti-metaphysical relativism of the Sophists. Socrates (470-399 B.C.) combatted the Sophists and sophistry, affirming the existence of absolute truths and moral values, but he was more interested in ethics or moral philosophy than in theoretical metaphysical speculation. Being was to regain its preeminence with the thought of Plato (427-347 B.C.), but Plato erred in his doctrine of Forms, believing that the universal really existed in reality as universal (he was an exaggerated realist or so-called ultra-realist, a position which tends to identify logic and the mathematical method with metaphysics). Hence, though metaphysics recovered its ground as the queen of the human sciences, Platonism was a defective metaphysical system. Plato’s errors were to be corrected by the moderate realism of Aristotle (384-322 B.C.), who was the first systematizer of the science of metaphysics. It was he who defined metaphysics as the science of being as being and described in great detail the principles of first philosophy. The fourteen books of the Metaphysics is his master work on the subject of metaphysics, a work which was to be commented upon by later generations of philosophers like Avicenna, Averroes, and Aquinas. St. Thomas Aquinas (1225-1274) adopted much of the metaphysical thought of Aristotle but he went further and perfected it with his doctrine of transcendental metaphysical participation and his elucidations on the central role of esse in metaphysics, the act of being as act of acts and perfection of perfections; whereas Aristotle stressed the primacy of the form, Aquinas stressed the ultimate metaphysical foundation of all things in the act of being (esse). With the nominalism of William of Ockham (c. 1290-1349), and his negation of abstraction, the science of metaphysics begins its gradual decline towards skepticism. An attempt to resurrect the science was made by the Jesuit Francisco Suarez (1548-1617), whose work, the Metaphysical Disputations, had a great influence in universities and seminaries throughout Europe. Nevertheless, Suarezian metaphysics is, in a certain sense, a return to the essentialism of the ancients. He also committed the error of denying the real distinction between essence and act of being, a central doctrine of authentic realist metaphysics, which would contribute to the growth of rationalist, and even pantheist, metaphysical systems after his death.

 

With the advent of Rene Descartes (1596-1650), metaphysics begins its steep decline; Cartesian rationalist philosophy basically substitutes metaphysics for its own deductive mathematical method, that is, the mathematical method basically becomes first philosophy. This corruption of metaphysics, which should be realist and operate at the third degree of abstraction, has its roots in immanentism, which makes thought prior to being. It maintains that what is known in the first instance can only be that which is within human consciousness (i.e., ideas, sensations), which is different from realism, which holds that the object which is known in the first instance is the transsubjective thing in reality. Once the cogito starting point of Cartesian rationalism is accepted and immanentism upheld, gnoseological, and then ontological, transcendence is eliminated, and what one ends up with is merely a thought-of reality. In short, immanentism traps one within the subjective prison of the mind. The history of modern philosophy from Cartesian rationalism onwards is a sad testament to this voluntary imprisonment.

 

Immanentism is really the great adversary of metaphysics, as is manifested, for example, in the immanentist systems of Humean phenomenalism and Kantian transcendental idealism, both of which asserting a noumenal agnosticism. At the end of his Enquiry Concerning Human Understanding, the radical empiricist David Hume (1711-1776) dismisses metaphysics altogether as sophistry and illusion, the unhappy result of his reduction of knowledge to mere sense knowledge, eliminating the intellectual, abstractive knowing essential to the science of ens qua ens. The transcendental idealism of Immanuel Kant (1724-1804) “was intended as an attempt to pass beyond empiricism and ‘dogmatic’ rationalism by the critical method, which was meant to reveal the conditions of possibility of an authentic scientific knowledge. This ended, however, in a theory of knowledge which tried to go beyond empiricism by a subjective idealism and rejected the possibility of metaphysics as science. To use understanding metempirically, that is, to exercise intelligence beyond the field of phenomenological data, in that of pure ideas, offered no guarantee against “transcendental illusion.” Kant, then professed a metaphysical agnosticism…”[72]

 

Nineteenth century pantheistic (and crypto-atheistic) absolute idealism (Fiche, Schelling, Hegel) discarded the thing-in-itself and made mind the positer and creator of its own object. There is an identification of metaphysics and logic, notoriously represented in the panlogicism of Hegel. In the monistic idealism of Johann Gottlieb Fichte (1762-1814), “the abolute Self or absolute Subject becomes conscious of itself in setting up the Non-Self, to which it is opposed as to its proper limitation, and beyond which it unceasingly tends to go in virtue of its own essential dynamism. The Non-Self has no subsistence in its own right. It is in and for the Self, with nothing to do save provide the Self with an obstacle to overcome.”[73] The aesthetic absolute idealism of Friedrich Wilhelm Schelling (1775-1854) “sought out to complete and correct the work of Fichte, but modified his own system more than once, leaving it incomplete. From the earliest phase of his thought he emphasized the Non-Self and professed an objective idealism, which he contrasted with the subjective idealism of Fichte. Later he put at the origin of all things an Absolute from which Nature and Spirit, the world of matter and that of consciousness, emanate in parallel.”[74] For the most famous and influential of all the absolute idealists, namely, Georg Wilhelm Friedrich Hegel (1770-1831), “being and thought are identical and the law of reality is the law of the mind (panlogism). The law which orders the evolution of mind is the dialectic of thesis, antithesis, synthesis. The measure in which thought advances is thus the measure in which reality develops. Pure Idea comes to be in two parallel orders, that of Nature (Idea alienated in unconsciousness) and that of Mind (Idea integrated into consciousness). In Mind, or Spirit, itself, subjective Spirit (freedom in essence) and objective Spirit (freedom expressed in law, morality, etc.) can be distinguished. The synthesis of subjective and objective Spirit is absolute spirit, expressed in art, religion and philosophy.”[75] 

 

Nineteenth century Positivism dismissed metaphysics as illusory and detrimental to the advancement of the positive sciences (e.g., Comte’s three stages), while twentieth century Neo-Positivism or logical positivism, with its principle of verification (which maintains that all meaningful propositions should be verifiable, either directly or indirectly, by sense experience), likewise dismisses all metaphysical enunciations as meaningless. Logical positivism castigates metaphysics as “nonsense because its sentences ‘fail to conform to the conditions under which alone a sentence can be literally significant,’[76] namely, sensible verification. Its statements belonged to the category neither of the true nor of the false, but of the meaningless. Linguistic analysis distinguished it sharply from science, regarding it either as a diseased intellectual condition to be cured by the therapy of the linguistic analyst, or as a group of problems that inevitably arise from the use of natural language and that are to be solved by linguistic elucidation.”[77] The logical positivists dismissed metaphysics as “an emotional outpouring that should use poetry as its medium, but instead used didactic language in an affort to represent itself as objective truth.”[78]

 

The problem, of course, with the Neo-positivist or logical positivist principle of verification is that the principle itself is unverifiable in sense experience, it being a metaphysical principle grasped not by the senses but is given in intellectual knowledge, something which the philosophers inspired by empiricist phenomenalism deny, since, for them, knowing is reduced to sense knowing. If immanentist phenomenalism reigns, metaphysics as a science is destroyed, for being qua being, substance as substance, and the principle of causality, are all grasped by the intellect and not understood by the senses. Thus, there is an urgent a need for a return to a methodical philosophical realism that makes being prior to thought, is respectful of both gnoseological and ontological transcendence, and does not subordinate metaphysics to any one of the merely particular human sciences discoverable by the lumen of reason alone.


 

 

PART ONE: THE METAPHYSICAL STRUCTURE OF BEING

 

 

CHAPTER 1

 

BEING

 

 

Being (Ens)      

 

Being (ens) is that which is. It is that which has the act of being (esse). The notion of being (ens) implies a composition of a subject (that “something” which is and is the real subject to which the act of being belongs), and an act (the very act of being of that “something”).[79] Every finite being (ens) has a real distinction between essence (essentia) and act of being (esse).[80] With God, the Infinite Being, on the other hand, essentia and esse are identified. God’s Essence is To Be. Essence is that which makes a thing to be what it is, while act of being (esse) is that which makes a thing to be. We will take up a more detailed study of these two metaphysical principles of being, essence and act of being, later on in separate chapters.    

 

Quasi, Not Strict, Definition of Being

 

Being cannot be strictly defined. The reason for this is that a strict definition consists of the genus of a thing and a specific difference which is not actually contained in the genus. The strict definition of man, for example, would be “rational animal” (this is his metaphysical essence, in contrast to his physical essence which is “hylemorphic composite of body and soul”) “Rational” would be his specific difference and “animal” would be his genus. Being, however, is not contained in a genus for whatever would be named as a genus would fall under “being” and thus could not possibly be its genus. Bittle explains that “‘being’ admits of no strict philosophic definition. Such a definition would demand a proximate genus and a specific difference. The proximate ‘genus’ includes within its comprehension all the essential elements of the genera above it and therefore includes all the beings that are cognate or similar in nature to the thing which is to be defined. The ‘specific difference,’ on the other hand, brings in the distinctive element which separates this thing from all others of a similar nature, by showing in what manner it is different from all others with which it might be erroneously identified.

 

“Take as example ‘man.’ Man is defined as a ‘rational animal’; ‘animal’ is his proximate genus, ‘rational’ is his specific difference. The proximate genus ‘animal’ includes within its comprehension all the essential elements of the genera above it, because an ‘animal’ is a ‘sentient, living, corporeal substance’; and this shows all the beings which are in some way similar to man – brutes, plants, inanimate bodies, substances. The specific difference ‘rational’ is the one distinctive essential element which distinguishes ‘man’ from every other ‘animal’; it thereby makes him a species of his own and separates him from every other ‘animal’ and also from every other genus or species, including plants and inanimate bodies.

 

“It will be noted that the generic idea must always be wider in extension than the idea to be defined; and the idea expressed by the specific difference must always be something not already contained in, but extraneous to, the generic idea. A definition, therefore, if it is to be a real and strict one, must be made up of two objectively different ideas – one wider and one narrower than the thing to be defined, so that the combination of both gives the exact designation of the thing. This, however, can never be the case in a definition of ‘being.’ ‘Being’ is the supreme idea, the widest and simplest and most indeterminate which the mind possesses; there can be no wider idea than ‘being.’ Consequently, the mind can find no idea which could, in any strict sense of the term, serve as a true genus for ‘being.’ The most we can attempt, then, is a descriptive definition, and even that will not elucidate the idea, since none of the ideas which could be employed will be clearer and simpler than ‘being’ itself. As was pointed out above, ‘being’ is the first idea in the logical order, and no other idea is intelligible without a previous understanding of the idea of ‘being.’”[81]

 

Being cannot be strictly defined for in order to define being one would need a more general concept within which being can be included. But no such concept exists since being encompasses the whole of reality. So, instead of a strict definition of being we can give various descriptions of being as “that which is” (ens est id quod est), “that something which is,” “that thing which exists.”

 

Being Not a Genus

 

Being is not a genus for a genus is contracted to a certain species by the addition of differences which are not actually contained within the genus. Now, as being actually contains all the differences of its inferiors it follows that it cannot be in any way a genus. “A genus is a notion which is applied equally and indeterminately to various things because it signifies only the characteristics which are common to them all and leaves out the features which differentiate them. The notion ‘animal,’ for instance, is a generic notion which is indistinctly applied to all beings which have sensitive life (e.g., man, horse, dog). In order to pass from a generic notion, such as ‘animal,’ to a more particular notion, such as ‘man,’ we need to add to the former new differentiating aspects which are not contained in the genus, namely, the differences which we left out in order to form the generic notion (e.g. ‘rational’ or other distinctive properties of the various species of animals). The notion of being is not a genus, since no differentiating elements can be added to it, which would not already be contained in it. The notion of animal does not include the differences which distinguish one animal from another. The notion ens, however, indicates not only what things have in common, but also their differentiating aspects; the latter (the differentiating aspects) also are, and are therefore included in the notion of ens.”[82]       

 

Real Being (Ens Reale)  

 

Common sense tells us that a real being (ens reale) is a being that really exists in transsubjective reality (i.e., the tall oak tree that exists out there in reality, that real dog that is barking in front of me). The tree that we are looking at, a real being that exists apart from us, has its own act of being (esse) that makes that tree to be. Now, when I know that tree and form a concept of “tree” in my mind, abstracting the universal essence from the individual concrete thing existing in reality, the mind leaves aside the act of being (esse), that is, it does not take in the esse of the tree that exists in reality. Therefore, when the intellect apprehends the concept of a certain thing, it is not entitled to affirm its existence (one would have to experience that thing in reality or find some evidence of its existence). Existence is never deducible from a mere definition of something.    

 

Possible Being

 

A possible being is a being that does not actually exist but is capable of existing. Thus, a possible being, as such, exists in the order of thought and not in the order of reality.  

 

Being of Reason (Ens Rationis)

 

Strictly speaking, an ens rationis or being of reason[83] is to be understood as that which exists in thought but is incapable of existing as such in the real order. A fictitious character that my imagination conjures up is an example of a being of reason. The logical entities studied in logic such as genus and species are also examples of beings of reason. Owens explains that beings of reason are “produced only in human reason. Human reason is able to combine notions each taken separately from reality, even though their combination in a real thing is impossible. A square circle, for example, cannot exist in reality. It is a combination of two notions, each taken from the shapes of real sensible things, but each of which negates the other. If a thing is circular, it is not square, and vice versa. The combination can exist only when human reason joins the two concepts in a way that is extrinsic to and contrary to their own natures. A centaur, likewise, is half man and half horse. It implies a nature that is simultaneously rational and non-rational. Either feature negates the other. Similarly, express negations like nothingness have no being in reality, yet they are given being in human thought when they are considered and discussed. Privations also, like blindness, when taken in themselves, and certain relations like identity, can have being only in human reason. They are not things that can exist as such in the real world. They are beings, but only beings of reason. In that sense they may legitimately be called things, even though they cannot exist in reality. Accordingly, nothingness, or a square circle, is something that can be reasoned about and discussed.”[84]

 

Even though these beings of reason exist only in the mind, they are not nothing; they have a certain actuality which consists in their being thought of by the mind. Now, an ens rationis can either be a first intention being of reason (either a negative being of reason or a positive being of reason, also called a ‘relation of reason’) or a second intention being of reason (a type of relation of reason), which is the object of the science of logic. Sanguineti explains that “some beings of reason are conceived by the mind when it understands reality directly. When I see the perfection of eyesight in a subject, for example, I also understand the nature of the privation of that perfection (blindness). Similarly, when I understand what ‘being’ means, I understand its negation (‘non being’). These beings of reason are called ‘first intention’ beings of reason since they are born of the first movement or intention of the mind when it knows reality. They include privations (blindness), negations (non-being) and many kinds of relations of reason (e.g., the relation between the left and the right side of a column, the relation of self-identity). Some of them, like the irrational numbers in mathematics, form part of the subject matter of scientific study.

 

“There is another kind of being of reason, conceived when the mind, in a second movement or intention, looks at its own ideas in order to study their different properties. These beings of reason (called ‘second intentions’ because they are the result of logical reflection) are the logical properties which constitute the object of the science of logic. Such are, for instance, the universals and the syllogisms. It is important to note that beings of reason always have some proximate or remote foundation in reality.”[85]

 

Elucidating upon first intention beings of reason (negative and positive) and second intention beings of reason (the object of logic), Henri Renard writes: “A being of reason can be considered as something positive or negative. If negative, it is either called a ‘negation’ or ‘privation.’ A ‘negation’ is the denial of a perfection in a being whose nature has no aptitude or need for such a perfection. The fact, for instance, that a man has no wings, is a mere negation. A ‘privation’ indicates a little more: it is the lack of a perfection for which the subject has real capacity (potency), perhaps a real need, as, for example, blindness in a man is lack of sight for which man has a real capacity.

 

“If, however, ‘being of reason’ is considered as something positive, it is called a ‘relation of reason’; for only a ‘relation,’ as we shall see later, can indicate something positive even when that something has no objective reality. And the reason is that the essence of a ‘relation’ is ‘order to’ (esse ad); and this ‘order to’ must be considered by the mind as something positive, even when it is not something outside the mind. ‘We may consider,’ explains the Angelic Doctor, ‘that in relations alone is found something which is only in the apprehension and not in reality. This is not found in any other genus; forasmuch as other genera, as quantity and quality, in their strict and proper meaning signify something inherent in a subject. But relation in its own proper meaning signifies only what refers to another.’[86] There are, however, two kinds of relations of reason. For instance, we may speak of the right and left of a column. Now this is undoubtedly only a relation of reason, for the column has neither right nor left, but we conceive an ‘order to,’ a relation, in reference to the position of one facing the column.

 

“Such concepts are evidently not erroneous, since we can find a foundation for them in the object. In the first place, it is clear that the reality of the object which lacks a perfection, whether that perfection be due or not, is a sufficient foundation for my concept of ‘privation’ or ‘negation.’ The reason for a ‘relation of reason,’ however, is a more subtle one. It is found primarily in the weakness of the human intellect, which, in its effort to understand ‘being’ in all its various aspects, needs to establish diverse ‘orders to’ and the relations of reason in order to acquire a more complete knowledge of the object.

 

“Besides these relations just mentioned, there is another sort of relation of reason which is the object of logic. It is generally called ‘second intention.’ The second intention is a certain relation which the mind places between natures which have been conceived, and in so far as they are understood, that is, in so far as they are in the mind. In other words, the relation is not understood to be between the concept and the object (res naturae), but between two or more concepts of natures. For example, the nature of animal as conceived is understood to be related as a genus to the nature of man and beast as conceived. These relations are ‘beings of reason’ in the strictest sense. The words of St. Thomas are extremely helpful to an understanding of this difficult relation: ‘Being of reason is properly said of those intentions, which the mind finds in the natures it has considered, as, for instance the intention of genus, species, and the like, which are not found in the things of nature but follow the consideration of reason. And such a being of reason is properly the subject of logic.’[87][88]

 

Intentional Being

 

Intentional being (or cognitional being), is any object in so far as it is known, consisting in the presence to awareness which an object has in the mind when known. This intentional or cognitional being is either sensible or intellectual. The sense image that I have of my dog Snoopy, for example, is an intentional being, and so is the intellectual idea of “dog” that I have in my mind.  

 

Analogy

 

Equivocal Terms. Equivocal terms are terms used with entirely different meanings. In univocal terms the same term, in at least two occurences of the term, has meanings completely different from one another. Examples of equivocal terms: 1. “Pen” as in the writing instrument, and “pen” as in pig pen which houses animals ; 2. “Bill” as in a piece of paper from a company showing what you owe, and “bill” as in the parts of a bird’s jaws ; and 3. “Seal” an emblem or figure used as evidence of authenticity, and “seal” the sea mammal that feeds on fish and has limbs reduced to flippers. The Angelic Doctor writes: “In the case of equivocity the same term is predicated of various things with an entirely different meaning. This is clear in the case of the term dog (canis), inasmuch as it is predicated both of a constellation and of a certain species of animal.”[89] 

 

Univocal Terms. A term is univocal if it signifies exactly the same concept, or essence, in (at least) two occurrences of the term. Univocal terms have one and only one meaning. They are constantly used in an identical sense. For example, when I say “A dog is an animal,” and “A cat is an animal,” “animal” in both propositions is univocal. Aquinas writes: “In the case of univocity one term is predicated of different things with absolutely one and the same meaning; for example, the term animal, which is predicated of a horse and of an ox, signifies a living, sensory substance.”[90]  

 

Analogical Terms. Terms are analogical[91] when the term, in at least two occurences of the term, has several meanings which are partly the same and partly different. Analogical concepts are predicated of their subjects in a way that is partly the same and partly different. Analogical terms share in the same perfection but have a diversity in the manner of possessing that perfection. For example, there is a difference between a good rock, a social good, and a good person. The metaphysical foundation of analogy lies in the different ways various subjects possess the same perfections. Different manners of being results in different manners of signifying. Now, an analogical term may be based either on the analogy of proportionality or on the analogy of attribution (of which there are two types, namely, the analogy of extrinsic attribution and the analogy of intrinsic attribution).[92] 

 

Analogy of Proportionality. In the analogy of proportionality, the analogous term is applied to unlike things because of some proportion or resemblance existing between them. A concept is predicated with the analogy of proportionality when several subjects possess a common perfection in ways that are not exactly but only proportionately the same. There can be an analogy of proportionality in the mathematical order, for example, with the proportion between quantities such as the double proportion obtaining in 2:1, 4:2, 8:4 and so on. These ratios are proportionately equal so we are able to say that 2:1 equals 4:2 equals 8:4. Though it is true that four is not equal to eight, nevertheless, the relation 4:2 is identical with the relation 8:4. Such an equality is termed a proportional equality. We also see the analogy of proportionality working in other fields such as that of philosophy. We can say, through a similarity of relations, that matter is to form as potency is to act.

 

In the analogy of (proper) proportionality “the nature signified by the concept is formally and intrinsically realized in each of the analogates according to a proportional similarity. Let us explain this definition: In the first place, the nature signified by the concept is intrinsically realized in each of the analogates. An example to the point would be the concept of life as predicated of plants, animals, man and pure spirits. Obviously, the life of plants, animals, man, and pure spirits is very different; yet the perfection signified by the concept of life is found in each of them.

 

“In the second place, the nature signified by the concept is formally realized in each of the analogates. This feature distinguishes analogy of proportionality from metaphorical analogy, in which only one of the analogates realizes this nature formally. Life, for instance, is found in plants, animals, and man in a formal sense, and not merely as a figure of speech.

 

“In the third place, the nature must be realized in the analogates according to a proportional similarity. This characteristic distinguishes analogy of proportionality from univocity. A nature can be realized formally and intrinsically either in exactly the same manner or according to a proportional similarity. If it is realized in exactly the same manner, the concept cannot be analogous, but is univocal because it does not vary. But a perfection can be realized also according to a proportional similarity. By this term we mean that in each of the analogates there exists a proportion or relation between two perfections or notes, and that these proportions or relations are similar. Hence it is no longer a question of one analogate being related to another, as is the case in analogy of attribution, but of a relation in one analogate being similar to a relation or proportion in another analogate. When, for instance, we predicate the term ‘living’ of plants, animals, and men, we do not consider the relations which these forms of life have to one another, but the fact that man’s nature is proportioned to the human mode of life as an animal’s nature is proportioned to a sentient mode of life, and the nature of a plant is proportioned to a vegetative mode of life. Thus in each of the analogates the concept of life is realized formally and intrinsically, but the content of this concept varies according to the subject under consideration.

 

“It should be clear that such an analogy is possible only in concepts which express a nature indeterminately, in such a way that the concept can be determined from within.[93] This determination takes place when the concept is predicated of one of the analogates. The concept ‘living,’ for example, implies a nature which is proportioned to self-movement, but it does not determine the kind of self-movement. But as soon as we predicate this concept of particular living things, we are referring to a definite type of self-movement, so that our concept undergoes a determination which makes it unsuitable for predication of another type of self-movement without being readjusted.”[94]

 

Metaphors are a type of analogy of proportionality (albeit improper). We say that hikers begin their adventure at “the foot” of the mountain, “foot” because of its resemblance to the position of the foot with regard to the human body. Graphic comparisons and parables also employ the analogy of improper proportionality.

 

Metaphorical analogy is called an analogy of improper proportionality wherein “the nature signified by the term is realized formally and intrinsically in one of the analogates, and in the other or others intrinsically and virtually, i.e., only with respect to a secondary characteristic, such as the activity, proper to this nature. Take for example, the term ‘lion.’ The nature signified by this term is realized formally and intrinsically only in the animal which we call a lion. We cannot call a man a lion in the formal sense, for a lion is essentially irrational, whereas man is essentially rational. However, it is proper to the nature of a lion to act courageously in the face of danger, or at least we consider this to be so. Hence we may fix our attention upon this secondary aspect of the nature of a lion and predicate the term ‘lion’ of a man who is courageous. In doing so we merely want to convey the idea that in the face of danger this man acts in the same way as a lion is supposed to act. Hence we say that he is a lion because of his resemblance to a lion in the order of activity. As far as the predication of the term ‘lion’ is concerned, it is clear that only a certain type of brute animal formally and intrinsically realizes the nature expressed by this term. Hence in predicating ‘lion’ of a man we have to keep in mind the subject of our predication and to make an adjustment in the predicate. Again, however, this adjustment is rather in the term than in the concept; for the nature signified by the term is realized formally and intrinsically only in the animal. Nevetheless, pure equivocation is avoided because we see a basis for predicating the same term of both animal and man. This basis lies in a similarity of both subjects in a secondary aspect of the nature ‘lion,’ namely, in the order of activity. It should be clear that it is impossible to define ‘lion’ as predicated of a man without the primary analogate (the brute animal) being taken into consideration. For the reason of the predication is precisely some aspect flowing from the nature of the primary analogate.”[95] 

 

Analogy of Attribution. In the analogy of attribution the analogous term is applied in an absolute sense to one thing and is then attributed to other things because of an intrinsic relation which they have towards the first. While analogy of proportionality merely compares different proportions, the analogy of attribution goes further, pointing to one of the terms of comparison as the principle of the rest. A perfection is predicated with the analogy of attribution if, among several subjects of a common perfection, there is one which possesses the perfection in all its fullness, while the rest possess it in derived manner or by what is called participation. In the analogy of attribution there is always a central and primary meaning by which the rest depend, and the analogical term is predicated beforehand of the subject (called the principal analogate[96]) of the principal meaning. With regard to the other subjects, called the secondary analogates, the analogical concept is predicated only posteriorly. The analogy of attribution involves the predication of a concept or term primarily to the principal analogate, and its posterior attribution to the other subjects by derivation. Now, the analogy of attribution can either be extrinsic or intrinsic.

 

Extrinsic Analogy of Attribution. In this type of analogy of attribution only the principal analogate properly and formally possesses the analogical perfection; the secondary analogates possess it only in an extrinsic and improper manner. Take, for example, the term “health.” Medicine is deemed “healthy” because it restores health. Climate is termed “healthy” because it is conducive to health. Food is termed “healthy” because it sustains health. Exercise is termed “healthy” because it promotes health, and complexion is said to be “healthy” because it indicates a healthy constitution. Medicine, climate, food, exercise, and complexion are said to be healthy only in an improper sense for they are the external causes of a healthy body.       

 

Intrinsic Analogy of Attribution. This type of analogy is the most important as it is of capital importance in describing the relation between God and His creatures. In the intrinsic analogy of attribution the analogical concept is properly predicated not only of the principal analogate but also of the secondary analogates because the former really is the cause of the perfection of the latter. For example, we say that creatures “are” and God “Is” ; being is said principally of God, the Supreme Being, for His Being is His Essence. However, being is properly predicated of created beings inasmuch as they received their being from the Supreme Being. Creatures “have” being by participation, while God “Is” being. The fundamental basis of the intrinsic analogy of attribution is the relations of causality among beings. It is based on the imperfect similarity or likeness of the effect to its cause. Sanguineti gives us some observations regarding this point: “a) Since one cannot give what one does not have, at least some perfections of the efficient cause will necessarily be reflected in its proper effects. The efficient cause is, therefore, also an exemplary cause of its proper effects. It follows that by studying the latter, we can, using the analogy of attribution, arrive at some knowledge of the former. It is in this way that we arrive at an analogical knowledge of the nature of God on the basis of the manifold perfections we find in creatures; b) Consequently, analogy of attribution implies both similarity and dissimilarity. The analogical concept is predicated per prius of the cause, and per posterius of the effects. It is partly attributed to the effects inasmuch as they are similar to the cause ; but it is partly not attributed to them since they are also unlike the cause. Hence, the universe is, at one and the same time, like God and unlike Him; c) The foundation of the analogy of attribution is not an abstract idea but a real cause, the cause of the participated likenesses of the perfection in the secondary analogates. For example, if being is common to God and the world, it is not because the abstract notion of being is found in both of them, but because the being of the world points to the Being of God as its principle and cause. It would be an error to establish the foundation of this analogical community of being on the most abstract concept of being-in-general (esse comune), which is necessarily univocal; d) The ontological priority of the principal analogate does not always mean gnoseological priority, for sometimes it is only through their effects that we acquire a knowledge of the causes. This is the case with our knowledge of God, the principal analogate of being. Though first in the ontological order, God comes after creatures in the noetical order since it is the latter that we first know and apply names to. In the order of knowledge, therefore, the meaning of our notions of being, goodness and truth applies primarily to creatures.”[97]

 

Being is Analogical

 

When we say that “God is Being” and that “man is a being”, being here is predicated of their subjects analogically. Not equivocally as many of the nominalists and atomistic empiricists maintain. Nor univocally as Parmenides held, for “if being were to be understood in a univocal manner, then all reality would be deemed to be in the same manner, which would ultimately lead to monism. Everything would be seen as identically one, and therefore, there would be no difference between God and creatures (pantheism). Taking into account the analogical notion of being, however, we can speak about God and creatures as beings, maintaining at the same time the infinite distance between them. By way of analogy, created being leads us to the knowledge of the divine being and its perfections. That is why this question is of utmost importance for metaphysics and theology.”[98] To sum up, we say that being is analogical by an analogy of proper proportionality and an analogy of intrinsic attribution.


