Abstract: Most of us believe that we are entitled to treat members of other species in ways which would be considered wrong if inflicted on members of our own species. We kill them for food, keep them confined, use them in painful experiments. The moral philosopher has to ask what relevant difference justifies this difference in treatment. A look at this question will lead us to re-examine the distinctions which we have assumed make a moral difference.
Comment: This journal article is a response to Peter Singer's Animal Liberation, though you need not have read Animal Liberation in order to understand this article, as Steinbock provides a clear overview of Singer's main claims. The text would be useful for rebutting Singer's arguments in a course on animal ethics or environmental ethics. It would also be of use in a course on moral theory that involved questions of moral consideration or moral equality.
