Biography

Aristotle was one of the most influential philosophers in history. He founded his own school — the Lyceum, where he taught while walking with his students (hence 'Peripatetics').

Aristotle systematized virtually all areas of knowledge of his time: logic, physics, biology, ethics, politics, poetics. His logic (syllogistics) remained the foundation of Western logic for over 2000 years.

In ethics, he developed the concept of the 'golden mean' — virtue as the middle ground between extremes.
