Plato (c.427-347 BC) stands with Socrates and Aristotle as one of the shapers of the whole intellectual tradition of the West. He founded the Academy in Athens, the first permanent institution devoted to philosophical research and teaching, and theprototype of all Western universities. Plato wrote over twenty philosophical dialogues, appearing in none himself. (Most have Socrates as chief speaker.)
