During the Middle Ages, philosophy itself was in many places seen as opposed to the prevailing monotheistic religions, Islam, Christianity and Judaism. The strongest philosophical tradition for some centuries was amongst Islamic philosophers, who later came to strongly influence the late medieval philosophers of western Christendom, and the Jewish diaspora in the Mediterranean area. While there were earlier Muslim philosophers such as Al Kindi, chronologically the three most influential concerning the intellect were Al Farabi, Avicenna, and finally Averroes, a westerner who lived in Spain and was highly influential in the late Middle Ages amongst Jewish and Christian philosophers.
