FIVE PHYSICAL CATEGORIES.
We decide, therefore, that the three first things (matter, form, and their combination) contribute to the formation of a single genus, which, by a figure of speech, we call ("corporeal) Being," a genus which is common to them, and whose name applies to all three. Then come the other genera; such as relation, quantity and quality; the (relation of) being "contained in place," and "in time"; movement; and place and time. But as the category of "time" and "place" would render superfluous that of "being in place" and of "being in time,"[353] we should limit ourselves to the recognition of five genera, of which the first ("being") comprises matter, form and the combination.[354] If, however, we should not count matter, form and combination as a single genus, our analysis will assume the following shape: matter, form, combination, relation, quantity, quality, and movement. Otherwise, the latter three might be subsumed under relation, which possesses more extension than they.
SENSE-BEING.
4. What is the common element in these three things (matter, form and their combination)? What constitutes their (sublunary, mundane or) earthly "being"? Is it because matter, form and their combination form a foundation for other things? In that case, as matter is the foundation, or seat of form, then form will not be in the genus of "being." But, as the combination also forms foundation for other things, then form united to matter will be the subject of the combinations, or rather, of all the things which are posterior to the combination, as quantity, quality, and movement.
BEING IS THAT WHICH IS PREDICATED OF NOTHING ELSE.
It would seem that (physical) "being" is that which is not predicated of anything else;[355] for whiteness and blackness may, for instance, be predicated of some white or black subject. Likewise with the idea of "doubleness";—I mean here not the doubleness which is the opposite of one half, but the doubleness predicated of some subject, as when one says "this wood is double." So also paternity, and science, are attributes of another subject, of which that is said. So space is that which limits, and time that which measures something else. But fire, or wood considered as such, are not attributes. Neither are Socrates, nor composite being (composed of matter and form), nor form which is in the "being," because it is not a modification of any other subject. Indeed, form is not an attribute of matter; it is an element of the combination. "Man" and "form of man" are one and the same thing.[356] Matter also is an element of the combination; under this respect, it may be predicated of a subject, but this subject is identical with itself. On the contrary, whiteness, considered in itself, exists only in the subject of which it may be predicated. Consequently, the thing which exists only in the subject of which it is predicated is not (physical) "being."[356] "Being," on the contrary, is that which is what it is by itself. In case it form part of some subject, then it completes the combination; whose elements exist each in itself, and which are predicated of the combination only in a condition other than that of existing in it. Considered as a part, "being" is relative to something other than itself; but considered in itself, in its nature, in what it is, it is not predicable of anything.[357]
PHYSICAL BEING IS THE PRINCIPLE OF ALL OTHER THINGS.
To be a subject is then a property common to matter, to form, and to the combination. But this function of subject is fulfilled differently by matter in respect to form, and by form in respect to the modifications, and by the combination; or rather, matter is not a subject in respect to form; form is the complement which completes it when it still is only matter, and when it exists only potentially.[358] To speak strictly, form is not in matter; for when one thing forms only a unity with something else, one cannot say that one is in the other (as some accident in its subject). Only when both are taken together do matter and form form a subject for other things;[359] thus Man in general, and a particular man constitute the subject of passive modifications; they are anterior to the actions and consequences which relate to them. "Being" therefore is the principle from which all other things derive, and by which they exist; that to which all passive modifications relate, and from which all actions proceed.[360]
RELATION BETWEEN PHYSICAL AND INTELLIGIBLE TERMS ARE MERELY VERBAL.
5. Such are the characteristics of sense-being. If in any way they also suit intelligible "being," it is only by analogy,[343] or by figure of speech (homonymy).[361] So, for instance, the "first" is so called in respect of the remainder; for it is not absolutely first, but only in respect to the things which hold an inferior rank; far more, the things which follow the first are also called first in respect to those which follow. Likewise, in speaking of intelligible things, the word "subject" is used in a different sense. It may also be doubted that they suffer ("experience"), and it is evident that if they do suffer, it is in an entirely different manner.[362]
