“Genius is religious.”

“The turmoil and dislocations confronting present-day society will not be solved until both the scientific and religious genius of the human race are fully utilized.”

“The truth is that solitude is the creative condition of genius, religious or secular, and the ultimate sterilising of it. No human soul can long ignore "the giant agony of the world" and live, except indeed the mollusc life, a barnacle upon eternity.”

“All the greatest men are maniacs. They are possessed by a mania which drives them forward towards thier goal. The great scientists, the philosophers, the religious leaders - all maniacs. What else but a blind singlenee of purpose could have given focus to thier genius, would have kept them in the groove of purpose. Mania ... is as priceless as genius.”

“The religious geniuses of all ages have been distinguished by this kind of religious feeling, which knows no dogma and no God conceived in man's image; so that there can be no church whose central teachings are based on it. Hence it is precisely among the heretics of every age that we find men who were filled with this highest kind of religious feeling and were in many cases regarded by their contemporaries as atheists, sometimes also as saints. Looked at in this light, men like Democritus, Francis of Assisi, and Spinoza are closely akin to one another.”

“the scientist's religious feeling takes the form of a rapturous amazement at the harmony of natural law, which reveals an intelligence of such superiority that, compared with it, all the systematic thinking and acting of human beings is utterly insignificant reflection. This feeling is the guiding principle of his life and work, in so far as he succeeds in keeping himself from the shackles of selfish desire. It is beyond question closely akin to that which has possessed the religious geniuses of all ages.”
