Waal shows how ethical behavior is as much a matter of evolution as any other trait.

The moral case for experimentation on animals rests both on the goods to be realized, the evils to be avoided thereby, and on the duty to respect persons and to secure them in the enjoyment of their natural moral rights. Some experimentation on animals presents no problems of justification as it involves no harm at all to the animals which are the subject of experiments and is such as to seek to achieve an advance in knowledge. Experiments on non-sentient animals, (...) like those on plant life, may harm the subjects but in ways that in themselves need raise no morally significant issues. Moral issues may arise if the subjects of experiments are members of an endangered species and for like reasons but not simply on account of the harm caused by the experiment to the subjects. Other experimentation on animals is to be justified solely in terms of its benefit to animals, even though it involves harm to the animals upon which experiments are performed. There are many poisons and diseases to which animals and not human beings are exposed which give rise to the need for experiments to determine effective therapies, treatments, or other remedies. Examples include annual rye grass toxicity, foot-and-mouth disease, the many fowl diseases, and so on. Human beings commonly have an interest in successfully experimenting to find effective remedies, either a financial interest as with farm animals, race horses and the like, amusement interest as with pets, or a concern not to have a species or variety become extinct. The moral case for such experiments may be strengthened by reference to such interests if they in turn have a moral basis, but generally it does not depend for its validity on this. Other experimentation that harms the animals involved is to be justified in terms of the benefits to be realized and evils lessened for persons by the knowledge and the use of the knowledge gained, where the knowledge is used to secure the enjoyment of their moral rights by persons. Much experimentation benefits both persons, contributing to the securing of their enjoyment of their moral rights, and animals which do not possess moral rights, and is to be morally justified on both counts. Obviously a great amount of experimentation occurs today which does not admit of justification along any of these lines, and hence, is such that it must be condemned as being morally wrong. (shrink)

David DeGrazia’s stated purposes for Taking Animals Seriously are to apply a coherentist methodology to animal ethics, to do the philosophical work necessary for discussing animal minds, and to fill in some of the gaps in the existing literature on animal ethics.

: Many environmentalists criticize as unecological the emphasis that animal liberationists and animal rights theorists place on preventing animal suffering. The strong form of their objection holds that both theories ab-surdly entail a duty to intervene in wild predation. The weak form holds that animal welfarists must at least regard predation as bad, and that this stance reflects an arrogance toward nature that true environmentalists should reject. This paper disputes both versions of the predation critique. Animal welfarists are not committed (...) to protecting the rabbit from the fox, nor do their principles implicitly deprecate nature.

From Bishop Wilberforce in the 1860s to the advocates of "creation science" today, defenders of traditional mores have condemned Darwin's theory of evolution as a threat to society's values. Darwin's defenders, like Stephen Jay Gould, have usually replied that there is no conflict between science and religion--that values and biological facts occupy separate realms. But as James Rachels points out in this thought-provoking study, Darwin himself would disagree with Gould. Darwin, who had once planned on being a clergyman, was convinced (...) that natural selection overthrew our age-old religious beliefs. Created from Animals offers a provocative look at how Darwinian evolution undermines many tenets of traditional philosophy and religion. James Rachels begins by examining Darwin's own life and work, presenting an astonishingly vivid and compressed biography. We see Darwin's studies of the psychological links in evolution (such as emotions in dogs, and the "mental powers" of worms), and how he addressed the moral implications of his work, especially in his concern for the welfare of animals. Rachels goes on to present a lively and accessible survey of the controversies that followed in Darwin's wake, ranging from Herbert Spencer's Social Darwinism to Edward O. Wilson's sociobiology, and discusses how the work of such influential intellects as Descartes, Hume, Kant, T.H. Huxley, Henri Bergson, B.F. Skinner, and Stephen Jay Gould has contributed to--or been overthrown by--evolutionary science. Western philosophy and religion, Rachels argues, have been shaken by the implications of Darwin's work, most notably the controversial idea that humans are simply a more complex kind of animal. Rachels assesses a number of studies that suggest how closely humans are linked to other primates in behavior, and then goes on to show how this idea undercuts the work of many prominent philosophers. Kant's famous argument that suicide reduces one to the level of an animal, for instance, is meaningless if humans are, in fact, animals. Indeed, humanity's membership in the animal kingdom calls into question the classic notions of human dignity and the sacredness of human life. What we need now, Rachels contends, is a philosophy that does not discriminate between different species, one that addresses each being on an individual basis. With this sweeping survey of the arguments, the philosophers, and the deep implications surrounding Darwinism, Rachels lays the foundations for a new view of morality. Vibrantly written and provocatively argued, Created from Animals offers a new perspective on issues ranging from suicide to euthanasia to animal rights. (shrink)

In _Beyond Prejudice_, Evelyn B. Pluhar defends the view that any sentient conative being—one capable of caring about what happens to him or herself—is morally significant, a view that supports the moral status and rights of many nonhuman animals. Confronting traditional and contemporary philosophical arguments, she offers in clear and accessible fashion a thorough examination of theories of moral significance while decisively demonstrating the flaws in the arguments of those who would avoid attributing moral rights to nonhumans. Exposing the traditional (...) view—which restricts the moral realm to autonomous, fully fledged "persons"—as having horrific implications for the treatment of many humans, Pluhar goes on to argue positively that sentient individuals of any species are no less morally significant than the most automomous human. Her position provides the ultimate justification that is missing from previous defenses of the moral status of nonhuman animals. In the process of advancing her position, Pluhar discusses the implications of determining moral significance for children and "abnormal" humans as well as its relevance to population policies, the raising of animals for food or product testing, decisions on hunting and euthanasia, and the treatment of companion animals. In addition, the author scrutinizes recent assertions by environmental ethicists that all living things or that natural objects and ecosystems be considered highly morally significant. This powerful book of moral theory challenges all defenders of the moral status quo—which decrees that animals decidedly do not count—to reevaluate their convictions. (shrink)

The Western world is currently gripped by an obsessive concern for the rights of animals - their uses and abuses. In this book, Leahy argues that this is a movement based upon a series of fundamental misconceptions about the basic nature of animals. This is a radical philosophical questioning of prevailing views on animal rights, which credit animals with a self-consciousness like ours. Leahy's conclusions have implications for issues such as bloodsports, meat eating and fur trading.

Transcending the overplayed debate between utilitarians and rights theorists, the book offers a fresh methodological approach with specific constructive conclusions about our treatment of animals. David DeGrazia provides the most thorough discussion yet of whether equal consideration should be extended to animals' interests, and examines the issues of animal minds and animal well-being with an unparalleled combination of philosophical rigor and empirical documentation. This book is an important contribution to the field of animal ethics.
