Allama Iqbal said that

The spirit of philosophy is one of free inquiry. It suspects all authority. Its function is to trace the uncritical assumptions of human thought to their hiding places, and in this pursuit it may finally end in denial or a frank admission of the incapacity of pure reason to reach the ultimate reality.