 

 

CHAPTER 2

 

THE PRINCIPLE OF NON-CONTRADICTION

    

 

The First of All Principles

 

A principle is that from which something else proceeds.[99] Now, the first of all principles is the principle of non-contradiction.[100] All other principles are founded upon this first of principles. St. Thomas writes that “what falls first under our apprehension is being, the understanding of which is included in anything whatsoever that a person may apprehend. And therefore the first indemonstrable principle is that there is no affirming or denying at the same time, which (principle) is founded on the notion of being and non-being; and on this principle all others are founded.”[101]

 

Though the first metaphysician Parmenides of Elea (c. 520-440 B.C.) gave what was to be the first formulation of the principle of non-contradiction, he understood this principle in such a rigid way so as to exclude all relative non-being, ending up in a univocal monism. It was to be the greatest of the ancient philosophers, Aristotle of Stagira (also known as “the Stagirite”), who gave the world the first adequate formulation of this principle.   

 

Koren explains that the principle of non-contradiction is the first of all principles for: 1. it flows immediately from the notion of being; and 2. it is the foundation of all the other principles: “With regard to the first point, it is clear that the first principle will have to express a relationship of the concept of being to another concept. For by its very nature a complex principle must be concerned with the relationship of two concepts. Now from the concept of being the intellect derives immediately the concept of non-being as its contradictory. Upon apprehending these concepts the intellect sees at once that one is not the other, that being is not non-being. Hence the principle of non-contradiction flows immediately from the concept of being.

 

“The second point, that the principle of non-contradiction is the foundation of all other principles, follows from the first. For if the principle of non-contradiction flows immediately from the first concept, it is clear that no other principle is prior to it. Moreover, any other principle either presupposes the principle of non-contradiction or is merely a different formula of the same.”[102]             

 

As being is the first notion that our intelligence grasps, and which is implied in any consequent notion, there is also an intellectual judgment (the second operation of the mind) that comes naturally first and which is presupposed by all other consequent judgments: “It is impossible to be and not be at the same time and in the same respect.” This first judgment is called the principle of non-contradiction for it expresses the most basic condition of things, that is, that they cannot be self-contradictory. Such a principle is founded upon being and expresses the consistency of being and its opposition to non-being. There is a radical incompatibility between being and non-being, for the act of being (esse), act of acts and perfection of perfections, confers upon being (ens) a real perfection that is absolutely opposed to the privation of that perfection.

 

Why do we say “at the same time” in our formulation of the first principle? Because it is not at all contradictory, for example, for the leaves of a tree to be green in one season and yellow in the next. Therefore, we should say: “The leaves of the tree are green today, in this fifth day of the month of June.” Why “in the same respect” in our formulation? Because it is not at all contradictory, for example, for a student to be learned in algebra and ignorant in English literature. If we affirm that the student is learned, we must specify what particular area he is learned in.      

 

There are different ways of expressing this first principle. It is above all a judgment that concerns reality itself; it regards what is. Hence, the more profound formulations of the principle of non-contradiction are metaphysical in nature. For example, the Stagirite states in the fourth book of his Metaphysics that “it is impossible for one and the same thing to be and not to be,”[103] and further on, that “it is impossible for a thing to be and at the same time not to be.”[104]

 

The principle of non-contradiction is the supreme law of reality (the order of being or the ontological order) and not just a simple postulate or axiom of our mind. But, since the mind of man is geared to know reality as such, it is, in a derivative way, the first and supreme law of logic. Violate this supreme law and one collapses into a state of mental anarchy. Since the first principle of reality is also the first principle of thought we are able to say that “we cannot both affirm and deny something of the same subject at the same time and in the same sense” as well as to say that “contradictory propositions about the same subject cannot be simultaneously true.” The human mind is subject to the principle of non-contradiction: it cannot know being as self-contradictory precisely because being cannot be self-contradictory. If our mind attempts to deny this principle our reasoning falls into absurdities.

 

The Objective Validity of the Principle of Non-Contradiction in the Order of Being and Its Denial by the Philosophers of Contradiction

 

A number of Ancient Greek philosophers have denied the principle of non-contradiction, such as Heraclitus of Ephesus (550-480 B.C.), the Sophist Gorgias (c. 483-375 B.C.), and the Skeptic Pyrrho of Elis (c. 360-270 B.C.). Heraclitus maintains that all is change and flux (panta rei), that there are no stable natures in things. The nihilist Gorgias, the most radical of the Sophists, presents the following three theses: “First: nothing exists. Second: if anything existed, it cannot be known by man. Third: if it can be known, it cannot be transmitted and explained to others.”[105] Pyrrho skeptically maintains that one cannot know anything whatsoever about reality, and therefore has recourse to an absolute silence, abstaining from all judgments so as to achieve a perfect indifference to all things (ataraxia).

 

The principle of non-contradiction is not just an internal, subjective, law of logic but is based on reality itself. The German transcendental idealist Immanuel Kant (1724-1804) taught that the first axiom principle of non-contradiction was at the foundation of all analytic judgments, and that this principle was itself an a priori analytic judgment that has nothing to do with synthetic judgments that are formed on the basis of experience. Consequently, he mistakenly held, against the realist position, that the principle of non-contradiction was valid only in the logical sphere, not in reality; it would only be a negative logical condition for correct thinking.[106] The transcendental “Thomist” Joseph Maréchal, S.J. (1878-1944) not only corrupted realism, adopting the Cartesian point of departure, but, following Kant, taught that the principle of non-contradiction was but the subject’s expression of a subjective necessity. The prolific author Karl Rahner, S.J. (1904-1984), a disciple of Kantian and Heideggerian thought and Marechal’s “transcendental Thomism,” also held that that the principle of non-contradiction was to be found only in the subjective order of our minds and not in the objective order of reality.[107]

 

Henri Bergson’s (1859-1941) vitalist evolutionism also erroneously denies the objective validity of the principle of non-contradiction in the name of becoming. For him, there are no concrete individual things but rather actions, real being defined as not that which is, that which exists, but rather that which becomes and continuously is in flux. He writes: “There are no things, there are only acts; things and states are merely modes of thinking, which our mind derives from the idea of becoming.”[108] Consequently, there can be no real distinction between “a glass of water, water, sugar, and the process by which sugar is dissolved in water.”[109] Such reasoning is tantamount to affirming that a dog is a dog and no dog at all since it is in constant flux and therefore has no proper nature. Everything would be in everything. Edouard Le Roy (1870-1954), a follower of Bergson, likewise denied the objective validity of the principle of non-contradiction in the name of becoming: “the principle of non-contradiction is not as universal and necessary as has been believed; its application is limited; it is restricted and circumscribed in meaning. Being the supreme law of speech, but not of thought in general, its influence extends merely to what is static, morcellated, immobile, in a word, to the things endowed with identity. But just as there is identity in the world, so also there is contradiction. Such are those fugitive fluxes, as becoming, duration, life, which of themselves are not of the rational order, and which speech transforms so as to incorporate them into contradictory schemata.[110] For Le Roy, our mind merely objectivates the universal becoming that is reality for the needs of speech and for the practical needs of everyday life; in such a way does the mind pretend to submit all that is real to the principle of non-contradiction. The consequences of this type of reasoning, this manner of violation of the principle of non-contradiction, particularly in the field of morality, is disastrous. Morality becomes immorality for there is no more a distinction between objective good and evil than there is a distinction between being and non-being. Jean Weber, himself of the Bergsonian school, gives us the moral consequences of accepting the views of Bergson and Le Roy: “Morality, in planting itself on a terrain from which invention grows in all its vigour, immediately and full of life; in manifesting itself as the most insolent encroachment of the realm of the intellect upon spontaneity, was fated to encounter the continual contradictions of that undeniable reality of dynamism and creation which is our activity…Confronted with these morals of ideas, we outline morality, or, more correctly, the unmorality of the act…We call ‘good’ whatever has triumphed. Success, provided it is fierce and implacable, provided the vanquished are completely defeated, destroyed, abolished beyond hope – success justifies everything…The man of genius is profoundly immoral, but for anyone to be immoral is not the proper thing…‘Duty’ is nowhere in particular, and yet it is everywhere, for all actions possess absolute value. The repentant sinner deserves all the anguish of his contrite soul, because he was not strong enough to transgress the law, and unworthy to be a sinner.”[111]                

 

The absolute idealist Georg Wilhelm Friedrich Hegel (1770-1831) attempted to deny the objective reality of the principle of non-contradiction as is attested to here in a passage from his book Logic[112]: “The distinction between Being and Nothing is, in the first place, only implicit, and not yet actually made: they only ought to be distinguished. A distinction, of course, implies two things, and that one of them possesses an attribute which is not found in the other. Being, however, is an absolute absence of attributes, and so is Nothing. Hence, the distinction between the two is only meant to be; it is quite a nominal distinction, which is at the same time no distinction. In all other cases of difference there is some common point which comprehends both things. Suppose, e.g., we speak of two different species: the genus forms a common ground for both. But in the case of mere Being and Nothing, distinction is without a bottom to stand upon: hence, there can be no distinction, both determinations being the same bottomlessness… Nothing, if it is thus immediate and equal to itself, is also the same as Being is…In Being we have Nothing, and in Nothing Being…In Becoming the Being which is one with Nothing, and the Nothing which is one with Being, are only vanishing factors; they are and they are not.”[113] In the light of realism, such reasoning, a flagrant violation of the first of all principles, is simply absurd and destroys the foundations of all knowledge, whether scientific or philosophical.

 

Jean Weber, of the school of Bergson, sums up Hegel’s denial of the objective validity of the principle of non-contradiction in the name of the very idea of being: “Being is the most universal of all notions, but for this very reason it is also the poorest and the most negative of notions. To be white or black, to have extension, to be good, means to be something; but to be without any determination, is to be nothing, is simply not to be. Pure and simple being is, therefore, equivalent to not-being. It is at one and the same time itself and its contrary. If it were merely itself, it would remain immobile and sterile; if it were mere nothingness, it would be synonymous with zero, and in this case also completely powerless and infecund. It is because it is the one and the other that it becomes something, another thing, everything. The contradiction contained in the notion of being resolves itself into becoming, development. To become is at the same time to be and not to be (that which will be). The two contraries which engender it, namely, being and non-being, are rediscovered, blended and reconciled in becoming. The result is a new contradiction, which will resolve itself into a new synthesis, and thus the process will continue until the absolute idea is reached.”[114]

 

The great 20th century French Thomist Reginald Garrigou-Lagrange (1877-1964) objects to such fallacious reasoning, writing: “To perceive the sophism contained in this argument, we need only to cast it into syllogistic form: Pure being is pure indetermination. But pure indetermination is pure non-being. Therefore, pure being is pure non-being. The middle term, ‘pure indetermination,’ is used in two different senses. In the major it means the negation of all determination, generic, specific, or individual, but not the negation of (ideal or real) being, which transcends the generic determinations of which it is susceptible. In the minor, on the other hand, pure indetermination is not only the negation of all generic, specific, and individual determination, but also implies the negation of any further determination of which being is capable. Therefore, the argument amounts to this: that pure being is undetermined being; but undetermined being is pure non-being. The minor is evidently false.”[115] Garrigou-Lagrange also adds: “Besides, there is no apparent reason why becoming should emerge from this realized contradiction, this identification of contradictories. On the contrary, we must hold with Aristotle that ‘to maintain that being and non-being are identical, is to admit permanent repose rather than perpetual motion. There is in fact nothing into which beings can transform themselves, because everything includes everything’(IV Metaph., c. v).”[116]    

 

Frederick Wilhelmsen (1923-1996) explains that Hegel’s panlogicism was a serious attempt to deny the objective validity of the principle of non-contradiction: “Hegel identified the orders of thought and existence. Being functions the way thinking functions, taught Hegel, because being is a ‘concretization’ of absolute spirit. In thought, said Hegel, every proposition has its contradictory. Posit any judgment and you thereby posit its opposite. On this point, Hegel merely repeated a truth known to logicians since the time of Plato. Aristotle systematised this law of the mind in his well-known Square of Opposition: The proposition ‘every cow is black’ is contradicted by ‘some cow is not black’; ‘no academician is a fool’ is contradicted by ‘some academician is a fool,’ and so forth. Hegel pushed this opposition of judgments to the order of being itself. ‘Being is being’ is contradicted by ‘being is not-being.’ Given the first proposition, the second automatically follows. Therefore being contradicts itself, and this contradiction is the most fundamental law of the spirit. If we grant Hegel’s identification of spirit and reality, his position makes good sense. It was the only way he could account for progress in the universe, for change. If the real is basically the same thing as the rational, one of two conclusions follow: either the real is given once and for all or it is not. If we grant the first supposition, we must conclude – with Hegel – that spirit never gets anywhere at all; spirit does nothing but analytically dissect an order already given at the outset, an order of ideas and laws to which nothing new is ever added. Refuse the first supposition because of the fact of change in the world and it follows that reality could only advance by contradicting itself. Begin with a given – call it A – and assume that only A is given. How do we get from A to B, when B is not given? We move from A to B only if A contradicts itself. Fundamentally, B is nothing but A’s negation of itself; B is non-A. In this fashion we can move from one point in the real order to another. We can account for change, for the advance of spirit. If we refuse Hegel’s identification of spirit and reality, if we judge his position in the light of realism, we can easily see that his error consisted in treating the metaphysical order, the real order, as though it were the logical. But the whole point about being, in reality, is that it is being. The contradictory to being, not in the order of ideas but in the order of things, would be non-being. But in reality there is no such ‘thing’ as an existing non-being. A man does not need an armory full of logical and dialectical weapons to understand this; all he needs is some existing thing which he can contemplate for a short time. Concentrate for a moment on the piece of paper before your eyes; formulate the proposition, ‘the paper exists’; now contradict the first proposition with ‘the paper does not exist.’ The two judgments contradict each other in the logical order, in your mind. The contradiction exists mentally because the two judgments can be entertained as logical opposites. Now return your attention to the piece of paper itself, not as it exists in a proposition in your mind, but as it is in itself. What is the contradictory of the existence of the paper in the order of being? In that order, the order of things as they exist beyond your thinking of them, there simply is no contradictory to the piece of paper. The non-existence of the paper that exists is a metaphysical zero. To see this is to see that Hegel confused the two orders.”[117]            

 

For Garrigou-Lagrange, “this absolute intellectualism of Hegel is no less destructive of all knowledge than is the anti-intellectualism of Heraclitus and Bergson. All reasoning presupposes that every idea employed in the process represents a reality, the nature of which remains the same; but for Hegel, the principle of identity (non-contradiction) is merely a law of inferior logic, of the mind working with abstractions, and not a law of superior logic, of reason and reality. ‘From this it follows,’ as Aristotle remarked (IV Metaphy., c. iv), ‘that one can with equal right affirm or deny everything of all things, that all men tell the truth and that all lie, and that each one admits that he is a liar.’ For the rest, Hegel himself acknowledges ‘that if it is true to say that being and non-being are one and the same, it is also true to say that they differ, and that the one is not the other.’[118] It follows from this that, according to Hegel, nothing can be affirmed and everything can be affirmed. If this attitude does not destroy all science, it cannot at least be said to have more than a relative value, and hence to possess nothing more than the name of science.”[119]   

 

For Hegel, reality is not grasped in its concreteness, in its substantiality. Rather, substance and essence is negated in favor of contradiction and becoming. The fundamental principle of the Hegelian dialectic is that the essence of being is contradiction. For him, the antinomical dialecticism of contradiction is not something by which change is realized in a substance, respecting, of course, the concrete individuality of substance, nor is it a simple function or law of thought; rather, it is the very essence of reality itself and also of thought itself. Hegel not only makes the dialectic a law of thought; it also becomes a metaphysical principle of reality. He identifies metaphysics with logic and makes logic metaphysics itself. Each thing – a dog, rat, a cow, for example – is and is not itself; in fact, its true being is becoming.        

 

Neo-Positivists (or logical positivists), like Moritz Schlick (1882-1936), Rudolf Carnap (1891-1970) and Ludwig Wittgenstein’s (1889-1951) neo-positivist “first period” (also known as the “First Wittgenstein”), dismiss the principle of non-contradiction maintaining that this principle cannot be validated by the principle of verification, which states that all meaningful propositions must be verifiable in sense experience. Thus, the principle of non-contradiction would be, in their eyes, meaningless. The problem with the principle of verification is that the principle itself cannot be verified in sense experience, it being a metaphysical principle transcending sense knowledge. Regarding this matter Wilhelmsen writes: “Although Hegelian contradiction is still maintained by the Marxists, a more popular attack on the principle of non-contradiction has come from the school of logical positivism. This school maintains that the principle of non-contradiction is meaningless. The principle is discarded for a new first principle which the positivists call ‘the principle of verification’ or ‘verifiability.’ For the positivists, all thought is nothing but the way in which we order our sense experiences: There are no ‘things’ in a realist sense of the term; there are only ‘facts’ which are the data given sensation. Scientific law and all other ‘meaningful’ discourse rise out of man’s attempt to order his experience for the sake of his practical mastery over life. A statement has meaning, makes sense, only if it can be reduced to some sense experience with which it is directly or indirectly identifiable. Positivists do not mean merely that all human knowledge begins in sensation which alone confronts existing things; they mean that every affirmation and negation making sense is composed of a subject and a predicate which symbolize some sensorial data experienced or capable of being experienced. But the proposition ‘being is being,’ while including sensible being, transcends the material order; it does not point to sensations or to ‘data,’ but to the truth that things are, that they exist. Therefore, say the positivists, it is meaningless: not false, not true, just gibberish.

 

“Through this attack on the primacy of being, the logical positivists sweep away all metaphysical and religious discourse. The belief that there is a God is not condemned as false; it is just dismissed as nonsense, along with the atheist contention that there is no God. In this way, positivism cuts beneath the great debate about the final meaning of human existence that has engaged civilized man since the day he discovered he had a soul. Positivism is a far more popular philosophy today than idealism…

 

“If all propositions must be verified in sense experience, then why not the principle of verification itself? The principle is a complex of meaning, no element of which is identified with sense experience. ‘Every meaningful proposition is verifiable in sense experience.’ The predicate, ‘sense experience,’ is not sensible; it is an abstract, intelligible content; it is not identified with any given sense experience. ‘Meaningful’ is not a sense experience. What is the ‘meaning of meaning’? Whatever it might be, it cannot be identified and understood simply by pointing at something and punching it. The whole proposition might be said to stand for the totality of sense experiences and thus to symbolize them all. If this is so, then there is a ‘meaning’ beyond experience, and this ‘meaning’ is meaning itself.

 

“The amusing thing about positivism is that it proceeds to deny the intelligence by using the intelligence denied. It sets up an elaborate criterion to destroy the intellect, and the criterion turns out to be highly intellectual in structure. Positivism is, therefore, self-contradictory, self-destructive, a system that dissolves from within once it is seen to be what it is.”[120]    

 

The Self-Evident Nature of the First Principle

 

The principle of non-contradiction is naturally and spontaneously known by all men through experience. It is self-evident to all. Since it is the first judgment, this first principle cannot be demonstrated by means of other truths prior to it. When a truth is self-evident, it is neither necessary nor possible to prove it; only something which is not immediately evident requires proof. That the principle of non-contradiction is not demonstrable because of its self-evidence is not a sign of its imperfection; rather it is a sign of its perfection. Koren explains how the principle of non-contradiction is an analytic principle,[121] writing: “The question may be asked as to how we know that the principle of non-contradiction is true.[122] At first sight it is clear that it will be impossible to offer any direct demonstration of this principle. For in a direct demonstration we derive the truth of a conclusion from certain premises, i.e., from truths known to us prior to the truth of the conclusion; now no truth can be prior to the first principle; hence a direct demonstration of the principle of non-contradiction is not possible.

 

 

“It is likewise impossible to demonstrate the principle indirectly. For in an indirect demonstration we show that the denial of a proposition implies a contradiction, i.e., is against the principle of non-contradiction. Hence any indirect demonstration presupposes that the principle of non-contradiction has already been admitted.

 

 

“However, demonstration is not the only way in which we can be certain of the truth of a judgment. Sometimes a judgment may reveal itself to the mind as true by a mere analysis of its terms. To be certain of the truth of such a judgment, we only have to understand its subject and predicate, and our intellect is no longer able to doubt or reject it. Take, for example, the judgment ‘the whole is greater than its parts.’ Once we understand the meaning of the terms used in this proposition we cannot escape the judgment that the whole is greater than any of its parts. Hence an analytic principle is self-evident.

 

 

“That the principle of non-contradiction is such a self-evident principle should be clear. Once we understand the meaning of the terms ‘being’ and ‘non-being,’ our intellect sees at once the truth of the statement that one is not the other. Moreover, it would be impossible to doubt or deny the principle of non-contradiction. For if I say ‘I deny or doubt the principle of non-contradiction,’ I admit that to deny or to doubt is not the same as not-to-deny or not-to-doubt, and thus my very denial or doubt shows that I admit what I deny or doubt. For this reason this principle has been appropriately nicknamed ‘the boomerang principle,’[123][124]  

 

Reasons for Defending the Principle of Non-Contradiction

 

In the Metaphysics, Aristotle replies to those who would be so foolish as to negate the principle of non-contradiction, writing that “in order to deny this principle, one has to reject all meaning in language. If ‘man’ were the same as ‘non-man,’ it would not, in fact, mean anything at all. Any word would signify all things and would not, therefore, denote anything; everything would be the same. Consequently, all communication or understanding between persons would be impossible. Thus, whenever anyone says a word, he is already acknowledging the principle of non-contradiction, since he undoubtedly wants the word to mean something definite and distinct from its opposite. Otherwise, he would not even speak….Anyone who rejects this first principle should behave like a plant, since even animals move in order to attain an objective which they prefer over others, as when they seek food.”[125] “Besides, denying this principle in fact implies accepting it, since in rejecting it, a person acknowledges that affirming and denying are not the same. If a person maintains that the principle of non-contradiction is false, he already admits that being true and being false are not the same, thereby accepting the very principle he wishes to eliminate.”[126] 

 

Garrigou-Lagrange summarizes for us Aristotle’s eight principal reasons for defending the necessity and objective validity of the principle of non-contradiction: “(1) to deny this necessity and this validity would be to deprive words of their fixed meaning and to render speech useless; (2) all idea of the reality of an essence, or thing or substance as such, would have to be abandoned; there would be only a becoming without anything which is on the way of becoming; it would be like saying that there can be a flux without a fluid, a flight without a bird, a dream without a dreamer; (3) there would no longer be any distinction between things, between a galley, a wall, and a man; (4) it would mean the destruction of all truth, for truth follows being; (5) it would destroy all thought, even all opinion; for its very affirmation would be a negation. It would not be an opinion which Heraclitus had when he affirmed that contradictories were true at the same time; (6) it would mean the destruction of all desire and all hatred; there would be only absolute indifference, for there would be no distinction between good and evil; there would be no reason why we should act; (7) it would no longer be possible to distinguish degrees of error, everything would be equally false and true at the same time; (8) it would put an end to the very notion of becoming; for there would be no distinction between the beginning and the end of a movement; the first would already be the second, and any transition from one state to another would be impossible. Moreover, ‘becoming’ could not be explained by any of the four causes. There would be no subject of becoming; the process would be without any efficient or final cause, and without specification, and it would be both attraction and repulsion, concretion as well as fusion.”[127]

 

 


CHAPTER 3

 

SUBSTANCE AND ACCIDENTS

 

 

We initially arrive at a knowledge of substance from the observation of accidental changes in nature. A father’s face, for example, gets red because his son bumped his favorite car. The passage from the father’s originally white face to a red face to a white face again does not obviously destroy the individual being that is the father. He doesn’t turn into a frog or into a chair. Therefore, this accidental modification that he undergoes without destroying his being an individual man reveals a substratum that remains in essence the same throughout the accidental changes. There is revealed, in the accidental alteration that we have observed, a stable, permanent substantial core, called the substance,[128] and certain secondary changeable perfections, called the accidents.

 

Substance

 

Like being, substance cannot be strictly defined. But substance may be broadly defined as that reality to whose essence or nature it is proper to be by itself and not in another subject. Now, since the substance is the core of a thing that weathers the various accidental modifications, it is the most important element in each thing. There are two basic aspects of substance: 1. The substance is the substratum, the subject, that supports the accidents; and 2. Substance is something subsistent. This means that it does not exist in something else but is by itself, not needing to inhere in another like the accidents do. A dog, for example, is a substance since it subsists, having its own being distinct from the being of anything else. The brownness of the dog, however, doesn’t subsist in itself but needs to inhere in a subject. We say “This brown dog.” The broad definition of substance is taken from this second fundamental aspect of substance. Psychologically, substance as the “substratum of the accidents” is prior to substance as “something whose nature or essence it is to be by itself and not in another subject.” That is, we initially arrive at a knowledge of the substance through its function of supporting the accidents. However, metaphysically or ontologically, that is, in the order of reality, substance as “something whose nature or essence it is to be by itself and not in another subject” is prior to substance as the “support of the accidents,” because in order for substance to act as the support of the accidents it must first of all “be by itself and not in another subject,” that is, it must be capable of supporting itself. If substance is capable of having an essence or nature to be by itself and not in another it will be capable of supporting the accidents. Being capable of supporting the accidents is a property of the substance whose real nature or essence is to be by itself and not in another subject. This is why the broad definition of substance is taken from the second of our aspects of substance.            

 

Classification of Substances

 

Substances are classified into the following groupings: 1. incomplete substance and complete substance; 2. material substance and immaterial substance; 3. simple substance and compound substance; and 4. primary substance and secondary substance.

 

1. Incomplete Substance and Complete Substance. An incomplete substance is one whose nature demands that it be co-joined with another substantial co-principle, so as to be able to constitute a single complete substance. Matter taken by itself and form taken by itself are examples of incomplete substances. A human soul taken in itself is an incomplete substance, and a human body taken in itself is an incomplete substance. The human soul and the human body taken together constitute the single individual human person, a complete substance, that rational suppositum. A complete substance is one that does not need to be co-joined with the another substantial co-principle so as to constitute a single individual substance. It exists in such a manner that its nature does not demand a further union with a substantial co-principle. A dog, a rat, a horse, and an apple are all examples of complete substances.

 

Now, an incomplete substance may be incomplete either in the line of ‘substantiality’ or in the line of ‘specific perfection.’ An animal or brute ‘soul’ (substantial form of the animal body) is an example of the former type of incomplete substance, while the human soul regards the latter type of incomplete substance. Bittle explains that a substance is incomplete “in the line of substantiality, when it cannot perform any functions of the complete substance alone; it must always be united with its substantial co-principle. In this way, the brute soul and plant soul cannot exist outside the matter which they inform and cannot, therefore, be active in any manner unless united with matter; the functions of these types of being are such that they are dependent on matter at all times for their existence. Matter, the other co-principle, is incapable of performing any activity of its own, because it is altogether indeterminate and cannot exist except in conjunction with a substantial form or soul. Matter and form are the two substantial co-principles which unite to constitute a bodily substance; and in every bodily substance below the level of man these substantial co-principles are incomplete in the line of substantiality.

 

“A substance is incomplete in the line of specific perfection, if it can, when alone, perform some but not all activities proper to the complete substance. Thus, the human soul, being spiritual (as will be shown in rational psychology), can survive the dissolution of the body and in this disembodied condition perform some functions proper to man, for instance, thinking and willing. This is possible because such functions are spiritual and as such intrinsically independent of matter. Other operations, however, like nutrition and sense-perception, demand the participation of bodily organs and cannot be performed by the soul alone. Man, as man, though, must be able to perform all three types of activities – vegetancy, sentiency, and rationality. Hence, man’s soul is complete in the line of ‘substantiality,’ because it is independent of the body in its existence; but it is incomplete in the line of ‘specific perfection,’ because it cannot perform all human operations independent of the body.”[129] The reason, of course, why the human soul can continue in existence after the dissolution of the human body is because it has the act of being (esse) of its own given to it by God, Pure Act of Being.  

 

2. Material Substance and Immaterial Substance. A material substance is a substance that is either composed of matter or dependent intrinsically, for its being and activities, upon matter. A substance which is matter is called a “bodily” substance or simply a “body.” That substance which is not matter but is intrinsically dependent upon matter is properly called a “material” substance. A rock, a tree, a dog and a horse are all examples of material substances. An immaterial substance, on the other hand, is a substance which is not composed of matter (either in whole or in part, since it is simple, having no parts) nor intrinsically dependent upon matter for its existence and proper operations. Human souls, as well as the separate substances (the angels), are all immaterial substances.   

