Aristotelianism Aristotelianism ( ) is a tradition of philosophy that takes its defining inspiration from the work of Aristotle. This school of thought is in the modern sense of philosophy, covering existence, ethics, mind and related subjects. In Aristotle's time, philosophy included natural philosophy, which was replaced by modern science during the Scientific Revolution. The works of Aristotle were initially defended by the members of the Peripatetic school and later on by the Neoplatonists, who produced many commentaries on Aristotle's writings. In the Islamic Golden Age, Ibn Sina and Ibn Rushd translated the works of Aristotle into Arabic and under philosophers such as Al-Kindi, Al-Farabi, Avicenna and Averroes, Aristotelianism became a major part of early Islamic philosophy.
Ibn Zuhr Ibn Zuhr (Arabic: ‎ ‎ ; 1094–1162), traditionally known by his Latinized name of Avenzoar, was a Muslim Arab physician and surgeon and poet. He was born at Seville in medieval Andalusia (present-day Spain), was a contemporary of Averroes and Ibn Tufail, and was the most well-regarded physician of his era. He was particularly known for his emphasis on a more rational, empiric basis of medicine. His major work, "Al-Taysīr fil-Mudāwāt wal-Tadbīr" ("Book of Simplification Concerning Therapeutics and Diet"), was translated into Latin and Hebrew and was influential to the progress of surgery. He also improved surgical and medical knowledge by keying out several diseases and their treatments.
