FIFTH ENNEAD, BOOK SEVEN.
Do Ideas of Individuals Exist?
TWO POSSIBLE HYPOTHESES OF IDEAS OF INDIVIDUALS.
1. Do ideas of individuals (as well as of classes of individuals), exist? This means that if I, in company with some other man, were to trace ourselves back to the intelligible world, we would there find separate individual principles corresponding to each of us. (This might imply either of two theories.) Either, if the individual named Socrates be eternal, and if the soul of Socrates be Socrates himself, then the soul of each individual is contained in the intelligible world. Or if, on the contrary, the individual named Socrates be not eternal, if the same soul can belong successively to several individuals, such as Socrates or Pythagoras, then (as Alcinoous, e. g., and other Platonists insist), each individual does not have his idea in the intelligible world.
THE FIRST (NON-PLATONIC) HYPOTHESIS ALONE RIGHT.
If the particular soul of each man contains (“seminal) reasons” of all the things she does, then each individual corresponds to his idea in the intelligible world, for we admit that each soul contains as many (“seminal) reasons” as the entire world. In this case, the soul would contain not only the (“seminal) reasons” of men but also those of all animals, the number of these reasons will be infinite, unless (as the Stoics teach) the world does not re-commence the identical series of existences in fixed periods; for the only means of limiting the infinity of reasons, is that the same things should reproduce themselves.
DIFFERENCE OF THINGS DEPEND ON THEIR SEMINAL REASONS.
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),1 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 exemple, 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.
(Third objection): What then is the cause of the difference of the individuals conceived in some other place (than the womb, as in the mouth), (as Aristotle2 and Sextus Empiricus3 asked) ? Would it arise from matter being penetrated by the (“seminal) reason” in differing degrees? In this case, all the individuals, except one, would be beings against nature (which, of course, is absurd). The varieties of the individuals are a principle of beauty; consequently, form cannot be one of them; ugliness alone should be attributed to the predominance of matter. In the intelligible world, the (“seminal) reasons” are perfect, and they are not given any less entirely for being hidden.
LEIBNITZ’S DOCTRINE OF THE INDISCERNIBLES.
(Fourth objection) : Granting that the (“seminal) reasons” of the individuals are different, why should there be as many as there are individuals which achieve existence in any one period? It is possible that identical “reasons” might produce individuals differing in external appearance; and we have even granted that this may occur when the (“seminal) reasons” are given entirely. It is asked, is this possible when the same “reasons” are developed? We teach that absolutely similar things might be reproduced in different periods; but, within the same period, there is nothing absolutely identical.
THERE ARE DIFFERENT IDEAS FOR TWINS, BRETHREN. OR WORKS OF ART.
3. (Fifth objection): But how could (“seminal) reasons” be different in the conception of twins, and in the act of generation in the case of animals who procreate multiple offspring? Here it would seem that when the individuals are similar, there could be but one single “reason.” No so; for in that case there would not be so many “reasons” as there are individuals; and, on the contrary, it will have to be granted that there are as many as there are individuals that differ by specific differences, and not by a mere lack of form. Nothing therefore hinders us from admitting that there are different “reasons,” even for animal offspring which show no difference, if there were such. An artist who produces similar works cannot produce this resemblance without introducing in it some difference which depends on reasoning; so that every work he produces differs from the others, because he adds some difference to the similarity. In nature, where the difference does not derive from reasoning, but only from differing (“seminal) reasons” the (individual) difference will have to be added to the specific form, even though we may not be able to discern it. The (“seminal) reason” would be different if generation admitted chance as to quantity (the number of offspring begotten). But if the number of things to be born is determinate, the quantity will be limited by the evolution and development of all the “reasons,” so that, when the series of all things will be finished, another period may recommence. The quantity suitable to the world, and the number of beings who are to exist therein, are things regulated and contained in the principle which contains all the “reasons” (that is, the universal Soul), from the very beginning.
