Plato (c. 428 – 348 BC) was an ancient Greek philosopher and the founder of the Academy in Athens, the first institution of higher learning in the Western world. A student of Socrates and teacher of Aristotle, he shaped Western philosophy with his dialogues and theories on politics, ethics, and metaphysics.
His most influential idea, the Theory of Forms, proposed that the physical world is a mere reflection of eternal, perfect ideals. His works, including The Republic, Symposium, and Phaedrus, explored justice, love, and the nature of knowledge. The Republic introduced the concept of philosopher-kings and outlined his vision of an ideal society.
Plato’s influence extended beyond philosophy, impacting early Christian, Islamic, and Renaissance thought. His dialogues remain foundational texts in education, politics, and ethics. His legacy as one of history’s greatest thinkers endures through his writings and their ongoing relevance.
