In this work, J. Howard Moore advocates for the recognition of a kinship between humans and nonhuman animals, and a universal application of the Golden Rule as an ethical framework towards the treatment of all sentient beings. The evidence for this kinship is detailed in three sections: the physical, the psychical and the ethical.
John Howard Moore was an American zoologist, philosopher, educator and socialist. He authored several articles, books, essays and pamphlets on ethics, vegetarianism, humanitarianism and education.
