Animal Liberation by Peter Singer
Review. "Despite the title which may shy people away with the threat of extremism, Singer takes a path uncharted by modern philosophers and compassionate thinkers. He decides not to tug on the heart strings and presents a mind opening appeal to question our moral boundaries."
Animal Rights Book Review by David Kopel
Book Review. "Want to upset all the pre-conceptions of your life, and look at the world around you in a radically new way? Then read Peter Singer's book Animal Rights. Written by an Australian philosophy professor in the 1970s, this book is the founding book of the modern AR movement. As such, it may be one of the most influential books of the 20th century."
