(g) The notion of being is so universal that it transcends all actual and conceivable determinate modes of being: it embraces infinite being and all modes of finite being. In other words it is not itself a generic, but a transcendental notion. Wider than all, even the widest and highest genera, it is not itself a genus. A genus is determinable into its species by the addition of differences which lie outside the concept of the genus itself; being, [pg 036] as we have seen, is not in this way determinable into its modes.
2. In what Sense are all Things that Exist or can Exist said to be “Real” or to have “Being”?—A generic concept can be predicated univocally, i.e. in the same sense, of its subordinate species. These latter differ from one another by characteristics which lie outside the concept of the genus, while they all agree in realizing the generic concept itself: they do not of course realize it in the same way,[53] but as such it is really and truly in each of them and is predicated in the same sense of each. But the characteristics which differentiate all genera and species from one another, and from the common notion of being, in which they all agree, are likewise being. That in which they differ is being, as well as that in which they agree. Hence we do not predicate “being” univocally of its various modes. When we say of the various classes of things which make up our experience that they are “real” (or “realities,” or “beings”), we do not apply this predicate in altogether the same sense to the several classes; for as applied to each class it connotes the whole content of each, not merely the part in which this agrees with, but also the part in which it differs from, the others. Nor yet do we apply the concept of “being” in a totally different sense to each separate determinate mode of being. When we predicate “being” of its modes the predication is not merely equivocal. The concept expressed by the predicate-term “being” is not totally different as applied to each subject-mode; for in all cases alike it implies either actual existence or some relation thereto. It only remains, therefore, that we must regard the notion of being, when predicated of its several modes, as partly the same and partly different; and this is what we mean when we say that the concept of being is analogical, that being is predicated analogically of its various modes.
Analogical predication is of two kinds: a term or concept may be affirmed of a variety of subjects either by analogy of attribution or by analogy of proportion. We may, for instance, speak not only of a man as “healthy,” but also of his food, his countenance, [pg 037] his occupation, his companionship, etc., as “healthy”. Now health is found really only in the man, but it is attributed to the other things owing to some extrinsic but real connexion which they have with his health, whether as cause, or effect, or indication, of the latter. This is analogy of attribution; the subject of which the predicate is properly and primarily affirmed being known as the primary analogue or analogum princeps, those to which it is transferred being called the analogata. It underlies the figures of speech known as metynomy and synechdoche. Now on account of the various relations that exist between the different modes of being, relations of cause and effect, whole and part, means and end, ground and consequence, etc.—relations which constitute the orders of existing and possible things, the physical and the metaphysical orders—being is of course predicated of its modes by analogy of attribution; and in such predication infinite being is the primary analogue for finite beings, and the substance-mode of being for all accident-modes of being.
Inasmuch, however, as being is not merely attributed to these modes extrinsically, but belongs to all of them intrinsically, it is also predicated of them by analogy of proportion. This latter sort of analogy is based on similarity of relations. For example, the act of understanding bears a relation to the mind similar to that which the act of seeing bears to the eye, and hence we say of the mind that it “sees” things when it understands them. Or, again, we speak of a verdant valley in the sunshine as “smiling,” because its appearance bears a relation to the valley similar to that which a smile bears to the human countenance. Or again, we speak of the parched earth as “thirsting” for the rains, or of the devout soul as “thirsting” for God, because these relations are recognized as similar to that of a thirsty person towards the drink for which he thirsts. In all such cases the analogical concept implies not indeed the same attribute (differently realized) in all the analogues (as in univocal predication) but rather a similarity in the relation or proportion in which each analogue embodies or realizes some attribute or attributes peculiar to itself. Seeing is to the eye as understanding is to the mind; smiling is to the countenance as the pleasing appearance of its natural features is to the valley. Rain is to the parched earth, and God is to the devout soul, as drink is to the thirsty person. It will be noted that in all such cases the analogical concept is affirmed primarily and properly of some one thing (the analogum princeps), [pg 038] and of the other only secondarily, and relatively to the former.
