After this however, let us discuss each of them, beginning according to nature. First, therefore, the intelligible, and at the same time, intellectual number presents itself to our view; and which is connected with multitude. For every number is multitude. But with respect to multitude, one kind subsists unitedly, and another kind with separation. Number, however, is separate multitude; for there is difference in it. For in the intelligible there was power, and not difference, and this power generated multitude, and conjoined it to the monads. Number therefore is in continuity with intelligible multitude; and this is necessary. For the monad was there, and also the duad; since whole also was there, and was always monadic; and becoming to be two, has no cessation. Hence the monad and the duad were there, which are the first and exempt principles of numbers. And in these multitude was unitedly; since the monad which is the fountain of numbers, and the duad possess all multitude according to cause; the former paternally, but the latter maternally. And on this account intelligible multitude is not yet number, but is intelligibly established in the uniform principles, I mean the monad and the duad; generatively indeed, in the duad, but paternally in the monad. For the third God was father and mother; since if animal itself is in it, it is also necessary that the cause of the male and the female should there primarily preexist. For these are in animals. Hence according to Timæus, and according to Parmenides, the maternal and the paternal cause are there. And in these, intelligible animals, and intelligible multitudes are comprehended. From these first principles also number together with difference proceed, and they generate the monads and the duads which are in number, and all numbers. For both the generative and the paternal subsist in these in a feminine manner.
