Within both Eastern and Western philosophical traditions, there exist schools of thought which, while not exclusively rationalist, utilize reason and logic in the context of intuitively realized metaphysical truth. Throughout its development, Islamic philosophy was influenced by many of these philosophical schools. Comparative study of these different traditions together with historical study can reveal their influence more completely than would be possible by using the historical approach alone. It can also benefit practicing Muslims by introducting them to philosophical perspectives outside of modern, humanistic modes of thought which seem to dominate current discussion. Furthermore, comparative philosophy will enrich Western understanding of Islamic doctrine.
