A “brilliant” (Chicago Review of Books), “elegantly written, and compelling” (National Review) new theory and call to action on animal rights, ethics, and law from the renowned philosopher Martha C. Nussbaum.Animals are in trouble all over the world. Whether through the cruelties of the factory meat industry, poaching and game hunting, habitat destruction, or neglect of the companion animals that people purport to love, animals suffer injustice and horrors at our hands every day. The world needs an ethical awakening, a consciousness-raising movement of international proportions. In Justice for Animals, one of the world’s most renowned philosophers and humanists, Martha C. Nussbaum, provides “the most important book on animal ethics written to date” (Thomas I. White, author of In Defense of Dolphins). From dolphins to crows, elephants to octopuses, Nussbaum examines the entire animal kingdom, showcasing the lives of animals with wonder, awe, and compassion to understand how we can create a world in which human beings are truly friends of animals, not exploiters or users. All animals should have a shot at flourishing in their own way. Humans have a collective duty to face and solve animal harm. An urgent call to action and a manual for change, Nussbaum’s groundbreaking theory directs politics and law to help us meet our ethical responsibilities as no book has done before.
