Universal Kinship

The Universal Kinship is a 1906 book by American zoologist, philosopher, educator and socialist J. Howard Moore. In the book, Moore advocated for a secular sentiocentric philosophy, called the &quote;Universal Kinship&quote;, which mandated the ethical consideration and treatment of all sentient beings based on Darwinian principles of shared evolutionary kinship, and a universal application of the Golden Rule; a direct challenge to anthropocentric hierarchies and ethics. The book was endorsed by Henry S. Salt, Mark Twain and Jack London.