 

3. Simple Substance and Composite Substance. Complete substances are either simple or composite in nature. A complete substance is simple when it does not consist of entitatively distinct substantial parts. Examples of simple substances: the angels and God. These simple substances are called pure spirits. A composite substance, on the other hand, is a complete substance consisting of incomplete substantial parts, entitatively distinct among themselves in such a way that their union results in a single unified nature. A human person, for example, is a composite substance, made up of a human body united with a human soul (which is the substantial form of the body). 

 

4. Primary Substance and Secondary Substance. According to Aristotle, a primary substance (also called first substance) is the individual thing existing in extra-mental reality. That real dog Fido, for example, as he exists as an individual concrete being in reality, is a first or primary substance. A secondary substance (or second substance), on the other hand, is the universal notion of the existing thing, that substantial reality, as conceived by the mind. It is a universal and not the individual existing thing in reality. For example, the universal notion “dog” as a mental word that grasps the essence of dog, is a second or secondary substance.

 

Erroneous Views Regarding Substance

 

Descartes on Substance. Descartes erroneously defined substance as “a thing which exists in such a way that it does not need any other thing to exist.”[130] But this can apply only to God since it deals with an absolutely independent substance. He does say that this applies to God only, but then contradicts himself by maintaining that there are finite substances which require God’s power to exist. He reduced corporeal substances into res extensa (extension), thus reducing a substance into an accident. Regarding man, Descartes believed that he was of two substances, namely res extensa (extension) for the human body, and res cogitans (thought) for man’s soul. Again, these two “substances” that he is talking about are really two accidents. Though he speaks of “man” as consisting in two substances, res cogitans and res extensa, the “human person,” for Descartes, consists in his soul, but this soul, in turn, is identified with res cogitans or thought. Realistic philosophical anthropology, instead, maintains a strict difference between the soul, a substance (albeit incomplete, but having its own act of being), and thought, which is an accident (the product of our operative power of intellect, another accident, which is an immaterial faculty of the rational soul, substantial form of the body). The Cartesian human person is thus reduced from being initially two accidents to one accident (self-consciousness). Gone is the realistic view of man as an hylomorphic composite of body and soul, two incomplete substances, but together forming the one complete compoite substance of man, the indvidual substance of a rational nature. 

 

Spinoza on Substance. Spinoza writes that “by substance I understand that which is in itself and is conceived by itself; in other words, that whose concept does not need the concept of any other thing from which it must be formed.”[131] He takes Descartes’ definition of substance as a given, which would apply only to God, and concludes that there is really only one substance, the Divine Substance, which is God or Nature (Deus sive natura), all that is not God being but modes of the one Divine Substance. This position is obviously pantheistic.

 

Critique of the Spinozian Monistic Conception of Substance. Contrary to Spinozian monism, God is not identified with Nature; He is infinitely distinct from the world, whose finite and imperfect beings merely participate in the act of being given to them by the Infinite Being, the Pure Act of Being, in whom esse and essence are identified. To say, as Spinoza does, that there is only one Substance (Deus sive Natura), does violence to the testimony of common sense. Everyday experience shows that there are many things in the world, distinct from one another because of their specific essences, and those of the same form (apple, horse, cat, etc.) are many because their form is received in different parcels of matter (matter is the principle of individuation[132]). If the world were identical with God, the world would necessarily be a single being, for God is Himself supremely one, undivided and indivisible.[133] But such a position blatantly contradicts both the testimony of the senses and of reason. At the foundations of Spinoza’s substantialistic pantheism lie the erroneous notions of substance and subsistence (which he inherited from Descartes), and his failure to understand the real distinction of essentia and esse in creatures (finite beings, diverse in essence, only participate in esse; they merely have esse by participation). Hart explains: “But whether a substance (an ens per se) is also an Ens a Se, that is, a being in whom existence is intrinsic and proper to its nature or essence, will be quite a distinct problem from that of the constitution or nature of substance as such. It will involve the question as to whether the substance or essence is in potency to an act of to be received into this substance (and thus at the same time a principle of limitation and therefore multiplication), or whether it is a substance or essence identical with its act of to be (and therefore not a principle of limitation and multiplication). The substances of our immediate experience are all of the former character, namely, principles of limitation. This accounts for their multitude. They are therefore finite predicamental substances. They also point to the necessity of inferring the existence of a substance which is not a principle of limitation but is identical with its act of to be and without which the limited substances could not exist, since they must receive their respective acts of to be which are not intrinsic to their substances, if they are to exist at all. This substance which does not limit its act of to be and whose existence must be inferred is therefore not only a being existing in itself (ens per se), but it is also a Being that exists of itself (Ens a Se). This however is not necessarily a note of substance as such. Its demand for existence in itself may be met either by caused or uncaused being. Its substantiality as such does not include the question of the source of existence in itself. Every substance requires that it exist in itself. Only Infinite Substance also exists of itself; that is, only the Infinite Substance is necessarily Self-Existing. What makes all this clear and permits a sound doctrine of substance which involves no such error as the pantheism of Spinoza is the understanding of the real distinction of essence and act of being in all beings of our experience, that is, their participated character. It is this principle which permits Thomism to anticipate and refute the error of the substantialistic pantheism of Spinoza, in whose philosophy no such insight into the true nature of being is possible.”[134]  

 

Leibniz on Substance. Leibniz mistakenly defined substance as an “independent power of action,” thus confusing substance with one of its properties and, consequently, reducing substance into an accident. Leibnizian substance would essentially consist in a simple and unextended active force without a subject of action, called a monad. This monad’s essence would consist in the power of resistance (or impenetrability), which is merely an active tendency having an immanent effect; consequently, there would be no possibility of transitive action between unit monads.   

 

Locke on Substance. The empiricists essentially reduce knowing to the level of sense knowledge and doing so cut off one’s access to substance (substance either becomes that “unknown substrate” or is simply negated as a metaphysical illusion). The empiricist John Locke held that, though substance does exist, we could never know anything about the reality of substance except that it is the substrate or support of the accidents. In reality, substance would be, for him, that “unknown substrate” supporting the accidents. He writes: “If anyone will examine himself concerning this notion of substance in general, he will find that he has no other idea of it at all, but only a supposition of he knows what support of such qualities which are capable of producing simple ideas in us; which qualities are commonly called accidents.”[135] As conceived by the mind, substance, for Locke, would be a “complex idea,” a combination of simple ideas which represent distinct particular things subsisting by themselves. How are the ideas of substances conjured up by the “mind,” which in this case, would mean, for Locke, the imagination? Locke replies: “The mind being furnished with a great number of the simple ideas conveyed in by the senses, as they are found in exterior things, or by reflection on its own operations, takes notice also, that a certain number of these simple ideas go constantly together; which being presumed to belong to one thing, and words being suited to common apprehensions, and made use of for quick dispatch, are called, so united in one subject, by one name; which, by inadvertency, we are apt afterward to talk of and consider as one simple idea, which indeed is a complication of many ideas together: because, as I have said, not imagining how these simple ideas can subsist by themselves, we accustom ourselves to suppose some substratum wherein they do subsist, and from which they do result, which therefore we call substance.”[136] In keeping with his empiricist phenomenalism, Locke teaches that the substance of a cat or dog or rat, to give examples, is merely a collection of a number of simple ideas of sensible qualities which we utilize to give unity to that which we call cat or dog or rat. The result of the imagination’s combination of these simple ideas (which really should be called sense impressions) into “substance” is Locke’s “complex idea.” 

 

Hume on Substance. The radical sensist empiricism of David Hume led him to disregard substance altogether; he claimed that there was no need for the idea of a real support of mental phenomena, i.e., of ideas or states of consciousness. “Substance,” whether material or spiritual, is merely a name (a term, a word) we give for a collection of actions without any subject of these actions. He writes in his A Treatise of Human Nature that “the idea (sense impression) of substance as well as that of a mode, is nothing but a collection of simple ideas (sense impressions) that are united by the imagination and have a peculiar name assigned to them by which we are able to recall either to ourselves, or to others, that collection.”[137] Hume maintained that the idea of substance was nothing but a metaphysical fiction created by the imagination and ought really to be dismissed or abandoned.   

 

Kant on Substance. Kant made substance not anymore a real individual being, a real support of the accidents which inhere in their real subject, but rather an a priori subjective category of the mind, as the principle which unites phenomena in the mind. “Substance,” for Kant, would be one of the twelve a priori categories of the human mind, endowed with innate organizing principles of understanding. The Kantian category of substance, like the other categories of the mind, are imposed upon the organized sense data (sense stimuli coming from the noumenal world being initally molded by the two a priori forms of sensibility, namely, space and time, which are purely subjective) for further and ultimate organization of the initially molded data. When imposed upon the intuitions of sensibility, the category substance gives the effect of persistence of any object that we see in time, as well as the effect of permanence and stability for subjects of passing sensations or phenomena. Do substances exist in extra-mental reality, as is the position of realism? Kant answer is that, though the noumenal world really exists, we do not know anything about it; therefore, he maintains that we do not know if substances really exist in noumenal reality (as is the realist claim), for the “substance” we utilize in thinking is merely a subjective categorical imposition upon initally molded sense data in order to endow this sense data with the characteristic of persistence, permanence and stability.            

 

The error of Kant regarding substance is ultimately traced to his transcendental idealist epistemology, which does great violence to the certainties of common sense and is the great adversary of methodical realism and realist metaphysics. The task of refuting this type of idealism, however, belongs to the philosophical science of gnoseology (also called philosophy of knowledge or epistemology), and therefore, we shall pass on to deal with the nature of accidents. 

 

Accidents

 

An accident is defined as that reality to whose essence it is proper to be in something else, as in its subject. If what is most characteristic of the substance is to be by itself and not in another, that which is most characteristic of accidents is to be in another, that is, to be in the substance. Take for example a cat. The substance here would be the substance cat, while its accidents would be the various perfections inhering in the substance cat (a substance that, though modified by its accidents, nevertheless remains in essence or nature unchanged), accidents such as its shape, size, colour, fluffiness of its fur, etc.  

 

It is to be observed that the definition of accident includes the subject. The nature of the accident is to demand inherence in another. As the substance has a nature or essence to which subsistence is fitting, and which situates the subject within a determinate species, accidents also have their own essence by which they are differentiated from each other, and to which dependence on the being of their subjects is fitting. The essences of accidents are naturally imperfect for they demand the support of their subjects.[138] Rather than simply being, an accident is said to be something belonging to being.[139] Accidents cannot be said to “become” or be corrupted; rather it is the subject that becomes through the accidents.[140] It is for this reason that an accident cannot be defined without the subject as a quasi-part of the definition.[141] “No matter how we take an accident, its very notion implies dependence on a subject but in different ways. For if we take an accident in the abstract, it implies relation to a subject, which relation begins in the accident and terminates in the subject: for whiteness is that whereby a thing is white. Accordingly, in defining an accident in the abstract, we do not put the subject as though it were the first part of the definition, viz., the genus; but we give it the second place which is that of the difference: thus we say snubnosedness is a curvature of the nose. But if we take accidents in the concrete, the relation begins in the subject and terminates at the accident: for a white thing is something that has whiteness. Accordingly, in defining this kind of accident, we place the subject as the genus, which is the first part of the definition; for we say that a snubnose is a curved nose.”[142]

 

Descartes’ Erroneous View of Accidents

 

As we have already seen, Descartes made what was merely accidental, namely, thought and quantity, into substances, thereby mistakenly ‘substantializing’ them. Thought, for him, is immaterial substance, while quantity was material substance, yet illogically, his definition of substance would only apply to God.

 

Descartes negated, in fact, the real distinction between substance and accidents. In keeping with his rationalistic mechanism, he denied that there were absolute accidents in a substance, really distinct from that substance (like extension, qualities and action, that confer upon a subject a real perfection), and sustained only relative accidents determining the substance (that is, accidents that have their being in a subject only because of the bearing which a certain thing has to another; in short, he explained all other accidents, as, for example, the absolute modal accident position, as relations). 

 

The denial of absolute accidents in favor of merely relative ‘determining’ accidents is, of course, erroneous as it goes counter, for example, to our internal experience and real capacity for knowledge, as Bittle explains: “Certainly, many accidents are merely relative; for instance, those of ‘similarity’ and ‘equality’ between two individual substances. The mere fact that two persons or trees are five feet and ten inches tall, does not give to either of them any positive and new perfection or entity beyond what they already possess; their ‘equality’ in height consists entirely in this ‘point of comparison’ or relation. The same applies to the ‘similarity’ between a horse and a cat, because they resemble each other in this that both are ‘white’ in color. But not all accidents are of this kind. There are absolute accidents. In proving this statement, we will restrict ourselves to facts revealed by our own internal experience, because no philosopher can doubt this evidence without destroying the ultimate possibility of all valid knowledge. Our internal experience testifies to us that there are various modifications within us, like thinking, willing, seeing, hearing, feeling, walking, working, and various kinds of productive activity. To deny these activities is to make an illusion of our internal experience as a source of knowledge. These activities are a reality, distinct from our fundamental essence or substance. They are present for a time and then disappear; we exert ourselves to increase or decrease their intensity; we are actively engaged in bringing them forth or stopping them. These activities confer a new perfection and entity upon us which was not there before. Would anyone assert seriously that a blind and deaf person does not lack something which one who sees and hears possesses through the activity of sight and hearing? Or, that a healthy person does not possess a perfection and entity which a critically ill person has lost? If so, then there is no real distinction between blindness and sight, deafness and hearing, health and illness; but that is obviously false. However, while these activities come and go, we still retain our essential identity as an abiding and permanent reality throughout the origin and passing of these transient modifications. But this proves that we are a substance, while these acts are a positive perfection and entity consisting in something more than the mere relation of one thing to another; more, for instance, than the relation of ‘similarity’ between the light of an electric lamp and the light of a star. Knowledge, too, is more than an accidental relation. If it were nothing real supperadded as an entity to the mind, then the mind with knowledge would not be really different from the mind without knowledge. Ignorance and knowledge would really amount to the same thing for a mind. But the mind undergoes a change, when it passes from a state of ignorance to a state of knowledge, as our consciousness clearly testifies. Change, however, implies that something is actually acquired (or lost) in the process. Reversely, when we forget or are victims of amnesia, we realize that we have lost something definite in the line of a perfection for our mind; not the mind itself, of course, because that we still possess, but something that the mind had and now is deprived of. If knowledge were not a real perfection, we would acquire nothing when we learn, and we would lose nothing when we forget; there would then be no real distinction between the erudition of a great thinker and the vacuity of an idiot. Hence, knowledge is something that can be acquired and lost, an accident that is a reality distinct from the mind. The effort we put forth in order to learn proves the same thing. It takes no effort on our part to be similar to another in the color of our complexion or equal to another in our size. But to acquire a knowledge similar or equal to that possessed by another, demands distinct effort and labor. And this proves that knowledge is more than a mere relation or relative accident; it is an absolute accident.”[143]        

 

Threefold Relation Between Substance and Accidents

 

There is a three-fold relation between substance and accidents[144]: 1. The substance is the substratum or the subject of the accidents, the “subject” here the bearer and that which underlies, and it indicates the metaphysical dependence of all the accidents on the substance. The substance is also the substratum of the accidents inasmuch as it gives them the act of being (esse); 2. The substance is to accident what potency is to act, because the accidents perfect the substance. The substance has a potency or passive capacity to receive further perfections conferred to it by its accidents, called accidental forms. For example, the operations of acts of free will are accidents which are a kind of perfection to which a substance is in potency; and 3. The substance is related to the accident as cause is to effect. The substance is the cause of the accidents which arise from it and the accidents come into being because of the substance.

 

The Real Distinction Between Substance and Accidents

 

There is a real distinction between a substance and its accidents, as is seen when observing accidental changes. Observing such accidental changes in the substance, we find that certain secondary perfections disappear and give rise to new ones without a substantial change in the subject. And such accidental alterations can only be possible if these accidents are really distinct from the substance they affect. All the nine accidents are, by their very essences, distinct from their subject. The substance is really distinct from the accidents, being superior to them, for it is the substance that determines the very content of things, making them to be what they are, whereas the accidents must depend entirely upon the substance, their substratum, for their very being.

 

The Act of Being Properly Belongs to the Substance

 

The act of being (esse) properly belongs to the subject of the accidents which is the substance. Accidents also are, but are by reason of the act of being that belongs to the substance. It is only the substance that is in the proper sense of the term. To say that accidents have an act of being of their own, as Suarez did, would undermine the unity of the substance-accidents composite (that is one substance and one substance only having its own accidents). We should also be reminded that the substance is being (ens) in the strict sense. Accidents are only by reason of being supported by its substratum or support which is the substance. Thus, it is only the substance that should properly be called being; accidents instead are something belonging to a being (ens).   

 

The Unity of the Substance-Accidents Composite

 

Accidents depend entirely on the substance for their being, for they do not have esse of their own but are because of the act of being of the substance. The real distinction between substance and accidents and their inequality do not in any way undermine the radical unity of the substance-accident composite of  being (ens). The real distinction cannot destroy the unity of ens for a substance and its accidents are not many beings mixed up together to form a whole; rather, there is only one being in the strict sense, which is the substance, and all of the accidents of this particular substance “belong to it,” receiving their very being from the substance without which they would cease to exist. Accidents cannot be autonomous realities separated from substance; they are rather the determining aspects of a substance, perfecting and completing it.

 

Knowledge of  Substance and Accidents

 

We arrive at a knowledge of the substance-accidents composite by means of our intellect, initially through the information provided it by our senses. Our senses are only able to directly grasp the accidents of things, and this data is passed over to the intellect which arrives at its source and basis, which is the substance, again by means of the accidents. It is only the intellect that is capable of grasping the nature of the thing, its essence. In the process of knowing a thing composed of substance and accidents we employ a constant going back and forth from accidents to substance and from substance back to the accidents: 1. In the beginning we have a vague knowledge of the composite of substance and accidents. When we are in the forest for example and see a large being approaching at a distance, its nature unknown to us, we know that the various qualities perceived by our senses, for example, the colour, size and shape, of the being, are not independent realities existing in themselves but rather belong to a single substance, the being approaching at a distance. Even at this initial stage of the knowledge process we already perceive that the various accidents are but secondary manifestations belonging to a single individual substance that subsists by itself, even though we are unable as yet to determine the exact nature or essence of this substance. It should be recalled that being (ens) is the first thing that is grasped by the intellect, and since substance is being in the strict sense, we cannot perceive accidents without at the same time perceiving the subject or substance in which these accidents inhere in; 2. From the perception of the accidents by the senses we move now to a knowledge of the nature of the substance. The accidents do not hide the substance; rather, they reveal it. The accidents of the bear approaching at a distance, reveal the nature or essence of the bear. Thus, through external manifestations we arrive at a knowledge of the substantial core of the subject in question; 3. Then, from the substance we go back to the accidents. Having arrived at a knowledge of the nature of the thing perceived, in this case, our approaching bear, this new knowledge gives us much more insight into the other accidents of the animal in question as well as their mutual relationships. Knowing the essence or nature of bears, man knows that bears can at times, when provoked, or when protecting their young in the vicinity, attack humans in a ferocious manner, and thus he adjusts his behaviour accordingly with the situation.      

 

Concerning our knowledge of substance, Llano explains that “substance is being that is by itself (per se): it is what is properly called being. Substance is what has the act of being and what subsists by its own act of being. Accidents, in contrast, are not beings in themselves, they are beings of a being (entis entia) or – as Aristotle says – ‘buds and concomitances of beings’[145]; they inhere in substance and participate in its act of being.

 

“In natural reality substance and accidents form a composite unity: the concrete and singular being. Substance is never given without accidents, since it always subsists accidentally determined; and accidents are never given without substance since, of themselves, they do not have an act of being.

 

“The dichotomies which the rationalist mode of thought leads to, tend to isolate substance from accidents. But it is an error to think that substance can only be known if it is separated from accidents: thus conceived substance immediately becomes unknowable, because such a separation can never occur. These rationalist oppositions lead to understanding accident as that which is known by the senses and substance as that which is known by thought.[146]

 

“What really happens is that the knowledge of the reality of substance is not separable from the experience of the real whole, of being which is known by the senses and by the intellect, and which includes both substance and accidents, because it is an unum composed of both principles. The substance of material things is not directly knowable by the senses, but the intellect knows it immediately through the sense data in which substance appears. Substance – that which is by itself – cannot be reduced to that which is offered directly by sense experience, but it is discovered within the latter.

 

The knowledge of substance begins with its accidents, which make it known because they participate in the being (esse) of the substance. The accidents do not hide the substance, as if they were a sort of opaque crust covering it (this crude imaginative representation of the theory is at the root of not a few unjustified criticisms). The knowledge of the accidents, rather, entails a certain knowledge of the substance because any accident is known as an intrinsic reference to substance, which the intellect grasps confusedly but immediately in any accidental determination. For example, when I know the color white, what I grasp is not an isolated and subsisting ‘whiteness,’ but rather ‘this white thing,’ be it chalk, paper, light or whatever. Whence – as analytic philosophy has demonstrated – things cannot be counted numerically in adjectival terms, but only in terms of substances.[147]

 

“At first, substance is known above all as the substrate of the accidents, of the properties and the changes in things. But this approach – as Aristotle has lucidly demonstrated[148] – is insufficient. Subsequently, substance is known as the essence of the thing, as that which each being is in itself, as an act from which properties flow. Finally, the real constitutive factor of substance is attained: subsistence. Substance is what is determinate and separate,[149] what has being (esse) in itself, the subject of the act of being.”[150]


 

 

CHAPTER 4

 

THE CATEGORIES

 

 

The categories[151] (also called the predicaments), are the supreme modes of being, divided into substantial being and accidental being. The supreme genera of the categories are composed of the substance and the nine accidents, namely: quantity, quality, relation, action, passion, time (when?), place (where?), position (situs), and possession (habitus). Some brief examples of each of the ten categories will be very helpful in gaining a knowledge of these supreme classes of being which, though like being cannot be strictly defined, can rather be described and illustrated with examples. Here are the following examples: “James is a man” (substance); “James weighs 200 pounds” (quantity); “James is intelligent” (quality); “James is the son of Joe” (relation); “James is pushing the chair” (action); “James is being mugged” (passion); “James arrived at his house at seven in the evening” (time or when?); “James is in Los Angeles” (place or where?); “James is sitting down” (position or situs); “James is wearing a formal suit and tie” (possession or habitus). It should be noted that accidents have essences of their own (essence here is understood in the broad sense as referring to both the nature of substances and accidents). 

 

A Schematic Presentation of the Nine Accidents

 

The Stagirite arrived at his list of nine accidents by empirical test, while the Aquinate derived the list of accidents upon a more systematic basis, according to their intrinsic, or extrinsic, or partly intrinsic and extrinsic determination of the subject (the substance). We find this procedure outlined in Aquinas’ Commentary on the Metaphysics: “A predicate can be referred to a subject in three ways. This occurs in one way when the predicate states what the subject is, as when I say that Socrates is an animal; for Socrates is the thing which is an animal. And this predicate is said to signify first substance, i.e. a particular substance, of which all attributes are predicated.

 

“A predicate is referred to a subject in a second way when the predicate is taken as being in the subject, and this predicate is in the subject either essentially and absolutely and as something flowing from its matter, and then it is quantity; or as something flowing from its form, and then it is quality; or it is not present in the subject absolutely but with reference to something else, and then it is relation.

 

“A predicate is referred to a subject in a third way when the predicate is taken from something extrinsic to the subject, and this occurs in two ways. In one way, that from which the predicate is taken is totally extrinsic to the subject; and if this is not a measure of the subject, it is predicated after the manner of attire (possession), as when it is said that Socrates is shod or clothed. But if it is a measure of the subject, then, since an extrinsic measure is either time or place, the predicament is taken either in reference to time, and so it will be when; or if it is taken in reference to place and the order of parts in place is not considered, it will be where; but if this order is considered, it will be position.   

 

“In another way, that from which the predicate is taken, though outside the subject, is nevertheless from a certain point of view in the subject of which it is predicated. And if it is from the viewpoint of the principle, then it is predicated as an action; for the principle of action is in the subject. But if it is from the viewpoint of its terminus, then it will be predicated as a passion; for a passion is terminated in the subject which is being acted upon.”[152]

 

It should be noted that the list of accidents in its totality applies only to material substances. Only the material substance is quantified. Immaterial beings are not quantified. Only the corporeal substance (strictly speaking, only one kind of it, namely, man) can have external possessions (this pertains to the accident habitus), and only the material substance is subject to the conditions of space and time, as well as to the circumstances of transeunt action. This is why most of the predicamental accidents, namely, quantity, possession (habitus), position (posture), time, place, action and passion are given extensive treatment in cosmology (also called the philosophy of nature, or more specifically, the philosophy of inanimate nature), while metaphysics gives extensive treatment to the accidents quality and relation since these accidents are to be found not just in material beings but also in the immaterial realm (though angels certainly have accidents, note, however, that God, being Pure Act of Being, having no potentiality whatsoever, has no accidents).  

 

We can sum up Aquinas’ presentation of the nine accidents as follows: As regards the predicament which refers to that which is the subject we have substance. As regards the predicament which refers to that which is in the subject per se and absolutely following upon the matter, we have quantity. As regards the predicament which refers to that which is in the subject per se and absolutely following upon the form, we have quality. As regards the predicament which refers to that which is in the subject not absolutely, we have relation. As regards the predicament which refers to that which is outside the subject yet some way in it as principle we have action; in it as a terminus and we have passion. As regards the predicament which refers to that which is entirely outside the subject and not a measure of it, we have possession (habitus); or as a measure of it as to time we have when; as to place but not its parts we have where; as to place and its parts we have position (posture).

 

1. Quantity       

 

Quantity is derived from the Latin word quantum, an interrogative word meaning “how much?” When one poses the question “how much” one is asking about quantity. Quantity involves the notion of amount, extent, bulk, size, content, parts and number. Examples of quantity include weight and size. It asks, in terms of measurement, how big or little, and how much. Here are some examples of indications of quantity: “The building is a thousand feet tall”; “The truck weighs fifteen tons”; “The jar contains ten pebbles.” “The map is eight by eleven.” All these predicates indicate various quantities.

 

Quantity is not to be identified with the substance; rather, quantity is an accident, an accident pertaining to everything corporeal. All material beings have a definite quantity, and this arises from the determinable element in the hylemorphic composite, namely the matter. Properly speaking, quantity pertains to bodily substances. Immaterial beings like angels do not have quantity. However, by an extension of meaning quantity may be applied to material things which are not substances, and by analogy, we are able to apply it even to non-material or spiritual substances and accidents. Thus, we may speak of the quantity of time, the amount of fortitude in a person, and the number of angels. Here we are speaking of non-literal applications of quantity.  But strictly and properly speaking, quantity refers to corporeal quantity, bodily quantity, mensurable quantity, the material substance which has dimensions. In its literal meaning quantity is a proper accident only of the bodily substance.

 

We look at the interior of an aquarium; we see many beings presently there like various types of fish, rocks, and pebbles. All these objects have their respective places in the aquarium. We also observe that these various objects are extended, filling their respective places, being “part here and part there.” Now external quantity is the the property which extends a bodily substance so that it is “part here, part there,” and is defined as the property whereby a bodily substance has parts outside of parts, with reference to its place.

