STRANGER: But that of which this is the condition cannot be absolute unity?
THEAETETUS: Why not?
STRANGER: Because, according to right reason, that which is truly one must be affirmed to be absolutely indivisible.
THEAETETUS: Certainly.
STRANGER: But this indivisible, if made up of many parts, will contradict reason.
THEAETETUS: I understand.
STRANGER: Shall we say that being is one and a whole, because it has the attribute of unity? Or shall we say that being is not a whole at all?
THEAETETUS: That is a hard alternative to offer.
STRANGER: Most true; for being, having in a certain sense the attribute of one, is yet proved not to be the same as one, and the all is therefore more than one.
THEAETETUS: Yes.
