That is true.
But then, again, the whole is not in the parts—neither in all the parts, nor in some one of them. For if it is in all, it must be in one; for if there were any one in which it was not, it could not be in all the parts; for the part in which it is wanting is one of all, and if the whole is not in this, how can it be in them all?
It cannot.
Nor can the whole be in some of the parts; for if the whole were in some of the parts, the greater would be in the less, which is impossible.
Yes, impossible.
But if the whole is neither in one, nor in more than one, nor in all of the parts, it must be in something else, or cease to be anywhere at all?
Certainly.
If it were nowhere, it would be nothing; but being a whole, and not being in itself, it must be in another.
Very true.
The one then, regarded as a whole, is in another, but regarded as being all its parts, is in itself; and therefore the one must be itself in itself and also in another.
