Who wrote "The Republic"?
Plato (428/427 or 424/423 – 348/347 BC) was an Athenian philosopher during the Classical period in Ancient Greece, founder of the Platonist school of thought, and the Academy, the first institution of higher learning in the Western world. He is widely considered the pivotal figure in the history of Ancient Greek and Western philosophy, along with his teacher, Socrates, and his most famous student, Aristotle. Plato has also often been cited as one of the founders of Western religion and spirituality.
Plato was the innovator of the written dialogue and dialectic forms in philosophy. Plato also appears to have been the founder of Western political philosophy. His most famous contribution bears his name, Platonism (also ambiguously called either Platonic realism or Platonic idealism), the doctrine of the Forms known by pure reason to provide a realist solution to the problem of universals. He is also the namesake of Platonic love and the Platonic solids.
The Republic is a Socratic dialogue, written by Plato around 380 BC, concerning justice, the order and character of the just city-state, and the just man. It is Plato's best-known work, and has proven to be one of the world's most influential works of philosophy and political theory, both intellectually and historically.
