The will-to-live becomes the will-to-power.

I know that the Communists are atheistic and godless, but I don't think that that's what's primarily the matter with them. What's primarily the matter with them is that they worship a false god. That's much more dangerous than when people don't believe anything; they may be confused, they may not have a sense of the meaning of life, but they're not dangerous.

Our dreams of a pure virtue are dissolved in a situation in which it is possible to exercise the virtue of responsibility toward a community of nations only by courting the prospective guilt of the atomic bomb.

Nothing we do, however virtuous, can be accomplished alone; therefore we are saved by love.

The society in which each man lives is at once the basis for, and the nemesis of, that fulness of life which each man seeks.

My personal attitude toward atheists is the same attitude that I have toward Christians, and would be governed by a very orthodox text: "By their fruits shall ye know them." I wouldn't judge a man by the presuppositions of his life, but only by the fruits of his life. And the fruits - the relevant fruits - are, I'd say, a sense of charity, a sense of proportion, a sense of justice. And whether the man is an atheist or a Christian, I would judge him by his fruits, and I have therefore many agnostic friends.

Ultimately evil is done not so much by evil people, but by good people who do not know themselves and who do not probe deeply.
