Besides, we have elsewhere pointed out[315] that what is a complement of being is called a quality figuratively only;[306] and that what is genuinely quality comes from the exterior, posteriorly to being. What properly belongs to being is its actualization; and what follows it is an experience (or, negative modification). We now add that what refers to some being, cannot in any respect be the complement of being. There is no need of any addition of "being" (existence) to man, so far as he is a man, to make of him a (human) being. Being exists already in a superior region before descending to specific difference; thus the animal exists (as being) before one descends to the property of being reasonable, when one says: "Man is a reasonable animal."[316] THE FOUR OTHER CATEGORIES DO NOT TOGETHER FORM QUALITY. 15. However, how do four of these genera complete being, without nevertheless constituting the suchness (or, quality) of being? for they do not form a "certain being." The primary Essence has already been mentioned; and it has been shown that neither movement, difference, nor identity are anything else. Movement, evidently, does not introduce any quality in essence; nevertheless it will be wise to study the question a little more definitely. If movement be the actualization of being, if essence, and in general all that is in the front rank be essentially an actualization, movement cannot be considered as an accident. As it is, however, the actualization of the essence which is in actualization, it can no longer be called a simple complement of "being," for it is "being" itself. Neither must it be ranked amidst things posterior to "being," nor amidst the qualities; it is contemporaneous with "being," for you must not suppose that essence existed first, and then moved itself (these being contemporaneous events). It is likewise with stability; for one cannot say that essence existed first, and then later became stable. Neither are identity or difference any more posterior to essence; essence was not first unitary, and then later manifold; but by its essence it is one manifold. So far as it is manifold, it implies difference; while so far as it is a manifold unity, it implies identity. These categories, therefore, suffice to constitute "being." When one descends from the intelligible world to inferior things, he meets other elements which indeed no longer constitute absolute "being," but only a "certain being," that possesses some particular quantity or quality; these are indeed genera, but genera inferior to the primary genera. RELATION IS AN APPENDAGE EXISTING ONLY AMONG DEFINITE OBJECTS. 16. As to relation, which, so to speak, is only an offshoot or appendage,[317] it could certainly not be posited amidst the primary genera. Relation can exist only between one thing and another; it is nothing which exists by itself; every relation presupposes something foreign. NEITHER CAN PLACE OR TIME FIGURE AMONG THEM.[318]
