A student of Plato was Aristotle.
 Plato gives little biographical information about himself in his works, but often referred some of his relatives with a great degree of precision, including his brothers Adeimantus and Glaucon, who debate with Socrates in the Republic
 Plato's most self-critical dialogue is the Parmenides, which features Parmenides and his student Zeno, which criticizes Plato's own metaphysical theories
