I am a vegetarian because I believe that present-day ethics is founded on that puerile, pre-Darwinian delusion that all other kinds of creatures and … - J. Howard Moore

John Howard Moore wrote and worked with feverish haste, and he believed that the blind and heartless world would listen to his words and mend its ways. But humanity went on trading and dickering, lying and cheating, marrying and dying, and never heard his voice. One day he opened his eyes and knew his work was in vain, and feeling the weight of the universal sorrow on his soul, he took his life. The coroner's jury determined that "he died from his own hand, while suffering under a temporary fit of insanity." I tell you he died from his own hand while suffering under a temporary fit of sanity [...] Poor, dead dreamer! You are not the first or last mortal to learn the truth. Other men have awakened from the mad and blissful dream of saving mankind from itself. I, too, have dreamed my dreams, had my illusions, and wakened from my sleep [...] Among all who are gathered here there is but one whom we can felicitate on this event, and that one is our friend who lies peaceful and all unconscious of the world. If any word of mine could call back his troubled soul, I should feel myself guiltier far than I would to cause a brother's death.

It has been called a problem of adaptation. There is a subjective and there is an objective, a self and a not-self. And between this self and the not-self there is incessant irrelation. That which is not-self is a process, always changing. It never tires of adopting new attitudes toward the self. The self also is a process, and hence is continually losing joint, or is in continual danger of losing joint, with its environment. Life, therefore, at best, since in the nature of things it is a struggle and a search, is an enterprise with exasperating lack of sunshine.

A central truth of the Darwinian philosophy is the unity and consanguinity of all organic life. And during the next century or two the ethical corollary of this truth is going to receive unprecedented recognition in all departments of human thought.
