Reverence for Life affords me my fundamental principle of morality, namely, that good consists in maintaining, assisting, and enhancing life and that to destroy, harm, or to hinder life is evil. Affirmation of the world - that is affirmation of the will to live, which appears in phenomenal forms all around me - is only possible for me in that I give myself out for other life.

The disastrous feature of our civilization is that it is far more developed materially than spiritually. Its balance is disturbed.

It's supposed to be a secret, but I'll tell you anyway. We doctors do nothing. We only help. And encourage the doctor within.

It doesn't matter if an animal can reason. It matters only that it is capable of suffering and that is why I consider it my neighbor.

Ethics is the activity of man directed to secure the inner perfection of his own personality.

In the hearts of people today there is a deep longing for peace. When the true spirit of peace is thoroughly dominant, it becomes an inner experience with unlimited possibilities. Only when this really happens - when the spirit of peace awakens and takes possession of men's hearts, can humanity be saved from perishing.

To the truly ethical man, all of life is sacred, including forms of life that from the human point of view may seem lower than ours.
