“A most important book that will change the way many of us look at animals—and, ultimately, at ourselves.” - Chicago Tribune
“Singer’s documentation is unrhetorical and unemotional, his arguments tight and formidable, for he bases his case on neither personal nor religious nor highly abstract philosophical principles, but on moral positions most of us already accept.” - New York Times Book Review
"This book is a must . . . not just for every animal lover but forevery civilized reader." - Cleveland Amory
“This book can’t help but make you think twice about whether or not animals have rights. It is so lucid and smart and thoroughly researched, without a hint of hysteria. I couldn’t put it down.” - Rick Moody, author of The Ice Storm
"In its first incarnation, Animal Liberation became the indispensable foundational text for the movement whose name it bore. In its new, updated, and wholly rewritten form, Animal Liberation Now provides not only a survey – sober, authoritative, and chilling – of what goes on today in the factory farms and research laboratories of the world, but also a guide, written with the honesty and philosophical depth characteristic of all of Peter Singer’s work, through the complexities of the modern debate on animal rights." - J.M. Coetzee, author of The Lives of Animals and Disgrace
“I became a vegetarian when I read Animal Liberation back in the 1970s. Then and there I stopped eating meat. If I’d read this revised Animal Liberation Now I’d have become a vegan much sooner.”  - Jane Goodall
“Peter Singer may be the most moral person on the planet. If his ruthlessly consistent altruism makes the rest of us shuffle our feet in discomfort, or even noisily disrupt his lectures, that’s all the more reason to read this book.”  - Richard Dawkins, Fellow of the Royal Society, author of The Selfish Gene, The God Delusion, and The Ancestor’s Tale
“Animal Liberation Now is a truly revolutionary text to read, treasure and pass along. Peter Singer’s Animal Liberation was a philosophical bombshell when it first appeared in 1975. It forever changed the conversation about our treatment of animals, and this new book will both enrich and sharpen that conversation.” - Ingrid Newkirk, founder and president, People for the Ethical Treatment of Animals
“Whether you are new to these ideas, or Animal Liberation has already changed your life, Animal Liberation Now is essential in helping us all see our place in today's world and the urgency of ending the exploitation of animals.” - Leah Garcès, CEO, Mercy For Animals
“Singer's great achievement in Animal Liberation was to bring activism together with a powerful philosophical theory founded on the principle of equal consideration of interests.  Animal Liberation Now shows that the book that changed the world a half century ago is even more relevant today.” - Dale Jamieson, Director, Center for Environmental and Animal Protection, New York University
“The first edition of Animal Liberation helped me make a career-changing decision to establish a more egalitarian biology. Singer's updated edition is even more valuable because given what we've learned about animal minds in recent years, it is painfully clear that animals are not disposable, simple-minded, unfeeling objects. We should have got rid of that human-centric arrogance decades ago.” - Marc Bekoff, professor emeritus of Ecology and Evolutionary Biology, University of Colorado, Boulder, and author of The Emotional Lives of Animals, and The Animals' Agenda
