MENO: Certainly there are.

SOCRATES: And are they willing to teach the young? and do they profess to
be teachers? and do they agree that virtue is taught?

MENO: No indeed, Socrates, they are anything but agreed; you may hear them
saying at one time that virtue can be taught, and then again the reverse.

SOCRATES: Can we call those teachers who do not acknowledge the
possibility of their own vocation?

MENO: I think not, Socrates.

SOCRATES: And what do you think of these Sophists, who are the only
professors? Do they seem to you to be teachers of virtue?

MENO: I often wonder, Socrates, that Gorgias is never heard promising to
teach virtue: and when he hears others promising he only laughs at them;
but he thinks that men should be taught to speak.

SOCRATES: Then do you not think that the Sophists are teachers?

MENO: I cannot tell you, Socrates; like the rest of the world, I am in
doubt, and sometimes I think that they are teachers and sometimes not.

SOCRATES: And are you aware that not you only and other politicians have
doubts whether virtue can be taught or not, but that Theognis the poet says
the very same thing?
