Theaetetus
THEAET. May be.
Socrates
SOC. Now through what organ do you think all this about them? For it is impossible to grasp that which is common to them both either through hearing or through sight. Here is further evidence for the point I am trying to make: if it were possible to investigate the question whether the two, sound and color, are bitter or not, you know that you will be able to tell by what faculty you will investigate it, and that is clearly neither hearing nor sight, but something else.
Theaetetus
THEAET. Of course it is,—the faculty exerted through the tongue.
Socrates
SOC. Very good. But through what organ is the faculty exerted which makes known to you that which is common to all things, as well as to these of which we are speaking—that which you call being and not-being, and the other attributes of things, about which we were asking just now? What organs will you assign for all these, through which that part of us which perceives gains perception of each and all of them?

Theaetetus
THEAET. You mean being and not-being, and likeness and unlikeness, and identity and difference, and also unity and plurality as applied to them. And you are evidently asking also through what bodily organs we perceive by our soul the odd and the even and everything else that is in the same category.
Socrates
SOC. Bravo, Theaetetus! you follow me exactly; that is just what I mean by my question.
