Plato's 'Republic', which was likely completed around 370 BC, is still considered one of the most influential and simultaneously controversial works of Western philosophy. In it, the great Greek thinker outlines the characteristics of a utopian, fundamentally just community, a state that is based on the strict principles of political-philosophical education. Educators, visionaries, and statesmen are the philosophers who are wholly dedicated to the common good and rely on their knowledge of the idea of the Good.
