Aristotle was born at Stagira, in the dominion of the kings of Macedonia, in 384 BC. For twenty years he studied at Athens in the Academy of Plato. However he left on Plato's death and, some time later, became the tutor of young Alexander The Great.His writings have profoundly affected the whole course of ancient and medieval philosophy, and they are still studied and debated today.
