Born at Stagira, in Thrace, he was a student in Plato's Academy from 367 B.C. to Plato's death in 347 B.C. He was tutor to Alexander of Macedon, 343-340 B.C.

Now where there are ends beyond, in the case of these activities, the ends are regarded as higher than the activities. And since there are many actions and arts and sciences, many also are the ends that arise. For the end of medicine is health; the end of shipbuilding, a vessel;
