Avicennism is a school in Islamic philosophy which was established by Avicenna. According to Henry Corbin and Seyyed Hossein Nasr, there are two kind of Avicennism: Islamic or Iranian Avicennism, and Latin Avicennism. According to Nasr, the Latin Avicennism was based on the former philosophical works of Avicenna. This school followed the Peripatetic school of philosophy and tried to describe the structure of reality with a rational system of thinking. In the twelfth century AD, It became influential in Europe, particularly in Oxford and Paris, and affected some notable philosophers such as Thomas Aquinas, Roger Bacon and Duns Scotus. While the Latin Avicennism was weak in comparison with Latin Averroism, according to Étienne Gilson there was a "Avicennising Augustinism". On the other hand, Islamic Avicennism is based on his later works which is known as "The oriental philosophy" (حکمت المشرقیین). Therefore, philosophy in the eastern Islamic civilization providing became close to gnosis and tried to provide a vision of spiritual universe. This approach paved the road for the Iranian school of Illuminationism (حکمت الاشراق) by Suhrawardi.
Henry Corbin referred to divergent between Iranian Avicennism and Latin Avicennism. Beside he showed that we can see three different schools in Avicennism. He called them Avicennism Augustinism, Latin Avicennism and Iranian Avicennism.
