In Plato’s Phaedrus (dialogue), Socrates uses the maxim ‘know thyself’ as his explanation to Phaedrus for why he has no time for mythology or other far flung topics. Socrates says, “But I have no leisure for them at all; and the reason, my friend, is this: I am not yet able, as the Delphic inscription has it, to know myself; so it seems to me ridiculous, when I do not yet know that, to investigate irrelevant things.”
