Plato
Disciple of Socrates who founded the Academy in Athens and wrote dialogues such as the Republic, setting out the theory of Forms and rule by philosopher-kings
Born into an Athenian aristocratic family, he became a disciple of Socrates, and his teacher’s execution turned him against democracy. Around 387 BC he founded the Academy outside Athens, a community of learning that lasted more than nine hundred years. He held that beyond the world of the senses lie the Forms, the true reality, and argued in the Republic that philosophers who know the Forms should rule. Most of his works are dialogues in which Socrates speaks.
