This innovative book is the first to couch the debate about animals in the language of justice, and the first to develop both ideal and nonideal theories of justice for animals. It rejects the abolitionist animal rights position in favor of a revised version of animal rights centering on sentience. In this highly anticipated book, Robert Garner presents a clear and persuasive new theory of justice for animals. Because the theory aims to be feasible, and attuned to what can be achieved given the realities of our societies, the book is required reading for all those interested in the future of animal protection.
