But prior (ontologically) to this mental existence, and as partial cause of the latter, there is the real existence or being, which reality has independently of its being known by any individual human mind. Real being, then, as distinguished here from ideal being, is that which exists or can exist extramentally, whether it is known by the human mind or not, i.e. whether it exists also mentally or not.
That there is such real being, apart from the “thought”-being whereby the mind is constituted formally knowing, is proved elsewhere; as also that this esse intentionale has modes which cannot be attributed to the esse reale. We merely note these points here in order to indicate the errors involved in the opposite contentions. Our concepts are characterized by abstractness, by a consequent static immutability, by a plurality often resulting from purely mental distinctions, by a universality which transcends those distinctions and unifies the variety of all subordinate concepts in the widest concept of being. Now if, for example, we attribute the unifying mental mode of universality to real being, we must draw the pantheistic conclusion that all real being is one: the logical outcome of extreme realism. If, again, we transfer purely mental distinctions to the unity of the Absolute or Supreme Being, thus making them real, we thereby deny infinite perfection to the most perfect being conceivable: an error of which some catholic philosophers of the later middle ages have been accused with some foundation. If, finally, we identify the esse reale with the esse intentionale, and this with the thought-process itself, we find ourselves at the starting-point of Hegelian monism.[68]
5. Fundamental Distinctions in Real Being.—Leaving logical and ideal being aside, and fixing our attention exclusively on real being, we may indicate here a few of the most fundamental distinctions which experience enables us to recognize in our study of the universal order of things.
(a) Possible or Potential Being and Actual Being.—The first of these distinctions is that between possibility and actuality, between [pg 047] that which can be and that which actually is. For a proper understanding of this distinction, which will be dealt with presently, it is necessary to note here the following divisions of actual being, which will be studied in detail later on.
(b) Infinite Being and Finite Beings.—All people have a sufficiently clear notion of Infinite Being, or Infinitely Perfect Being: though not all philosophers are agreed as to how precisely we get this notion, or whether there actually exists such a being, or whether if such being does exist we can attain to a certain knowledge of such existence. By infinite being we mean a being possessing all conceivable perfections in the most perfect conceivable manner; and by finite beings all such beings as have actually any conceivable limitation to their perfection. About these nominal definitions there is no dispute; and scholasticism identifies their respective objects with God and creatures.
(c) Necessary Being and Contingent Beings.—Necessary being we conceive as that being which exists of necessity: being which if conceived at all cannot be conceived as non-existent: being in the very concept of which is essentially involved the concept of actual existence: so that the attempt to conceive such being as non-existent would be an attempt to conceive what would be self-contradictory. Contingent being, on the other hand, is being which is conceived not to exist of necessity: being which may be conceived as not actually existent: being in the concept of which is not involved the concept of actual existence. The same observations apply to this distinction as to the preceding one. It is obvious that any being which we regard as actual we must regard either as necessary or as contingent; and, secondly, that necessary being must be considered as absolutely independent, as having its actual existence from itself, by its own nature; while contingent being must be considered as dependent for its actual existence on some being other than itself. Hence necessary being is termed Ens a se, contingent being Ens ab alio.
(d) Absolute Being and Relative Beings.—In modern philosophy the terms “absolute” and “relative,” as applied to being, correspond roughly with the terms “God” and “creatures” in the usage of theistic philosophers. But the former pair of terms is really of wider application than the latter. The term absolute means, etymologically, that which is loosed, unfettered, disengaged or free from bonds (absolutum, ab-solvere, solvo = se-luo, from λύω): that, therefore, which is not bound up with anything else, [pg 048] which is in some sense self-sufficing, independent; while the relative is that which is in some way bound up with something else, and which is so far not self-sufficing or independent. That, therefore, is ontologically absolute which is in some sense self-sufficing, independent of other things, in its existence; while the ontologically relative is that which depends in some real way for its existence on something else. Again, that is logically absolute which can be conceived and known by us without reference to anything else; while the logically relative is that which we can conceive and know only through our knowledge of something else. And since we usually name things according to the way in which we conceive them, we regard as absolute any being which is by itself and of itself that which we conceive it to be, or that which its name implies; and as relative any being which is what its name implies only in virtue of some relation to something else.[69] Thus, a man is a man absolutely, while he is a friend only relatively to others.
It is obvious that the primary and general meaning of the terms “absolute” and “relative” can be applied and extended in a variety of ways. For instance, all being may be said to be “relative” to the knowing mind, in the sense that all knowledge involves a transcendental relation of the known object to the knowing subject. In this widest and most improper sense even God Himself is relative, not however as being, but as known. Again, when we apply the same attribute to a variety of things we may see that it is found in one of them in the most perfect manner conceivable, or at least in a fuller and higher degree than it is found in the others; and that it is found in these others only with some sort of subordination to, and dependence on, the former: we then say that it belongs to this primarily or absolutely, and to the others only secondarily or relatively. This is a less improper application of the terms than in the preceding case. What we have especially to remember here is that there are many different kinds of dependence or subordination, all alike giving rise to the same usage.
Hence, applying the terms absolute and relative to the predicate “being” or “real” or “reality,” it is obvious in the first place that the potential as such can be called “being,” or “reality” only in relation to the actual. It is the actual that is being simpliciter, par excellence; the potential is so only in [pg 049] relation to this.[70] Again, substances may be termed beings absolutely, while accidents are beings only relatively, because of their dependence on substances; though this relation is quite different from the relation of potential to actual being. Finally all finite, contingent realities, actual and possible, are what they are only because of their dependence on the Infinite and Necessary Being: and hence the former are relative and the latter absolute; though here again the relation is different from that of accident to substance, or of potential to actual.
Since the order of being includes all orders, and since a being is absolutely such-or-such in any order only when that being realizes in all its fulness and purity such-or-such reality, it follows that the being which realizes in all its fulness the reality of being is the Absolute Being in the highest possible sense of this term. This concept of Absolute Being is the richest and most comprehensive of all possible concepts: it is the very antithesis of that other concept of “being in general” which is common to everything and distinguished only from nothingness. It includes in itself all actual and possible modes and grades and perfections of finite things, apart from their limitations, embodying all of them in the one highest and richest concept of that which makes all of them real and actual, viz. the concept of Actuality or Actual Reality itself.
