Plato

Life
Plato was born to an aristocratic family in Athens. His father, Ariston, was believed to have descended from the early kings of Athens. Perictione, his mother, was distantly related to the 6th-century B.C. lawmaker Solon.

When Plato was a child, his father died, and his mother married Pyrilampes, who was an associate of the statesman Pericles.

Plato's original name was Aristocles, but in his school days he received the nickname Platon (meaning "broad" ) because of his broad shoulders.

It was mostly in Pyrilampes' house that Plato was brought up. Aristotle writes that when Plato was a young man he studied under Cratylus who was a student of Heracleitus, famed for his cosmology which is based on fire being the basic material of the universe. It almost certain that Plato became friends with Socrates when he was young, for Plato's mother's brother Charmides was a close friend of Socrates.

The Peloponnesian War was fought between Athens and Sparta between 431 BC and 404 BC.

Plato was in military service from 409 BC to 404 BC but at this time he wanted a political career rather than a military one. At the end of the war he joined the oligarchy of the Thirty Tyrants in Athens set up in 404 BC, one of whose leaders being his mother's brother Charmides, but their violent acts meant that Plato quickly left.

In 403 BC there was a restoration of democracy at Athens and Plato had great hopes that he would be able to enter politics again. However, the excesses of Athenian political life seem to have persuaded him to give up political ambitions.

In particular, the execution of Socrates in 399 BC had a profound effect on him and he decided that he would have nothing further to do with politics in Athens.

Plato left Athens after Socrates had been executed and traveled in Egypt, Sicily and Italy. In Egypt he learned of a water clock and later introduced it into Greece. In Italy he learned of the work of Pythagoras and came to appreciate the value of mathematics. He studied with the disciples of Pythagoras.

Again there was a period of war and again Plato entered military service. It was claimed by later writers on Plato's life that he was decorated for bravery in battle during this period of his life. It is also thought that he began to write his dialogues at this time.

On his return to Athens Plato founded, in about 387 BC, on land which had belonged to Academos, a school of learning which being situated in the grove of Academos was called the Academy.

On his journeys he decided to devote the rest of his life to philosophy.

In 389 B.C. he founded a school in Athens. Because it was on the grounds that had once belonged to a legendary Greek called A cademus, it came to be called the Academy, and this term has been d for schools ever since. The institution often described as the first European university.

The Academy provided a comprehensive curriculum, including such subjects as astronomy, biology, mathematics, political theory, and philosophy.

The main purpose of the Academy was to cultivate thought to lead to a restoration of decent government in the cities of Greece.

Only two further episodes in Plato's life are recorded. He went to Syracuse in 367 BC following the death of Dionysius I who had ruled the city. Dion, the brother-in-law of Dionysius I, persuaded Plato to come to Syracuse to tutor Dionysius II, the new ruler. Plato did not expect the plan to succeed but because both Dion and Archytas of Tarentum believed in the plan then Plato agreed. Their plan was that if Dionysius II was trained in science and philosophy he would be able to prevent Carthage invading Sicily. However, Dionysius II was jealous of Dion who he forced out of Syracuse and the plan, as Plato had expected, fell apart.

Plato returned to Athens, but visited Syracuse again in 361 BC hoping to be able to bring the rivals together. He remained in Syracuse for part of 360 BC but did not achieve a political solution to the rivalry. Dion attacked Syracuse in a coup in 357, gained control, but was murdered in 354.

Like Socrates, Plato was chiefly interested in moral philosophy and despised natural philosophy (that is, science) as an inferior and unworthy sort of knowledge.

To Plato, knowledge had no practical use, it existed for the abstract good of the soul. At the heart of Plato's philosophy is his theory of Forms, or Ideas. Ultimately, his view of knowledge, his ethical theory, his psychology, his concept of the state, and his perspective on art must be understood in terms of this theory.
