"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 whether the man is an atheist or a Christian, I would judge him by his fruits, and I have therefore many agnostic friends."

“Man does not know himself truly except as he knows himself confronted by God. Only in that confrontation does he become aware of his full stature and freedom and of the evil in him.”

The recalcitrant forces in the historical drama have a power and persistence beyond our reckoning.”

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