Plato
Plato (427–347 B.C.) was a classical Greek philosopher, mathematician, writer, and student of Socrates. Most of his works, which form some of the core foundations of Western philosophy, are written in the form of dialogues, in which Socrates often figures prominently. His best-known writings include the Republic, the Apology, the Symposium, Crito, and Statesman. Plato's work addresses such diverse themes as the nature of love, human knowledge and understanding, and the ideal form of government.
