PHYSICAL BEING IS THAT WHICH IS NOT IN A SUBJECT.
Not to be in a subject is then the common characteristic of all "being," if, by "not being in a subject," we mean "not to form part of any subject," and "not to contribute to the formation of a unity therewith." Indeed, that which contributes to the formation of a composite being, with something else, could not be in that thing as in a subject; form therefore is not in matter as in a subject, and neither is "man" in Socrates as in a subject, because "man" forms part of Socrates.[363] Thus, "being" is that which is not in a subject. If we add that "being" is not predicated of any subject, we must also add, "insofar as this subject is something different from itself;" otherwise "man," predicated of some one man, would not be comprised within the definition of "being," if (in asserting that "being" is not predicated of any subject), we did not add, "so far as this subject is something different from itself." When I say, "Socrates is a man," I am practically saying, "White is white," and not, "wood is white." While actually asserting that "Socrates is a man," I am asserting that a particular man is a man, and to say "The man who is in Socrates is a man," amounts to saying "Socrates is Socrates," or, "that particular reasonable living organism is a living organism."
ALL THE OTHER PHYSICAL CATEGORIES REFER TO MATTER, FORM OR COMBINATION.
It might however be objected that the property of "being" does not consist in being a subject; for the difference (as, for instance, a biped), is also one of those things which are not in a subject.[363] If "biped" be considered as a part of being, we are compelled to recognize that "biped" is not in a subject; but if by "biped" we do not mean some particular "being" but the property of being a biped, then we are no longer speaking of a being, but of a quality, and "biped" will be in a subject.
But time and place do not seem to be in a subject! If we define time as "the measure of movement,"[364] (there are two possibilities). First, time might be measured movement; and then it will be in movement as in a subject, while movement itself will be in the moved thing. Or, time will be what measures (the soul, or the present moment), and then it will be in what measures as in a subject. As to space, as it is the limit of what contains, it will also reside in what contains.[365] It is otherwise with the "being" that we are here considering. "Being," then, will have to be considered as consisting in either one, or in several, or in all the properties of which we are speaking; because these properties simultaneously suit matter, form, and the combination.
BEING DRAWS ITS EXISTENCE FROM THE INTELLIGIBLE.
6. It may perhaps be objected that we have here indicated the properties of "being," but we have not described its nature. Such a request amounts to asking to see what sense-being is; now sense-being is, and "being" is not something which can be seen.
What then? Are fire and water not beings? Doubtless, they are. But are they beings merely because they are visible? No. Is it because they contain matter? No. Is it because they have a form? No. Is it because they are combinations? No. They are "beings," because they "are."
But one can also say that quantity, as well as that quality "is!" Yes, doubtless, but if we speak thus about quantity and quality, it is only by a figure of speech.[343],[361], [366]
Then, in what consists the being of earth, fire, and other similar things? What is the difference between the being of these things and of others? The essence of the earth, of the fire, and so forth, exists in an absolute manner, while the essence of other things (is relative) and for instance, means merely being white. "Is" added to white is not the same thing as "essence" taken absolutely; is it? Certainly not. Essence taken absolutely is essence in the first degree; "to be" added to white, is essence by participation, essence in the second degree; for "to be," added to white, makes white an essence; and white added to essence makes the being white; that is why white is an accident for essence, and "to be" an accident to white. It is not the same thing as if we said, Socrates is white, and, the White is Socrates; for in both cases Socrates is the same being; but it is not thus with whiteness; for, in the second case, Socrates is contained in the white, and in the first case, white is a pure accident. When we say, the being is white, the white is an accident of being; but when we say, the White is essence, the white contains essence. In short, white possesses existence only because it refers to "being," and is in "being." It is therefore from "being" that it receives its existence. On the contrary, essence draws its existence from itself; and from white it receives whiteness, not because it is in the white, but because the white is within it.[366] As the essence which is in the sense-world is not Essence by itself, we must say that it draws its existence from the veritable Essence, in itself; and, finally, the White in itself possesses essence because it participates in the intelligible Essence.
