Plato
Plato was a classical Greek philosopher and student of Socrates who founded the Academy in Athens, one of the earliest institutions of higher learning in the Western world.
Watching his own teacher be executed by the city he lived in shaped much of what Plato would go on to write about justice, government, and the ideal society for the rest of his life.
Student of Socrates
Plato was a devoted student of Socrates, and Socrates's execution in 399 BCE profoundly shaped Plato's subsequent philosophical work, much of which he wrote as dialogues featuring his teacher as the central figure exploring difficult questions of ethics, politics, and metaphysics.
The Theory of Forms
Plato developed his influential Theory of Forms, arguing that abstract, unchanging ideas or "forms" represent a higher, truer reality than the imperfect physical world perceived through the senses — a concept that would influence Western philosophy for millennia.
The Republic
Plato's most famous and enduring work, The Republic, explores the nature of justice and describes his vision of an ideal society governed by philosopher-kings, individuals whose wisdom and virtue would qualify them uniquely to rule.
Founding the Academy
Around 387 BCE, Plato founded the Academy in Athens, an institution where students studied philosophy, mathematics, and science for centuries after his death, making it one of the most influential centers of learning in ancient history.
Teaching Aristotle
Among Plato's most notable students at the Academy was Aristotle, who would go on to become one of history's most influential thinkers in his own right, extending and ultimately diverging from many of his teacher's philosophical positions.
