The Canon of Medicine is a widely studied medical textbook — it was used at the University of Montpellier as late as 1650. His philosophical system influenced both Islamic and Western thought, shaping the work of al-Ghazali, Ibn Rushd, Thomas Aquinas, and Duns Scotus. He is revered in Iran, Central Asia, and across the Islamic world as a prominent example of the Muslim polymath. His contributions to medicine, philosophy, astronomy, and pharmacology demonstrate his significant role as an intelle…
