Winner of the 1975 National Book Award, this brilliant and widely acclaimed book is a powerful philosophical challenge to the most widely held political and social positions of our age--liberal, socialist, and conservative.

Previous edition, 1st, published in 1971.

Since it appeared in 1971, John Rawls's A Theory of Justice has become a classic. The author has now revised the original edition to clear up a number of difficulties he and others have found in the original book. Rawls aims to express an essential part of the common core of the democratic tradition--justice as fairness--and to provide an alternative to utilitarianism, which had dominated the Anglo-Saxon tradition of political thought since the nineteenth century. Rawls substitutes the ideal of the (...) social contract as a more satisfactory account of the basic rights and liberties of citizens as free and equal persons. "Each person," writes Rawls, "possesses an inviolability founded on justice that even the welfare of society as a whole cannot override." Advancing the ideas of Rousseau, Kant, Emerson, and Lincoln, Rawls's theory is as powerful today as it was when first published. (shrink)

Since its original publication in 1975, this groundbreaking work has awakened millions of concerned men and women to the shocking abuse of animals everywhere--inspiring a worldwide movement to eliminate much of the cruel and unnecessary laboratory animal experimentation of years past. In this newly revised and expanded edition, author Peter Singer exposes the chilling realities of today's "factory farms" and product-testing procedures--offering sound, humane solutions to what has become a profound environmental and social as well as moral issue. An important (...) and persuasive appeal to conscience, fairness, decency and justice, Animal Liberation is essential reading for the supporter and the skeptic alike.--From publisher description.

For thirty years, Peter Singer's Practical Ethics has been the classic introduction to applied ethics. For this third edition, the author has revised and updated all the chapters and added a new chapter addressing climate change, one of the most important ethical challenges of our generation. Some of the questions discussed in this book concern our daily lives. Is it ethical to buy luxuries when others do not have enough to eat? Should we buy meat from intensively reared animals? Am (...) I doing something wrong if my carbon footprint is above the global average? Other questions confront us as concerned citizens: equality and discrimination on the grounds of race or sex; abortion, the use of embryos for research and euthanasia; political violence and terrorism; and the preservation of our planet's environment. This book's lucid style and provocative arguments make it an ideal text for university courses and for anyone willing to think about how she or he ought to live. (shrink)

Book reviewed in this article: Principles of Biomedical Ethics. By Tom L. Beauchamp and James F. Childress.

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.

For many people "animal rights" suggests campaigns against factory farms, vivisection or other aspects of our woeful treatment of animals. Zoopolis moves beyond this familiar terrain, focusing not on what we must stop doing to animals, but on how we can establish positive and just relationships with different types of animals.

This article discusses what is involved in having full moral status, as opposed to a lesser degree of moral status and surveys different views of the grounds of moral status as well as the arguments for attributing a particular degree of moral status on the basis of those grounds.

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)

There is now widespread agreement that many non-human animals are sentient, and that this fact has important moral and political implications. This book is devoted to sketching what this 'sentientist politics' might look like.

A prominent and respected philosopher of animal rights law and ethical theory, Gary L. Francione is known for his criticism of animal welfare laws and regulations, his abolitionist theory of animal rights, and his promotion of veganism and nonviolence as the baseline principles of the abolitionist movement. In this collection, Francione advances the most radical theory of animal rights to date. Unlike Peter Singer, Francione maintains that we cannot morally justify using animals under any circumstances, and unlike Tom Regan, Francione's (...) theory applies to all sentient beings, not only to those who have more sophisticated cognitive abilities.

Christine M. Korsgaard presents a compelling new view of our moral relationships to the other animals. She offers challenging answers to such questions as: Are people superior to animals, and does it matter morally if we are? Is it all right for us to eat animals, experiment on them, make them work for us, and keep them as pets?

This chapter discusses the application of the capabilities approach to the question of animal rights. It explains that this approach provides better theoretical guidance on the issue of animal entitlements over contractarian and utilitarian approaches because it is capable of recognising a wide range of types of animal dignity and of corresponding needs for flourishing. The chapter criticises the view of philosopher Immanuel Kant and his followers that mistreatment of animals does not raise questions of justice and suggests that the (...) claims of animals should be rooted in an understanding of what sorts of capabilities animals have.

Which nonhuman animals experience conscious pain?1 This question is central to the debate about animal welfare, as well as being of basic interest to scientists and philosophers of mind. Nociception—the capacity to sense noxious stimuli—is one of the most primitive sensory capacities. Neurons functionally specialized for nociception have been described in invertebrates such as the leech Hirudo medicinalis and the marine snail Aplysia californica (Walters 1996). Is all nociception accompanied by conscious pain, even in relatively primitive animals such as Aplysia, (...) or is it the case, as some philosophers continue to maintain, that conscious experiences are the exclu- sive province of human beings? What philosophical and scientific resources are presently available for assessing claims lying between these extremes? (shrink)

The debate on animal research has entered a new phase, involving a reevaluation of the moral status of animals, a detailed examination of the biological and philosophical meaning of animal pain and suffering, and a closer examination of the benefits of different types of knowledge. We need a clearer understanding of the ethical issues in animal research to provide the groundwork for public policy.