 

However, external quantity (also called extrinsic extension or local quantity, actuated, in the “second act,” by which the parts are distinguished with regard to place so that one part is not in the place in which there is another part) is not the essence of quantity itself but rather the complement and external manifestation of the inner, essential thing called internal quantity, which is quantity in the strict sense, and is defined as the property whereby an existing body has actual parts in itself. This type of quantity is also called intrinsic extension or exigential quantity or the demand for quantity, “in the first act,” by which parts are distinguished among themselves so that one part is not the other. Let us take for example the rock in the aquarium. We observe that that rock could not spread itself out to fill its place (that is, could not have actual external quantity or local quantity) if it did not possess some inner aptitude for such an extension. In short, that rock must have parts in itself (that is, it must be internally quantified) if it has parts in a place (or is externally quantified). The inner extension or internal quantity of our rock consists in “the position of parts outside parts in the substance.” This type of quantity, internal quantity, is quantity in the strict sense and is the property whereby an existing bodily substance has, in itself, parts outside of parts. On internal quantity (intrinsic extension) as constituting the essence of quantity, Varvello writes: “That which constitutes the essence of anything is the entity which we first conceive of that thing when we think of it, and besides we conceive it as the root of all the other properties of the same thing. Now the entity which we first conceive when we think of the quantity of a body, is what we call intrinsic extension, or the distinction of the parts in regard to themselves, in such a way that one part is not another; and the other properties of a body we conceive as following intrinsic extension. For the reason why we know that a body can have distinct parts with regard to another (namely to place) and so be impenetrable, divisible, measurable, is that we understand it to have first parts which are distinct in an absolute sense, that is, with regard to themselves. By granting this property (intrinsic extension) to a body, we know that the others too can be granted; but if we deny this property, we know that the others also should be denied, and so this property, intrinsic extension, and not the others, constitutes the essence of quantity.”[153]   

 

Hart observes that followers of St. Thomas, like Sylvester of Ferrara and John of St. Thomas, working upon texts of the Angelic Doctor, in particular, texts like Summa Theologiae, I, q. 50, a. 2, Summa Theologiae, III, q. 76, a. 3, Summa Contra Gentiles, IV, chapter 65, and In IV Sent., d. 10, q. 1, a. 3, ad 2, hold that “the material substance possesses simply its prime matter and substantial form which has of itself no actual integral parts. It is thus not divisible into smaller portions, each of which would contain the two essential principles. It has of itself a need for integral parts, a capability for receiving them in view of its material principle. This makes a material substance quite different from a spiritual substance, which has no such limiting demand. The quantity confers an internal distinction of integral parts, one outside the other within the whole, that is, an internal or potential quantity, as an absolute accident inseparable from the substance itself. This is the primary effect of quantity, its essence as such. The secondary effects which follow from its essence naturally are occupation of space and therewith actual local extension, quantitative divisibility, measurability, and impenetrability (that is, one part cannot occupy the same place in space as another). This actual local extension is therefore a separate additional character but is not absolutely required for quantity as such.”[154]

 

Hart then writes that this position is obviously “in harmony with the theology of the Eucharist. The substance of Christ’s Body has the perfection of essential quantity, that is, internal or potential quantity, with parts of the Body distinct with reference to the whole. But the secondary effects of actual local extension with its divisibility, measurability, and impenetrability are prevented. The Body is therefore whole in the entire Host and whole in every part of the Host.”[155]

 

Four Properties of Bodies as Quantified. As we have seen, internal quantity (internal or intrinsic extension) is the essential constituent of quantity itself. But what are the properties of bodies as quantified, those characteristics which belong by natural necessity to quantified matter? They are four, namely, 1. external extension (or extrinsic extension) which is the property of natural bodies by which they are extended in space and occupy place; 2. incompenetrability (or impenetrability), that property of a natural body, consequent upon its external extension, which prevents another body from occupying its place while it is present there itself; 3. divisibility, that property of a natural body, consequent upon its extension, which renders it capable of being “taken apart” or divided into an indefinite number of parts; and 4. mensurability, which is that property of a natural body, consequent upon its external extension, which renders it capable of comparison with the extension of other bodies, and so discerned as greater, or lesser, or equal. Mensurability also renders a body capable of being comparatively numbered in the extent of its divisible parts.    

 

Continuous Quantity and Discrete Quantity. Quantity is either continuous or discrete.[156] Continuous quantity is unbroken, undivided quantity and a bodily substance which has continuous quantity is called a continuum. A continuum is either perfect or imperfect. A perfect continuum has no pores or vacuoles or interstices between or among its parts. An example of a perfect continuum would be a solid piece of hard rock. An imperfect continuum, on the other hand, has pores, interstices or intervals, but its own unbroken substance completely surrounds them. An example of an imperfect continuum would be the same hard piece of rock with many holes drilled through it.

 

Discrete quantity is non-continuous quantity, broken or divided quantity. A pebble on a table is a continuum while five separate pebbles lying on that same table, considered as one quantity or amount, is a discrete quantity. If the five pebbles are close enough to come into immediate contact with one another, then the quantity is contiguous. If not, if the pebbles are not in immediate contact with each other, then the quantity is non-contiguous or separate. The five pebbles held closely together in the palm of my hand is called a contiguum. The pebbles held loosely in my open hand so that the pebbles do not touch one another is termed a discrete separate quantity.  

 

Quantity is Potentially, Not Actually, Infinite. Actually infinite quantity is repugnant for “1. All quantity, whether continuous or separated, is made up of parts which, being parts, are finite. But it is absurd that the infinite in act should be obtained through a multiplication of finites, just as it is equally absurd that the unlimited be obtained through the multiplication of limits ; 2. Quantity which is supposed to be actually infinite, should be made up of parts. Now take away from this quantity one part. The part which remains will be either finite or infinite. If finite, we must say that the infinite can be diminished. If infinite, we must say that we can have an infinite greater than another infinite. But both hypotheses are absurd; and 3. Quantity which is supposed to be actually infinite, since it is made up of parts, can be divided into two, three, four parts, etc. Now these parts will be either finite, or infinite. If finite, the absurdity follows that from the multiplication of finites the infinite can be obtained. If infinite two other absurd conclusions follow: a) the whole is not greater than its single parts, because these also are supposed to be infinite; b) there can be an infinite greater than other infinities, because four parts are surely greater than three parts, three greater than two, therefore an actually infinite quantity is repugnant.”[157]   

 

Quantity is Not Identified with Substance. Though Descartes admitted to a modal distinction between substance and accidents (i.e., that some accidents affect substance variably), nevertheless, he erroneously maintained that the nature of a physical body was extension in three dimensions, thus identifying substance with extension. He identified the bodily substance with quantity on the ground that there was no clear and distinct idea of corporeal substance apart from extension.[158] But contrary to Descartes’ mechanism, quantity is an accident, a property of  corporeal substance, and is not to be identified with it. Quantity is something which a bodily substance has, not something which a bodily substance is: “Extension manifests itself as a different nature in reality from the substance of the extended thing. The extension or size can change, while its subject retains substantial identity. The animal remains the same animal as it grows from foal to horse. It undergoes real change in size, but remains really the same in substantial nature. The substantial nature, moreover, is found whole and entire in every part of its extension. Every part of a man’s body is human, every part of the iron is equally metal. Its extension, on the other hand, is not found whole and entire in each part. Rather, one part is not found in another, but outside the other. Every part of the human body will possess the same substantial nature as any other part, but not the same extension. The parts really coincide in nature substantially; but they do not coincide in their extension, for each part really lies outside the others. The substance, then, is really different from each part and so from the totality of the parts that constitute the thing’s extension or quantity. These two facts, namely growth in plants and animals, and identity of nature throughout really differing parts, establish sufficiently the real difference between substance and quantity.

 

“A corporeal nature just in itself, therefore, is not extended. But it is a nature that is capable of extension in the three dimensions. The capability or potency to extension belongs to its very essence, and distinguishes it radically from supersensible substance. A material nature is necessarily composed of the two physical principles, matter and form. The matter allows the formal principle to be spread through parts outside parts without any formal increase whatsoever. In this way it renders the nature itself potentially extended. But that potentiality can be actuated only through an accident, the accident of quantity. Not even prime matter, just in itself, is extended. Prime matter is only the substantial basis of extension, insofar as it makes a formally identical nature capable of spread by a spperadded accident through parts outside parts. The parts may be homogeneous, as in the case of a metal like iron, or heterogeneous as in animals where the same animal nature is spread through bone, marrow, muscle, nerves, and other such dissimilar parts.

 

“Continuous quantity, then, is an accident of corporeal nature, and not a substance. It is not primarily what exists, but is only an accidental mode under which corporeal substances exist. Still less does discrete quantity exhibit itself as the substance of anything. It rather presupposes extended substances and enumerates them. It is accordingly subsequent to continuous quantity, and so is even more manifestly of the accidental order.”[159]       

 

2. Quality

 

The accident quality intrinsically affects the substance in itself, making it to be in one way or another. It arises from the form of things and is found in both corporeal and incorporeal beings. It is the most inclusive of accidents, having the widest scope, meaning, and application. Quality indicates what sort or kind a thing is. It modifies or influences a substance in itself or in its activities. In language, most adjectives express qualities. It makes the substance which it affects either better or worse, or makes it function more easily or less easily. Qualities have their opposites and can be listed in opposite pairs, like knowledge and ignorance, virtue and vice, and health and illness. They are also susceptible to degrees, capable of being increased or diminished in intensity.

 

Kinds of Qualities. Qualities are reduced to the following four groups, namely, alterable qualities, shape and figure, operative powers or faculties, and habits: a) Alterable Qualities (also called passive qualities or characteristics). These qualities affect a physical change in a substance. Alterable qualities include temperature, color and humidity. The rise in temperature of water from cold to hot, for example, affects the water physically ; b) Shape and Figure. These qualities of corporeal bodies define the limits of quantity, giving it definite dimensions and contours ; c) Operative Powers. These qualities are also called operative faculties or potencies. They are qualities which enable the subject to carry out certain acts like thinking, willing, walking, etc. They include, for example, the intelligence and will in man, and the power of locomotion in both man and animal ; d) Habits. These are stable qualities by which a subject is either well or ill-disposed with regard to a certain perfection befitting its nature (entitative habits) or its action or goal (operative habits). Habits are divided into entitative habits (like the habits of health or sickness) and operative habits (like virtues or vices).

 

3. Relation

 

Relation[160] is that accident whose nature is a reference or order of one substance towards another. It is that reference of one being towards another being, the order that a being has with respect to other beings distinct from it. Examples of relations include paternity, sonship and filiation. Paternity, for example, is the accident that links father to son. Although it is based on the fact that the father gave life to his son, paternity is itself no more than a mere relation or reference which does not intrinsically add a new characteristic or property to the father’s substance.

 

Main Division of Relations: Logical Relations and Real Relations. Relations can either be real relations or relations of reason (logical relations). For example, the relation between subject and predicate in a proposition is a logical relation. Real relations, on the other hand, refer to relations in extra-mental reality.

 

The elements of a real relation are the following: 1. the subject, which is the person or thing in which the relation resides; 2. the term (terminus), to which the subject is related; 3. the basis of the order between the subject and the terminus; and 4. the relation itself, or the bond linking one thing to another. In the case of sonship, for example, the subject is the son, the terminus will be the father and mother (parents), the basis would be generation (what causes the son to be related to his parents is their having begotten him), and the relation itself would be sonship.    

 

Five Conditions for a Real Relation. There are five conditions for a relation to be real, namely, a real subject, a real foundation or basis, a real term, a real distinction between subject and term, and lastly, things related as subject and term must be in the same order or else the relation will not be real in the subject and term: “(1) On the part of the subject related, the subject is real. Paternity is a real relation because the father is a real subject. (2) The foundation of the relation is real. Thus the father generating is the real foundation for paternity. (3) The term of the relation is real. The offspring as the term of the relation of paternity is real. (4) The term must be really distinct from the subject of the relation. When the subject is related to itself, the relation is logical such as the relation between Peter and the man called Peter. (5) The things related as subject and term must be in the same order, otherwise the relation is not real in subject and term. For example, the relation of hearing is not in the same order in respect to subject and term. For the subject hears the sound but the sound does not hear the subject. This relation of hearing is real on the part of the subject hearing. So too creatures and the Creator are really related on the part of creatures. Creatures depend on the Creator to be and to act. But the relation of Creator and creature is not real because God cannot be the real recipient of the categorical relation because He does not stand in potency to anything as Pure Act.”[161]  

 

Kant’s Denial of Real Relations and Mercier’s Refutation. True to his transcendental idealism, Immanuel Kant maintained that relation was but an a priori subjective category of the mind, not an extra-subjective really existing accidental category or predicament. Contrary to this position Mercier defends the existence of real relations and critiques the Kantian position: “The proof that real relations exist lies in the fact that, whether we think or not, two real things which each measure a yard in length are equal, that a relation of equality exists between them; that two twin-brothers are really alike, apart from what anybody thinks. Hence in nature itself there do exist real relations. The universe is made up of individual beings that are not entirely absolute but which are interconnected with one another, long before we have any knowledge of them, by a number of relations that constitute the order of the universe.   

 

“Opposed to this theory of relation stands Kant’s idealistic conception of relation as a subjective category of the mind which appertains to phenomena only as the mind introduces it into them. The argument he uses to support this view is that without a subjective operation of the understanding we can never perceive a relation, there can be no relation for us; or, in other words, because we are never aware of a relation except by a mental action, therefore it must be that the mind introduces into phenomena the relations and laws which govern them. This argument, however, sins through being ambiguous and is besides erroneous. In the first place, whilst it may be true that a relation does not ‘exist for us,’ that we do not know it as long as we fail to apprehend its two terms and to perceive its foundation, nevertheless there are relations the terms and foundation of which are anterior to any thought and in consequence are not due to the mind. In the second place, besides all the arguments that militate against idealism in general, we may urge against this idealistic theory of relation a special difficulty. Every relation considered a priori, without application to anything real, is capable of being either affirmative or negative. How then does it happen that in certain particular cases we adhere to one of such alternatives  instead of to the other? What, for instance, makes us judge that two particular phenomena are alike rather than not alike? Even if the faculty of judging likeness and difference is an internal law of the mind, the particular applications of such a generic faculty can only come from external things themselves. And if this is so, it must be allowed that some relations have a real, objective foundation that is independent of our minds and of its modes of knowing.”[162]

 

4. Action

 

Action arises in the substance insofar as it is the efficient or agent principle of change or motion in something. This predicamental accident is the producing of an effect by an agent and  is indicated when we say, for example, that: “The dog is gnawing a bone”; “The waiter is pushing the refrigerator”; “The electrician is cleaning the airconditioner”; “The soccer player is kicking the ball.”      

 

5. Passion

 

Passion involves the receiving or enduring or undergoing of change. It indicates that something is affected and thus, it is the correlative and complement of action. It is the reception of the effect from another, in the sense of suffering, bearing, enduring, receiving, and being acted on. In passion a being actually receives an action, the actual undergoing of action in its effect. If action is the actual doing, passion, the complement of action, is the actual undergoing. Passion is the opposite of action, but it is a related opposite, an opposite which is a term or goal. Action and passion correspond mutually to each other, a motion[163] with an origin in the substance acting and a terminus in the substance suffering, enduring or undergoing. In language passion is expressed by the passive voice of the transitive verb. Examples of passion is indicated in the following: “The soldier was shot in the leg”; “Betty endured her ordeal in the mountains after getting lost”; “The boxer was punched in the stomach.” Passion answers the question, “What is happening to it.”  

 

6. When? (Time)

 

Time[164] regards the temporal situation of a corporeal substance or of an event with reference to what precedes and what follows. Time is indicated using such expressions as: “Sam took his exam today”; “Sam has an appointment at five o’clock”; “Sam will go to the restaurant after classes”; “Sam had the accident ten years ago”; “Sam’s father was born in the year 1964.” Though oftentimes used interchangeably, time is not the same as the categorical accident when for the latter signifies existence in time; but time does not exist in time; therefore, when is not time. Our categorical accident when is defined as that accident resulting in a body from the time by which it is measured. When is a determination which a body has from extrinsic time by which it is measured.  

 

Time is a species of duration. Duration is defined as the persistence of a being in existence and can be of three types, namely, eternity (the duration of God’s existence), aeviternity (the duration of created spiritual substances), and time (the duration of physical bodies).

 

Eternity is duration without beginning, succession or ending. This type of duration, strictly speaking, belongs to God alone, the Infinite Being, and is identified with His essence. Boethius defines eternity as “the complete, simultaneous and perfect possession of interminable life.”[165]

 

Aeviternity is a species of duration with a beginning but with no end and is proper to angels and human souls. Though subject to accidental modification (i.e., willing and thinking) these immaterial substances do not undergo substantial change. They have a beginning but have no end; they cannot be destroyed except by annihilation by God. Angels and human souls are substantially incorruptible and immortal and thus their mode of duration is different from the eternity of God. Their mode of duration is called aeviternity (aeviternum or aeviternitas), a sort of intermediate state between eternity and time. The accidental modifications of an immaterial creatural being is surely measured by a type of time, since there is succession involved in these accidental changes, but the time, at least as regards the angels, is discontinuous rather than continuous.  

 

Time, on the other hand, is a species of duration which has a beginning and an end, “an accident (or non-substantial reality) which affects bodily things inasmuch as these have motion or movement which presents to the mind phases of duration, and of before and of afterwards. Aristotle called time ‘the number or enumeration of motion looked at from the standpoint of before and afterwards.’ The ‘number of motion’ means ‘the measure of movements’ or of the concrete items or moments of a continuous thing, in which the end of one moment is the beginning of the next following.”[166] Time is number for it distinguishes the parts of motion, and to distinguish parts is to number them. Time is not what is counted with (abstract or mathematical number) but rather what is counted (concrete number). Time is what is counted, the parts of motion, thus it is concrete number. 

 

Time is defined by Aristotle as “the number of movement according to before and after.”[167] “This definition,” explains Wallace, “develops from three inductive determinations that successively establish (1) time as something of motion, (2) time as continuous, and (3) time as number. (1) Time is not the same thing as motion, for many different motions can take place in the same time, and motions can be fast or slow whereas time remains uniform in its flow. On the other hand, time inevitably accompanies motion, for where there is no awareness of motion or change there is no passage of time. (2) Time is continuous because it is associated with motion that traverses a continuous magnitude. A continuum is formally one but materially made up of parts: these parts, joined to each other by indivisibles, constitute an order of local before and after. A motion that traverses such a spatial continuum has also an order of before and after, as does time’s passage, e.g., when punctuated by the sun’s rising and setting, the moon’s phases, the ebb and flow of the tides, the position of hands on a dial. (3) Time is a numbering of the successive ‘nows’ that serve to mark its passage. To grasp its being one must visualize a before and after under the common aspect of their being a now and count them as two nows, i.e., as a now-before and a now-after. These nows, the correlates of the here-before and there-after in motion, are the numbered terminals of the continuum that itself is time. The numbering referred to here is not that of an absolute or mathematical number divorced from passage. Time is rather numbered number, the number of and in motion that is indissociable from its flux.

 

“It follows from this analysis that time has the same mode of existence as motion; as a flowing continuum, it exists by reason of its indivisible, the present, the punctiform now that separates but links past and future. Time is the measure of motion, and so everything in nature is in time inasmuch as it is connected with motion. Every natural substance, precisely as a mobile being, enjoys an existential duration from generation to corruption that is contained within time.”[168]

 

Time is not a purely mental being, the position, for example, of Descartes (a mode of thought[169]) and Kant (an innate subjective a priori form of sensibility, anterior to all experience, making all things and experiences appear as occurring in time[170]). Neither is time a real existing thing in the physical world independent of the mind as Epicurus and Gassendi, for example, maintain.[171] Rather, time is a conceptual entity with a foundation in reality. Time is a mental being, with a ground, a foundation, in the reality of the movements occurring in nature. And these movements occurring in nature are real and objective, whether our mind is focused on them or not.

 

Real Time, Possible Time, Absolute Time, and Imaginary Time. Time involved in actual movements and changes occurring in the physical world is called real time. Time involved in possible movements and changes which can, but will never, occur is called possible time. The sum of real time and possible time is called absolute time. An image of absolute time fashioned as a sort of receptacle or stream wherein all individual times, actual and possible, have a place, is called imaginary time. 

 

Continuous Time, Discrete Time, Intrinsic Time and Extrinsic Time. Continuous time is the successive duration of uninterrupted motion or movement. Discrete time is divided into corporal discrete time and spiritual discrete time. Corporal discrete time is the duration of interrupted motion or movement, while spiritual discrete time (proper to the angels) is a plurality of spiritual operations (i.e., thinking, willing), each of which has its own indivisible duration, for it is not successive.

 

Intrinsic Time and Extrinsic Time. Time, as measure, is principally divided into intrinsic time and extrinsic time. Intrinsic Time (also called individual time or particular time) is the intrinsic duration of motion or movement as measured, while extrinsic time (also called general time or common time) is the intrinsic duration of any motion or movement that is used to measure the duration of another motion or movement, as, for example, when the motion of a race watch measures the duration of a Formula One race.[172]

    

7. Place (Where?)

 

Place[173] is an accident that regards the localization of the substance, that is, it is the accident which arises in a corporeal substance because of its being here or there. It deals with the position of a body in space, with reference to other bodies. Some examples of propositions referring to place: “Gerard is in New York”; “Gerard is at the street-corner”; “Gerard is at the Chinese restaurant” 

 

Place is defined as the innermost motionless boundary of what contains or the immediate immovable surface (or limit) of that which contains a body.  This is external, proper place, or what is commonly understood by place. First of all we must distinguish between external place and internal place, and between proper place and common place. Internal place is the surface proper to any body, which surface is considered as its receptacle, while external place (which the ordinary man understands when one speaks of place) is the place which a body has from the surface of another or other bodies surrounding it. The external place of a car, for example, would be the surface of the area where the car is located as well as the air which surrounds the car. Now external place is subdivided into proper place and common place. Proper place is the surface of the surrounding body in which the body located or placed is immediately surrounded. The external proper place of the water which fills a water glass would be the internal surface itself of the water glass holding the water. Common place, on the other hand, is the surface of the surrounding body in which many bodies are contained mediately. The external common place of the filled water glass would be the internal surface of the room where the glass is located in.   

 

External proper place is defined as the concave surface of a hollow body, immediately surrounding another body, and conceived as immovable. Varvello explains the parts of this definition for us: “1) ‘The concave surface of a hollow body’ because external place is admitted by all to be in the surface of the body containing another body; but what contains another body must be hollow in order that it may receive that other body in its hollowness ; 2) ‘Immediately surrounding another body,’ because here we treat of the external and proper place of one and the same body; but place of this kind is evidently constituted of the surface which receives into its sides the located body, and which is filled up and measured by the located body ; 3) ‘And conceived as immovable,’ although the surface of the body locating very often is physically, that is, materially moved and changed (as happens with the surface of water and air which surrounds a rock placed in the sea), nevertheless the same surface considered mathematically, that is, formally as a certain surface, is neither moved nor changed, but always retains the same dimensions and the same distances from the other parts of space; that is, for example, from the surface of the shore, from the poles and center of the earth, and therefore it is said to be immovable.”[174]   

 

It should be noted that the categorical accident where (or ubi) is not place. Where is defined as the accident that results from the circumscription of a body by the circumscription of a place. It is the intrinsic determination of a body that results from place, and is therefore a categorical accident of a kind all its own.

 

How may a thing be in a place? How may it be localized? How may something be present? A reality is localized in four chief ways, namely, circumscriptively, informatively, operatively, and sacramentally: “1. If the thing localized is a bodily substance with quantity it has presence in a place, or is localized, in the literal and proper sense of these expressions. A body is in a place (external and proper place) when its own dimensions are immediately circumscribed by the dimensions of the surrounding surface. Just so the baseball of which we are speaking is literally and properly localized by the immediately surrounding air, the exactly-fitting pocket of air, the inner surface of which is co-dimensional with the outer surface of the baseball. Lay a coin on a sheet of paper and, with a finely sharpened pencil, draw a close-fitting circle arround it. You have thus ‘written around’ the coin, and the circle you have written or drawn indicates the location of the coin in so far as it has place on the paper. Now, the Latin circumscriptum means ‘written around.’ This term gives us the English phrase circumscription, or circumscriptive location. Circumscriptive location is what we call location in its literal and proper sense. And we say that all bodily substances are located, or are in their proper external places, circumscriptively. Only bodies can be present in a place circumscriptively. Yet, by a figure of speech, by metaphor or analogy, we use the language of circumscription very frequently when we speak of non-bodily things. Thus we speak of the place of the angels in heaven, and of the places left vacant by the rebel angels. Thus again we speak of man’s knowledge as something that is in him; our language seems to suggest that it is in him in somewhat the same manner as his heart or his liver is in him. But, of course, our language is metaphorical. Non-material things have no dimensions which can be co-dimensional with a containing surface, and hence they cannot literally be in a place circumscriptively.

 

“2. If the thing localized is a form which gives actuality (existence) to a substance or accident, it is said to in-form such substance or accident, and to be in that substance or accident (i.e., to be located or placed there) informatively. Thus the substantial form of any material substance is said to be in that substance, or to be located in that substance, informatively. Thus the soul is said to be located in the body. Thus the character or quality of beauty is said to be in a beautiful face or scene.

 

“3. If the thing localized is a working force, an acting power, it is said to be present where it works in a manner that is called operatively; it is said to be present or to be placed operatively. There are two types of operative presence: (a) A creatural power, a finite power (substantial – like the soul; or accidental – like the power of seeing) can be present only in one subject at a time, and is definitely limited to that subject, and can function only there. It is thus said to be definitively present in the subject in which it operates. Thus the human soul is said to be present in the body operatively and definitively; we have already seen that the soul is in the body informatively. (b) The Infinite Power (that is, the Divine Essence Itself) is unlimited in itself, and therefore is unlimited in the field of its exercise. And so it is present everywhere; it is ubiquitously present (the term is from the Latin ubique, ‘everywhere’). Thus God (and God’s power) is present everywhere operatively and ubiquitously; and, since God’s power is identified with His Essence, his very Being, He is present everywhere in full essence or essentially.

 

“4. The fourth mode of localization or presence (or ubication, as it is sometimes called; a term from the Latin ubicatio or ‘whereness’) does not lie within the proper scope of a purely philosophical discussion, but we add it here for reasons of completeness. It is the mode of presence exampled by Christ in the Holy Eucharist. This mode of presence is called sacramental, and it is defined as a presence wherein a located substance has place through the mediation of the dimensions of another substance, but without making these dimensions its own. Thus the substance of Christ is present under the appearances (and dimensions) of bread and wine, but the dimensions of the transubstantiated bread and wine are not the dimensions of Christ. Christ is present in a tiny host, not in minature, not partially, but whole and entire in the fullness of His mature humanity as well as in the fulness of His divinity. And, while the host we look upon is really Christ Himself, we cannot transfer the dimensions and other accidents of the host to Christ and say that Christ is small, or Christ is round, or Christ is white, or Christ is brittle. For Our Lord uses the extension and other accidents of the host as the ‘veil,’ so to speak, of His presence, but He does not make this extension and these other accidents His own extension and accidents. He is present in the Holy Eucharist sacramentally.”[175]   

 

8. Position (Posture)

 

Position (also called posture) regards the corporeal substance’s way of being in a place, like for instance, “Gerry is standing up,” “Gerry is squating,” “Gerry is sitting down.” This accident indicates the relative position of parts of the same corporeal substance. Position is different from place for it refers to the relative internal arrangement of the various parts of the localized bodily being. Thus, a body can be in different positions at the same place. “Since quantity extends in all static directions, it permits a thing to dispose its parts in different order while remaining roughly in the same place. A man can remain in the same room, and roughly in the same place, while sitting, standing, or lying down. He really changes his posture without changing his place. His members, of course, change place. Posture therefore presupposes the category ‘where,’ somewhat as discrete quantity presupposes continuous quantity, and follows upon it as a further determination of the way a thing is in place. There is no doubt about its reality, as the above examples show.”[176]  

 

9. Possession (State or Habitus)

 

Possession (also called state or habitus) refers to the external adjuncts of a body. It is a special accident expressive of material and external things immediately adjacent to the subject. Some examples: “John is wearing his formal suit and tie”; “John is wearing his Cartier watch”; “John is wearing his leather shoes.” Only humans are capable, in the strict sense, of possessing things, and so this accident properly belongs to the human species alone. “The external things with which a man is in contact and of which he makes use,” writes Owens, “serve to constitute him in one state or another. In the traditional examples, he may be armed, shod, clothed. A new category is thereby set up, grounded, as can be seen from these instances, upon quantity and action and relations like those of proximity and ownership. This category was named by Aristotle echein ‘to have’ and accordingly was called in Latin habitus. The Greek verb, however, as the Aristotelian examples show, was used here in its sense of being in a certain state or disposition. The Latin translation misses this meaning, and is confusing on account of the use of the same term habitus to translate the Aristotelian hexis, or ‘habit’ in the first subdivision of the category of quality.

 

“State is quite evidently a real way of being, as the examples make manifest. It is consequent upon relations, and denominates a man from extrinsic things like weapons, shoes, or clothes. Properly it pertains only to man, on account of his dominion over material things, but reductively states of animals domesticated by man are brought under it, as when a horse is ornamented, saddled, or barbed. Though denominated from what is extrinsic, it is in the subject in the sense of an accident’s dependence in being. Without the subject there could not be the state. Whether the category extends to states like wealth, slavery, power, or marriage, is not determined in Aristotelian tradition. In common with where, posture and when, state is not an inherent actuality in its subject, and is consequent upon relations instead of grounding them.[177] 

 

An Ordering Among Accidents

 

Though it is the substance that is the subject of the accidents, an accident can be called the subject of another insofar as the latter inheres or resides in the substance through the former. For example, color, which is a quality, affects the bodily substance only insofar as the substance is endowed with quantity; a substance without quantity simply cannot be colored. Another ordering among accidents: an accident can be in potency with respect to another accident. For example, a substance which has the accident quantity is in potency to be in a place other than where it currently is. At first the substance and its accident quantity is actually in a certain place, but is also potentially in another place. If it proceeds to that other place, then it is actually in that place, and not just in potency to be in that place. Lastly, certain accidents can be considered to be the causes of other accidents. For example, the action of the conjugal act (an accident) is the action by which husband and wife generate a son or daughter which gives rise to the relations of paternity and filiation between parents and offspring. Another example: having the virtue of fortitude (an accident) gives rise to, or is the cause of, brave actions (accidents) in a person (substance). It is to be noted that as regards a corporeal substance, quantity is its first accident since all other accidents such as quality, action, passion, and so forth, are rooted in the substance by means of its quantity.