Now, if we reflect on the manner in which being is affirmed of its various modes (e.g. of the infinite and the finite; or of substance and accident; or of spiritual and corporeal substances; or of quantities, or qualities, or causes, etc.) we can see firstly that although these differ from one another by all that each of them is, by the whole being of each, yet there is an all-pervading similarity between the relations which these modes bear each to its own existence. All have, or can have, actual existence: each according to the grade of perfection of its own reality. If we conceive infinite being as the cause of all finite beings, then the former exists in a manner appropriate to its all-perfect reality, and finite beings in a manner proportionate to their limited realities; and so of the various modes of finite being among themselves. Moreover, we can see secondly, as will be explained more fully below,[54] that being is affirmed of the finite by virtue of its dependence on the infinite, and of accident by virtue of its dependence on substance.[55] Being or reality is therefore predicated of its modes by analogy of proportion.[56]
Is a concept, when applied in this way, one, or is it really manifold? It is not simply one, for this would yield univocal predication; nor is it simply manifold, for this would give equivocal predication. Being, considered in its vague, imperfect, inadequate sense, as involving some common or similar proportion or relation to existence in all its analogues, is one; considered as representing clearly and adequately what is thus similarly related to each of the analogues, it is manifold.
Analogy of proportion is the basis of the figure of speech known as metaphor. It would be a mistake, however, to infer from this that what is thus analogically predicated of a number of things belongs intrinsically and properly only to one of them, being transferred by a mere extrinsic denomination to the others; and that therefore it does not express any genuine knowledge [pg 039] on our part about the nature of these other things. It does give us real knowledge about them. Metaphor is not equivocation; but perhaps more usually it is understood not to give us real knowledge because it is understood to be based on resemblances that are merely fanciful, not real. Still, no matter how slender and remote be the proportional resemblance on which the analogical use of language is based, in so far forth as it has such a real basis it gives us real insight into the nature of the analogues. And if we hesitate to describe such a use of language as “metaphorical,” this is only because “metaphor” perhaps too commonly connotes a certain transferred and improper extension of the meaning of terms, based upon a purely fanciful resemblance.
All our language is primarily and properly expressive of concepts derived from the sensible appearances of material realities. As applied to the suprasensible, intelligible aspects of these realities, such as substance and cause, or to spiritual realities, such as the human soul and God, it is analogical in another sense; not as opposed to univocal, but as opposed to proper. That is, it expresses concepts which are not formed directly from the presence of the things which they signify, but are gathered from other things to which the latter are necessarily related in a variety of ways.[57] Considering the origin of our knowledge, the material, the sensible, the phenomenal, comes first in order, and moulds our concepts and language primarily to its own proper representation and expression; while the spiritual, the intelligible, the substantial, comes later, and must make use of the concepts and language thus already moulded.
If we consider, however, not the order in which we get our knowledge, but the order of reality in the objects of our knowledge, being or reality is primarily and more properly predicated of the infinite than of the finite, of the Creator than of the creature, of the spiritual than of the material, of substances than of their accidents and sensible manifestations or phenomena. Yet we do not predicate being or reality of the finite, or of creatures, in a mere transferred, extrinsic, improper sense, as if these were mere manifestations of the infinite, or mere effects of the First Cause, to which alone reality would properly belong. For creatures, finite things, are in a true and proper sense also real.
Duns Scotus and those who think with him contend that the concept of being, derived as it is from our experience of finite being, if applied only [pg 040] analogically to infinite being would give us no genuine knowledge about the latter. They maintain that whenever a universal concept is applied to the objects in which it is realized intrinsically, it is affirmed of these objects univocally. The notion of being, in its most imperfect, inadequate, indeterminate sense, is, they say, one and the same in so far forth as it is applicable to the infinite and the finite, and to all the modes of the finite; and it is therefore predicated of all univocally.[58] But although they apply the concept of being univocally to the infinite and the finite, i.e. to God and creatures, they admit that the reality corresponding to this univocal concept is totally different in God and in creatures: that God differs by all that He is from creatures, and they by all that they are from Him. While, however, Scotists emphasize the formal oneness or identity of the indeterminate common concept, followers of St. Thomas emphasize the fact that the various modes of being differ totally, by all that each of them is, from one another; and, from this radical diversity in the modes of being, they infer that the common concept should not be regarded as simply the same, but only as proportionally the same, as expressive of a similar relation of each intrinsically different mode of reality to actual existence.
