The following passage, however, must have slipped past the sensibility monitors. A little context: Midgley is making the point that common experience shows us that sympathy and understanding generally extend beyond the species barrier--we have relationships with pets and other animals, and attribute various states to them--such as pain and interests--without much ado (until behaviorists come along and trip us up with theory). Even people who use animals as beasts of burden and treat them more or less as property generally do not treat them the way they do inanimate tools; indeed, such treatment would not work. Thus, Midgley writes:
[W]e should notice a similar arbitrariness often appearing in the treatment of human dependants, so that we can scarcely argue that there is no real capacity for sympathy towards animals. In the treatment of other people, of course, our natural caprice is constantly disciplined by the deliberate interference of morality. We know that we must not eat our grandmothers or our children merely because they annoy us. Over animals this restraint is usually much less active; caprice has much freer play. (p. 114)Of course, I think it would be silly to read Midgley as suggesting that we eat animals because they annoy us. But what a strange example and transition! In fact, I would suggest that I know no such thing as what she suggests. What I "know" is that grandmothers and children are not to be eaten. Perhaps then, by addition, I know that grandmothers and children are not to be eaten merely on the grounds that they annoy us. But if it is not ok to eat grandmothers and children merely because they annoy us, perhaps there are stronger reasons that would justify eating grandmothers and children? (Have you seen The Road yet, or read it?) At any rate, I have trouble understanding what the relationship is between being annoyed by something and thinking that I can or ought to eat it...
