Socrates

Also wrote nothing, most of what we know about Socrates was written by Plato, and there is a small movement who wonders if Socrates actually existed or whether Socrates was a device invented by Plato to explain certain key concepts and ideas (for ArsMagica fans, Plato tended to write a lot in the form of Disputatio?, often invoking Socrates as the ultimate proponent with withering critiques of his opponent's grounds for contention). --Jumlian, again the worse for wear.
