The works of Averroes belong to the heritage of both East (dar al-Islam) and West (orbis christianorum). In the circle of Muslim culture he has become the representative of the Andalusian rationalism. He tried to enter the Aristotelian discourse on the exegesis of the Qur’an and to show that philosophy is contained in the holy book of Islam. Particularly important was the methodology for arriving at the truth by demonstration which is the highest form of logical deduction. Averroes tried to argue that because the Quran contains everything, it also includes philosophy. He used verses of the Quran as premises in syllogistic evidence. His solutions were interesting but finally have been marginalized by the Muslim orthodoxy and he was banished. In the West, Averroes was known as a commentator of Aristotle. However, his original works were little known. In his commentary on the De Anima some medieval thinkers have found a few controversies. The most important of these were the theory of monopsychism, recognition of determinism and eternity of the world and the negation of God’s providence. Recent studies on the works of Averroes have shown that the many allegations made against him were not sufficient justification against his works. Controversy over Averroes show that he is a tragic figure. Although he could have become a bridge between East and West, he was rejected by both parties.
