Aristotle (384–322 b.c.) was a Greek philosopher, scientist, and physician. At age twenty-one, he became a student under Plato in Athens. In 342, he became the tutor of young Alexander the Great in Macedonia. After that, Aristotle returned to Athens to establish his own school and research institute, the Lyceum. His writings have profoundly affected the whole course of philosophy, from ancient times to the present.
