Bust of Aristotle. Marble, Roman copy after a Greek bronze original by Lysippos from 330 BC; the alabaster mantle is a modern addition.
Aristotle
Aristotle (384 BC – 322 BC) was the most important of the philosophers of antiquity. He wrote on physics, metaphysics, biology, zoology, logic, linguistics, ethics, politics, government, poetry, theatre, rhetoric, and music, creating the first comprehensive system of Western philosophy. His work included the first known formal theory of logic, which was unsurpassed until the early modern period and, decisively, by Frege's investigations in the late nineteenth century.
