But perhaps the motion of the one consists in going from one place to another?
Perhaps so, if it moves at all.
And have we not already shown that one can not be in anything?
Yes.
And still greater is the impossibility of one coming into being in anything?
I do not see how that is.
Why, because anything which comes into being in anything, cannot as yet be in that other thing while still coming into being, nor remain entirely out of it, if already coming into being in it.
Certainly.
And therefore whatever comes into being in another must have parts, and the one part may be in that other, and the other part out of it; but that which has no parts cannot possibly be at the same time a whole, which is either within or without anything.
True.
