Men acquire a particular quality by constantly acting a particular way. You become just by performing just actions, temperate by performing temperate actions brave by performing brave actions.
Aristotle (384–322 BC) was an ancient Greek philosopher and scientist. His writings cover many subjects – including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theater, music, rhetoric, linguistics, politics and government – and constitute the first comprehensive system of Western philosophy. He was Plato's student and Alexander the Great's tutor.
