All multitude is posterior to the one.
For if multitude is prior to the one, the one indeed will participate of multitude, but multitude which is prior to the one will not participate of the one, since that multitude existed prior to the subsistence of the one. For it will not participate of that which is not; because that which participates of the one, is one and at the same time not one; but the one will not yet subsist, that which is first being multitude.
It is, however, impossible that there should be a certain multitude, which in no respect whatever participates of the one. Multitude, therefore, is not prior to the one.
But if multitude subsists simultaneously with the one, and they are naturally coordinate with each other; for nothing of time will prevent them being so; neither will the one of itself be many, nor will multitude be one, as being at one and the same time oppositely divided by nature, if neither is prior or posterior to the other. Hence, multitude of itself will not be one, and each of the things that are in it will not be one, and this will be the case to infinity, which is impossible.
Multitude, therefore, according to its own nature, participates of the one, and it will not be possible to assume any thing of it which is not one. For not being one, it will be an infinite consisting of infinites, as has been demonstrated.
Hence, it entirely participates of the one. If, therefore, the one which is of itself one, in no respect participates of multitude, multitude will be entirely posterior to the one; participating indeed of the one, but not being participated by the one.
But if the one also participates of multitude, subsisting indeed as one according to hyparxis, but as not one, according to participation, the one will be multiplied, just as multitude is united on account of the one. The one, therefore, will communicate with multitude, and multitude with the one.
But things which coalesce, and communicate in a certain respect with each other, if indeed they are collected together by something else, that something else is prior to them. But if they themselves collect themselves, they are not opposed to each other.
For opposites do not hasten to each other. Hence, if the one and multitude are oppositely divided, and multitude so far as multitude is not one, and the one so far as one is not multitude, neither will one of these subsisting in the other be one and at the same time two.
If, also, there is something prior to them which collects them, this will either be one, or not one. But if it is not one, it will either be many or nothing.
It will not however be many, lest multitude should be prior to the one, nor yet will it be nothing. For how can nothing congregate?
It is, therefore, one alone. For this which is the one cannot be many, lest there should be a progression to infinity.
It is, therefore, the one itself, and all multitude is from the one itself.
