Ontology, or the Theory of Being

by P. Coffey

Whence does the human mind derive these ideal types, these concepts or definitions of the nature of things? It derives them from actually experienced reality by abstraction, comparison, generalization, and reflection on the data of its experience.[163] Hence it follows that the ontological truth of things is not known by the mind antecedently to the formation of the mental type. It is, of course, in the things antecedently to any judgment we form about the things; and the logical truth of our judgments is dependent on it, for logical truth is the conformity of our judgments with the real nature of things. But antecedently to all exercise of human thought, antecedently to our conception of the nature of a thing, the thing has not for us formal or actual ontological truth: it has only fundamental or potential ontological truth. If in this condition reality had actual ontological truth for us, there would be no ground for our distinguishing mentally between the reality and the truth of things; whereas the existence of this mental or logical distinction is undeniable. The concept of reality is the concept of something absolute; the concept of ontological truth is the concept of something relative, not of an absolute but of a relative property of being.

But if for the human mind the ontological truth of things is—at least proximately, immediately, and in the first place—their conformity with the abstract concepts of essences or natures, concepts derived by the mind from an analysis of its experience, how can this ontological truth be one for all men, or immutable and necessary? For, since men form different and divergent and conflicting conceptions as to the natures of things, and so have different views and standards of truth for things, ontological truth would seem, according to the exposition just outlined, to be not one but manifold, not immutable but variable: consequences which surely cannot be admitted? The answer to this difficulty will lead us to a deeper and more fundamental conception of what ontological truth really is.

First, then, we must consider that all men are endowed with the same sort of intellect, an intellect capable of some insight at least into the nature of things; that therefore they abstract the same transcendental notions and the same widest concepts from their experience: transcendental concepts of being, unity, truth, goodness; generic concepts of substance, matter, spirit, cause, of accident, quantity, multitude, number, identity, similarity, distinction, diversity, etc. They also form the same specific concepts of possible essences. Although, therefore, they may disagree and err in regard to the application of those concepts, especially of the lower, richer and more complex specific concepts, to the actual data of their experience, they agree in the fact that they have those common concepts or idea-types of reality; also in the fact that when they apply those concepts rightly (i.e. by logically true judgments) to the things that make up their experience, they have so far grasped the real natures of these things; and finally in recognizing that the ontological truth of these things lies in the conformity of the latter with their true and proper mental types or essences. And just as each of these latter is one, indivisible, immutable, necessary and eternal ([14], [15]), so is the ontological truth of things, whether possible or actual, one, indivisible, immutable, necessary and eternal. Of course, just as the human mind does not constitute but only apprehends reality, so the human mind does not constitute the ontological truth of reality, but only apprehends it. Every reality is capable of producing in the human mind a more or less adequate mental representation of itself: in this lies what we may call the potential or fundamental ontological truth of reality. When it does produce such a mental concept of itself its relation of conformity to this concept is its formal ontological truth. Of course the human mind may err in applying to any reality a wrong concept; when it does it has so far failed to grasp the real nature of the thing and therefore the ontological truth which is really identical with this nature. But the thing still has its ontological truth, independently of the erring mind; not only fundamental truth, but also possibly formal truth in so far as it may be rightly apprehended, and thus related to its proper mental type, by other human minds. Reality itself, therefore, is not and cannot be false, as we shall see more fully later; error or falsity is an accident only of the mind interpreting reality.

