Aristoteles

Aristotle studied for twenty years under Plato, tutored Alexander the Great, and founded his own school, the Lyceum. He wrote on almost everything: logic, biology, physics, ethics, politics, poetry. Where Plato looked to a perfect world beyond the senses, Aristotle studied this one. In the Nicomachean Ethics he argues that a good life is not a feeling but an activity, and that we become brave, just and temperate by practising those things until they become habit.