 

 

CHAPTER 5

 

ACT AND POTENCY

 

 

We arrive at an initial knowledge of the doctrine of act and potency[178] through the observation of change or motion. Before Aristotle arrived at the scene, there were two great errors concerning the problem of change and stability in beings: the static monism of Parmenides and the philosophy of becoming of Heraclitus.

 

Though Parmenides was the first formulator of the principle of non-contradiction (Aristotle and Aquinas later perfected this formulation) he, nevertheless, denied the possibility of motion or change in the world, adopting a monistic conception of the world, a sad consequence of his univocal conception of being. “Parmenides of Elea and the Eleatic school reasoned more or less in the following way: A thing either is or is not. If it is, it is being; if it is not, it is non-being or nothing. Now when we say that a change takes place, that which comes to be, before the change either is or is not. If it is, it is being; if it is not, it is non-being. But we cannot say that before the change it is; for this would mean that it comes to be what it is already, that being comes to be being. Obviously a thing cannot come to be what it already is. On the other hand, it is equally impossible that what comes to be is not before the change; for this would mean that non-being comes to be, that non-being becomes being. But it is clear that non-being cannot come to be being. Hence we are forced to conclude that change or becoming is positively unintelligible[179] and therefore impossible. What, then, must we say about the so-called changes which we see happening all around us? Only one conclusion is possible: since change is impossible, our senses deceive us when they testify to the reality of change; for reason clearly shows that all change is a contradiction in terms. Moreover, it follows that all reality is but one being. For whatever is different has to differ either by being or by non-being; now what differs by non-being or nothing is not different; while on the other hand things cannot differ by being because being is precisely that by which they are the same. In this way Parmenides was led to static monismmonism, because the admitted the existence of only one thing; static, because he denied that this one thing was subject to any change whatsoever.”[180]

 

Heraclitus, on the other hand, affirmed that only change was real, stability was an illusion, there being no fixed natures or essences in things, everything being in a constant flux; there are no stable beings but only change or becoming. “Rather than deny the obvious testimony of the senses for the reality of change, he (Heraclitus) chose to deny the reality of being. According to him, reality is not being but becoming or change. Whatever seems to be is nothing but a deception, just as a stream may seem to be always the same, but in reality is always changing. His theory was aptly summarized in the famous formula panta rei, ‘everything is in a state of flux.’”[181]

 

It was Aristotle who arrived at a solution to the Parmenidean and Heraclitean errors concerning change and stability in beings (entia) with his doctrine of act and potency. “No solution was considered to be satisfactory before Aristotle solved the puzzle. With Parmenides, Aristotle maintained that being is real, and with Heraclitus, he asserted that change is real. The solution of the apparent contradiction he sees in the fact that a distinction has to be made in being itself. Being, he says, ‘is distinguished in respect of potency and complete reality,’[182] or as it is usually expressed by scholastic philosophers, being is divided into being-in-act and being-in-potency. In other words, Aristotle admits that there is a middle ground, not between being and non-being, but between being-in-act and non-being, and this middle ground is called being-in-potency. ‘We say that potentially, for instance, a statue of Hermes is in the block of wood and the half-line is in the whole, because it might be separated out, and we call even the man who is not studying a man of science, if he is capable of studying.’[183] Thus when we say that a thing comes to be, this does not mean that non-being becomes being, but merely that being-in-potency becomes being-in-act, and this does not imply any contradiction. Therefore, being and change are both intelligible, and there is no reason to reject the reality of either.”[184]

 

The change or motion that we see around us is definitely real; it is the passage from being in potency to being in actuality. It is the successive actualization of the potency. For example, hot water is in a state of actuality and cold water is in a state of potentiality towards being hot water. When water is heated with fire it slowly starts to boil. This process of water being heated is a transition from cold water (the state of potentiality) to hot water (the state of actuality). What is formerly in potency undergoes a successive actualization of the potency towards a state of actuality (in hot water).       

 

Potency is the capacity to have a perfection while act is the perfection which a subject possesses. Act is contrasted to potency, which is the potentiality to receive the perfection or act. Potency and act are directly known through experience as correlative to each other. In the case of potency its very constitution is to be directed towards some type of act. Because they are primary and evident notions, they cannot be strictly defined but only described by means of examples and by contrasting these notions with one another: “Strictly speaking, these terms cannot be defined. Act and potency are immediate divisions of ‘being.’ In order to be defined, ‘being’ would have to be their proximate genus in the definition; but ‘being,’ as was pointed out before, is not a strict and true genus.”[185] Though act and potency cannot be strictly defined, since a strict definition consists of a genus and a specific difference, and these cannot be found in the most primary and fundamental notions of being, nevertheless, “potency may be described by means of its relationship to act as the capacity for an act. Act itself, however, cannot even be described in this way by means of a relationship to potency. For instance, it would not be correct to describe act as the actuation or fulfillment of a potency. For in doing so we should imply that every act is a fulfillment of a potency and therefore presupposes potency. While, as a matter of fact, it is true that most acts presuppose potency, this is not so because they are acts, but because they are limited acts. Act as act merely implies perfection, and not that this perfection is limited. All we can do, therefore, to clarify the concept of act is to give examples.[186] The act of ‘building’ is in him who is building now; but the potency of ‘building’ is in him who is not building now, although he is capable of it; the act of ‘heat’ is in that which is hot now, but the potency of ‘heat’ is in that which is not hot now, although it is capable of being hot; the act of ‘animality’ is in that which is animal now, but the potency of ‘animality’ is in that which is not animal now, although it is capable of becoming animal; etc.”[187]

 

Explaining the philosophical principles of act (actus) and potency (potentia), Bittle has the following words to say: “According to philosophical terminology an act (Latin, actus) means any entity of whatever kind and nature which perfects and determines a thing in its being. Thus, the term ‘act’ includes the power or faculty as well as the operations of that power, because this power is a perfection for the thing which has it; it includes every accidental modification of a being because every accident (e.g., color, heat, weight, shape, etc.) perfects the being in some way; it includes every essential entity, because nothing is more perfecting for a thing than its essence; it also includes existence, because existence is a perfection for a being. Whatever a being has or is in a positive manner is an ‘act’ for it. Man’s substantiality, materiality, life, sentiency, and rationality, are ‘acts’; his quantity, size, shape, age, sex, color, health, are ‘acts’; his powers of reason and of will, of locomotion, of digestion, of seeing, hearing, feeling, etc., all these are so many ‘acts,’ perfecting and determining his being in its respective order as ‘man.’ And so with all other beings. The term ‘act,’ therefore, has a specialized and technical meaning, much wider than its signification in ordinary language.

 

Potency (Latin, potentia, power) is the capacity or aptitude for something. It is the correlative term to ‘act.’ ‘Potency’ is always the capacity or aptitude in reference to something which a being is not or has not, but which it can be or can receive. Any being, in so far as it has not as yet received a certain ‘act’ or perfection, but is capable of receiving it, is said to be ‘in potency’ for this act. Hydrogen, for example, has the ‘act’ of hydrogen; and oxygen has the ‘act’ of oxygen: but both have the ‘potency’ of water; they are ‘actually’ hydrogen and oxygen, but ‘potentially’ water. Water, on the other hand, is ‘actually’ water; but it is ‘potentially’ hydrogen and oxygen, because it has the aptitude to be resolved into them. Common salt is ‘actually’ salt, but it is ‘potentially’ chlorine and sodium.

 

“If we consider the relation between ‘act’ and ‘potency,’ we find that it is the relation of the completing to the incomplete, the determining to the determinable, the perfecting to the perfectible. Since these are relative terms, it is obvious that an entity may be a determination and perfection for a being in one way and thus be an act, and it may also be determinable and perfectible in itself and thus be a potency. The intellect, for example, is a positive perfection of the mind, and thus an ‘act,’ for man; but the intellect itself is perfected by the actual thinking process (which is an ‘act’ for the intellect), and it is, from this point of view, a ‘potency.’ Similarly, the power of locomotion is a perfection, an ‘act,’ for a resting dog; but the act of running is a perfection for this power of locomotion, and the power of locomotion is thus seen to be a ‘potency’ with regard to this act of running. An entity, therefore, can be both an ‘act’ and a ‘potency,’ when considered from different viewpoints; but never with reference to the same perfection under the same respect, because that would violate the principle of non-contradiction.”[188] 

 

Act and potency should be considered under two aspects, namely, the physical (which is linked to change or motion), and the metaphysical. Regarding the physical aspect, act and potency form the elements that make change or motion understandable. Here, what is actual cannot be at the same time potential and vice versa. Hot water cannot be cold water at the same time and in the same respect. Change is the transition between being in potentiality and being in actuality.

 

Regarding the metaphysical aspect, act and potency form the stable constituent principles of all things (finite things, that is, which excludes God who is Pure Act without any admixture of potentiality whatsoever), so much so that the potency, even after having been made actual, continues to be a co-principle of its corresponding act. In all material beings, which are hylemorphic composites of prime matter (potency) and substantial form (act), prime matter remains even after reception of its form.  

 

Potency is that which can receive an act or already has it. This statement implies a number of things: 1. that potency is distinct from act; 2. that act and potency are not complete realities but rather principles or aspects found in things; 3. that potency is to act as the imperfect is to the perfect; and 4. that in itself potency is not a mere privation of act but is a real capacity for perfection.

 

1. Potency is Really Distinct from Act. This can be shown when act is viewed as separated from its corresponding potency. For example, the exterior sense of hearing sometimes is hearing and at other times is not. Yet no one doubts that man has the potency or power for hearing. The exterior sense of sight is sometimes seeing and other times is not, yet men have the potentiality or capacity to see. A person may at times be walking, and at other times he may be at rest, yet he still has the potentiality or capacity to walk. These various potencies or powers of man may not be currently in use, that is, they may not be actualized, but they still remain potencies. Thus, potency is characterized as being the capacity to have an act or by being a receptive subject, and is therefore distinct from act. “The constituent principles of a reality which are called potency and act must be really distinct. For that which perfects cannot be really the same as that which is perfectible; otherwise the perfectible would give itself an act which it does not have, so that being would come from non-being. Moreover, if potency and act were not really distinct, that which limits and that which is limited would be really the same, so that act would limit itself.

 

“From the real distinction of potency and act it follows that nothing can be potency and act in the same respect because this would imply that that which perfects is really the same as that which is perfected or perfectible. This assertion, however, does not mean that a higher degree of the same act cannot be received by a subject whose potency is already partially actualized. An intellect, for instance, which has already been actualized with respect to the knowledge of one thing can continue to acquire more knowledge and thus becomes more actualized. But that part of a potency which has become actualized is no longer potency. On the other hand, in different respects a thing may be in potency and act at the same time. For instance, the power of speech may be considered as an act insofar as it perfects man’s nature, but insofar as it can be perfected by the act of speech it is a potency. Thus it is quite possible that what is an act in one order is a potency in a different order. It is even possible for an act to be unlimited in one order and limited in a different order.”[189]  

 

2. Act and Potency are Not Complete Realities but Rather Principles or Aspects Found in Things. Act and potency are the distinct co-principles of a thing. Act is not a subsistent being and potency is not a subsistent being; rather, they are intrinsic principles of a finite being.    

 

3. Potency is to Act as the Imperfect is to the Perfect. In its strict meaning, act means perfection, a completion, something determinate. Potency, on the other hand, is an imperfection, a capacity for perfection. The fully finished marble statue of the Pietà in St. Peter’s basilica is something determinate, a perfection, something in act, while the shapeless block of marble that was the initial material that Michelangelo would later use would be the determinable, the imperfect, the potency, the potentiality for perfection.  

 

4. In Itself Potency is not a Mere Privation of Act but a Real Capacity for Perfection. The external sense of sight, when not in use, is not a mere privation, but is at that very moment potentially capable of being actualized by the actual operation of seeing, which is a perfection.  

 

Division of Potency

 

Subjective Potency and Objective Potency. Also called logical potency, objective potency is the capacity of a non-existent being for existence, founded in the non-repugnance of a subject and predicate. For example, man was objectively possible before he was created. Subjective potency, which is real potency, is the capacity or aptitude of an existing being for an act (for example, the potency by which a piece of marble can receive the act of the form of a statue).   

 

Passive Potency and Active Potency. Passive potency is the capacity a thing has to be changed by another as other, while active potency is the power to effect a change in another as other. Passive potency is the capacity to receive while active potency is the power to do. Passive potency can be pure or mixed.

 

Pure Potency and Mixed Potency. Pure potency is potency that is not actualized in any way, being essentially and totally indeterminate. It exists in the corporeal beings and is called prime matter. Mixed potency is all that which is actuated in part but is still further actualizable. This pertains to every finite being. Thus, for example, water is in act with respect to the form of water, but is in potency with respect to heat.

 

Division of Act

 

Pure Act and Mixed Act. Pure act is act which admits of no potency whatsoever. This is God Himself. Mixed act is act which is received into potency, or it is act which is in potency to act of another order. Mixed act is either entitative or formal.

 

Entitative Act and Formal Act. Entitative act is the very act of being (esse) of a finite thing. Entitative act is a mixed act inasmuch as it is received into a potency which limits it, not inasmuch as it is in potency to further act, for esse is the ultimate act. Formal act, the act of essence, act in the order of essence, is the act by which a thing is determined and perfected in its species; v.g., substantial form.

 

First Act and Second Act. First act is act which does not presuppose an anterior act, but awaits a subsequent act; v.g., substantial form. Second act, on the other hand, is act which presupposes an anterior act; v.g., an accident. Therefore, second act is accidental act. An example of second act would be acts of thinking (the operative power of intelligence would, in contrast to thought, be an active potency). 

 

The Primacy of Act

 

Act has primacy over potency in a number of ways: 1. Act is prior to potency as regards perfection; 2. Act has cognitive priority over potency; 3. Act has a causal primacy over potency; and 4. Act has a temporal primacy over potency.

 

Act is Prior to Potency as Regards Perfection. Act is perfection while potency is imperfection waiting to be perfected by act. A thing is perfect insofar as it is in act while imperfect while in potency.  Being in act constitutes the end or goal towards which being in potency strives for. Sight, for example, is ordered towards the goal of seeing, and without the latter activity the operative potency would be frustrated. With regard to man, his human body is the potency which receives the rational soul as its act and becomes subordinated to this perfection. Therefore, act is prior to potency as regards perfection. 

 

In line with Aristotelian metaphysics, Krapiec speaks of an ontic (or substantial) primacy of act over potency, writing: “What should we understand by the term ‘ontic’ or ‘substantial’ primacy? According to Aristotle, essence – substance – is the chief and primary manifestation of being, and as such is something perfect. Essential primacy is, therefore, synonymous with perfect primacy. The question, then, is what is more real, what constitutes the ‘reason of being’: act or potency? Also, the perfection of a thing can be apprehended in two aspects: either by reason of its form or by reason of its end.

 

“Form is the factor perfecting the thing. Act is essentially more perfect than potency in the formal aspect. Why? Let us consider how things arise. The form of a thing is what designates the thing’s essence; it is the basis for defining the thing; it ‘comes’ to the thing as its ultimately determining factor. Now, the form of the thing is act, for forms are acts in relation to passive potency, that is, in relation to matter with all its dispositions. If, then, form is act and form is the essential perfection of a thing, since it constitutes the thing’s essence, then act is the essential perfection of a thing, since it constitutes the thing’s essence, then act is the essential perfection of the thing; it is essentially more perfect than potency, than all the factors that dispose the thing to receive form-act.

 

“The essential perfection of act in relation to potency becomes still more apparent when act is analyzed as the thing’s end. The final cause ‘justifies’ all other causes, for the real motion and generation of a thing ultimately depends on its end, which as a motive force is the reason of being of action. In relation to potency, act is an end, and the end is what is more perfect in the order of causes. Consequently, act is also something most perfect, and so, in relation to potency, act is a perfection.

 

“Act is an end in the order of both passive and active potency. In the realm of passive potency, matter is not determined until it possesses act. The emergence of act, therefore fulfills matter and determines it, as the end determines the efficient cause to a particular kind of action. Act is likewise an end, and thus also a perfection, in relation to active potency, since such potency exists for action. The very arrangement of elements constituting this potency points to the fact that active potency is ordered to act-action, without which it is completely unintelligible. Act, therefore, lies at the basis of the understanding of passive and active potency, insofar as the understanding of a thing takes place by apprehending its formal and final causes.

 

“If act is essentially more perfect than potency (as is clear from the analysis of formal and final causality, with which causes act is identified), then each thing is perfect to the extent it is in act and imperfect to the extent it is in potency (unumquodque perfectum est, inquantum est actu, imperfectum inquantum in potentia). Moreover, if a thing is perfect to the extent it is act, that is, if the measure of perfection is the act or the ‘actuality’ of a thing, then pure act is all-perfect, and everything else apart from it is only relatively perfect (actus purus est omniperfectus, actus in aliquo ordine purus in eo est totaliter perfectus).”[190]          

 

2. Act Has Cognitive Priority over Potency. Act has a cognitive priority over potency as the latter is ‘defined’ by the former, that is, in relation to the former, as the ability or capacity to build is known from the act of building, or the ability or capacity for sight is known from the act of seeing. “Any potency is known through its act, since it is no more than the capacity to receive it, possess it, or produce a perfection. Consequently, the definition of each potency includes its own act, which is what differentiates it from other potencies. Thus, hearing is defined as the power to grasp sounds, and the will is defined as the power to love the good. The primacy of act in knowledge is based on the very nature of potency, which is nothing but the capacity for an act.”[191] “Cognitive primacy,” says Krapiec, “occurs when the cognition of one thing requires the prior cognition of another, so that the one thing may be cognized in light of the other. Act enters into the understanding of potency; act is the reason of the cognition of potency; and, therefore, act is cognitively prior to potency. But why does act conceptually justify potency? Potency is real when it has within it real dispositions in relation to some act. In other words, potency becomes something real through its real ordination to act. Consequently, it is found in relation to act, and this is a relation that defines potency through act, without which potency is unintelligible. This is also why the names of a real potency are not derived from the potency, but from the act that defines and realizes it, the act to which the given potency is ordered.

 

“From this it follows that the understanding and explanation of potency takes place through act, while the understanding of act takes place spontaneously, by way of ‘induction’ and through an analysis of examples (potentia innotescit et definitur per actum, actus autem non potest definiri). Properly speaking, neither act nor potency has a strict definition, since they are the first elements of being and cognition; still, this very cognition we have of act and potency is governed by a certain subordination. On the basis of a previously cognized act, by means of intuition or a ‘quasi demonstration,’ we can cognize the character of potency. Act expresses in itself a certain perfection, a certain completed being, and so it can be cognized without appealing to potency, whereas potency can never be cognized without act. Act, therefore, ‘specifies’ potency and endows it with a determinate content (actus explicat potentiam, seu potentia sumit speciem ex actu).”[192]

 

3. Act has a Causal Primacy over Potency. What is in potency does not become actual without the influence of something already in act. For example, fire (something in act) causes cold wood (in potency) to become hot and then to be fire. Without that prior act cold wood would never of itself be in act. Either it burns by fire (in act) or is heated by the sun (in act) which causes the cold wood to be hot. Therefore, act has a causal primacy over potency.    

 

4. Act has a Temporal Primacy over Potency. Potency does indeed have a certain temporal primacy over act; for example, the operative powers of intellect and will (active potencies) come before the production of the activities of thinking and willing (second acts). However, the operative potencies of intellect and will point to an agent cause, the soul, which is prior in act. Another example: an acorn (in potency) came before the full grown pine tree (in act), but this acorn had to be, of necessity, the fruit of a prior tree (in act). Therefore, act has a temporal primacy over potency. “In examining the temporal primacy of act in relation to potency, Aristotle makes certain distinctions, separately considering potency in a concrete case, where the potency in question is ‘passive potency,’ and potency and act as such, apprehended in their content absolutely. ‘Passive’ potency, apprehended in a concrete case in some individual, is temporally prior to act. On the other hand, act as act, conceived of in terms of the species, is temporally prior in relation to potency. When we consider some individual, this here human being, Socrates, we know that ‘this here’ human being at some previous time did not exist. But if he now lives and exists, then before he came into existence, before he became act, he existed in potency in his causes. The state of potency, therefore, temporally precedes the state of act in the concrete case: the life of a human being. Hence, potency in the order of actualization, in the order of coming into existence, is prior to act in concrete individuals. A similar situation occurs with every being that has arisen in time. Real potency, however, is always realized, actualized, through some act. That which is in potency does not of itself pass from potency to reality, or act; it does not actualize itself. This actualization takes place under the influence of some factor external to potency, an acting factor: act.”[193]      

 

The Relation Between Act and Potency as Constitutive Principles of Being

 

Regarding the relation between act and potency as principles of being, we can state the following: 1. Potency is the subject in which the act is received; 2. Act is limited by the potency which receives it; 3. Act is multiplied through potency; 4. Act is related to potency as that which is participated to the participant; and 5. The act-potency composition does not destroy the substantial unity of being.

 

1. Potency is the Subject in which the Act is Received. We look at a man, for example, and begin to know his various perfections (acts), like the color of his hair, eyes and skin, without ever denying that these perfections reside in that person (potency), who is the subject of these perfections (acts).     

 

2. Act is Limited by the Potency which Receives It. Every act received in a subject is limited by the capacity of that subject. The perfection of redness in an apple is limited by the substance apple, its recipient. An apple can only contain as much redness as the dimensions of that fruit allow. Unreceived act is in itself unlimited, and when one finds limited instances of act, it is because of a potency which receives and limits it.            

 

Wippel on Unreceived  Act as Unlimited

 

Against the Dutch scholar Rudi te Velde who denies that Thomas Aquinas ever taught the principle “that act is not limited except by a distinct potency that receives it” with regard to act of being and essence, the Thomist scholar John F. Wippel presents texts of the works of St. Thomas where the he holds the principle. The axiom is this: unreceived act is unlimited and when one finds limited instances of act, especially the act of being (esse), one must account for this by appealing to a distinct principle that receives and limits it. In the first part of his essay entitled Thomas Aquinas and the Axiom that Unreceived Act is Unlimited, published in The Review of Metaphysics in 1998,[194] Wippel, an expert on the metaphysical thought of Aquinas, presents texts where the Angelic Doctor either implicitly or explicitly holds the axiom. In the second part, Wippel shows, against the position of Jean-Dominique Robert,[195] that Thomas employs the axiom or principle as an argument for the composition and distinction between essence and act of being in finite creatures. Wippel presents a text from the early work of St. Thomas, namely the sed contra of d. 8, q. 5, a.1 of the first book of the Commentary on the Sentences, that supports that every creature is really composed of esse and essentia (quod est): “Every creature has finite esse. However, an esse that is not received in something is not finite, nay it is unrestricted (absolutum). Therefore every creature has an esse that is received in something, and so must have these two at least – namely, esse, and that which receives esse.”[196] Aside from affirming that unreceived act is unlimited or infinite, Thomas applies the principle that act is limited by a distinct potency that receives and limits it, to esse and essence. Wippel writes concerning the text: “Here we have a very clear expression of the first part of our axiom, to the effect that unreceived esse is not finite, but unrestricted or infinite. Moreover, we also have an immediate application of this to the situation of creatures. Because every creature is finite, it must have both an act of being that is received in something, and something that receives its act of being. Otherwise, according to the axiom, its act of being would be unlimited. Therefore it consists of these two at least, an act of being, and that which receives it…According to Thomas’ thinking, act, especially the act of being, is not self-limiting. It is not enough to appeal to an extrinsic principle or cause to account for the intrinsic limitation within a finite entity of that which is not self-limiting. Therefore, Thomas would conclude to the need for an intrinsic principle therein that receives and limits its act of being. For Thomas, of course, the act of being and the principle that receives and limits it must be related to one another as actuality and potentiality.”[197] For Aquinas, Wippel observes, the axiom that ‘unreceived act is unlimited and that where one finds limited instances of act, especially the act of being, one must account for this by appealing to a distinct principle that receives and limits it,’ is a self-evident one.[198] Wippel qualifies this, his view, saying “for Aquinas” because acceptance of this axiom, at least in its application to the act of being, presupposes that one understand that, for St. Thomas, esse is the act of acts, and because of this, is the perfection of all perfections. His position is unmistakable in De Potentia q. 7, a. 2, ad 9. Wippel observes that “if this is one’s understanding of esse, and it surely is Aquinas’s, it will only be reasonable for him to conclude that esse is not self-limiting. To say anything else would be to account for the limitation and imperfection (the negation of further perfection) of a given being by appealing to that which is its ultimate principle of actuality and perfection. For Thomas, actuality and perfection go together.”[199]

            

Norris Clarke on the Limitation of Act by Potency

 

In an influential essay written in 1952,[200] W. Norris Clarke rejects what he calls the “traditional interpretation” of Aristotle on the origin of the principle that act is limited by a potency which receives it. He laments the fact that up until recently the influence of Neoplatonism upon St. Thomas’ metaphysical thought had been somewhat obscured by the idea that Thomas simply ‘baptized’ Aristotle’s philosophy. He cites the thought of Reginald Garrigou-Lagrange as an example of the traditional interpretation that the doctrine of the limitation of act by potency in its essentials had already been the position of Aristotle, but that it was Thomas Aquinas who utilized this doctrine, developed and perfected it, by applying it to the realm of essence and act of being, something that the Stagirite failed to accomplish.

 

Norris Clarke quotes Garrigou-Lagrange on the principle of the limitation of act by potency: “Aristotle already taught this doctrine. In the first two books of his Physica he shows with admirable clearness the truth, at least in the sense world, of this principle. Act, he says, is limited and multiplied by potency. Act determines potency, actualizes potency, but is limited by that same potency…Aristotle studied this principle in the sense world. St. Thomas extends the principle, elevates it, sees its consequences, not only in the sense world, but universally, in all orders of being, spiritual as well as corporeal…”[201] Norris Clarke criticizes this interpretation, saying that it is simply not backed up with evidence, that is, with proper quotes from Aristotle’s works, in particular, with quotes from the first two books of the Physics. Having consulted Garrigou-Lagrange’s book, I can say that Norris Clarke is indeed right concerning the lack of evidence, that is, the lack of pertinent quotes from Aristotle, to support his claim. In fact, Norris Clarke writes that he could not find the pertinent quotations of Aristotle in any of Garrigou-Lagrange’s works regarding his traditional interpretation: “Despite the categorical assertion of Fr. Garrigou-Lagrange in the above quotation, neither here nor anywhere else in his numerous writings on this doctrine does he ever quote or refer to any precise text where Aristotle himself affirms the limiting role of potency with regard to act.”[202] Having also consulted all the texts of the Stagirite’s works regarding act and potency Norris Clarke relates that he could not find Aristotle teaching that act is limited by potency anywhere at all: “A careful examination of the entire first two books of the Physics, referred to as teaching the doctrine clearly, reveals that nowhere in them does there occur any mention of the word or the idea of limit in connection with potency. Nor have I been able to find in any other Thomistic author a precise reference to any text of Aristotle which would bear out the above position. These puzzling facts led the present author to undertake a direct examination of all the passages in Aristotle which deal with either act and potency or its applications. The results were entirely negative. Nowhere could we discover any text from which one could conclude, in accord with the accepted norms of objective historical interpretation, that Aristotle himself ever held the doctrine that potency plays the role limiting principle with respect to act, which if unmixed with potency would be unlimited. This textual analysis receives strong confirmation from the fact that if we turn to the modern scholarly studies of Aristotle as well as to his ancient commentators we find that not one of them so much as mentions the principle of the limitation of act by potency as forming part of the Aristotelian teaching on act and potency.”[203] He likewise observes that St. Thomas himself does not mention Aristotle advocating the doctrine in his Commentary on the Metaphysics of Aristotle, not even in book nine of the commentary which deals exclusively with the doctrine of act and potency.

