Do animals have moral rights? In contrast to the philosophical gurus of the animal rights movement, whose opinion has held moral sway in recent years, Peter Carruthers here claims that they do not. He explores a variety of moral theories, arguing that animals lack direct moral significance. This provocative but judiciously argued book will appeal to all those interested in animal rights, whatever their initial standpoint. It will also serve as a lively introduction to ethics, demonstrating why theoretical issues in (...) ethics actually matter. (shrink)

Peter Singer famously argued in Animal Liberation that almost all of us are speciesists, unjustifiably favoring the interests of humans over the similar interests of other animals. Although I long found that charge compelling, I now find myself having doubts. This article starts by trying to get clear about the nature of speciesism, and then argues that Singer's attempt to show that speciesism is a mere prejudice is unsuccessful. I also argue that most of us are not actually speciesists at (...) all, but rather accept a view I call modal personism. Although I am not confident that modal personism can be adequately defended, it is, at the very least, a philosophical view worthy of further consideration. (shrink)

Many think doing animal ethics demands we see moral humanism as a speciesist prejudice of the kind found with sexism and racism. The only serious case for this rests on the Argument from Marginal Cases. We find that argument to the point, but show that properly understood it supports humanism. Understanding why it does this lets us see how we ought to go on in animal ethics.

Entomophagy—eating insects—is getting a lot of attention these days. However, strict vegans are often uncomfortable with entomophagy based on some version of the precautionary principle: if you aren’t sure that a being isn’t sentient, then you should treat it as though it is. But not only do precautionary principle-based arguments against entomophagy fail, they seem to support the opposite conclusion: strict vegans ought to eat bugs.

Why does a baby who is otherwise cognitively similar to an animal such as a dog nevertheless have a higher moral status? We explain the difference in moral status as follows: the baby can, while a dog cannot, participate as a rearee in what we call “person-rearing relationships,” which can transform metaphysically and evaluatively the baby’s activities. The capacity to engage in these transformed activities has the same type of value as the very capacities (i.e., intellectual or emotional sophistication) that (...) explain unimpaired adult humans’ high moral status. We attempt to extend this account to individuals with severe cognitive impairments. (shrink)

This paper argues that navigating insects and spiders possess a degree of mindedness that makes them appropriate (in the sense of “possible”) objects of sympathy and moral concern. For the evidence suggests that many invertebrates possess a belief-desire-planning psychology that is in basic respects similar to our own. The challenge for ethical theory is find some principled way of demonstrating that individual insects do not make moral claims on us, given the widely held belief that some other “higher” animals do (...) make such claims on us.
