Sentience, Rationality, and Moral Status: A Further Reply to Hsiao

Timothy Hsiao argues that animals lack moral status because they lack the sort of higher-level rationality required for membership in the moral community. Stijn Bruers and Laszl ErdAs have already raised a number of objections to this argument, to which Hsiao has replied with some success. But I think a stronger critique can be made. Here I raise further objections to three aspects of Hsiao's view: his conception of the moral community, his idea of root capacities grounded in one's nature, and his explanation of why cruelty is wrong. I also argue that sentience is a more plausible candidate for the morally salient capacity than rationality.
