"The task of thought in our time is to replace the lost religious and metaphysical foundation of morals by a secular and naturalistic foundation."

“It has been said that man lives by truth, and that the truth will make us free. Nearly the opposite seems to me to be the case. Mankind has managed to live only by means of lies, and the truth may very well destroy us.”

“If God does not lie at the end of any telescope, neither does he lie at the end of any syllogism. I can never starting from the natural order prove the divine order. The proof of the divine order must lie, somehow, within itself. It must be its own witness. For it, like the natural order, is complete within itself, self-contained.”

“Thus we see that mysticism naturally, though not necessarily, becomes intimately associated with whatever is the religion of the culture in which it appears.”

“Thus to say that God is ineffable is to say that no concepts apply to Him, and that He is without qualities.”

“To be genuinely civilized means to be able to walk straightly and to live honorably without the props and crutches of one or another of the childish dreams which have so far supported men. That such a life is likely to be ecstatically happy I will not claim. But that it can be lived in quiet content, accepting resignedly what cannot be helped not expecting the impossible, and being thankful for small mercies, this I would maintain. That it will be difficult for men in general to learn this lesson I do not deny. But that it will be impossible I would not admit since so many have learned it already.”

“All religious thought and speech are through and through symbolic. And this fundamental insight is perhaps as old as religion itself.”
