Plato was a classical Greek philosopher born in 427 BC who founded the Academy in Athens. He was a student of Socrates and wrote works such as The Republic, The Statesman, and The Laws. Plato believed justice could be achieved through education by developing both the mind and soul. He proposed a state-controlled education system that educated both men and women and incorporated aspects of Athenian and Spartan models. The system involved compulsory education from birth through advanced studies focused on subjects like logic, math, and astronomy with the goal of creating a philosopher king to rule justly.
