But, if produced things may be more numerous than their specimens, what would be the necessity for the "reasons" and specimens of all individuals begotten during some one period? It would seem that the (idea of) the "man himself" to explain the existence of all men, and that the souls of a finite number of them could successively animate men of an infinite number. (To this contention we demur: for) it is impossible for different things to have an identical ("seminal) reason." The (idea of) the man himself would not, as model, suffice (to account) for men who differ from each other not only by matter, but also by specific differences. They cannot be compared to the images of Socrates which reproduce their model. Only the difference of the ("seminal) reasons" could give rise to individual differences. (As Plato said),[334] the entire period contains all the ("seminal) reasons." When it recommences, the same things rearise through the same "reasons." We need not fear that, as a consequence, there would be an infinite (number or variety) of them in the intelligible world; for the multitude (of the seminal reasons) constitutes an indivisible principle from which each issues forth whenever active. SEX ALONE WOULD NOT ACCOUNT FOR THIS DIVERSITY. 2. (First objection): The manner in which the ("seminal) reasons" of the male and female unite, in the act of generation, suffices to account for the diversity of individuals, without implying that each of them possesses its own ("seminal) reason." The generating principle, the male, for example, will not propagate according to different ("seminal) reasons," since it possesses all of them, but only according to its own, or those of its father. Since it possesses all of the ("seminal) reasons," nothing would hinder it from begetting according to different "reasons," only, there are always some which are more disposed to act than are others. EXPLANATION OF THE DIVERSITY FROM SAME PARENTS (Second objection): Please explain how differing individuals are born from the same parents. This diversity, if it be anything more than merely apparent, depends on the manner in which the two generating principles concur in the act of generation; at one time the male predominates, at other times, the female; again, they may both act equally. In either case, the ("seminal) reason" is given in its entirety, and dominates the matter furnished by either of the generating principles. VARIETY MAY DEPEND ON THE LATENCY OF PART OF SEMINAL REASONS.
