Plato (c. 427-347 BC) was born into a wealthy and aristocratic Athenian family. He cherished the ambition of entering politics when he came of age, but was disillusioned first by the injustices of the oligarchic government in which his relatives Charmides and Critias were involved, and later by the action of the democracy which succeeded it, particularly the trial and execution of Socrates in 399 BC. In his best-known dialogue, The Republic, he sought to provide a theoretical foundation for a (...) government which would embody the justice he had found to be lacking in the actual governments of his day. His only active intervention in politics, in the intended role of adviser, was an unsuccessful one in Syracuse, Sicily. Details of it are given in his Seventh Letter. Some time before his second visit to Sicily, in 367 BC, he founded the school known as ‘the Academy’. His career as a writer of dialogues may have begun before this. In his early dialogues, he memorialized Socrates and his method of philosophizing by making him chief participant and questioner. His teaching in the Academy was interrupted for a third visit to Sicily in 361-360 BC, when he was nearly seventy. He survived an illness caused by the hardships of the journey, and died aged about eighty-one. (shrink)
