NECESSITY OF THE EXISTENCE OF THE FIRST.
1. Everything that exists after the First is derived therefrom, either directly or mediately, and constitutes a series of different orders such that the second can be traced back to the First, the third to the second, and so forth. Above all beings there must be Something simple and different from all the rest which would exist in itself, and which, without ever mingling with anything else, might nevertheless preside over everything, which might really be the One, and not that deceptive unity which is only the attribute of essence, and which would be a principle superior even to being, unreachable by speech, reason, or science. For if it be not completely simple, foreign to all complexity and composition, and be not really one, it could not be a principle. It is sovereignly absolute only because it is simple and first. For what is not first, is in need of superior things; what is not simple has need of being constituted by simple things. The Principle of everything must therefore be one and only. If it were admitted that there was a second principle of that kind, both would constitute but a single one. For we do not say that they are bodies, nor that the One and First is a body; for every body is composite and begotten, and consequently is not a principle; for a principle cannot be begotten.[186] Therefore, since the principle of everything cannot be corporeal, because it must be essentially one, it must be the First.
