The navigator.
Socrates
And who can best superintend the work of the lawgiver and judge of it when it is finished, both here and in foreign countries? The user, is it not?
Hermogenes
Yes.
Socrates
And is not this he who knows how to ask questions?
Hermogenes
Certainly.
Socrates
And the same one knows also how to make replies?
Hermogenes
Yes.
Socrates
And the man who knows how to ask and answer questions you call a dialectician?

Yes, that is what I call him.