 

For Norris Clarke, Aristotle teaches the opposite of Thomas’ doctrine, holding that the principle of limit is identified with perfection or act, and the unlimited with imperfection or potency. When the doctrine of act and potency is applied to prime matter and substantial form Aristotle holds that the role of form (act) is to impose a limit on the formless infinity of prime matter (taken by itself) and thus to confer upon it determination and intelligibility.[204] For Thomas, of course, it is the reverse: substantial form (act) is limited by the prime matter (potency), accidents (acts) are limited by substance (potency), and act of being (act) is limited by the essence (potency) which receives it. Where did he get this reversal of doctrine compared to Aristotle? The Platonic-Neoplatonic participation framework, which was alien to the Aristotelian perspective. For Norris Clarke, the Stagirite explicitly rejected “all ontological participation or transcendence of material forms.[205] It is quite true that he does teach explicitly that forms of themseves are unique and can be multiplied only by reception in matter.[206] But nowhere does he say or imply that such multiplication involves a process of limitation by matter of a form which by itself could be called infinite. On the contrary, he insists against Plato that every specific form is received whole, entire, and equally in every individual of the species. The guiding image here is clearly not that of matter or potency as a container which contracts the plenitude of form or act; it is rather that of form as a stamp or die, fully determined in itself, which is stamped successively on various portions of an amorphous raw material such as wax or clay. Such a multiplication can appear rather as an expansion than as a limitation of the form. The two perspectives are quite different, though, as St. Thomas has shown, by no means mutually exclusive. It is poor history, therefore, to argue from St. Thomas’s much richer analysis of multiplication of form in terms of participation and limitation to the conclusion that Aristotle also must have understood his own theory of multiplication in the same way. The fact is that there is no trace of such an interpretation in the commentaries of Aristotle until the advent of Neoplatonism.”[207] 

 

What then was the role of Aristotle’s act and potency composition, according to Norris Clarke’s interpretation? “There is only one: as function of the problem of change.”[208] What St. Thomas did to effect his doctrine of the limitation of act by a distinct potency which receives it was to harmonize the initial Aristotelian doctrine of act and potency with the Neoplatonic doctrine of participation of finite (composed) in infinite (uncomposed): “On the one hand was the central piece of Aristotelian metaphysics, the doctrine of act and potency. Its weakness was that it was geared exclusively thus far to the context of a change process. Its strength was that it was admirably adapted to express a structure of metaphysical composition within a being, while at the same time safeguarding the intrinsic unity of the composite resulting from the union of two incomplete, correlative principles. On the other hand was the central piece of the Neoplatonic metaphysical tradition, the participation-limitation framework. Its strength lay in its ability to express satisfactorily the fundamental genetic and hierarchic structure of the universe, that is, the relation of creatures to a first Source conceived at once as exemplary, efficient and final cause of all. Its weakness lay in the fact that it habitually left vague, unexplained, and dangerously ambiguous the unity of the composite resulting from the superposition of participated on participant, whether of form on matter or of higher form on lower form. The achievement of St. Thomas was to recognize that the strength of each doctrine remedied precisely the weakness of the other and to fuse them into a single highly original synthesis, condensed in the apparently simple yet extremely rich and complex formula: Act is not limited except by reception in a distinct potency. In order to effect this synthesis, however, he had to subject both doctrines to profound modifications. First, he had to empty the participation-limitation structure of its original Neoplatonic content, that is, of the vast hierarchic procession of reified universal concepts – the Porphyrian tree transplanted into reality – so characteristic of the whole Platonic tradition (at least in its Aristotelian interpretation), dominated by the primacy of form and the ultra-realism of ideas. In its place he substituted as the fundamental ontological perfection of the universe the supra-formal act of existence, participated first directly by essential form, as limiting potency in pure spirits, then dispersed, so to speak, in material beings, by being communicated through specific forms to their multiple participations in matter. Secondly, he had to disengage the Aristotelian act and potency theory from its hitherto exclusive attachment to a change context, and to add to the already existing dynamic ‘horizontal’ function of potency a new dimension, the static ‘vertical’ function of receiving subject, limiting a higher plenitude in a participation framework. Furthermore – and this was the most violent wrench to the old Aristotelian concept – this new second function could now be found in some cases entirely separated from and even exclusive of the first, as in the case of potency as essence of the essentially incorruptible, immutable pure spirits…The final result of the fusion of the two theories into a single coherent synthesis can thus be called neither Aristotelianism nor Neoplatonism. It is something decisively new, which can only be styled ‘Thomism’…Thomas was the first thinker in Western philosophy to be able to effectuate a successful synthesis of the two basic insights of the Aristotelian and Neoplatonic traditions and thus to fuse into one the best elements of the two main streams of western philosophical thought.”[209]            

 

3. Act is Multiplied Through Potency. The same act can be present in many individuals which can receive it, as for example, when the specific perfection “apple” is possessed by many individual apples because it is present in a potency, namely, prime matter. The same substantial form is multiplied in many individuals of the same species. Accidents (acts) are also multiplied by their respective potencies, namely substances. The accident “red,” for example, is multiplied insofar as there are many objects having that same color.

 

Concerning the multiplication of act by potency, Gardeil writes: “If potency is the (intrinsic) principle of limitation, it is also, and for that very reason, the principle of multiplication. Suppose an act that is not limited by potency; such an act is unlimited or perfect, and therefore unique. Unique, because if two beings were equally (and infinitely) perfect, one could not differ from the other; in fact, they would cancel each other. Wherever, then, perfection is plural, the perfection must be limited. But we know it is not limited by itself, hence by something not itself; and this, as we have learned, is potency, which limits act (or perfection) by receiving it and thus makes possible its plurification.”[210]  

 

Krapiec explains that “the question of the limitation of act by potency is connected with the problem of the multiplicity of beings, an ancient problem whose roots lie in the Eleatic school. How is the multiplicity of beings to be explained, if act is temporally prior and ultimately this act can only be pure act? Once again, it is not a question here of a causal interpretation (e.g., that this multiplicity arose as a result of the causation known as creation), but of an immanent explanation: What is the internal cause of the fact that beings are many rather than one? If they were caused as multiple, then what in them is the inner reason of this multiplicity?

 

“This problem becomes even more acute when we consider that act itself viewed analogically, despite the fact that it is something analogical or basically diverse in its construction, does not express any diversity or multiplicity when viewed from the side of act itself, from the side of the primary analogate (i.e., in its pure form, for each transcendental analogy has a primary analogate). Act is then absolutely identical with itself.

 

“What is the reason for multiplicity in beings? If act as act expresses identity with itself (realized only in the primary analogate of transcendental analogy), then multiplicity is derived not from the side of act but from the side of some potency that limits and, together with act, constitutes a being. Why?

 

“The thesis of the multiplication of being is based on the prior thesis of the limitation of act by potency. All multiplication requires limitation. If the principle of the limitation of act by potency did not hold, then the fact of the multiplication of beings would also not be possible – and then only one, absolute, all-perfect being would exist. Hence, if manifold beings exist, they presuppose limitation, and so they presuppose potency.

 

“St. Thomas’ argument concerning the impossibility of the existence of many Gods, or supremely perfect beings, will help illuminate this point. If two supremely perfect beings existed, then they would either differ from one another in some respect or not differ in any respect. If they did not differ in any respect, then they would not be two beings but one and the same being. Consequently, only one being would exist, which is contrary to the assumption of the existence of two beings. If, on the other hand, they differed in some respect, then one being would have a perfection not possessed by the other. The being not possessing that perfection would already be a limited being, since it would lack the ontic perfection possessed by the other being. Now, the cause of limitation lies in potentiality. And so the cause of the multiplication of being also lies in the potentiality of being. Ontic multiplicity, therefore, necessarily presupposes ontic limitation.

 

“Hence, just as the following formulation was operative in relation to the validity and binding force of the principle of limitation, namely, that ‘act in the order in which it is act cannot be limited,’ so, too, here we should affirm the principle that ‘any act in the order in which it is act can be multiplied only by passive potency.’ Ontic multiplication in this case refers to the individuation of material beings.”[211]  

 

4. Act is Related to Potency as that Which is Participated to the Participant. The doctrine of act and potency can be understood using the theory of participation.[212] To participate means to have something in part or something in a partial manner. This presupposes that there are other subjects that possess the same perfection, none of them possessing that said perfection in full. Also, in participation, the subject cannot be identical to what it possesses; the subject merely possesses this perfection by participation only. The subject of participation has the perfection, possesses the perfection; he is not the perfection, he doesn’t have the perfection by essence, that is, in a full and exclusive manner, by being identical with it. Creatures have the act of being while God is the Act of Being by Essence, that is, Essence and Act of Being are identical in the Divine Being. Now, while pure actuality is act by essence, the relationship of act and potency is one of participation. The subject (potency) capable of receiving a perfection (act) is the participant, and the act itself is that which is participated in by the subject.

 

5. The Act-Potency Composition does not Destroy the Substantial Unity of a Being. Act and potency are not subsistent beings (entia) in themselves but rather constituent principles of finite beings (entia). They are not things but rather the co-principles of a thing. Potency is by nature a capacity for perfection, a capacity towards an act, to which it is essentially ordered and without which it would not be able to exist at all (prime matter [potency], for example, exists for the form [act], without which it simply would not exist). Potency’s union with its act cannot therefore give rise to two individual things, two separate beings.  

 

Act and Potency Among Philosophers

 

It was Aristotle who first provided us with an adequate explanation of the doctrine of act and potency. St. Thomas Aquinas would later perfect the doctrine of act and potency viewed from the metaphysical aspect (prime matter-potency and substantial form-act; substance-potency and accidents-acts; essence-potency and act of being-act), and advocate the axiom that where one finds limited instances of act, it is because of a distinct limiting principle (potency) which limits it. Both Aristotle and St. Thomas teach the real distinction between act and potency and the priority of act over potency. Against the monism of Parmenides, they acknowledge the reality of motion and becoming, but at the same time teach the priority of being over becoming. They teach that God is Pure Act while all finite beings are compounds of potentiality and act. Thomas stresses the fact that between God and creatures there is an infinite difference. Parmenides and Spinoza, on the other hand, refuse to admit the notion of potentiality, for, by itself, it is wrapped in obscurity. If all that is, is pure act or wholely act, then motion must be illusory and unreal, teaches Parmenides. The panlogician Hegel would use act and potency in a sense different from Aristotle and Aquinas. For him, act and potency is transformed into the affirmation and negation of the spirit. Heraclitus and the vitalist Henri Bergson deny the distinction between act and potency for the reason that being is illusory. What is real is pure becoming, pure change, and thus pure act cannot exist. This position also holds the pantheistic view that God must possess the same nature as things. Such thinkers, including Herbert Spencer, make pure change the fundamental category of reality.

 

 


CHAPTER 6

 

ESSENCE (ESSENTIA)

                             

 

Essence (Essentia)

 

The substances we see around us are not simple but are composed of two principles: essence and act of being, the former being related to esse as a potency, and the latter being related to essentia as act. Essence (essentia) is the proper potency of the act of being (esse) and together with this act constitutes the substance (substantia). Essence[213] confers upon this substance a specific manner of being and is defined as that by which a thing is what it is. It is  “that through which and in which a being has its act of being (esse).”[214] Essence is found truly and properly in substance while in accidents it is found in a qualified sense. Aquinas writes: “Just as the term ens is applied in the absolute and proper sense only to substance, and to accidents in a secondary, derived way, essence truly and properly pertains to the substance, and to the accidents only in a certain way, and from a certain point of view.”[215] Therefore, when we refer to the essence of something without qualification we refer to the essence of its substance, not to the essence of its accidents.

 

Essence as Quiddity, the Universal and Nature

 

Essence is often times referred to as a quiddity, a universal, or as a nature. Why is this so? Alvira, Clavell and Melendo explain that “as the ‘specification of the mode of being of a thing,’ the essence gives rise to a series of basic properties which give us a better understanding of essence. These properties themselves give rise to a set of terms which refer to one and the same reality, while differing with respect to the aspect of that reality which is considered. They are, however, sometimes employed in an undifferentiated way in common usage.”[216]  

 

Essence as Nature. As the principle of operations, essence is called nature. Nature is essence from the viewpoint of its proper activity. Nature is essence considered as the ultimate principle of operations in a being. Nature is the essence considered as the root principle of activities of a being. It expresses the dynamic character of being. A horse, for example, acts in one way and not in another because it has being in a determinate way, conditioned by its essence. Thus, each nature has a corresponding type of specific operations. Trotting, galloping, eating grass and neighing, for example, are natural to the horse because they are operations which arise from horse nature or horseness itself. “Every being” explains Dougherty, “has certain powers or faculties which dispose it to act in a certain way, such as the faculty to know, the faculty to hear, the powers of a plant for photosynthesis. No finite being acts immediately but rather mediately through certain powers for certain acts. Yet the powers or faculties of a being for acting are not adequate to explain a being’s activities. Uniform and stable patterns of activities are proper to a species because of a basic determination for such uniform and proper activities in the very nature of the species. It is grounded in their very essence or nature.”[217]

 

Essence as Quiddity. Insofar as essence is signified by a definition, it is called quiddity or “whatness.” Quiddity is a term derived from the Latin word quidditas, which is the technical noun fashioned from quid (Latin for “what”). “The reason is obvious” observes Bittle. “When we desire to know what a particular thing really is, we ask the question ‘What is it?’ And in answer to this question we obtain a knowledge of its ‘whatness’; because, in being told what it is that makes this thing to be just this being and not another, we find out its essential elements (essence) in the definition given.”[218] 

 

A definition signifies the essence of something by means of its proximate genus and specific difference. It gives an answer to the question “What is it?” The definition of man, for example, would be “rational animal.” This is the metaphysical essence of man. “Animal” would be the proximate genus and “rationality” the specific difference that separates him from all other animals.

 

Essence as the Universal. Insofar as essence is known, it is possible for it to be referred to many individuals, and for this reason it is called the universal. “The essence is really present only in individual things. However, our understanding, setting aside the characteristics which belong to each singular thing, considers the essence as something universal, which can be attributed to all individuals having the same mode of being. In accordance with the way of being which the essence of this horse has in the human mind, it becomes a universal which is applicable to all horses. This logical consideration of the essence, that is, the essence as a universal, is what is called secondary substance.”[219]

 

Essence and Esse. Though capable of being utilized in these various senses, essence nevertheless stresses its relationship with esse, it being the principle in which the esse of a thing is received and by which it is restricted to a determinate form; essence is so called insofar as a thing has esse in it and through it. Thus, essence has a meaning over and above that contained in nature, quiddity, and universal as it directs our attention to that which makes things be, namely, the act of being (esse): “Essence means that through which and in which a being has its act of being (esse).”[220]  

 

Classification of Essences

 

Essence is either a physical essence or a metaphysical essence. In the case of man, for example, his physical essence consists in the hylomorphic composite of body and soul, while his metaphysical essence would be ‘rational animal.’ Why do we have two main kinds of essence? It is because essence can be viewed from two fundamentally different standpoints, namely: 1 from the standpoint of its concrete existence in the physical world (here we get the physical essence) and 2. from the standpoint of its abstract conception by the thinking mind (here we get the metaphysical essence). Physical essence is the essence existing concretely in nature, independent of cognition of it.[221] Metaphysical essence, on the other hand, consists in the sum of the various grades of being which constitute a thing in the abstract concepts of the human mind. Such ‘grades of being’ in a concrete nature are identical in reality and separable only in the human mind.[222]

   

The Essence of Material Beings

 

All corporeal substances are hylemorphic composites, that is, beings composed of matter and form. Every material or corporeal substance is an essentially single individual being compounded of two intrinsic essential principles, namely, prime matter and substantial form. In a material thing prime matter is potential, passive, and determinable, while the other co-principle, substantial form, is actualizing, determining and active. Prime matter in a material thing is the root of receptivity and passivity. Because of it, a body can be acted upon, moved, divided, changed, or corrupted. Because of the substantial form the material substance maintains its own identity, possesses its own properties, causes changes in other bodies, and makes itself known. By reason of the substantial form the body is of a certain nature, an individual member of a particular species. We may have ten pieces of chalk yet they have the same substantial form, the form of chalk, that is, the bodies of the same species have the same substantial form in different parcels of matter. Prime matter and substantial form are the two essential co-principles of the substance. Taken by themselves, they are incomplete substances, but taken together in the hylemorphic composite being they form one complete substance. Matter and form are the intrinsic causes of the substance. Prime matter is the receptive subject of the substantial form and embodies it in concrete being. Substantial form actualizes the matter, determining it to a specific nature. Form is the principle of nature or species while matter is the principle of individuation.[223] Matter is the principle which multiplies the forms. Aside from multiplying the forms, matter also individuates or singularizes it. It is matter, in which the form of the species is received, that makes the existence of many individuals of the same species possible.       

 

Norris Clarke on the Role of Essence Within St. Thomas’ Essence-Act of Being Doctrine

 

In an article published in 1974, Norris Clarke presents his theory on the nature of essence as a principle of limitation of the act of being. He does not side with what he calls the traditional interpretation of the nature of essence as a positive principle, the positive subject that receives the act of being but nevertheless limits it. Those supporters of what he calls the traditional ‘positive essence’ position, he writes, include Cornelio Fabro and Joseph Owens. Norris Clarke gives us the position of the traditional, orthodox ‘positive’ view of essence, which he calls the “thick essence” doctrine: “It conceives of essence as a positive receiving subject, given reality indeed by the act of existence[224] which actualizes it and pours into it its own perfection, but nonetheless constituted as a distinct positive subject which exercises the act of existence; it is the essence properly speaking which exists, is that which exists, although by means of, or through the power of, the act of existence.”[225] Norris Clarke disagrees with the traditional positive essence interpretation in favour of what he calls the ‘thin essence’ interpretation, espoused by thinkers like the late Gerald Phelan, and his disciple the late William Carlo, who “wonder if such a conception of essence as positive subject, distinct from the act of esse as a positive principle, is really consistent with St. Thomas’ own deepest intuition and his great texts on esse as the plenitude of all perfections and essence as in itself non-being.”[226] 

 

Then comes Norris Clarke’s defense of the ‘thin essence’ view opposing the orthodox interpretation: “If we take seriously that esse is the intensive plenitude of all perfections, it is hard to see how any act of esse can allow any positive principle as distinct from it in a composition, somehow making its own positive contribution. It is replied, of course, that the positivity of essence is itself constituted by the act of existence cojoined with it. But it is not clear how anything, even a metaphysical principle, can be distinct, really distinct, from that which constitutes it intrinsically in its most intimate positivity. It looks as though the very notion of ‘receiving subject,’ carried over from other contexts of form and matter, substance and accident, where it served well, here breaks through the bond even of proportional analogy and betrays the new insight it is attempting to serve. The new wine of esse as the intensive plenitude and core of all perfection cannot easily be poured into the old language of essence as subject and existence as predicate nor into the Platonic-Neoplatonic framework of perfection and receiving subject, nor even without severe stretching into the Aristotelian framework of act and potency, understood as positive potential subject.”[227] Here, in this position of Norris Clarke and company, the affirmation of the real, and not mental, distinction of two constitutive principles of being (ens) begins its gradual obfuscation, its process of alienation from the Angelic Doctor’s thinking: “it is not clear how anything, even a metaphysical principle, can be distinct, really distinct,…”[228]  Essence as a really distinct receiving principle is being gradually eliminated by this group.

 

Norris Clarke continues: “It would seem then, that the only kind of principle that the act of existence can tolerate in composition with it is an intrinsic principle of limitation only, that makes no positive contribution of its own but merely limits or ‘contracts,’ as St. Thomas says, what would otherwise be the de se plenitude of existence down to a particular limited mode or level or degree – so much of the perfection of esse and no more. All the perfection and positivity would thus be on the side of the act of existence; essence would provide only the intrinsic negative limiting principle, resulting in a limited mode of existence, or better, a limited act of existence, reflecting, of course, the limitation of His own perfection first thought up by God in a determinate divine idea of a possible imitation of His own infinite plenitude. That which exists in this conception would no longer properly be the essence as positive subject which would have existence, but rather the limited act of existence itself, which would be the subject. Finite beings would thus be finitized-acts-of-existence, not essences which have existence. The act of existence in any of its modes, whether that of infinite plenitude or some finitized mode, since it is the ultimate radical principle of concretion, immediately becomes a concrete subject in its own right, either eternally in God, who is nothing else but Pure Act of Existence and therefore pure Subject without anything needing to be added to it, or wherever some new limiting principle allows a new act of esse to be present distinct from the original Plenitude. Thus many limited acts of existence would be that which exists, each limited and distinguished from the other through its own intrinsic limiting principle of essence; not many finite essences which exist through their act of esse. The difference in expression is significant, not merely verbal. Essence thus conceived purely as an intrinsic principle of limitation, not itself a positive subject but that which permits a new finitized act of existence to become a new subject which exists distinct from all others, is what I might call the ‘thin essence,’ as opposed to the ‘thick’ one of the previous conception.”[229]

 

The advocates of essence ‘conceived purely as an intrinsic principle of limitation’ propose a serious departure from the thought of St. Thomas, which would compromise the intelligibility of his real distinction doctrine. In fact, Norris Clarke writes that the real composition doctrine of esse and essence is but a “secondary technical device for explaining the basic notion of limited participation in existence, which might possibly to replaced by more adequate technical devices…”[230] It seems here that Norris Clarke, having made unintelligible the real composition between act of being (which he wrongly calls the act of existence) and essence with the Phelan and Carlo inspired ‘thin essence’ theory, is drifting towards a mental, and not a real distinction, reminiscent of Suarez. Surely Phelan, Carlo, and Norris Clarke, with their emphasis on existence rather than essence, cannot be styled essentialists; rather they can be characterized as existentialists, advocating essence as ultimately reducible to existence. Sure enough, William Carlo’s book published in 1966, is entitled The Ultimate Reducibility of Essence to Existence in Existential Metaphysics.[231] Norris Clarke wrote the preface for this book. Elders criticises this existentialist ‘thin essence’ group, and I believe rightly so. He explains that, considering the fact that for Aquinas esse is the act of acts and the perfection of all perfections, the group of Norris Clarke, Phelan, and Carlo do not consider essence anymore as a principle of being with a proper positive content. For this group, essence becomes nothing but a limiting factor that contracts the act of being, a factor thanks to which the act of being is given a limited content. In such a perspective, essence is reduced to a sort of empty potency. Elders warns that this reduction of essence to a potency without a positive content would render the multiplicity and order of things unexplainable; it would rather depend upon the blind impulse of the act of being towards realization. The mutual causality between act of being and essence would be deprived of its significance.[232]

 

Defense of the Positive Reality of Essence

 

Defending the positive reality of essence, Phillips writes: “The obvious objection to the Thomist view of the real distinction between essence and esse” observes Phillips, “is that it is by esse and esse alone that a thing passes from being merely possible to being real, all its reality is due to esse, so that all the reality in an existing thing is esse. There is no distinct reality which is essence. But this difficulty is due to a confusion of thought, for the reality which esse confers on essence is certainly to make it really existing, so that the reality of really existing, in an existing thing, certainly is esse. It does not follow that all the reality in it is esse; there may, and in fact, must be some real subject of which esse is the act, otherwise what was and remained merely possible would exist and be real. Just as matter is a reality, though one which without form sinks into unreality, so essence is reality, though without esse it sinks to being merely possible. Matter is not real without form; but with it is not the same reality as form: essence is not real in the existential order without esse, and yet with it is not the same reality as esse. These two are indispensable, the one to the other; they are distinct, but not separable. What is not a real capacity for esse cannot receive the act of being, just as the act of being cannot actuate anything but a real capacity for receiving it. Essence, as it were, calls out for esse its correlative, so that we see the truth of the dicta ‘esse per se consequitur formam’ and ‘forma dat esse,’ since substance being defined by the power to be ‘in se,’ esse is the fulfilment of this power, the act of this potency; so that as St. Thomas sometimes says: ‘esse…is, as it were, constituted by the principles of essence,’[233] and so is not added to essence after the fashion of an accident.”[234] 

 


 

CHAPTER 7

 

ACT OF BEING (ESSE)

 

 

The principal element of being (ens) is its act of being (esse). The act of being (esse) is that which makes a thing to be.

 

The act of being (esse) is an act which is a perfection of all reality. In metaphysics, act refers not only to transient actions and immanent operations of an agent subject but designates any perfection of an individual being. Esse is a universal act for it is not an exclusive property of a particular type of being but is proper of all things that exist in reality. The act of being is a total act for it is a perfection that includes all that an individual being has and encompasses all that an individual being is. If essence is that which makes a thing to be this or that, esse is that which makes a thing to be. A thing is, not because of its essence, which is the principle of diversity, but because of its act of being which is the act common to all beings. The act of being precedes every other act as no action, property or agent subject would be without it. Actions and immanent operations like understanding and willing are accidents which presuppose a subsisting subject, but all presuppose esse for without esse nothing would be. Therefore, the act of being is the principal and innermost act of a being which gives the subject, from within the substantial being itself, each and every one of its perfections. Esse intrinsically actualizes every substantial being as it is their principle of reality.

 

The act of being is the most intensive act as it contains, in its pure state, all perfections. Creatures have varying degrees of perfections as they participate in the act of being according to their determinate essences. Individual beings possess esse in different degrees of intensity. Insects, for example, participate in the act of being in a much less intense way than say, a dog. A human person participates in the act of being in a much more intense way than a horse. God alone is Pure Act of Being, in whom act of being and essence are identified. Only God is All-Perfect, possessing the act of being in all its fullness and intensity, infinitely surpassing all the perfections of the entire created universe. God, Pure Act of Being, without potentiality whatsoever, is devoid of any imperfection and limitation. On the other hand, all created things possess a limited and less intense participated act of being, and the more imperfect they are, the lesser act of being do they participate in. Therefore, the diversity of perfections of creatures created by God (who alone is Pure Act of Being) have their foundation in the diverse ways of possessing esse, for the source of all an individual being’s perfection is its esse.

 

“To Be” Not Exactly the Same as “To Exist”

 

‘To be’ (esse) is not exactly the same as ‘to exist,’[235] as certain Scholastics maintain; esse expresses an act while ‘to exist’ merely indicates a thing’s facticity, that this something is really there before us. When I affirm, for example, that a horse exists I wish to indicate that this horse is real and not just a cognitional or intentional being, a mere idea in my mind. Esse, on the other hand, signifies something more interior, and not mere facticity, the fact of being there, in transsubjective reality; rather, esse signifies the innermost perfection of a thing, and the fount of all its other perfections. Esse, as was said before, is the act of acts and perfection of perfections. Existence is merely the effect of esse. ‘To be’ has an intensive usage that ‘to exist’ simply does not have. For example, I can affirm that a dog exists and that a man exists, but I cannot say that a man exists more than a dog. On the other hand, one can say that a man is more than a dog or a cat or a horse or a plant.[236]

 

“To consider esse as existence,” write Alvira, Clavell and Melendo, “is a logical consequence of identifying being (ens) with possible essence, separated from the act of being. There arise two worlds, so to speak: the ideal world made up of abstract essences or pure thought, and the world of realities enjoying factual existence. The latter is no more than a copy of the former, since it does not add anything to the ontological make-up of things. As Kant said, the notion of 100 real gilders does not in any way differ from the notion of 100 merely possible gilders.[237]

 

“The distinction between ideal or abstract essence on one hand, and real existence on the other, has given rise to serious repercussions in many important philosophical questions. In the domain of knowledge especially, this has led to the radical separation of human intelligence from the senses: essence would be the object of pure thought, whereas factual existence would constitute the object grasped by the senses (this gave rise to the equally wrong extreme positions of rationalism and empiricism or positivism; in the case of Leibniz, it gave rise to the opposition between ‘logical truths’ and ‘factual truths’).

 

“Another consequence of this view is the attempt to prove the existence of the First Cause starting from the idea of God (the ontological argument): God would be the only essence which includes existence among its attributes, and therefore, God should exist. This ‘proof’ ends up with a God which exists only in the mind.”[238] 

 

The Real Distinction between Essence and Act of Being

 

Those who deny that St. Thomas ever defended the real distinction between essence and act of being in finite beings include M. Chossat,[239] P. Descoqs,[240] and the Jesuit Francis Cunningham,[241] who work under the influence of Suarezian essentialism. However, Suarez himself admits that St. Thomas held the real distinction, which, in spite of this, he denies.   

 

The real distinction between essence (essentia) and act of being (esse) in finite creatures[242] is one of the central doctrines of St. Thomas, first sketched out by the Stagirite[243] and later developed and perfected by the Angelic Doctor. The act of being is necessarily really distinct from essence since act is really distinct from its potency which receives and limits it. 

 

Arguments in Support of the Real Distinction Between Essence and Act of Being (Esse) in Finite Beings

 

1. The Argument Based on the Limitation Found in Creatures. Every created being possesses the act of being in a partial manner both in extension, as it is not the only one, and in intensity of being, as its actuality is possessed in a limited manner. No creature possesses the perfections to the greatest possible degree. Therefore, no created being is identical with its esse but rather participates in the act of being in a limited way, its essence being the receptive potency that limits the act of being.     

 

2. The Argument Based on the Multiplicity of Creatures. The testimony of the senses reveal the obvious fact that there are a multitude of beings around us. This shows that created beings are composed of act of being and essence. Why? Because if something’s essence were its own act of being it would necessarily be one and simple. Esse is really multiplied in many individuals, but this would be impossible unless the act of being be united to a potency – the essence – really distinct from it.

