Aristotle was born in the Macedonian city of Stagira in 384 BC, and died in 322. He studied in Plato's Academy in Athens and later became tutor to Alexander the Great, before establishing his own school in Athens, called the Lyceum. His writings, which were of extraordinary range, profoundly affected the whole course of ancient, medieval and modern philosophy. Many of them have survived, including The Nicomachean Ethics, The Politics and Poetics, among others. Adam Beresford is Associate Professor of Philosophy at the University of Massachusetts, Boston. He has previously translated Plato's Protagoras and Meno for Penguin Classics.
