Plato

ClassicalPlatonist

Born c. 428 BCE, Athens

Died c. 348 BCE, Athens

He saw a world behind the world. The Forms are real; what we see are shadows.

Plato was Socrates’ most devoted student, and after his teacher’s death, he spent years traveling before returning to Athens to found the Academy, the Western world’s first institution of higher learning. His dialogues are philosophy as literature: Socrates arguing about justice, beauty, the good, and the nature of reality itself. His theory of Forms, that the visible world is a reflection of eternal, perfect originals, shaped metaphysics for two millennia.

Works

Apology

c. 399 BCE·Greek

Plato's account of Socrates' defense at his trial. Not an apology in the modern sense but a defiant argument that the examined life is the only life worth living.

Crito

c. 399 BCE·Greek

Socrates sits in prison, awaiting execution. His old friend Crito arrives before dawn to urge him to escape. Socrates refuses, arguing that one must never do wrong, even in return for wrong done to oneself.

Symposium

c. 385 BCE·Greek

A dialogue on the nature of love, told through a series of speeches at a drinking party. Socrates recounts the teachings of Diotima on the ascent from physical beauty to the Form of Beauty itself.

Phaedo

c. 380 BCE·Greek

The dialogue set on the day of Socrates' execution. Contains arguments for the immortality of the soul and the theory of recollection.

Republic

Plato's most influential dialogue, exploring justice, the ideal state, the allegory of the cave, and the theory of Forms. It remains the founding text of political philosophy.

Life & Moments

c. 428 BCE

Born in Athens

Born into one of Athens’ most distinguished families. His real name may have been Aristocles; ‘Plato’ was possibly a nickname meaning ‘broad,’ perhaps for his wrestler’s build or the breadth of his style.

c. 408 BCE

Meeting Socrates

Around age twenty, Plato became a student of Socrates. The encounter changed the course of his life. He would later write that before meeting Socrates, he had planned a career in politics.

399 BCE

Death of Socrates

The execution of his teacher was the defining trauma of Plato’s life. He was reportedly too ill to attend the final hours. The event convinced him that Athens’ democracy was fatally flawed and turned him toward philosophy as a vocation.

c. 388 BCE

First Voyage to Syracuse

Plato traveled to Syracuse hoping to influence the tyrant Dionysius I. The visit ended in disaster. Dionysius, angered by Plato’s frank criticism, reportedly had him sold into slavery. Friends ransomed him and he returned to Athens.

c. 387 BCE

Founding of the Academy

After years of travel, Plato returned to Athens and founded the Academy in a grove sacred to the hero Akademos. It became the Western world’s first institution of sustained intellectual inquiry, lasting nearly nine centuries.

c. 375 BCE

Writing the Republic

Plato composed his masterwork, a dialogue on justice, the ideal state, and the nature of reality. The allegory of the cave, the divided line, and the philosopher-king all appear here. It remains the most influential work of political philosophy ever written.

c. 348 BCE

Death in Athens

Plato died in Athens around age eighty, reportedly while attending a wedding feast. He left the Academy to his nephew Speusippus. The school would continue for centuries after his death.
