PLATO was the Greek philosopher who wrote The Republic in an attempt to explain such topics as justice and the ideal state.

Plato was a Greek philosopher and mathematician  in Classical Greece. He was the founder of the Academy in Athens. He was the founding figure for Western science, philosophy, and mathematics. He was also cited as one of the founders of Western religion and spirituality.

Plato was the innovator of the dialogue and dialectic forms in philosophy. He appears to have been the founder of Western political philosophy with his work in The Republic and Laws.

The Republic is a Socratic dialogue Plato wrote around 380 BCE. It concerns the definition of justice, the order and character of the just city-state and the just man. It discusses the meaning of justice and whether the just man is happier than the unjust man based on the cities they come from. The dialogue also contains discussion on the theory of forms, the immortality of the soul, and the roles of philosopher and poet in the society.
