Pyrrho is almost entirely legend. He travelled east with Alexander's army and the tradition says he met the gymnosophists, the naked philosophers of India, and came back changed; whether that contact shaped the doctrine is argued and unresolved. The anecdotes about his indifference — friends steering him away from carts and cliffs — read as hostile caricature, and Diogenes Laertius also reports that he lived to ninety and was made high priest of his city, which is not the biography of a man who could not cross a road. What is certain is that he wrote nothing, that his pupil Timon of Phlius put him into verse, and that the school which took his name was assembled three hundred years later by people who never met him.
