Presenting a series of powerful arguments, Robert Garner proposes that animal rights must be considered within the discourse on justice. The book offers an ideal theory of animal rights as well as a more achievable nonideal theory which we must use to get to the ideal, rejecting an array of alternative positions. The work contains much that is of value to animal ethicists, such as a novel consideration of the argument from marginal cases, and much that will be convincing for (...) those political thinkers and ethicists not already convinced of the moral significance of nonhuman animals. The text occasionally falls into an unfortunate "us and them" dynamic, and practical considerations are, in places, underdeveloped. These shortcomings do not detract from the value of the work, and the book comes highly recommended: It is readable, rigorous and, most importantly, highly convincing. (shrink)
