I have always held firmly to the thought that each one of us can do a little to bring some portion of misery to an end.

The tragedy of life is what dies inside a man while he lives.

Grow into your ideals so that life cannot rob you of them.

Renunciation of thinking is a declaration of spiritual bankruptcy.

Because I have confidence in the power of truth and in the spirit, I believe in the future of mankind. Affirmation of the world and of life contains within itself an optimistic willing and hoping which can never be lost. It is, therefore, never afraid to face the dismal reality and to see it as it really is.

We should all be thankful for those people who rekindle the inner spirit.

We cannot understand what happens in the universe. What is glorious in it is united with what is full of horror. What is full of meaning is united to what is senseless. The spirit of the universe is at once creative and destructive — it creates while it destroys and destroys while it creates, and therefore it remains to us a riddle. And we must inevitably resign ourselves to this.
