Born circa 428 B.C., ancient Greek philosopher Plato was a student of Socrates and a teacher of Aristotle. His writings explored justice, beauty and equality, and also contained discussions in aesthetics, political philosophy, theology, cosmology, epistemology and the philosophy of language. Plato founded the Academy in Athens, one of the first institutions of higher learning in the Western world. He died in Athens circa 348 B.C.
Due to a lack of primary sources from the time period, much of Plato's life has been constructed by scholars through his writings and the writings of contemporaries and classical historians. Traditional history estimates Plato's birth was around 428 B.C., but more modern scholars, tracing later events in his life, believe he was born between 424 and 423 B.C. Both of his parents came from the Greek aristocracy. Plato's father, Ariston, descended from the kings of Athens and Messenia. His mother, Perictione, is said to be related to the 6th century B.C. Greek statesman Solon.
