David DeGrazia

When a Benjamin Franklin or a Jeremy Bentham suggested that we look at animals in a radically different way, the suggestion was probably greeted not with a refutation but with a laugh or sneer. Until animals are taken seriously enough that this possibility is clearly in mind, intelligent discussion of the reasons for and against equal consideration is impossible.
