Plato was born in 427 BC, a scion of a prominent Athenian family. He received an excellent education and was exposed to the Greek philosophical currents. However, what decisively shaped his moral and spiritual essence was Socrates, with his life, philosophy, and death. The great philosopher was the reason the young Plato turned to philosophy, and the Socratic conceptualization formed the basis for the later development of Plato's theory of Ideas.

Plato profoundly interpreted Socrates as a man and teacher, and expressed his personality in many of his works. He traveled to Egypt, Cyrene, and Greater Greece, where he unsuccessfully attempted to implement his political principles in the organization of the Greek cities of Sicily. In 387 BC, he founded the Academy in Athens, a famous center of philosophy and the Muses, which lasted for almost ten centuries, until the times of Justinian.

Plato dedicated himself to teaching and writing until his death (348 BC). His works, all of which have survived, were classified by Thrasyllus into nine tetralogies. Almost all belong to the genre of dialogue, through which Plato distinguished himself, not only as a leading philosopher but also as a true poet. His teaching stems from the doctrines of Greek thought, Orphism, Pythagoreanism, and Ionian philosophy, and of course, the Socratic discourse, eventually shaping itself, as Plato's personal creation, into a colossal philosophical system.

His philosophy - ethical, ontological, political - is the foundation of global Idealism and has perhaps influenced the thought of all ages more than any other.
