Aristotle Born in 384 BC, Aristotle was not a native Athenian, but he lived half his life in that city. He was a pupil of Plato and was a member of Plato's Academy for 20 years. This is one of Aristotle's three treatises on moral science, named after his son, Nichomachus, who died in battle while still young. It is concerned with the study of man's ethos or character as a means to discover in what mode of life man's happiness consists.
