That which becomes the same with the many necessarily becomes many and not one.
True.
And yet, if there were no difference between the one and the same, when a thing became the same, it would always become one; and when it became one, the same.
Certainly.
And, therefore, if one be the same with one, it is not one with one, and will therefore be one and also not one.
But that is surely impossible.
And therefore the one can neither be other of other, nor the same with one.
Impossible.
And thus one is neither the same, nor other, in relation to itself or other?
No.
