ARISTOTLE (384-322 BC) studied at the Academy of Plato for 20 years and then established his own school and research institute 'The Lyceum'. His writings, which were of extraordinary range, profoundly affected the whole course of ancient and medieval philosophy and are still eagerly studied and debated by philosophers today.
