Aristotle (Stagira, Macedonia, 384 BC – Chalicis, Euboea, Greece, 7 March 322 BC) was a Greek philosopher. He was one of the most important philosophers in the history of Western civilization. It is said that Aristotle wrote many books, but only a much smaller number survive. Aristotle was the boyhood tutor of Alexander the Great, who later sent him plants and animals from parts of his new empire.
