namely the mind, the faculty that fashions universals; and there is no doubt that this fashioning is not one of the inherent properties of the particular. Rather, it is a contingent occurrence that requires a cause separate from concrete realities. Yet calling it “contingent” is not meant to suggest that it subsists in or inheres in the particular; what is intended is that it sometimes accompanies the particular and at other times is absent. Its existence merely coincides with the existence of the particular; it is not a necessary concomitant of it.
Third rejoinder: You say, “If the two agree in existence and necessity, and some other attribute supervenes, then the cause of that attribute must be either the existence and necessity themselves or something external to them,” and so on.
We reply: There is no doubt that they agree in absolute existence and absolute necessity, just as they agree in an absolute quiddity and an absolute essence. Your phrase “some other attribute supervenes upon them” refers to the individuating feature by which each becomes determinate; and there is no doubt that each of them has its own particular individuation and its own particular necessary existence, just as each is said to have its own particular quiddity. Nor is there any doubt that what they share is not the cause of what distinguishes them: the absolute is never the cause of the determinate. For if it were, the presence in the mind of absolute universals would entail the external existence of their concrete instances—an absurdity, just as the converse is absurd. Thus the absolute is neither the cause nor the necessary concomitant of the determinate, nor is the determinate the cause or necessary concomitant of the absolute.
As for your statement that the existence(1) that follows must have a cause, which is either necessary existence itself or something outside it, we say to you: the cause of a determinate necessary existence is likewise the cause of the determinate accident. This by no means entails that a single entity produces disparate effects; rather, that very same entity produces one effect only in its very self. Even though each, together with the other, is one in kind, what proceeds from it is a single effect in kind. In either case
