But, 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 itself, it is not one with itself,
and will therefore be one and also not one.

Surely that is impossible.

And therefore the one can neither be other than other, nor the same with
itself.

Impossible.

And thus the one can neither be the same, nor other, either in relation to
itself or other?

No.

Neither will the one be like anything or unlike itself or other.

Why not?

Because likeness is sameness of affections.

Yes.