 

Seeing that reality is manifestly multiple, made up of a multitude of beings, “St. Thomas argues that the esse of these many things cannot be really the same as their essence, since, if it were, they would not be multiple, but one and unique. For a being whose very essence is to be cannot be differentiated in any other way, and so cannot be multiple. Such a being would be its own subsisting act of being, for its esse is its actual substantial essence, its own substance. That it cannot be multiple is seen first from the fact that esse, being an act, can only be limited and multiplied by subjective potency. Now subsisting esse does not, by hypothesis, inhere in anything, and so cannot be received in any potency; nor can it have any potency in itself, i.e., any capacity for any other act, for this act could only be subsistence or existence, both of which it already possesses. Hence it cannot be multiplied, but must be unique. Secondly, subsisting esse is absolute perfection, since it is perfect both as a being and as a substance. Consequently it can be one only; for if there were two such absolute perfections one of them would have to posess some perfection which the other lacked, otherwise they would not be two, but one. That which lacks some perfection would plainly not be absolutely perfect, so that it is impossible that there should be two absolutely perfect beings.”[244]    

 

3. The Argument Based on the Similarity Found Among Beings. If two or more creatures are similar there must be something in them that accounts for their conformity and something that accounts for their difference. The source of their similarity must naturally be distinct from the source of diversity. Now, all creatures are similar because they possess the act of being, and because of this they all exist. But they differ from one another on account of their essences (essence is the principle of specification) which limit esse in diverse manners. Therefore, act of being and essence are really distinct from one another.   

 

4. The Argument from the Fact of Caused Being. “Finally the real distinction can be argued from the fact of caused being. Whatever is caused by another, the spiritual creature (angel), man, the material being of the cosmos precisely as caused by another, it receives esse by the action of an agent and so it cannot have esse by its own nature. A being whose essence is to be must be of its very nature and so it essentially or necessarily exists. It is impossible that it not exist. It cannot receive esse from another. It is simply uncaused. Whatever is caused being, therefore, is being whose essence is really distinct from its esse. St. Thomas says: ‘It is against the nature of a made thing for its essence to be its act of being…’[245][246]

 

“This way of arguing to the real distinction of essence and esse in creatures,” writes Dougherty, “proceeds from the very nature of the creatures themselves.[247] Inasmuch as they are caused by another, they are given esse by another, and so cannot have it of themselves, of their own nature. For that whose essence is to be, exists of its very nature and so essentially and necessarily. This being so, it is impossible that it should not exist. Existing of itself cannot receive esse from another, and so cannot be caused. Consequently in things which are in reality caused, esse must in reality be distinct from their actual essence. So, as St. Thomas says, ‘It is against the nature of a made thing for its essence to be its act of being; because subsisting being is not a created being.’[248][249]

 

A General Argument Showing the Real Distinction. “These arguments,” explains Dougherty, “may be summed up in a general argument. If a being exists so that its essence is its esse, such a being would be pure actuality. It would possess no potency since the act of being completes a thing as its ultimate perfection. A being whose essence is its esse would be essentially actual or absolutely perfect. A finite or created being by identity cannot be absolutely perfect. Therefore, its essence cannot be really identical with its esse. Essence and act of being in finite beings must be really distinct. As we have seen, every finite being must have potency as its coprinciple with act in being, precisely because it is limited, composite, mutable and caused.”[250] 

 

Phillips explains that “if the esse of any being were not really distinguished from the essence of this being, such esse would be pure act, for it could neither be received in any potency nor contain any potency in itself; in the Scholastic phrase, it would be unreceived and unreceiving act. This esse could not be received in any potency, since being really the same as the essence, there would, in fact, be nothing in such a being except esse; and so nothing for esse to be received in. Nor could it receive any further act, and so be itself potential with regard to it; for it is plain that esse is the act which completes the thing as a real being, so that once the thing is there is no further perfection which can be added to it as a being. The esse, then, of such a being, and so the whole being, since it is esse, would be pure act. A finite or created thing, cannot, however, be pure act, since pure act containing no potency or imperfection, must be altogether perfect and unlimited or infinite, for potency alone limits act. So if we look at the question from the point of view of finite being we see that such a being cannot be pure act, from which it follows that its essence and act of being must be really distinguished, since that being in which they are identified will be pure act.”[251] 

 

A Short History of the Real Distinction between Essence and Act of Being

 

Aristotle first laid the groundwork for the real distinction in the Posterior Analytics, though a developed doctrine is nowhere to be found in his writings. The Stagirite’s doctrine of act and potency offered a basis for the real distinction, but it is clear that his doctrine did not teach that all the perfections of the subject, including the subject, were in potency to the act of being, the act of acts and the perfection of perfections. Plato suggests the real distinction in his doctrine of participation, but it remains just that, a suggestion which was to be developed later on by the Neoplatonists, the head of whom being Plotinus who taught that all beings, with the exception of God, had composition. Augustine teaches that God is Being by Essence, whereas creatures are beings by participation and can therefore be included among the list of those affirming the real distinction. Pseudo-Dionysius the Areopagite, with his participation theory, should also be included in the list of the defenders of the real distinction. Boethius holds a real distinction between esse and id quod est, but his esse is clearly not the act of being but rather second substance, the id quod est, in contrast, being the first substance of Aristotle. Therefore he does not give any existential meaning to esse and thus does not, in the final analysis, teach the real distinction between esse and essence. Al-Farabi and Avicenna both taught the real distinction, but for Avicenna, esse is understood to be a kind of accident to the essence. Averroes, and later St. Thomas, criticized this interpretation. William of Auvergne, St. Albert the Great, and St. Bonaventure, all taught the real distinction, but it was Aquinas who perfected the doctrine. There is no doubt that St. Thomas held the real distinction of essence and act of being in finite creatures, as well as the identity of essence and act of being in God. To deny the real distinction would make Aquinas’ doctrine of essence and act of being simply unintelligible. Aegidius Romanus, or Giles of Rome, defended the real distinction, but in such a weak way, erroneously teaching that essence and act of being were really distinct like two things (distinguuntur ut res et res), that his views were rejected and attacked by Henry of Ghent who denied the real distinction. Others denying the real distinction include Averroes, Siger of Brabant, and the Latin Averroists. Duns Scotus, William of Ockham, and the famous Jesuit metaphysician Francisco Suarez also denied the real distinction, all being influenced by Henry of Ghent. Suarez denied the real distinction in favour of a virtual distinction.[252] Also rejecting the views of the Dominican Aquinas on the real distinction were fellow Dominicans Durand de Saint Pourçain and James of Metz. Certain Jesuits, who do not follow the lead of Suarez and defend the real distinction include Schiffini, Billot, Mattiussi, Remer, Maurice de la Taille, Boyer, and Henri Renard. Most of the early Thomists defended the real distinction including Capreolus and Francis de Sylvestris.


 

 

CHAPTER 8

              

THE SUPPOSIT AND THE PERSON

 

 

Supposit: Being in the Fullest Sense

 

A consideration of the various constitutive principles of being should naturally have as its goal being in the fullest sense, which is the supposit, our subsisting subject. The term subsisting subject refers to the particular being with all of its perfections. The supposit or subsisting subject is being in the full sense; it is being in the most proper sense of the term, subsisting, existing in itself as something complete and finished, distinct from all other things. The supposit designates the particular being with all of its perfections. The supposit is defined as the individual whole, which subsists by virtue of a single esse, and which consequently cannot be shared with another.

 

Characteristic Marks of the Supposit

 

The characteristic marks of the supposit are its individuality (only the singular exists in transsubjective reality while the universal exists in the mind; abstract essences cannot be suppositums for they do not have esse of its own), subsistence (we must add subsistence for not everything that can be called individual can subsist; accidents are individual but are not subsistent), and incommunicability or unsharedness (because of the preceding two characteristics, namely, individuality and subsistence, the suppositum cannot be shared by others. The suppositum cannot be participated in by various subjects for it exists as something unique and distinct from other subjects. A rock, for example, does not share its being with the book that is next to it).

 

Elements of the Supposit

 

What are the elements that make up the supposit? The subsisting subject (suppositum) is composed of act of being (esse, which renders subsistence to the subject, making it be), essence (essentia, which in corporeal beings are hylomorphically composed of prime matter and substantial form), and accidents (which are acts that perfect the receptive subject in potency to be perfected by them). The various names that have designated it throughout the history of philosophy include the whole, the concrete, the singular, the individual, the supposit or hypostasis, and the Aristotelian first substance (primary substance), that  individual something which exists in reality with all of its perfections.

 

Supposit and Nature

 

There is a difference between supposit and nature. The supposit is really distinct from its nature in finite beings in the same way that a whole is different from one of its parts. There is a real distinction between supposit and nature in any being to which something can be added which does not belong to its very nature. In any finite being, at least its act of being (esse) itself does not belong to its very nature. Thus, it follows that in every finite being there be a real distinction between supposit and nature. When we speak of real distinction here we don’t mean that the supposit is one thing and the nature another thing. The real distinction in question is not adequate but inadequate, inasmuch as the supposit includes the individual nature and adds a reality to it. St. Thomas writes: “In every thing to which can accede something which does not belong to the concept of its nature, the thing itself and its essence, i.e., the supposit and nature, are distinct. For, in the meaning of the nature is included only that which belongs to the essence of the species, whereas the supposit has not only what belongs to the essence of the species but also whatever else accedes to this essence. Hence, the supposit is signified by the whole, but the nature or quiddity [is signified only] as the formal part. Now, in God alone no accident can be found added to the essence because His act of being is His Essence, as has been said; hence in God supposit and nature are entirely the same. But in an angel [i.e., an unreceived subsistent form] the supposit is not entirely the same [as the nature] because something accedes to it which does not belong to the concept of its essence. For the act of being itself of an angel is in addition to the essence or nature; and other things [acts of intellect and will] accede to it, which belong to the supposit but not to the nature.”[253] 

 

Alvira, Clavell and Melendo explain that the “essence, and more particularly the form, gives the individual whole a way of being similar to that of other individuals, thus situating it in a given species. Due to a common essence or nature, men form part of the human race or species. As the intrinsic principle of similarity at the level of the species, the essence can be contrasted with the supposit or individual, which is an unshared reality (distinct and divided from all others). Consequently, the relation between supposit and its nature is not that which exists between two principles of being; rather, it is one that entails a real distinction; the supposit is distinct from its nature in the same way a whole is different from one of its parts.[254] The real distinction between nature and supposit can be seen in two ways: a) in every individual, there is a distinction between the individuated essence and the whole subsisting subject; b) every individual is distinct from the common specific nature (taken as a universal perfection which all individuals share, and which sets aside particular characteristics).”[255] 

 

In this treatment of the distinction between supposit and nature, Renard explains that “the supposit does add something not contained in the nature. It includes everything, says everything that can be predicated of a being. The nature on the contrary in creatures is distinct from and consequently does not contain its ‘to be’ (esse) and its accidents. ‘These words: person, hypostasis, and supposit designate an integral being.’[256] A human supposit ‘is the entire being that is this man.’[257] ‘The supposit implies that which is most complete.’[258] Therefore, it takes in the accidents whereas the nature does not. Consequently, the nature is part of the supposit, a part which is designated as the formal part.[259]

 

“Moreover, since the ‘to be’ (esse) is the highest actuality in the order of being, and the supposit demands the most perfect completeness in that order, it follows that the substantial ‘to be’ (esse) by which a being subsists is of the very essence of the supposit. It is not the supposit itself, for the supposit includes the whole being; but we may say that it is its most important factor: for it is that because of which and by which a being attains its highest completion in the order of being, and by which it exists in its own right (it subsists). ‘The to be (esse) is that in which the unity of the supposit is founded.’[260] ‘The to be (esse) pertains to the very constitution of person.’[261] ‘Person signifies that which is most perfect in the entire nature, namely, a being subsisting in a rational nature.’[262] It must include, therefore, the ‘to be’ (esse) which is ‘the actuality of all acts, and the perfection of all perfections.’[263] Indeed the most perfect completion consists precisely in this, that a being has its ‘to be’ (esse), which is an analogous participation in the divine ‘to be’ (Esse).’[264]

 

“To repeat then – the individual nature differs from the specific nature in that it adds to the latter the individuating principles (in actu secundo); the supposit differs from the individual nature in that it adds the ‘to be’ (esse) and the necessary concomitant accidents.

 

The Supposit Adds the Proper ‘To Be’ (Esse) to Individual Nature. It is, therefore, this substantial ‘to be’ – the very act of esse (which ‘to be’ is proportioned and due to each individual nature) – that conjoins with the nature to establish the supposit and render it incommunicable in an absolute sense. Thus the supposit is established by the very act of coming into existence. Let us analyze this last statement. Since the supposit demands perfect completion, and since the highest completion in a being consists precisely in the actuation in the order of being by a ‘to be’ (esse) that is proportioned to its individual nature, that is to say, by a proper ‘to be’ (esse), it follows that an individual nature with its ‘to be’ will establish a supposit. In other words, the supposit adds to an individual nature its proper ‘to be’ (esse).”[265]

 

Act of Being as the Source of Unity of the Supposit

 

Alvira, Clavell and Melendo explain that the act of being (esse) belongs to the suppositum and that the source of the unity of the suppositum lies in its proper act of being (esse): “The constituent act which makes the suppositum real is esse. What is most proper to the individual is to subsist, and this is solely an effect of the act of being.[266] Nevertheless, one cannot disregard the essence in explaining the subsistence of a subject, since a being receives esse if it has an essence capable of subsisting; that is, it must be a substantial essence, not a mere accidental one. For instance, as man is able to receive the act of being in himself and to be a suppositum because he possesses human nature, an essence meant to subsist in itself (and, thus, not to inhere in something else, as in the case of accidents).

 

“However, the specific nature of a thing does not subsist unless it forms part of a subsisting subject (the individual). That is why it is not quite correct to say that the act of being belongs to the nature; it only belongs to the suppositum. However, since esse affects the whole by virtue of the essence, we can say that ‘esse’ belongs to the suppositum through the nature or substantial essence. Nature gives the whole the capacity to subsist, although it is the whole which does in fact subsist through the act of being.

 

“Since esse is the ultimate act of a being, which gives actuality to each of its elements (which are no more than potency with respect to esse), these parts are united to the extent that they are made actual by this constituent act, and referred to it. It is quite correct, therefore, to claim that ‘the act of being is the basis of the unity of the suppositum.’[267] No part of the whole, taken separately, has esse of its own; it is, by virtue of the esse of the composite. To the very extent that the parts of the whole have esse, they must be a unity, since there is only a single act of being that actualizes them. Matter, for instance, does not subsist independently of the form; rather, both matter and form subsist by virtue of the act of being received in them. Operations are no more than an expression of the actuality which a being has because of its esse, and the same thing can be said of the other accidental modifications as well. In spite of the variety of accidents, the unity of the suppositum can easily be seen if we consider that no accident has an act of being of its own. All accidents share in the single act of being of the substance.”[268]

 

Perfections of a Particular Being to be Referred to the Supposit

 

Alvira, Clavell and Melendo also explain why all the perfections of a particular being must be referred to the suppositum: “We have seen that the entire actuality of a being has its ultimate basis in the perfection of its act of being. Since the suppositum is the natural seat of the act of being, all the perfections of the suppositum, of whatever type they might be, have to be attributed to the suppositum as their proper subject. Actions, in particular, have to be attributed to the subsisting subject. Thus, it cannot correctly be said that the hand writes, that the intellect knows, or that the will loves. In each case, it is the entire man who acts through his powers. Only that which subsists can act.

 

“It could be further stated that the manner in which an individual acts follows its nature, which is what determines its manner of being. It can, therefore, be claimed that acting belongs to the subsisting hypostasis in accordance with the form and nature specifying the kind of operations it can carry out. Thus, only individuals act, since they alone exist. There is a certain similarity, however, among the activities of the members of a species, since all of them share in a common nature. Men think and laugh; dogs bark; each one of the elements of the periodic table behaves in a particular way. This also explains why no individual can act beyond the limits set by its own species.

 

“The recognition of the individual as a single subsisting whole provides the metaphysical basis for avoiding any kind of dualism (between matter and spirit, between senses and intelligence) and any division of things into stagnant compartments in which the unity of the whole would be compromised.

 

“This doctrine equally denies the validity of philosophies which acknowledge the universal as the primary reality (like in Hegelian historicism, socialism, and marxism), thereby absorbing the individual, robbing it of its metaphysical significance. The actus essendi, as the single act of the suppositum, impedes any reduction of being to a mere relation or to a set of relations within the same class or category, as these philosophical systems purport to do.”[269]

 

Subsistence

 

Subsistence is the perfection by which the individual complete substance becomes a supposit. In the case of the rational supposit, the person, this perfection is called suppositality. This perfection makes the individual complete substance entirely incommunicable and intrinsically (not extrinsically) self-sufficient.[270]

 

Person

 

Man is a particular type of supposit, namely, a rational supposit. Rational supposits are called persons. A human being, therefore, is a person. The sixth century A.D. Roman philosopher Severinus Boethius was the first thinker to formulate an adequate definition of the person as an individual substance of a rational nature (individua substantia rationalis naturae). The most perfect beings that exist are persons, namely, God (who is Pure Act of Being), as well as angels (also called the separate substances) and men (both angels and men having particularly intense degrees of participation in esse). “Since all perfections stem from esse, the excellence of these substances (God, angels and men) is due either to the possession of the fullness of the act of being (God as Esse Subsistens), or to a high degree of participation in esse which angels and men have. In the final analysis, to be a person amounts to possessing a likeness of the divine esse in a more sublime way, that is, by being spiritual; it means having a more intense act of being…ultimately, the entire dignity of the person, the special greater perfection of his operations, is rooted in the richness of his act of being. The latter is what makes him a person and provides the basis of his psychological uniqueness (self-knowledge, spiritual love, etc.) and of his moral and social value. Consequently, neither consciousness nor free-will, neither responsibility nor inter-personal relations can constitute a person. All these perfections are merely accidents whose being is derived from the act of being, the only real core of personality.”[271]

[24] St. Thomas Aquinas, in his commentary on the Metaphysics of Aristotle, writes of the science of metaphysics: “First, in contrast to other sciences, which explore only the more immediate principles and causes, metaphysics stands forth as the science of first causes and first principles. This definition echoes the general notion of science, for in the Aristotelian tradition it is axiomatic that science, all true science, consists in knowledge through causes: cognitio per causas. It is from this point of view that metaphysics is properly called “first philosophy,” the conception that predominates in Book A of Aristotle’s treatise. Secondly, metaphysics can also be envisioned as the science of being as being and of the attributes (or properties) of being as being, a view of the science which points to the comprehensiveness of its object. Unlike other sciences, each of which considers only a particular province of being, metaphysics, the science of being as being, embraces all being. This conception is developed in Book Γ and appears to be upheld in the sequel. It is the conception which corresponds to the word “metaphysics” in its proper sense. Thirdly, metaphysics can be defined as the science of the immobile (i.e the motionless or unchanging) and the separate (i.e. from matter). In this it differs from the philosophy of nature or physics in the Aristotelian sense and from mathematics; for the proper object of these sciences always retains some mode of materiality. Moreover, among beings that are separate (i.e. free) from matter must be reckoned God, who is indeed furthest removed. Consequently, metaphysics understood as the science of the separate includes the study of God and is not improperly spoken of as “theology,” the conception that preponderates in Book E and thereafter”(ST. T. AQUINAS, In Metaph., Prooemium). The “theology” of which Aquinas is speaking here is not sacred theology based upon Divine Revelation, but rather, natural theology or philosophy of God, which is the highest branch of metaphysics.  According to St. Thomas, metaphysics is the first among the sciences (of course, the science based on human reason alone), governing and directing them, in virtue of the principle that the most intellectual science is the ruling or governing science. Metaphysics is the most “intellectual” science since her object regards the most intelligibles, beings and the modes of being of the highest intelligibilty. Aquinas then explains in his commentary that the concept “most intelligible” admits of a threefold meaning, from which clings our threefold conception: “First, [“most intelligible” can be understood] from the viewpoint of the order of knowing; for those things from which the intellect derives certitude seem to be more intelligible. Therefore, since the certitude of science is acquired by the intellect knowing causes, a knowledge of causes seems to be intellectual in the highest degree. Hence that science which considers first causes also seems to be the ruler of the others in the highest degree. Second, this phrase can be understood by comparing the intellect with the senses; for while sensory perception is a knowledge of particulars, the intellect seems to differ from sense by reason of the fact that it comprehends universals. Hence that science is pre-eminently intellectual which deals with the most universal principles. These principles are being and those things which naturally accompany being, such as unity and plurality, potency and act. Now such principles should not remain entirely undetermined, since with them a complete knowledge of the principles which are proper to any genus or species cannot be had. Nor again should they be dealt with in any one particular science, for, since a knowledge of each class of beings stands in need of these principles, they would with equal reason be investigated in every particular science. It follows, then, that such principles be treated by one common science, which, since it is intellectual in the highest degree, will govern the others. Third. This phrase can be understood from the viewpoint of the intellect’s own knowledge. For since each thing has intellective power by virtue of being free from matter, those things must be intelligible in the highest degree which are altogether separate from matter…Now those things are separate from matter in the highest degree which abstract not only from signate matter…but from sensible matter altogether; and these are separate from matter not only in their intelligible constitution [ratio], as the objects of mathematics, but also in being, as God and the intelligences [spirits]. Therefore the science which considers such things seems to be the most intellectual and the ruler and master of the others”(ST. T. AQUINAS, op. cit. Prooemium).

     Metaphysics operates at the third degree of abstraction, not at the first degree which is proper to physics and the natural sciences (where physical concepts indicate aspects that are in sensible matter and are understood in that matter, where abstraction regards solely from the individual matter), nor at the second degree which is proper to mathematics (where mathematical concepts abstract from observable aspects, indicating quantitative structures in abstract). In the third degree proper to metaphysics, metaphysical concepts correspond to certain aspects of things understood without sensible matter, and which are also encountered in immaterial beings. St. Thomas writes that “there are some things whose being depends on matter, and which cannot even be defined without matter; others, instead, although they cannot exist outside of sensible matter, are defined without reference to the sensible matter (…) Others, finally, do not depend on matter, either with respect to being or with respect to the human understanding, or because they are never in matter, such as God and the other spiritual substances, or because they are not always in matter, such as substance, act and potency, or being itself. Metaphysics considers these realities; mathematics occupies itself with those that depend on matter insofar as beings, but not insofar as their being understood; physics considers those that depend on matter both in being and in the understanding” (ST. T. AQUINAS, In Phys., lecture 1. Cf. In Boeth. de Trin., II, q. 1, a. 1).

     The three degrees of abstraction (of which metaphysics is the third) are called degrees of abstraction in the sense of a progressive elevation above matter. For Aquinas, the first two are types of abstraction, but he prefers to call the third operation “separation.” The reason for this terminology, writes Juan Jose Sanguineti, “seems to be the detachment from Platonism. For Plato, all that is mentally separable (abstraction) exists separated from the matter (confusion between abstraction, which is a mental separation, and true and real separation). For Aristotle and for Saint Thomas metaphysics, in its inquiry on the separated (spiritual) substances, must not follow the conceptualistic method of separating the essences, but must attempt a real judgment, in which it is separated (or is united) that which in reality is separated or is united, conforming to certain criteria of real separability (for example, the criterion of spirituality)”(J. J. SANGUINETI, Logic and Gnoseology, Urbaniana University Press, Rome, 1988, p. 331).

Logic is equally as universal in its scope as metaphysics, for ‘all beings fall under the consideration of reason’(IV Metaphys., 4, 547). But logic and metaphysics differ primarily in this, that while it pertains to metaphysics to consider every and any being, precisely as existing, actually or possibly, it is the office of logic to treat of any and every being, precisely as known or as knowable, i.e., as existing in the reason actually or possibly” (J.

[37] In I Physic., lect. 1. “Many authors affirm that the three degrees of immateriality represent different degrees of abstraction. However, in In Boeth de Trin., q. 5, a. 3, St. Thomas says that only the physical and mathematical degrees of immateriality correspond to different types of abstraction (taking abstraction to mean a mental separation); metaphysical concepts involve a real separation, in the sense that they are the result of separating from matter what is really separable or separated from it. At any rate, there is no objection to regarding the third degree of immateriality as the result of abstraction, provided we do not take abstraction to mean grasping partial aspects of reality (as is the case with the particular sciences), but rather transcending materiality”(J. J. SANGUINETI, Logic, Sinag-Tala, Manila, 1992, p. 199).

[79] De Torre writes: “Ens is that which has the act of being (in Latin: ens est id quod habet esse). There may be something which does not actually exist but is only a possibility, but then it is not an ens since it does not have the act of being; it is only an essence or ‘possibility of being.’ Ens, therefore, is an essence (or manner of being) which has the act of being: id quod est or id quod habet esse.

     “This shows that ens is composite, not simple. It has a composition of (a) subject of the act of being, and (b) act of being. The former is the thing that is; the ‘act of being’  is reality, not just a mere possibility. The two aspects are not the same, because to be is one thing, and the manner of being is another. This composition is such that the esse (to be) is contracted or limited by the essence or manner of being; the ens is only what it can be, that is, its essence: it is not everything, but only this type of being, this essence.

     “We can say that while essence is that which the thing is, esse is that by which the thing is. Esse, therefore, is a metaphysical real component or constituent part of the singular concrete being. It is not something that we grasp as a notion itself, because then it would be a noun. It is not a ‘thing,’ but that by which any thing is. It is the actuality of things, as distinct from their possibility. This is why we should not confuse our concepts (abstract essences) with reality or actuality”(J. DE TORRE, Christian Philosophy, Sinag-Tala, Manila, 1980, p. 76). 

[80] “Being is a real and intelligible principle, and the knowledge of its reality cannot be separated from the knowledge of its intelligibility. This dissociation has been carried out in formalistic scholasticism which speaks of ‘the distinction between essence and existence,’ instead of the genuinely metaphysical theory of the real composition of essence and act of being. The former distinction is made between between actual existence, considered as mere facticity, and the essence considered merely as possible. Essence and existence are, then, no more than two different states of mind with respect to the same thing considered respectively as a possibility, and as actually existing. Existence, in this case, does no more than add the concrete and irrational character of the fact to the abstract and intelligible notes of the essence. Some scholastics even ended up speaking about a distinction between the esse essentiae, and the esse actualis existentiae, which corresponds to a merely logical starting point (as a reply to the question ‘what is a thing’ – quid est – and ‘if a thing is’ – an est – ), but this is a starting point without any metaphysical dimension.

     “The real distinction between essence and act of being is not to be identified with the couple to be thoughtto really be. The authentic real composition of essentiaesse is not the formal nexus of two modes of a being, but rather the structuring of two real co-principles which make up the primary reality of being.

     “This composition is the transcendental structure of reality, which occurs in all finite beings inasmuch as they are beings. This composition of essence and act of being (esse) is real: they are really distinct metaphysical principles which constitute the radical unum which is being. It is necessary to admit this composition as real (and not only ‘cum fundamento in re’), because finite things are, but they are not the act of being (esse), they do not exhaust being (esse) either in intensity or in extension. They are, but without being being (esse): they have being (esse), they participate in being (esse). The participating principle (the potency: essence) cannot be really identified with that which is participated (the act: being – esse). If essence and esse were identified, the real principle of limitation (imperfection) would be the same as the real principle of perfection, which would violate the principle of non-contradiction. There would be no proper explanation for the real existence of finite beings: we would be denying either their reality or their finiteness”(A. LLANO, op. cit., pp. 116-117).

[82] T. ALVIRA, L. CLAVELL, T. MELENDO, Metaphysics, Sinag-Tala, Manila, 1991, p. 29. Owens writes: “Since it is the whole, the genus contains its differentiae implicitly and indeterminately. It is the whole conceived as undetermined by any of its specific differentiae. Each differentia is likewise the whole thing, now conceived as determining itself to its specific nature. Genus and differentia unite therefore in the species as whole with whole. But the genus may also be considered as the subject that is determined by the differentia. Their relation then is no longer that of whole to whole, but of subject to quality. Regarded in this way, the differentiae lie outside their genus and are not contained by it.

     “As one ascends through ever wider predicates of a thing, one finally comes to the widest predicate of all, being. It can be predicated in one way or another of everything. Is it therefore a genus, the highest genus of all? Genera, as has been seen, are established by abstraction, which is cognition in the order of simple apprehension. Being, on the contrary, is not known originally through simple apprehension but through judgment. Unlike a genus, it is not first reached by abstraction, even though it may later be conceptualized not only in the concrete but also in the abstract. Moreover, a genus does not contain its differentiae insofar as they are its specific qualities. But being does contain all its differentiae even in their determining function. If they did not exist they could not determine. Unlike a genus, consequently, being does not have a content in inverse ratio to its extension. Since in its own way it contains all differentiating notes, it has the richest content as well as the widest range.

