Plato (c. 427-347 BCE) was one of the central figures in the development of Western philosophy. A student of Socrates and the teacher of Aristotle, Plato founded the Academy in Athens, one of the earliest institutions devoted to philosophical study.Plato wrote a series of philosophical dialogues in which ideas are explored through conversation between Socrates and other interlocutors. These works address a wide range of subjects including ethics, politics, metaphysics, epistemology, and the nature of knowledge.Among his most influential writings are The Republic, Symposium, Phaedo, and Timaeus. Through these dialogues Plato shaped the course of philosophical thought for more than two millennia, influencing traditions of philosophy, theology, and political theory throughout the Western world.
