There are... things which a man is afraid to tell even to himself, and every decent man has a number of such things stored away in his mind.

And man has actually invented God. And what’s strange, what would be marvellous, is not that God should really exist; the marvel is that such an idea, the idea of the necessity of God, could enter the head of such a savage, vicious beast as man.

So long as man remains free he strives for nothing so incessantly and painfully as to find someone to worship

Without some goal and some efforts to reach it, no man can live.

The most pressing question on the problem of faith is whether a man as a civilized being… can believe in the divinity of the Son of God, Jesus Christ, for therein rests the whole of our faith.

The cleverest of all, in my opinion, is the man who calls himself a fool at least once a month.
