Aristotle (384-322 B.C.) was an ancient Greek philosopher. His writings cover many subjects – including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theater, music, rhetoric, linguistics, politics and government – and constitute the first comprehensive system of Western philosophy. His works contain the earliest known formal study of logic, which was incorporated in the late 19th century into modern formal logic. All aspects of Aristotle's philosophy continue to be the object of active academic study today.
- Aristotle was the subject of the the Sandro di Garagiola fresco, Pope Sporus Debating with Aristotle (Saint Fidgeta and Other Parodies, 57).
