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
