In one of Plato's seminars a young man with a rural accent stood up one day and said Plato's philosophy was nonsense. You can have ideas that are neither real nor permanent. They can be mere fleeting fantasies. Plato evicted the student, whose name was Aristotle. Unlike Plato, Aristotle was not one of the gilded youth of Athenian society. His social background was solid middle class. But such was the encyclopedic knowledge he came to exhibit, and his skill in logical argument, that in time Aristotle gained rich benefactors, including the king of Macedonia who hired Aristotle to tutor his young son, later known as Alexander the Great.
