Abstract

I argue that the equal rights views of Tom Regan and Evelyn B. Pluhar must be rejected because they have unacceptable consequences. My objection is similar to one made in the literature by Mary Anne Warren, but I develop it in more detail and defend it from several plausible responses that an equal rights theorist might make. I formulate a theory, a moderate form of perfectionism, that makes a valuedistinction between moral agents and moral patients according to which although both have rights, these rights are not equal. This theory avoids the unacceptable consequences of the equal rights view and is immune to the marginal cases arguments that typical full-personhood theories succumb to. This moderate perfectionism generates an obligation for people to be vegetarians (in most cases) and to severely curtail animal experimentation.
