There is no higher religion than human service.

Compassion, in which all ethics must take root, can only attain its full breadth and depth if it embraces all living creatures and does not limit itself to mankind.

Don't stop to ask whether the animal or plant you meet deserves your sympathy, or how much it feels, or even whether it can feel at all: respect it and consider all life sacred.

To affirm life is to deepen, to make more inward, and to exalt the will-to-life. At the same time the man who has become a thinking being feels a compulsion to give every will-to-live the same reverence for life that he gives to his own. He experiences that other life as his own. He accepts as being good: to preserve life, to raise to its highest value life which is capable of development; and as being evil: to destroy life, to injure life, to repress life which is capable of development. This is the absolute, fundamental principle of the moral, and it is a necessity of thought.

Rational thinking which is free from assumptions ends therefore in mysticism. To relate oneself in the spirit of reverence for life to the multiform manifestations of the will-to-live which together constitute the world is ethical mysticism. All profound world-view is mysticism, the essence of which is just this: that out of my unsophisticated and naïve existence in the world there comes, as a result of thought about self and the world, spiritual self-devotion to the mysterious infinite Will which is continuously manifested in the universe.

Who can describe the injustice and the cruelties that in the course of centuries the peoples of color of the world have suffered at the hands of Europeans?... We and our civilization are burdened, really, with a great debt. We are not free to confer benefits on these men, or not, as we please; it is our duty. Anything we give them is not benevolence but atonement.

Train yourself never to put off the word or action for the expression of gratitude.
