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.

One who gains strength by overcoming obstacles possesses the only strength which can overcome adversity.

Your soul suffers if you live superficially.

The deeper we look into nature, the more we recognize that it is full of life, and the more profoundly we know that all life is a secret and that we are united with all life that is in nature.

We ought all to make an effort to act on our first thoughts and let our unspoken gratitude find expression. Then there will be more sunshine in the world, and more power to work for what is good.

To the man who is truly ethical all life is sacred, including that which from the human point of view seems lower in the scale. He makes distinctions only as each case comes before him, and under the pressure of necessity, as, for example, when it falls to him to decide which of two lives he must sacrifice in order to preserve the other. But all through this series of decisions he is conscious of acting on subjective grounds and arbitrarily, and knows that he bears the responsibility for the life which is sacrificed.

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