Who is Plato from Historical and Philosophical Foundations of Education: A Biographical Introduction and what is their importance?

Plato was an ancient Greek philosopher who is known as an idealist philosopher and a proponent of education for the perfect society. Plato lived from 427-347 B.C.E. in democratic Athens. He developed an educational philosophy unique because of its location in the ancient Greek world on separate islands off the southern tip of the Balkan Peninsula in the Aegean and Ionian Seas. Each island was ruled by its own autonomous, independent city-state that had political and cultural characteristics different from others called "polis" like Thebes, Corinth, Delos, Athens and Sparta. Each self-governing polis promoted growth and participation in democracy with an educated citizenry who debated the nature of a good human being supported by education to reach that goal. Plato's educational philosophy was formulated on the ideal of a republic where a good life may be lived.
