Plato

Plato (c. 428–348 BCE) was born into an aristocratic Athenian family. After Socrates’ execution, he traveled widely and later founded the Academy in Athens, one of the first institutions of higher learning in the Western world. His philosophical works are almost entirely written as dialogues, with Socrates as the central figure. The Republic, his most celebrated work, examines the nature of justice and the ideal state, introducing concepts like the philosopher-king and the allegory of the cave. Other major dialogues include Phaedo, Symposium, and Timaeus. Plato’s theory of Forms—the idea that non-material abstract forms represent the highest reality—profoundly influenced subsequent philosophy, theology, and political theory. His literary legacy endures as a cornerstone of Western intellectual tradition.
