“I am life which wills to live, in the midst of life which wills to live. As in my own will-to-live there is a longing for wider life and pleasure, with dread of annihilation and pain; so is it also in the will-to-live all around me, whether it can express itself before me or remains dumb. The will-to-live is everywhere present, even as in me. If I am a thinking being, I must regard life other than my own with equal reverence, for I shall know that it longs for fullness and development as deeply as I do myself. Therefore, I see that evil is what annihilates, hampers, or hinders life. And this holds true whether I regard it physically or spiritually. Goodness, by the same token, is the saving or helping of life, the enabling of whatever life I can to attain its highest development. “

Albert Schweitzer,  The Philosophy of Civilization
