Averroism is a school of Islamic philosophy that arose from the influence of the twelfth century Al-Andalus Muslim philosopher Averroës, who worked on reconciling Aristotelianism with Islam. Alternatively, the term Averroism may refer to the application of these ideas by thirteenth-century scholastic philosophers in the Latin Christian and Jewish intellectual traditions, such as Siger of Brabant, Boetius of Dacia and Maimonides. The term was used by the theologian Thomas Aquinas in a restricted sense to mean monopsychism and radical Aristotelianism.
