The subject of action gives rise to the following considerations.
ACTUALIZATION A FAR BETTER CATEGORY THAN DOING OR ACTING.
15. The Aristotelians hold that number and quantity, and other things referring to being should be subordinated to being; thus they classify quantity as in a genus different from being. Quality also refers to being, it also is erected into a separate genus. Consequently, as action also refers to being, it is also considered a separate genus. Must then "acting," or rather "action," from which "acting" is derived, be considered a separate genus, as we consider that quality, from which qualification is derived, is a separate genus? (As to these derivations), it might be asked whether there were no distinction between "action," "to act," and "active," or between "to act," and "action?" "To act" expresses the idea of "active," while "action" does not express it. "To act" means "to be in some action;" or rather, "in actualization." Consequently, "actualization" expresses a category rather than "action;" since actualization is predicated of being, like quality, as was said above; and actualization, like movement, also relates to being; but movement necessarily constitutes a class of essence. How indeed could we admit that quantity, quality and relation each form a genus, in respect to being, and yet refuse to movement, which equally refers to being, the privilege of also forming a genus of being?
HOW CAN MOVEMENT BE IN TIME, IF CHANGE BE OUTSIDE OF TIME?
16. It may be objected that movement is an imperfect actualization.[272] In that case actualization should be given the first rank; and under that genus would follow the species of movement, with the quality of imperfection, by saying that movement is an actualization, and adding (the specific difference) that it is imperfect. To say that movement is an imperfect actualization does not deprive it of being an actualization, but implies that though it be actualization, there is in it succession, not to arrive at being actualization, (which it is already), but to accomplish something from which it is yet entirely distinct. Then (when that goal is reached), it is not the movement that becomes perfect, but the thing which was the goal. For instance, walking is walking from the very first step; but if there be a mile to go, and the mile be not yet finished, what is lacking of the mile is not lacking to the walking or to movement (taken absolutely), but to that particular walk. For the walk was walking and movement from the very first step; consequently, he who is moving has already moved, and he who cuts has already cut.[273] Just as actualization, movement has no need of time; it needs time only to become such an action. If then actualization be outside of time, movement, taken absolutely, must also be outside of time. The objection that movement is in time because it implies continuity (proves too much; for in that case) intuition itself, if prolonged, would also imply continuity, and therefore would be in time. Reasoning by induction, it may be seen, 1, that one can always distinguish parts in any kind of movement; 2, that it would be impossible to determine when and since when the movement began, or to assign the definite point of departure; 3, that it is always possible to divide movement by following it up to its origin, so that in this manner movement that has just begun would find itself to have begun since infinite time, and, 4, that movement would be infinite in regard to its beginning. The fact is that the Aristotelians distinguish movement from actualization; they affirm that actualization is outside of time, but that time is necessary to movement; not indeed to some particular movement, but to movement in itself, because, according to their views, it is a quantity. Nevertheless, they themselves acknowledge that movement is a quantity only by accident, as, for instance, when it is a daily movement, or when it has some particular duration. Just as actualization is outside of time, nothing hinders movement from having begun outside of time, and time from being connected with movement only because the movement has a certain duration. Indeed, it is generally granted that changes occur outside of time, for it is usual to say, The changes occur either suddenly or successively. Now if change can occur outside of time, why should it not be so also with movement? We here speak of change, and not of "having changed;" for change does not necessarily have to be accomplished (while "having changed" signifies an accomplished fact, and consequently implies the notion of time).
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.
ON ARISTOTELIAN PRINCIPLES, EVEN INTELLECTION WOULD BE MOVEMENT OR ACTUALIZATION.
18. We must further examine if the Aristotelians have the right to say that acting contains both actualizations and movements, the actualizations producing themselves instantaneously, and the movements successively; as, for instance, dividing implies time. Or will they say that all actualizations are movements, or, at least, are accompanied by movements? Will they trace all actions to "experiencing" (or, reactions), or will they acknowledge absolute actions, like walking or speaking? Or will they distinguish all actions that relate to "experiencing" as movements, and all absolute actions as actualizations? Or will they place actions of both kinds among movements, and among actualizations? They would no doubt classify walking, which is an absolute thing, as movement; and thinking, which is a verb without passive voice, as an actualization.[275] Otherwise the Aristotelians will be obliged to insist that there is nothing active in walking or thinking. But if walking and thinking do not belong to the category of acting, it will be necessary to explain to what they do belong. Will it be said that thinking relates to the thinkable (the intelligible), as intellection does,[276] because sensation relates to the sense-object? If sensation be related to the sense-object, why do they not equally relate "sensing" (feeling) to the sense-object? Sensation, relating to something else, has a relation with that thing; but, besides that relation, it has the property of being an "action" or an "experience" (or, reaction). If therefore reaction (or, suffering), besides belonging to something else, or depending on something else, has the property of itself being something, like actualization, then walking, besides belonging to something else (to the feet), and depending on something else (on the motive power), nevertheless by itself possesses the property of being movement. In this case, it will have to be recognized that intellection, besides being a relation, by itself also is a movement or an actualization.
