Plato
From Epicurus Wiki
Plato [Πλάτων, "wide, broad-shouldered"] (428/427 BCE - 348/347 BCE), whose original name was Aristocles, was an ancient Greek Philosopher. He was a student of Socrates and a teacher of Aristotle.
Epicurus derides Plato as "Golden" in reference to his undemocratic divisions of men into classes.
