Of course.
And when we put them together shortly, and say 'One is,' that is equivalent to saying, 'partakes of being'?
Quite true.
Once more then let us ask, if one is what will follow. Does not this hypothesis necessarily imply that one is of such a nature as to have parts?
How so?
In this way:—If being is predicated of the one, if the one is, and one of being, if being is one; and if being and one are not the same; and since the one, which we have assumed, is, must not the whole, if it is one, itself be, and have for its parts, one and being?
Certainly.
And is each of these parts—one and being—to be simply called a part, or must the word 'part' be relative to the word 'whole'?
The latter.
Then that which is one is both a whole and has a part?
