ABSTRACT
James Rachels identifies Peter Singer’s argument that it is wrong to cause pain unless there is a good enough reason as the argument which convinced him to become a vegetarian. Rachels describes some of the facts involved in the meat-production industry and maintains that such facts are a vital part of the argument. Since the facts are well established, how can we account for so many people being unmoved by these facts? According to Rachels, there is a difference between how scientists and animal-rights advocates think about the cognitive abilities of nonhumans. But for Rachels the important issue is animal pain.
