When Richard Ryder coined the term ‘speciesism’ over two decades ago, the issue of animal rights was very much a minority concern that had associations with crankiness. Today, the animal rights movement is well-established across the globe and continues to gain momentum, with animal experimentation for medical research high on the agenda and very much in the news. This pioneering book - an historical survey of the relationship between humans and non-humans - paved the way for these developments. Revised, updated to include the movement’s recent history and available in paperback for the first time, and now introducing Ryder’s concept of ‘painism’, Animal Revolution is essential reading for anyone who cares about animals or humanity. Dr Richard D. Ryder is a psychologist, ethicist, historian and political campaigner. He is also a past chairman of the RSPCA. His other books include Victims of Science: The Use of Animals in Research, The Political Animal: The Conquest of Speciesism and Animal Welfare and the Environment (editor). As Mellon Professor, he taught Animal Welfare at Tulane University.
