Writing in 1895, J. Howard Moore described vegetarianism as the ethical conclusion of the evolutionary kinship of all creatures, calling it the "expansion of ethics to suit the biological revelations of Charles Darwin". He went on to argue that ethics still relied on a "pre-Darwinian delusion" that all nonhuman animals and the world were created specifically for humans. In his 1899 book "Better World Philosophy", Moore contended that human ethics is in an "anthropocentric stage of evolution", having developed "from individual to tribe, and from tribe to race, and from race to sex, and from sex to species, until to-day the ethical conception of many minds includes, with greater or less vividness and sincerity, all sexes, colors, and conditions of "men"." He argued that the next stage of ethical evolution was "zoocentricism", the ethical consideration of the "entire sentient universe".
