With anecdotes and a dose of humour, Rollin pokes holes in the neutral, objective, and value-free stance of animal-using scientists in the positivist tradition. He shows how this stance leads to the denial of the existence of animal consciousness and pain, and he points out the consequences. His work will help professionals and amateurs with an interest in the moral status of animals in their attempts to penetrate the fortress of scientific ideology and practice, and to effect change.
