Certainly.
And if I speak of being and the other, or of the one and the other,—in any such case do I not speak of both?
Yes.
And must not that which is correctly called both, be also two?
Undoubtedly.
And of two things how can either by any possibility not be one?
It cannot.
Then, if the individuals of the pair are together two, they must be severally one?
Clearly.
And if each of them is one, then by the addition of any one to any pair, the whole becomes three?