41. Ontological Truth Considered Synthetically, from the Standpoint of its Ultimate Real Basis.—So far we have explained ontological truth as a relation of reality to the [pg 161] human intelligence; but this relation is not one of dependence. The objective term of the relation, the reality itself, is anterior to the human mind, it is not constituted by the latter. The subjective term, the abstract concept, is indeed as a vital product dependent on the mind, but as representative of reality it is determined only by the latter. Is there, however, an Intelligence to which reality is essentially conformed, other than the human intelligence? Granted the actual existence of contingent realities, and granted that the human mind can derive from these realities rational principles which it sees to be necessarily and universally applicable to all the data of experience, we can demonstrate the existence of a Necessary Being, a First and Self-Existent Intelligence. Realizing, then, that God has created all things according to Infinite Wisdom, we can see that the essences of things are imitations of exemplar ideas in the Divine Mind ([20]). On the Divine Mind they depend essentially for their reality and intelligibility. It is because all created realities, including the human mind itself, are adumbrations of the Divine Essence, that they are intelligible to the human mind. Thus we see that in the ontological order, in the order of real gradation and dependence among things, as distinct from the order of human experience,[164] the reason why reality has ontological truth for the human mind is because it is antecedently and essentially in accord with the Divine Mind from which it derives its intelligibility. Although, therefore, ontological truth is for us proximately and immediately the conformity of reality with our own conceptions, it is primarily and fundamentally the essential conformity of all reality with the Divine Mind. All reality, actual and possible, including the Divine Essence itself, is actually comprehended by the Divine Mind, is actually in conformity with the exemplar ideas in the Divine Mind, and has therefore ontological truth even independently of its relation to created minds; but “in the (impossible) hypothesis of the absence of all intellect, such a thing as truth would be inconceivable”.[165]

The reason, therefore, why things are ontologically true for our minds, why our minds can apprehend their essences, why we can have any true knowledge about them, is in fact because both our minds and all things else, being expressions of the Divine [pg 162] Essence, are in essential conformity with the Divine Intellect. Not that we must know all this in order to have any logical truth, any true knowledge, about things; or in order to ascribe to things the ontological truth which consists in their conformity with our conception of their nature. The atheist can have a true knowledge of things and can recognize in them their conformity with his mental conception of their nature; only he is unaware of the real and fundamental reason why he can do so. Nor can he, of course, while denying the existence of God, rise to the fuller conception of ontological truth which consists in the essential conformity of all reality with the Divine Intellect, and its essential dependence on the latter for its intelligibility to the human intellect.

Naturally, it is this latter and fuller conception of ontological truth that has been at all times expounded by scholastic philosophers.[166] We may therefore, define ontological truth as the essential conformity of reality, as an object of thought, with intellect, and primarily and especially with the Divine Intellect.

The conformity of reality with the Divine Intellect is described as essential to reality, in the sense that the reality is dependent on the Divine Intellect for its intelligibility; it derives its intelligibility from the latter. The conformity of reality with the human intellect is also essential in the sense that potential conformity with the latter is inseparable from reality; it is an aspect really identical with, and only logically distinct from, the latter. But inasmuch as the actual conformity of reality with our human conception of it is contingent on the existence of human intelligences, and is not ultimately dependent on the latter, inasmuch as reality does not derive its intelligibility ultimately from this conception—seeing that rather this conception is derived from the reality and is ultimately dependent on the Divine Exemplar,—this conformity of reality with the human mind is sometimes spoken of as accidental to reality in contrast with the relation of dependence which exists between reality and the Divine Mind.

Bearing in mind that reality derives its intelligibility from its essential conformity with the Divine Mind, and that the human mind derives its truth from the reality, we can understand how it has been said of truth in general that it is first in the Uncreated Intellect, then in things, then in created intellects; that the primary source and measure of all truth is the Divine Intellect Itself Unmeasured, “mensurans, non mensuratus”; that created reality is measured by, or conformed with, the Divine Intellect, and is in turn the measure of the human intellect, conforming the latter with itself, “mensurans et mensurata”; and that, finally, the human intellect, measured by created reality and the Divine Mind, is itself the measure of no natural things but only of the products of human art, “intellectus noster ... non mensurans quidem res naturales, sed artificiales tantum”.[167]

Is truth one, then, or is it manifold? Logical truth is manifold—multiplied by the number of created intelligences, and by the number of distinct cognitions in each. The primary ontological truth which consists in the conformity of all reality with the Divine Intellect is one: there is no real plurality of archetype ideas in the Divine Mind; they are manifold only to our imperfect human mode of thinking. The secondary ontological truth which consists in the conformity of things with the abstract concepts of created intelligences is conditioned by, and multiplied with, the manifoldness of the latter.[168]

Again to the question: Is truth eternal or temporal?—we reply in a similar way that the truth of the Divine comprehension of reality, actual and possible, is eternal, but that no other truth is eternal. There is no eternal truth outside of God. Created things are not eternal; and truth is consecutive on reality: where there is no reality there is no ontological truth: the conformity of things with human conceptions and the logical truth of the latter are both alike temporal.[169]
