Socratic ignorance in Plato's Dialogues

Greek philosopher Socrates (469-399 BCE) is associated with humility regarding what one knows. In Plato's dialogues, Socrates is shown to challenge someone who thinks they know something, but when questioned thoroughly about it, turns out not to understand at all. By contrast, Socrates admits from the start that he does not know the answer.

In the Meno (a Socratic dialogue by Plato), Socrates is asked by Meno if virtue can be taught. Socrates responds that he doesn't know what virtue is. In a later part of the dialogue, Socrates shows that an essential step to learning anything is to clear one's mind of false ideas, even if you seem ignorant.
