REPLY TO SINGER "[Peter] Singer. . . has written major articles, including one for the Encyclopedia Britannica, [Footnote: "The esteemed Encyclopedia Britannica is not above criticism in its choice of authors..."] and books on ethics and that he has edited numerous books on ethics and philosophy. His works may be widely used, as he claims, in philosophy and/or ethics courses in various countries. Nevertheless, these facts do not exempt him from criticism of what we consider to be unethical behavior. With regard to Singer's philosophical position, many philosophers are not impressed either with Singer's works or by his arguments. In addition to Peter Carruthers' critical analysis,. . . Richard Sorabji. . . states that the arguments of both Singer and Tom Regan for the equality of animals with humans are one-dimensional and as such are not persuasive. . . . . . Other philosophers have also been highly critical of the philosophy of animal rights. For example, Robert Nozick, chairman of the Department of Philosophy at Harvard University, had this to say in a review of Tom Regan's book on the subject: "Animal rights seems a topic for cranks. . . The mark of cranks is disproportionateness. lt is not merely that they devote great energy to their issue . . . They view the issue as far more important than it is, more pressing than others that, in fact, are more significant." Further, on the subject of 'speciesism,' Nozick stated: "Our view of what treatment severely retarded people are owed surely in part depends on their being human, members of the human species. Sweeping away this consideration as morally irrelevant can only result in society's treating severely retarded people like animals, not the other way around." And Charles Griswold, Jr., professor of philosophy at Howard University, wrote in the Washington Post: "The animal rights movement illustrates the incoherent nature of a moral passion become immoral by virtue of its extremism. In the name of the laudable quality of humaneness, the use of animals for food, clothing and medical experimentation is prohibited. Research that could save your child's life, or save you from an excrucitating disease, is declared unethical. The result is inhumanity toward man." [pp.149-150] Sharon M. Russell and Charles S.
