“I think one of the things you and I have to learn is that we have to live without the consolation of belonging to a Church....Of one thing I am certain. The religion of the future will have to be extremely ascetic, and by that I don't mean just going without food and drink.”

“If I have exhausted the justifications, I have reached bedrock and my spade is turned. Then I am inclined to say: 'This is simply what I do.”

“If you and I are to live religious lives, it mustn't be that we talk a lot about religion, but that our manner of life is different. It is my belief that only if you try to be helpful to other people will you in the end find your way to God.”

“I am not interested in constructing a building, so much as in having a perspicuous view of the foundations of possible buildings.”

“There are two godheads: the world and my independent I. I am either happy or unhappy, that is all. It can be said: good or evil do not exist. A man who is happy must have no fear. Not even in the face of death. Only a man who lives not in time but in the present is happy.”

“If we take eternity to mean not infinite temporal duration but timelessness, then eternal life belongs to those who live in the present.”

“Just be indipendent of the external world, so you don't have to fear for what's in it.”
