Morality is of the highest importance - but for us, not for God.

You cannot solve current problems with current thinking. Current problems are the result of current thinking.

In living through this great epoch, it is difficult to reconcile oneself to the fact that one belongs to that mad, degenerate species that boasts of its free will.

Intelligence makes clear to us the interrelationship of means and ends. But mere thinking cannot give us a sense of the ultimate and fundamental ends. To make clear these fundamental ends and valuations and to set them fast in the emotional life of the individual, seems to me precisely the most important function which religion has to form in the social life of man.

Mere unbelief in a personal God is no philosophy at all.
