Plato
Plato (known in many traditions as Aflatoon) was born around 427 BCE into an aristocratic family in Athens and became one of the most influential philosophers in Western history. A devoted student of Socrates, he immortalized his teacher’s ideas through a series of dialogues in which Socratic questioning drives the search for truth. Around 387 BCE, Plato founded the Academy, the earliest known institution of higher learning, where he taught for the rest of his life. His philosophical system—most famously articulated in works like The Republic—introduced the Theory of Forms, positing that the visible world is only a shadow of a higher, unchanging reality of perfect ideas. In ethics and politics, Plato argued that justice and virtue arise when individuals and societies align their souls with reason. Beyond metaphysics, his writings span subjects such as knowledge, love, and aesthetics, laying the groundwork for centuries of philosophical inquiry. Plato died around 347 BCE, but his Academy endured for nearly a millennium, and his dialogues continue to shape how we understand knowledge, reality, and the ideal state.
