And this may serve for an answer to those that wonder at our dividing Nature, subject to generation and alteration, into so many kinds. But I entreat you all further, attentively to consider with yourselves that, of the two first and supreme principles of all things,—that is to say, the unity, and the indefinite binary or duality,—this latter, being the element and chief origin of all deformity and disorder, is termed infinity, and on the contrary, the nature of unity, determining and limiting the void infinity, which has no proportion nor termination, reduces it into form, and renders it in some manner capable of receiving a denomination which belongs only to sensible and particular things. Now these two general principles appear first in number; for the multitude is indeed no number, unless a certain form of the matter resulting out of indeterminate infinity is cut off, and bounded within respective limits, either shorter or longer. For then each multitude is made number, when once it is determined and limited by unity; whereas, if we take away unity, then the indeterminate duality brings all into confusion, and renders it without harmony, without number or measure. Now, the form not being the destruction of matter, but rather the order and the beauty of it, both these principles therefore must be within number, from whence ariseth the chief disparity and greatest difference. For the infinite and indeterminate principle is the cause of the even number; and the other better principle, which is the unity, is the father (as it were) of the odd number. So that the first even number is two, and the first odd number is three; of which is composed five by conjunction, which is by its composition common to both, but of power or nature not even but odd. For, since sensible and corporeal nature is divided into several parts, on account of its inborn necessity of diversity, it was necessary that the number of these parts should not be either the first even number, nor yet the first uneven or odd, but a third, consisting of both; to the end that it might be procreated out of both principles, viz. of that which causeth the even number, and of that which produceth the odd; for the one cannot be parted from the other, inasmuch as both have the nature, power, and force of a principle. These two principles being then joined together, the better one being mightier prevails over the indeterminate infinity or duality, which divideth the corporeal nature; and thus the matter being divided, the unity interposing itself between has hindered the universe from being divided and parted into two equal portions. But there has been a multitude of worlds caused by the diversity and disagreement of the infinite Nature; but this multitude was brought into an odd number by the virtue and power of identity, or the finite principle; and it was therefore odd, because the better principle would not suffer Nature to stretch itself further than was fitting. For if there had been nothing but pure and simple unity, the matter would have known no separation; but being mixed with the dividing nature of duality, it has by this means suffered separation and division; yet it has stopped here, by the odd numbers being the superior and master to the even.