     “Common being, therefore, is not a generic concept. Ratherm it is super-generic. It is above all the supreme generam and unites them all in its embrace. Conceptualized in the concrete, it is predicated of them all, for everything is a being. As an act, it is predicated even of its own differentiae in their qualitative aspect, for to differentiate they have to exist. It is the most common predicate of all”(J. OWENS, op. cit., pp. 64-65).

[92] Explaining the analogy of attribution and the analogy of proportionality, Wallace writes: “(1) In the analogy of  attribution, which is sometimes referred to as two- or three-term analogy, a perfection is predicated of each analogate, but one analogate is primary with respect to the other(s), and the perfection of the primary is attributed to the others by virtue of some relationship to the primary, usually that of causality. If the perfection is predicated properly and intrinsically of only the primary analogate and not of the other(s), the analogy is called extrinsic attribution; an example would be ‘healthy’ as said of man and then attributed to other subjects because of some causal relationship to health in man, e.g., healthy food, healthy exercise, etc. If the perfection is predicated properly and intrinsically of all analogates, on the other hand, even though one is primary, the analogy is called intrinsic attribution; an example would be ‘is’ or being as attributed to substance and accident, for here the being that is primary in substance is predicated properly of accident as dependent upon such substantial being. (2) The analogy of proportionality, sometimes spoken of as four-term analogy, usually takes the form of a proportion (schematically A:B::C:D) stating that a perfection found in one analogate is similarly but proportionately found in another analogate. If the perfection is really extrinsic to one of the analogates, the analogy is said to be one of improper proportionality; an example would be the metaphor of calling a king a ‘lion’ because the courage in the king is similar to the corresponding quality in the lion. If the perfection is found properly and intrinsically in both analogates, on the other hand, the analogy is called proper proportionality; an example would be the proportion, ‘as vision is to the power of sight, so simple apprehension is to the power of intellect.’ Similarly, one could say, ‘as substance is to its being, so accidents are to their being.’ As can be seen from the latter example, the analogy of proper proportionality can be very similar to that of intrinsic attribution. The difference is that in proper proportionality no direct relationship of dependence between the two analogates need be expressed, and so neither need be seen as primary with respect to the other or defined in terms of it, whereas in the case of intrinsic attribution such a relationship is explicitly recognized. Both types have important applications in natural theology”(W. WALLACE, op. cit., pp. 89-90).

[96] When we say “analogate” we mean “that of which an analogous term is predicated.” The term “primary analogate” means the analogate to which a term belongs principally, while the “secondary analogate” would mean the analogate of which such a term is predicated in dependence upon the primary analogate. If, for example, I predicate “healthy” of man, climate, food and medicine, man would be the primary analogate, while climate, food and medicine would be the secondary analogates. This example deals with the so-called extrinsic analogy of attribution.

[121] Koren: “The expressions ‘analytic principle’ and ‘analytic proposition’ should not be misunderstood. In Kantian philosophy a proposition is analytic if the predicate is contained in the essence of the subject; hence an analytic proposition is purely explicative. In Thomistic philosophy, a proposition is analytic if there is a necessary relation between the subject and the predicate. Thus the proposition ‘man is capable of speech’ will not be analytic according to Kant, whereas in Thomistic terminology it may be called analytic”(H. J. KOREN, op.cit., pp. 58-59).

[146] In this line we find the absolute Kantian distinction between phenomenon and noumenon (Kant carries out a logical-transcendental analysis of substance and accidents, limited to the knowledge of the phenomenal). In the Kantian theory of the object there is no place for the constitutive reference from what appears, to what is. There is an irreparable rupture between these two dimensions. But the truth is that being and phenomenon are fundamentally correlated; there is an essential homogeneity between that-which-manifests-itself and that-which-is-manifested. Being shows itself in the phenomenon, which is nothing other than ‘being-for-us.’ The phenomenon is a dimension of being, through which being becomes evident. The phenomenon is nothing other than the limited manifestation of being to a knowing subject (Cf. A. LLANO, Fenómeno y trascendencia en Kant, EUNSA, Pamplona, 1973, pp. 274-275).

[155] Ibid. “The essence of quantity consists in internal extension. For the external extension of a body is consequent upon its internal extension; a body cannot have parts in a place unless it have parts in itself; therefore, internal extension and not external extension is the root and essence of quantity. Now, while the essence of quantity (which is an accident) is found in internal extension, the essence of the quantified substance (that is, of the body which has quantity) is not constituted by extension, internal or external. Indeed, the essence of bodily substance is, in itself, independent of extension (for it is, in itself, integrally one and non-composed), although it has a natural requirement for extension; extension is a condition required for the natural existence of a body in the world of actual substances. When the body actually exists in the natural way, it has internal extension; it has integral parts which are parts of itself; the bodily substance itself constitutes these parts (that is, the parts consist of the substance), and this is saying that the substance itself is the formal cause of its integral parts.

     “In the world around us, we see that bodies have external as well as internal extension. External extension renders bodies impenetrable, mensurable, divisible, and determines their location. Now, as we have noticed, external extension is a secondary effect of quantity; a body must have internal quantity in the first place or it cannot be externally extended in the second place. But it is at least conceivable that the secondary effects of quantity might be prevented or removed without destroying the actuality or the primary effects of quantity in its essence. In other words, a body might conceivably exist with its internal extension (that is, its internal quantity) even if it had no external extension. Nature, of course, offers us no instances of such a thing, and our natural knowledge of bodies is always bound up with their external extension. But reason sees no contradiction, no impossibility, in the existence of a bodily substance without external extension. Philosophy has nothing further to say on the point; it merely indicates the truth that such an existence is not intrinsically impossible or unthinkable. Implicitly, philosophy concludes that, if a bodily substance is to have existence and internal quantity without external extension, more than natural power or forces will be required to give it actuality. For purposes of illustration we may borrow from our Faith an actual example of the thing of which we are speaking. In the Blessed Sacrament, Christ is present, – not only as God, but as Man with His true Body. The Body of Christ in the Eucharist has actuality; it has integral parts internally extended; that is, the Body has internal extension or quantity. But the Body has no external extension or quantity. The parts of the Body are not codimensional with corresponding external parts of the host; we cannot say that part of Christ’s body is in one part of the host, and another part of the Body in another part of the host, and so on. Nor can we say that the Body is dwarfed, or held in miniature, within the actual external dimensions of the host. Nor can the Body of Christ be locally confined by the quantity of the host, nor measured or divided with the measurements or divisions of the host. The entire Body of Our Lord is present (in mature and perfect being) in each host and in each part of each host. In the Eucharist, the secondary effect of quantity, – that is, external extension, – is blocked out by supernatural power, and the Body of Christ, with its true internal quantity, is here present without external extension or external quantity. It is plain, then, that the essence of quantity lies in internal extension, and that the actual extension of a bodily substance in a place is a secondary effect of quantity and not its essential expression”(P. GLENN, op. cit., pp. 63-65).  

[156] “Quantity as corporeal is either a matter of size or a matter of number. Quantity of size is called continuous quantity; its parts are united; the line which marks the end of one part is the same identical line which marks the beginning of the next neighboring part. By reason of this quantity a body is said to have magnitude, size, bulk. Quantity of number is called discrete quantity; its parts are severed, discrete, separated. These parts may be, indeed, more or less perfectly contiguous (one lying close to another, so that the line which marks the end of one part is right against the line which marks the beginning of the next neighboring part), but they are not continuous. The quantity of a grain of sugar is quantity of size, continuous quantity; but the quantity of a pound of sugar in a sack (the whole being regarded as one quantity) is discrete quantity; it is the quantity of a number of grains taken together. Other examples of continuous quantity: an apple, a horse, a man, a tree, a stone. Examples of discrete quantity: a peck of apples, a herd of horses, a group of men, a clump of trees, a pile of stones. Of the first examples we say that they are of such and such size; of the others, we say that they exist in such and such number (or multitude)”(P. GLENN, op. cit., pp. 258-259).

[163]Single Motion in Agent and Patient. There is but one single motion involved which is at once the foundation in reality for both action and passion. This does not occasion any difficulty since the single motion can be viewed from two distinct formalities, as that from which the motion arises (action) and that in which it terminates (passion). This difference is sufficient to separate the two predicaments of action and passion. Hence St. Thomas notes: ‘Although movement is the common act of mover and moved, yet it is one operation to cause movement and another to receive movement; hence we have two predicaments: action and passion’(De Potentia Dei, q. 7, a. 9, c.). If there is but a single motion involved as arising in the agent and terminating in the patient, then it follows that the agent must be, in a true sense, in the patient, either immediately or through a medium. Hence the axiom: Actio est in passo. It is evident that, with these two correlative predicaments and the consequent relation, we are describing finite efficient causality”(C. HART, op. cit., pp. 231-232).

[167] ARISTOTLE, Physics, IV, 11, 220a 25. Explaining the parts of this definition of time, Bittle writes: “It is the ‘number’ of movement, because we measure time by numbering the parts of the movement. These parts are not actual and separated, but potential, because the movement is continuous; consequently, the number of these parts is itself not actual, but potential. It is the number of ‘movement,’ insofar as this movement is successive and continuous in its passage from a starting point to a goal; time is found only in this kind of movement. It is the number of movement ‘according to before-and-after.’ This is obvious from the fact that the movement, which we call ‘time,’ is gradual and successive and is realized bit by bit, so that the parts of the movement follow each other in a steady flow; in other words, these parts stand to each in the relation of ‘before’ and ‘after.’ That is why St. Augustine says: ‘If nothing went by, there would be no future time: the present, however, if it always remained present, would not be time, but eternity’(ST. AUGUSTINE, Confessions, XI, 14)”(C. BITTLE, op. cit., p. 208).

[169]Exposition of Descartes’ Theory: Leibniz idealizes temporal relations while still professing belief in the reality of their terms. Descartes is even more of an idealist. He suppresses also that objective aspect of time, and reduces time to a ‘simple mode of thought.’ ‘Duration,’ according to him, ‘is identical with the substantial existence of things, it expresses the manner in which we represent a being maintaining its existence’(DESCARTES, Principles of Philosophy, I, 55). Time, he continues, which we distinguish from duration, is a mode of thought. As a matter of fact we predicate the same duration of movement as we do of immobile objects. Take two bodies engaged in different movements which traverse space during one hour. We regard the duration of such movements as being equal, even though their quantity be unequal. What then is time? In measuring the duration of earthly objects we compare it with the duration of the apparent movement of the planets. Time, therefore, is an extrinsic measure, a mode of evaluation which adds nothing to the reality of beings and modifies this reality in no manner whatsoever. In other words, it is a mode of thought (Cf. DESCARTES, op. cit., I, 57). 

     General Criticism of Descartes’ Theory: In constructing his system of philosophy Descartes has voided the laws of logic. After identifying duration and the substantial existence of beings – a fundamental principle in the Thomistic theory, it was quite logical to conclude that, since permanent duration is identical with substantial existence, changing duration or time must be concreted in successive existences, i.e., continuous movements. Reasoning of this sort has led to the scholastic theory of time.

     “But the opinions of the French philosopher on the reality of accidents led him to idealism. In Cartesian metaphysics accidents have no individual reality or existence; the distinction between accidents and substance is purely in the ideal order. Therefore, substantial existences, the only kind of existences, are permanent and endowed with absolutely indivisible duration, and the concept of a continuous succession is a fiction of the intellect, a mode of thought, having no real connection with contingent beings.

     “The Cartesian definition clearly savors of idealism. If, as Descartes says, temporal duration is the measure of contingent existences gauged by the movement of the planets, time is absolutely extrinsic to these existences and reducible to a simple mode of representation. But Descartes’ purely subjective conclusion is not the only alternative. For although the measurement used by ordinary men and scientists does not correspond adequately to the reality measured, i.e., to the continuous movements, each movement constitutes a real succession displaying all the characteristics of real time. The fact that we constantly must have recourse to this common standard of measurement, and that its use to gauge successions of different intrinsic values necessarily involves imperfections, does not warrant us in denying the existence of the real times characteristic of every movement which the scholastics call intrinsic times. Extrinsic time, therefore, does not preclude the idea of intrinsic and real time. Descartes believes in the existence of only the first of these two; his complete rejection of the second forces him into idealism”(D. NYS, Cosmology, vol. 2, Bruce, Milwaukee, 1942, pp. 333-334).  

[170] General Criticism of the Kantian Subjectivist Position on Time: “According to Immanuel Kant, the a priori form of time leaves its impress directly only on the subjective acts of sensitive life. Indirectly it affects also the objects of these acts, inasmuch as they are represented in internal actions. Matters cannot be otherwise if all data relating to time are derived from the same source, the a priori form of time.

     “Now what does experience say about this fundamental principle of the Kantian theory? Many times we exhaust the apparent reality of the objects surrounding us only by means of several sensitive representations. In order to take a pastoral scene in completely, we must regard each and every one of its constituent parts: the trees, the bushes, the flowers, the mountains, the brooks, and the animals. So that while the scene, despite the multiplicity and the complexity of its parts, appears to be one permanent and coexistent whole, the sensations which render us aware of it, succeed one another, or at least become more confused and more vague in proportion as they come closer to being coexistent. Permanence and coexistence, mobility and succession are the antithetical characteristics which differentiate the object of our sensitive representations.

     “How explain this radical difference? If the a priori form of time or the intuition of our inner sense affects directly only the acts of internal sensibility, and if it influences the objects represented only through the intermediary of these acts, both the subjective representations and the objects of these representations must be subject to the same temporal relations. It is inconceivable, therefore, that the ones be successive, and the others simultaneous or coexistent. In other words, the perception of any form of simultaneity by means of successive and continuous representations cannot be effected in the Kantian hypothesis. Moreover, the fact that the same external objects appear coexistent in time, and successive at another is incompatible with this a priori form which is unique and always the same. On the other hand, the fact is easily explained when we argue that the difference in our subjective impressions has its true source in the different states of external objects. This is an additional proof of the empirical origin of the concept of time (D. NYS, op. cit., pp. 329-331).    

[171] “‘Time’ is not a real being which exists in nature independent of the mind. Time, as we conceive it, extends without limit in the past and in the future. Since God is eternal, no limit can be assigned in the past or in the future in which God could not create bodies. Bodies, however, exist ‘in time.’ Hence, if time is a real entity, it must possess a positive eternity. Now, if time is without limit in the past and future, i.e., eternal, it must consist of an infinite number of present moments, because it consists of a series of successive present moments which flow continuously from the future through the present moment into the past. But an infinite number is impossible. Therefore ‘time,’ as a real being, is impossible.

     “Again, if time were a real being, it would be an entity existing in itself and for itself; in other words, it would be a substance and, since it is not spiritual, a material substance. Now, a material substance is a body. Time, however, is conceived as being in a continuous process of movement and change; hence, it would be a continuously moving and changing body. But moving and changing bodies are acknowledged by everybody to be ‘in time.’ Hence, ‘time,’ since it is a moving and changing body which exists ‘in time,’ demands another absolute time in which to exist as ‘in time.’ This second absolute time, for the same reason, demands a third absolute time; and this process must be repeated through an infinite regress. That, however, again necessitates an infinite number, which is a contradiction in terms. ‘Time,’ therefore, cannot be a real being… It is a philosophic error to consider ‘time,’ as we conceive it, to be a real being existing as such”(C. BITTLE, op. cit., pp. 199-200). 

[172]Individual time is manifold; general time is one and uniform. By individual (particular, intrinsic) time we understand the succession inherent in any concrete movement taken by itself. This time is independent of any comparison with a standard unit of time such as a minute, an hour, a day, a year. If no creature existed but a single body, and if this body underwent a successive change, time would be there in this movement, although in this case no measurement of it could be made by comparison with other movements. And the same applies to any movement of any being in the world: it has its own individual (particular, intrinsic) time by the mere fact that it is a continous movement, irrespective of the existence or movements of other beings.

     “By general (common, extrinsic) time we mean the successive movement of one thing taken as a standard according to which we measure the individual (particular, intrinsic) time of another thing. This standard of measurement is a matter of selection on our part. Such a standard must, of course, be one and uniform in character and not subject to appreciable variations; otherwise it would defeat its purpose. With us, this standard of measurement is the rotation of the earth on its axis once a ‘day’ and around the sun once in a ‘year.’ This is a natural division of general time, while the division of the year into twelve months, of the day into 24 hours, and of the hour into 60 minutes, is arbitrary. Since the rotation of the earth on its axis and in its orbit around the sun is practically always the same, general time is uniform. The individual time inherent in a being is the reason why it can be measured and also the reason why it can be used as a standard to measure other individual times”(C. BITTLE, op. cit., pp. 207-208).

[189] H. J. KOREN, op. cit., pp. 116-117. Kreyche explains the difference between a logical distinction (including the virtual distinction) and a real distinction (major and minor) and shows that act and potency are really distinct by a minor real distinction between metaphysical, not physical, principles of being: “In general, there are two types of distinction – logical and real. Formally considered, a logical distinction is a lack of identity, not in the order of things, but in the order of our concepts of things. Thus, if we conceive one and the same thing from two different points of view (for example, six and a half dozen eggs), the distinction in question is not a real, but a logical one. (Some logical distinctions are purely logical, as is the example given in the text; others are said to be virtual. A virtual distinction is a logical one that has some basis in the thing itself). By contrast, a real distinction is one that exists in the order of things themselves – that is, independently of our knowledge of them. Thus the distinction, let us say, between two parakeets exists apart from any consideration of the mind.

     “The example of the parakeets is an illustration of a real distinction between one thing and another. This type of distinction is known in philosophy as a ‘major’ real distinction, and the nature of such a distinction is obvious. Less obvious, however, is the distinction that exists, not between two things, but between two or more parts of a single thing, called a ‘minor’ real distinction. We may exemplify this latter  by the difference that exists between an arm and a leg. Though really distinct, an arm and a leg are not, properly speaking, ‘things.’ Yet they are distinct, really distinct, because an arm is not a leg, nor is a leg an arm. The example in question is a minor real distinction between physical parts. Most important of all for our own purposes is the distinction that exists, not between physical parts, but between metaphysical principles of being. This too is a minor real distinction, and it is the distinction that exists between potency and act.

     “From what we have just said it should be evident that potency and act are not merely distinct in our thinking about them – that is, not distinct by a type of logical distinction. They are really distinct in things themselves by a minor real distinction. It should hardly be necessarty at this point to ‘prove’ that potency and act are distinct, meaning really distinct. This is an immediate deduction from the nature of potency and act: in the measure in which it is in act it is perfect. To deny that potency and act are really distinct is to admit in effect that something could be perfect and imperfect from one and the same point of view, and this a plain contradiction.

     “Finally, it must be noted that any attempt to discount the real distinction between potency and act would render impossible any genuine solution to the very problems that give rise to this distinction. Thus, if potency and act are not really distinct, then the problem of change or becoming becomes insoluble. Further, if potency and act are not really distinct, there is no genuine solution to the problem of limitation. In conclusion, if these principles are in any sense real, it must be allowed that they are really distinct”(R. J. KREYCHE, op. cit., pp. 100-103).

[219] T. ALVIRA, L. CLAVELL, T. MELENDO, op. cit., p. 91. Owens writes: “The essence can exist in reality and in the human intellect. In reality it exists in individuals, as humanity exists in millions of men. The same essence, humanity, is found separately in every one of these many individuals. It is common to them all. The same essence, moreover, can exist in your intellect or in the intellect of anyone else who thinks of it. In this cognitional existence it is no longer individual but specific. It is the universal species ‘man,’ or human nature in its universality. As a universal, it represents all individual men in the one concept. It has a unity of its own as universal, just as in any particular man it has a unity that is individual”(J. OWENS, op. cit., p. 133).

[220] De Ente et Essentia, chapter 1.

[221]Physical essence is an essence as it exists concretely in nature, independent of the mind’s thinking. Such an essence is taken objectively, and thereby we mean the sum of those fundamental elements which, in the natural order of the world, constitute the object’s innermost being, no matter how our mind may conceive them in its thoughts. Man, for instance, consists of two essential principles in his physical nature, namely, body and soul. The same is true of animals and plants; they, too, consist of a body and a life giving principle. These various classes of living beings are composed of the same chemical materials (matter) as the determinable element of their physical being; that plants and brutes and men differ so greatly among themselves is due to their determining life principle (form, soul) which uses this common material according to the needs of its specific nature. These elements or principles constitute the essence of a thing in the concrete physical order, irrespective of any mind that may contemplate them, and hence such an essence is called a ‘physical’ essence.

     “If such a physical essence is simple, i.e., constituted by a single substantial principle, and not by two or more substantial part-principles, it is a simple physical essence. God’s essence and that of pure spirits are one in nature and not compounded by two or more substantial parts. But if this essence is composite, i.e., if it consists of two or more substantial part-principles (like body and soul), which together constitute one complete nature, it is a composite physical essence (C. BITTLE, op. cit., pp. 118-119).”

[222]Metaphysical essence is the sum of the various grades of being which constitute a thing in the abstract concepts of the mind. Here we do not consider an object as it exists concretely in the physical world, but according to the manner in which it is conceived by the mind. An example will clarify this. In the physical order of existence, man is a compound of body and soul; notwithstanding this composition, he is a single being or essence. When the mind conceives man as a corporeal, living, sentient, rational substance,’ the mind is fully aware of the fact that he does not consist of one physical part which is his ‘substance,’ and of a second physical part which is his ‘body,’ and of a third physical part which is his ‘vegetant life,’ and of a fourth physical part which is his ‘sentiency,’ and of a fifth and final physical part which is his ‘rationality.’ Man is a substance, and this substance is at one and the same time corporeal and living and sentient and rational – one reality expressed in five objectively different concepts, like a set of photographs taken of the same person from five different angles. The five concepts, taken alone by themselves, give but a partial and inadequate idea of the one essence; taken together, however, they supplement each other and give a correct and complete idea of man’s essence. The mind must represent the one reality by means of five objectively different concepts, because it is incapable of expressing it in a single all-comprehensive concept.

     “Such parts of an essence which are the ‘grades of being’ of one concrete nature (in reality identical and inseparable in thought) are called metaphysical parts; and the essence which is conceived by the mind as consisting of such metaphysical grades of being is called the metaphysical essence of the thing. Needless to say, it is possible to express a number of such metaphysical grades of being by means of a single term. A corporeal substance is termed a ‘body’; a living corporeal substance is termed a ‘plant.’ A sentient, living, corporeal is termed an ‘animal.’ A rational, sentient, living corporeal substance is termed a ‘man’; and a man is often termed a ‘rational animal.’ A glance shows us that this latter mode of expression is the definition of man according to his proximate genus and specific difference. Whichever way we express the essence of a thing, whether by an enumeration of the single grades of being or by a definition according to the proximate genus and specific difference, in either case we express the metaphysical essence of that thing”(C. BITTLE, op. cit., pp. 119-120).”

[236] De Torre writes: “‘To exist’ is not quite the same as ‘to be.’ It comes from the Latin existere, which literally means to ‘stand out’ From there comes existentia in Latin, and ‘existence’ in English, and it means the fact of being, not the act of being. ‘Fact’ comes from the Latin factum, which means ‘made’ or finished. Existence signifies the fact of being; when something is already there, has come to the act of being, then it exists, it ‘stands out of,’ it is no longer a possibility (in German, while ‘being’ is Sein, existence is Dasein or being-there).

     “There is a great tendency in modern philosophy to equate existence with being. But ‘being’ refers to the act or actuality of being. The fact that all the things we see have acts of being which are limited by their essences indicates that their being is caused or received. Therefore, someone has made them come to be (though not necessarily in time). And this one cannot have come to be, and so it is pure act of being without any essence that will limit it, or, in other words, with an essence which is precisely to be. What is the essence of God? To be, which is not the essence of anything else. Nothing else is by essence, only God.

     “That is why being is not identical with existence. Existence is the fact of being, ‘fact’ meaning ‘what is made.’ In other words, while esse is a metaphysical principle, ‘to exist’ is the result of having esse. One is the principle, and the other is the result. Esse is a principle, because nothing can be without the act of being. Existere or to exist is the result of having esse”(J. DE TORRE, op. cit., pp. 76-77).

[243] Alvira, Clavell and Melendo note that, “according to some authors, the real distinction between the act of being and essence was made even before St. Thomas Aquinas. Its origin could be traced back to Aristotle who said in that famous passage of the Posterior Analytics (II, 7, 92b ff.) with regard to man, that the τò δὲ̀  τί (essence) is not the εі̃ναι (act of being). Some authors have considered this distinction to be merely a distinction of reason, not a real one. But Aristotle further explained that ‘the act of being of a thing is not its own essence, for the act of being does not belong to any genus.’ Despite this contribution, however, one does not find in his works a complete development of this doctrine”(T. ALVIRA, L. CLAVELL, T. MELENDO, op. cit., pp. 109-110).

[252] Suarez and the Suarezian school “hold for a mental distinction between essence and existence. For it is by existence that a thing becomes real from a state of possibility. All its reality is due to its existence. There is no distinct reality such as essence. Essence cannot be without  existence.

     “The Thomist concedes that essence cannot be isolated from esse as if essence could really be apart from esse as oxygen can be physically separated from hydrogen as components of water. The difficulty is in understanding the meaning of a real distinction which cannot be locally distinct.

     “Essence and esse are not parts of a being in the same way as integral parts that can be locally separated. They are entitative components of the finite. The reality which esse confers on essence is to make an essence really existing. But it does not follow from this that all the reality in the finite being is esse. There must be a real subject of which esse is the act. This real subject is a real potency that receives esse. Reality is not purely the actual in finite being. There is also the reality of potency. So too matter is a real potency distinct in a thing from the substantial act, the form. Essence is not real in the existential order without the act of being and yet it is not identical with the act of being. Essence and act of being are coprinciples of the being of finite things. Finite reality is not purely esse but a compound of potency and act, an imperfect mode of existence.

     “What results from the union of essence and esse is the existent, the individual existing thing, the supposit. Essence and esse complement one another as potency and act, as what is existing and the act of being in the constitution of finite being ultimately outside its causes. Esse is not related to essence as another substance nor as an accident but rather as the ultimate actuality of the essence.

     “The doctrine of the real distinction between essence and act of being is a basically integral part of the Thomistic synthesis. It is not a more or less accidental corollary attached to the metaphysics of St. Thomas. It is a fundamental application of the doctrine of potency and act to the understanding of finite being. For essence stands to esse as potency to act. The real distinction between potency and act is resolved in the relation of the entitative parts of finite being. ‘It must be considered that as esse and what is differ in simple things according to intention so in composite things they differ really’(In Boethium de Hebdomadibus, lecture 2)”(K. DOUGHERTY, op. cit., pp. 131-132).

[254] The distinction between nature and suppositum is of paramount importance in theology. St. Thomas Aquinas made use of this doctrine to express with precision the mystery of the Incarnation: the human nature of Christ – despite its being singular and its full perfection as nature – cannot be a suppositum, for it does not include in itself the act of being.

[266] St. Thomas Aquinas always maintained this doctrine, as can be verified from his early writings as well as the later ones (cf. In III Sent., d. 6, q. 2, a. 2 ; Quodlibet, IX, a. 3, and Summa Theologiae, III, q. 17, a. 3, c.). This was explicitly defended by Capreolus, one of the commentators of the Angelic Doctor (cf. Defensiones Theologicae divi Thomae Aquinitatis, T. Pégues Ed., V, Tours, 1907, pp. 105-107). Later on, Suarez and Cajetan regarded the essence (and not esse) as the ontological basis of the subsisting subject.

[270] “In the order of activity this self-sufficient being is also the ultimate principle which acts, and to which all actions are ultimately attributed. The nature is the ultimate principle through which or by which activity is exercised, but the supposit is the ultimate principle which exercises the activity. For instance, this person, Peter, is the ultimate principle which exercises through his rational nature the act of thinking; this supposit, Fido, is the ultimate principle which performs through its canine nature the act of barking. Hence the axiom: ‘Actions belong to the supposits.’

     “Subsistence adds to individuality autonomy of independence. This autonomy of independence is an analogous concept and increases the higher we climb on the scale of beings. While on the lowest grade of being hardly any difference between the individual and the supposit is discernible, precisely because there is very little independence, this independence becomes more and more striking as we climb highwer on the scale of beings. Minerals, for example, can merely exist in themselves and act upon others in virtue of inherent powers; plants, in addition, have an intrinsic principle of growth and reproduction; to whatever self-sufficiency a plant has animals add the power of guiding themselves by means of sensation in their activity; man surpasses animals in autonomy because he has also the power to determine for himself for which purpose he is going to act. Thus subsistence adds to individuality an increasing degree of self-sufficiency”(H. J. KOREN, op. cit., pp. 201-202).
