When my sons are grown up, I would ask you, O my friends, to punish them; and I would have you to trouble them, as I have troubled you, if they seem to care about riches, or anything, more than about virtue; or if they pretend to be something when they are really nothing — then reprove them, as I have reproved you, for not caring about that for which they ought to care, and thinking that they are something when they are really nothing. And if you do this, I and my sons will have received justice at your hands.

41e–42a - Plato - Apology
