Pain is a more terrible lord of mankind than even death itself.

Any profound view of the world is mysticism. It has, of course, to deal with life and the world, both of which are nonrational entities.

The city of truth cannot be built on the swampy ground of skepticism.

Joy, sorrow, tears, lamentation, laughter -- to all these music gives voice, but in such a way that we are transported from the world of unrest to a world of peace, and see reality in a new way, as if we were sitting by a mountain lake and contemplating hills and woods and clouds in the tranquil and fathomless water.

The quiet conscience is an invention of the devil.

We cannot abdicate our conscience to an organization, nor to a government. 'Am I my brother's keeper?' Most certainly I am! I cannot escape my responsibility by saying the State will do all that is necessary. It is a tragedy that nowadays so many think and feel otherwise.

Ethics, too, are nothing but reverence for life. This is what gives me the fundamental principle of morality, namely, that good consists in maintaining, promoting, and enhancing life, and that destroying, injuring, and limiting life are evil.
