ACTION AND EXPERIENCING MAY BE SUBSUMED UNDER MOVEMENT, BUT CANNOT BE CONSIDERED AS SEPARATE CATEGORIES.
17. It may be objected that actualization and movement do not, by themselves, form a genus, but belong to the genus of relation, because actualization exists through the power of something active, and movement exists by the power of some motor, as such. We might answer that relative conceptions are produced by habituation (the manner of being) even of things, and not only through the relation established between them by the mind. As the habituation is a mode of "hypostatic" existence, although it be the "thing of something else," or although it refer to something else,[274] it nevertheless possesses its nature before being a relation. Now this actualization, this movement, this habituation, which is the "thing of some other thing" nevertheless possesses the property of existing and of being conceived by itself before being a relation; otherwise, all things would be relative conceptions; for there is nothing, not excluding the soul herself, which does not bear some relation to something else. Moreover, why are "action" and "acting" not relatives? For they necessarily are either a movement or an actualization. If the Aristotelians consider "action" a relative, and make a genus of "acting," why then do they not also place "movement" among the relatives, and make a genus of "moving?" They might, indeed, have subsumed under the genus "movement" the two species "action" and "reaction" (or, "suffering"); but they have no right to make two distinct genera of "acting" and "reacting," as they generally do.
