J. Howard Moore

John Howard Moore was an American zoologist, philosopher, educator, and social reformer. He wrote on animal ethics, ethical vegetarianism, humane education, socialism, temperance, and evolutionary biology. In The Universal Kinship (1906), Moore set out a secular ethic that applied the Golden Rule to all sentient beings and used Darwinian ideas of evolutionary continuity between humans and other animals.
