8. The above digression gives us the opportunity of investigating why there should be a difference between these relations, and those of which we spoke above. However, we should be glad to have the Aristotelians first state what community of existence obtains in this correlation. It would be impossible to claim that this community was anything corporeal. If then it be corporeal, it must exist either within the very subjects, or without them. If such a habituation be identical among all, it is a synonym. If it be a habituation which differs according to the subjects in which it exists, it is a homonym; for the mere name of "habituation" (in different things) does not always correspond to the existence of any genuine similarity. Should we then divide the habituations into two classes, recognizing that certain objects have an inert and inactive habituation, implying simultaneity of existence, and that other objects have a habituation always implying "potentiality" and "actualization," so that before "actualizing" the "potentiality" be already ready to exert itself, and to pass from "potentiality" to "actualization" in the approximation of relative conditions? Must we assert that in general certain things actualize, while others limit themselves to existing? Must we also assert that that which limits itself to existence only gives its correlative a name, while that which actualizes gives it existence? Of this latter kind of things are the father and son, the "active" and "passive," for such things exert a kind of life and action. Must we then divide habituation in several kinds, not as possessing something similar and common in the differences, but as having a nature different in each member of the division, and thus constituting a "homonym" (or, mere verbal label)? In this case, we would apply to the active habituation the names of "doing" and "suffering," because both imply an identical action. Further, we will have to posit another "habituation" which, without itself actualizing, implies something which acts in two relative terms. For example, there is equality; which equates two objects; for it is equality which renders things equal, just as identity makes them identical; just as the names "great" and "small" are derived one from the presence of greatness, and the other from that of smallness. But if we should consider greatness and smallness in the individuals which participate therein, it must be acknowledged that such individual is greater by the act of greatness which manifests in him, and that another is smaller because of the inherent act of littleness. HABITUATIONS ARE REASONS THAT PARTICIPATE IN FORMS.
