Abu al-Hassan Muhammad ibn Yusuf al-Amiri was a Muslim theologian and philosopher who attempted to reconcile philosophy with religion, and Sufism with conventional Islam. While al-'Amiri believed the revealed truths of Islam were superior to the logical conclusions of philosophy, he argued that the two did not contradict each other. Al-'Amiri consistently sought to find areas of agreement and synthesis between disparate Islamic sects. However, he believed Islam to be morally superior to other religions, specifically Zoroastrianism and Manicheism.
