More than twenty years after its original publication, _The Case for Animal Rights _is an acknowledged classic of moral philosophy, and its author is recognized as the intellectual leader of the animal rights movement. In a new and fully considered preface, Regan responds to his critics and defends the book's revolutionary position.

The most popular and convincing arguments for the claim that vegetarianism is morally obligatory focus on the extensive, unnecessary harm done to animals and to the environment by raising animals industrially in confinement conditions (factory farming). I outline the strongest versions of these arguments. I grant that it follows from their central premises that purchasing and consuming factoryfarmed meat is immoral. The arguments fail, however, to establish that strict vegetarianism is obligatory because they falsely assume that eating vegetables is the (...) only alternative to eating factory-farmed meat that avoids the harms of factory farming. I show that these arguments not only fail to establish that strict vegetarianism is morally obligatory, but that the very premises of the arguments imply that eating some (non-factory-farmed) meat rather than only vegetables is morally obligatory. Therefore, if the central premises of these usual arguments are true, then strict vegetarianism is immoral. (shrink)

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.

1. Animal Cruelty Industrial farming is appallingly abusive to animals. Pigs. In America, nine-tenths of pregnant sows live in “gestation crates. ” These pens are so small that the animals can barely move. When the sows are first crated, they may flail around, in an attempt to get out. But soon they give up. Crated pigs often show signs of depression: they engage meaningless, repetitive behavior, like chewing the air or biting the bars of the stall. The sows live like (...) this for four months. Gestation crates will be phased out in Europe by the end of 2012, but they will still be used in America.1 In nature, pigs nurse their young for about thirteen weeks. But in industrial farms, piglets are taken from their mothers after about ten days. Because the piglets are weaned prematurely, they develop a lifelong craving to suck and chew. But the farmers don’t want them sucking and chewing on other pigs’ tails. So the growers routinely snip off the tails of all their pigs. They do this with a pair of pliers and no anesthetic. However, the whole tail is not removed; a tender stump remains. The point is to render the area sensitive, so the pigs being chewed on will fight back. Which they do.2 Over 113 million pigs are slaughtered each year in America.3 Typically, these pigs are castrated, their needle teeth are clipped, and one of their ears is notched for identification —all without pain relief.4 In nature, pigs spend up to three quarters of their waking hours foraging and exploring their environment.5 But in the factory farms, “tens of thousands of hogs spend their entire lives ignorant of earth or straw or sunshine, crowded together beneath a metal roof standing on metal slats suspended over a septic tank. ”6 Bored, and in constant pain, the pigs must perpetually inhale the fumes of their own waste. These pigs often get sick, and their ill health is exacerbated by the overcrowding. In 2000, the U.S. Department of Agriculture compared hog farms containing over 10,000 pigs—which is the norm—with farms containing under 2,000 pigs. (shrink)

Though the vegetarian movement sparked by Peter Singer’s book Animal Liberation has achieved some success, there is more animal suffering caused today due to factory farming than there was when the book was originally written. In this paper, I argue that there may be a technological solution to the problem of animal suffering in intensive factory farming operations. In particular, I suggest that recent research indicates that we may be very close to, if not already at, the point where we (...) can genetically engineer factory-farmed livestock with a reduced or completely eliminated capacity to suffer. In as much as animal suffering is the principal concern that motivates the animal welfare movement, this development should be of central interest to its adherents. Moreover, I will argue that all people concerned with animal welfare should agree that we ought to replace the animals currently used in factory farming with animals whose ability to suffer is diminished if we are able to do so.

It is one thing to say that the suffering of non-human animals ought to be considered equally with the like suffering of humans; quite another to decide how the wrongness of killing non-human animals compares with the wrongness of killing human beings. It is argued that while species makes no difference to the wrongness of killing, the possession of certain capacities, in particular the capacity to see oneself as a distinct entity with a future, does. It is claimed, however, that (...) this is not the only factor to be taken into account: pleasant or happy life is in itself good. The application of these conclusions to killing animals for food is then considered, with some passing reflections on infanticide. (shrink)

This volume provides a general overview of the basic ethical and philosophical issues of animal rights. It asks questions such as: Do animals have moral rights? If so, what does this mean? What sorts of mental lives do animals have, and how should we understand welfare? By presenting models for understanding animals' moral status and rights, and examining their mental lives and welfare, David DeGrazia explores the implications for how we should treat animals in connection with our diet, zoos, and (...) research. Animal Rights distinguishes itself by combining intellectual rigor with accessibility, offering a distinct moral voice with a non-polemical tone. (shrink)

Based on his theory of animalrights, Regan concludes that humans are morallyobligated to consume a vegetarian or vegandiet. When it was pointed out to him that evena vegan diet results in the loss of manyanimals of the field, he said that while thatmay be true, we are still obligated to consumea vegetarian/vegan diet because in total itwould cause the least harm to animals (LeastHarm Principle, or LHP) as compared to currentagriculture. But is that conclusion valid? Isit possible that some other (...) agriculturalproduction alternatives may result in leastharm to animals? An examination of thisquestion shows that the LHP may actually bebetter served using food production systemsthat include both plant-based agriculture and aforage-ruminant-based agriculture as comparedto a strict plant-based (vegan) system. Perhapswe are morally obligated to consume a dietcontaining both plants and ruminant(particularly cattle) animal products. (shrink)

Faced with the choice between supporting industrial plant agriculture and hunting, Tom Regan’s rights view can be plausibly developed in a way that permits a form of hunting we call “dignitarian.” To motivate this claim, we begin by showing how the empirical literature on animal deaths in plant agriculture suggests that a non-trivial amount of hunting would not add to animal harm. We discuss how Tom Regan’s miniride principle appears to morally permit hunting in that case, and we address recent (...) objections by Jason Hanna to environmentally-based culling that may be seen to speak against this conclusion. We then turn to dignity, which is especially salient in scenarios where harm is necessary or justifiable. We situate “dignitarian” hunting within a larger framework of adversarial ethics, and argue that dignitarian hunting gives animals a more dignified death than the alternatives endemic to large-scale plant agriculture, and so is permissible based on the kinds of principles that Regan endorses. Indeed, dignitarian hunting may actually fit better with Regan’s widely endorsed animal rights framework than the practice of many vegans, and should only be rejected if we’re just as willing to condemn supporting conventional plant agriculture.
