Article Summary

While philosophical activity in the Islamic west virtually ceased after Ibn Rushd at the close of the sixth century AH (twelfth century ad), it experienced renewed vigour in the east through the intellectual efforts and political involvement of Nasir al-Din al-Tusi. Although primarily a reviver of the peripatetic tradition of Ibn Sina, he was also possibly influenced by the ideas of al-Suhrawardi. He defended Ibn Sina from the criticisms levelled against him from the direction of theology, notably by Fakhr al-Din al-Razi, made a significant contribution to the acceptance of metaphysical argumentation and terminology in Twelver Shi‘i theology, brought the ethical tradition of Ibn Miskawayh and the philosophers into the centre of Islamic ethical discourse, and had a lasting effect on the study of the exact sciences in Islam through both his original contributions to mathematics and astronomy and the observatory at Maraghah which the Mongol Khan Hülegü established for him.
