Meno

Plato's dialogue in which Socrates and Meno investigate whether virtue can be taught — leading to the theory of recollection (anamnesis) as an answer to Meno's paradox about inquiry.

Meno's paradox: you cannot inquire into what you know (you already know it) or what you don't know (you don't know what to look for). Solution: all learning is recollection — the soul pre-existed and knew the Forms; learning is remembering. Virtue is not taught but a divine gift.
