_Ibn Rushd_ (A.H. 520-595), known to the West as Averroes, was the greatest of the Arabic philosophers, and was practically their last. He was a native of Cordova and the friend and protégé of Ibn Tufayl, by whom he was introduced to Abu Ya´qub in 548. He was, however, more outspoken than Ibn Tufayl, and wrote several controversial works against al-Ghazali and his followers. The family to which he belonged was one whose members usually became jurists, and Ibn Rushd acted as Qadi in various Spanish towns; like most of the Arabic philosophers he studied medicine, and in 578 was appointed court physician to Abu Ya´qub. By this time he had finished his career as an author. Under the Muwahhid Abu Yusuf al-Mansur he was censured as a heretic and banished from Cordova. It must be remembered that the Muwahhids, like the Murabits, were really Moroccan rulers, to whom Spain was a foreign province. It was whilst the Emir was in Spain and at Cordova, making ready for an attack upon the Christians, that Ibn Rushd was disgraced, and it seems probable that this was mainly a matter of policy, as the Emir, on the eve of a religious war, was desirous of proving his own strict orthodoxy by the public disapproval of one who had been rather too outspoken in his speculative theories. As soon as the Emir returned to Morocco the order of exile was revoked, and later on Ibn Rushd appears at the court of Morocco, where he died in 595. Amongst the Muslims Ibn Rushd has not exercised great influence; it was the Jews who supplied the bulk of his admirers, and they, scattered in Provence and Sicily by Muwahhid persecution, seem to have been chiefly instrumental in introducing him to Latin Christendom.
