Plato b. 428/427 BC, Athens, or Aegina, Greece d. 348/347, Athens Ancient Greek philosopher, the second of the great trio of ancient Greeks Socrates , Plato, and Aristotle who between them laid the philosophical foundations of Western culture . Building on the life and thought of Socrates, Plato developed a profound and wide-ranging system of philosophy. His thought has logical, epistemological, and metaphysical aspects; but its underlying motivation is ethical. It sometimes relies upon conjectures and myth, and it is occasionally mystical in tone; but fundamentally Plato is a rationalist, devoted to the proposition that reason must be followed wherever it leads. Thus the core of Plato's philosophy, resting upon a foundation of eternal Ideas, or Forms, is a rationalistic ethics. Life Plato was born, the son of Ariston and Perictione, in about 428 BC, the year after the death of the great statesman Pericles . His family, on both sides, was among the most distinguished in Athens. Ariston is said to have claimed descent from the god Poseidon through Codrus, the last king of Athens; on the mother's side, the family was related to the early Greek lawmaker Solon . Nothing is known about Plato's father's death. It is assumed that he died when Plato was a boy. Perictione apparently married as her second husband her uncle Pyrilampes, a prominent supporter of Pericles; and Plato was probably brought up chiefly in his house. Critias and Charmides, leaders among the extremists of the oligarchic terror of 404, were, respectively, cousin and brother of Perictione; both were friends of Socrates, and through them Plato must have known the philosopher from boyhood. | |
