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.

Despite its potential for radically reducing the harm inflicted on nonhuman animals in the pursuit of food, there are a number of objections grounded in animal ethics to the development of in vitro meat. In this paper, I defend the possibility against three such concerns. I suggest that worries about reinforcing ideas of flesh as food and worries about the use of nonhuman animals in the production of in vitro meat can be overcome through appropriate safeguards and a fuller understanding of the interests that nonhuman animals actually possess. Worries about the technology reifying speciesist hierarchies of value are more troublesome, however. In response to this final challenge, I suggest that we should be open not just to the production of in vitro nonhuman flesh, but also in vitro human flesh. This leads to a consideration of the ethics of cannibalism. The paper ultimately defends the position that cannibalism simpliciter is not morally problematic, though a great many practices typically associated with it are. The consumption of in vitro human flesh, however, is able to avoid these problematic practices, and so should be considered permissible. I conclude that animal ethicists and vegans should be willing to cautiously embrace the production of in vitro flesh.
