“A conviction akin to religious feeling of the rationality or intelligibility of the world lies behind all scientific work of a high order.”

“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.”

“I assert that the cosmic religious experience is the strongest and the noblest driving force behind scientific research.”

“Which is the more useful, the scientific world-view, with all its wonderful technical miracles, or the religious world-view, with its sense of purpose and belonging?”

“I maintain that the cosmic religious feeling is the strongest and noblest motive for scientific research.”

“The science of a religious man must be scientific; the religion of a scientific man must be religious.”
