J. Howard (John Howard) Moore

John Howard Moore was an American zoologist, philosopher, educator, and social reformer. He was best known for his advocacy of ethical vegetarianism and his pioneering role in the animal rights movement, both deeply influenced by his ethical interpretation of Darwin's theory of evolution. Moore's most influential work, The Universal Kinship (1906), introduced a sentiocentric philosophy he called the doctrine of Universal Kinship, arguing that the ethical treatment of animals, rooted in the Golden Rule, is essential for human ethical evolution, urging humans to extend their moral considerations to all sentient beings, based on their shared physical and mental evolutionary kinship.
