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.
Muhammad IqbalDivine life is in touch with the whole universe on the analogy of the soul's contact with the body.
Muhammad IqbalA wrong concept misleads the understanding; a wrong deed degrades the whole man, and may eventually demolish the structure of the human ego.