To be able to believe that a dog with a broken paw is not really in pain when it whimpers is a quite extraordinary achievement even for a philosopher. Yet according to the standard interpretaion, this is just what Descartes did believe. He held, we are informed, the ‘monstrous’ thesis that ‘animals are without feeling or awareness of any kind’. The Standard view has been reiterated in a recent collection on animal rights, which casts Descartes as the villain of the (...) piece for his alleged view that animals merely behave ‘ as if they feel pain when they are, say, kicked or stabbed’. The basis for this widely accepted interpretation is Descartes' famous doctrine of ‘animal machine’ ; a doctrine that one critic condemns as ‘a grim fortaste of a mechanically minded age’ which ‘brutally violates the old kindly fellowship of living things’.

Literature on the mental capacities and cognitive mechanisms of the great apes has been silent about whether they can act autonomously. This paper provides a philosophical theory of autonomy supported by psychological studies of the cognitive mechanisms that underlie chimpanzee behavior to argue that chimpanzees can act autonomously even though their psychological mechanisms differ from those of humans. Chimpanzees satisfy the two basic conditions of autonomy: (1) liberty (the absence of controlling influences) and (2) agency (self-initiated intentional action), each of (...) which is specified here in terms of conditions of understanding, intention, and self-control. In this account, chimpanzees make knowledge-based choices reflecting a richly information-based and socially sophisticated understanding of the world. Finally, two major theories of autonomy (Kantian theory and two-level theory) are rejected as too narrow to adequately address these issues, necessitating the modifications made in the present approach.

Did Descartes deny that animals can feel? While it has generally been assumed that he did, there has been some confusion over the fact that Descartes concedes to animals both sensations and passions'. John Cottingham, for example, has argued that while Descartes did insist that animals were automata, denying them thought and "self"-consciousness, none of these assertions entail the conclusion that animals do not feel. This paper examines both Cottingham's arguments and the relevant sections of Descartes' writings, concluding that Descartes (...) does indeed deny that animals are capable of feeling, but that for various reasons, this is not the brutal' and monstrous' view it is commonly assumed to be.

Among the "hard cases" of captive animal research is the continued use of chimpanzees in harmful experimental science. In a recent article I contend that contemporary animal welfare science and chimpanzee behavioral studies permit, if not require, a reappraisal of the moral significance of chimpanzee dissent from participation in certain experiments. In what follows, I outline my earlier argument, provide a brief survey of some central concepts in pediatric research ethics, and use these to enrich an understanding of chimpanzee dissent (...) useful for research ethics.

In an oft-quoted passage fromThe Principles of Morals and Legislation, Jeremy Bentham addresses the issue of our treatment of animals with the following words: ‘the question is not, Can theyreason? nor, can theytalk? but, Can theysuffer?’ The point is well taken, for surely if animals suffer, they are legitimate objects of our moral concern. It is curious therefore, given the current interest in the moral status of animals, that Bentham's question has been assumed to be merely rhetorical. No-one has seriously (...) examined the claim, central to arguments for animal liberation and animal rights, that animals actually feel pain. Peter Singer'sAnimal Liberationis perhaps typical in this regard. His treatment of the issue covers a scant seven pages, after which he summarily announces that ‘there are no good reasons, scientific or philosophical, for denying that animals feel pain’. In this paper I shall suggest that the issue of animal pain is not so easily dispensed with, and that the evidence brought forward to demonstrate that animals feel pain is far from conclusive.

Few human uses of nonhuman animals have incited as much controversy as the use of animals in biomedical research. The political exchanges over this issue tend to produce much more heat than light, as representatives of both biomedicine and the animal protection community accuse opponents of being and the like. However, a healthy number of individuals within these two communities offer the possibility of a more illuminating discussion of the ethics of animal research.

The risks of harm to nonhuman primates, and the absence of benefits for them, are critically important to decisions about nonhuman primate research. Current guidelines for review and practice tend to be permissive for nonhuman primate research as long as minimal welfare requirements are fulfilled and human medical advances are anticipated. This situation is substantially different from human research, in which risks of harms to the individual subject are typically reduced to the extent feasible. A risk threshold is needed for (...) the justification of research on nonhuman primates, comparable to the way risk thresholds are set for vulnerable human subjects who cannot provide informed consent. Much of the laboratory research conducted today has inadequate standards, leading to common physical, psychological, and social harms. (shrink)

Research studies and interventions sometimes offer potential benefits to subjects that compensate for the risks they face. Other studies and interventions, which I refer to as “nonbeneficial” research, do not offer subjects a compensating potential for benefit. These studies and interventions have the potential to exploit subjects for the benefit of others, a concern that is especially acute when investigators enroll individuals who are unable to give informed consent. US regulations for research with human subjects attempt to address this concern (...) by mandating strict protections for nonbeneficial research with subjects who cannot consent. Typically, humans who cannot consent, such as children, may be enrolled in nonbeneficial research only when it poses low risks and has the potential to gather information of sufficient value to justify the risks, an appropriate surrogate gives permission on the individual’s behalf and the individual agrees (assents). In contrast, US regulations for nonbeneficial research with nonhuman primates do not include these protections, even though it too involves subjects who cannot consent and who face risks for the benefit of others. Is this difference in regulatory protections justified? Or does the principle of fairness—treat like cases alike—imply that regulations for nonbeneficial research with nonhuman primates should include protections similar to those that apply to nonbeneficial research with humans who cannot consent? (shrink)

Human beings with diminished decision-making capacities are usually thought to require greater protections from the potential harms of research than fully autonomous persons. Animal subjects of research receive lesser protections than any human beings regardless of decision-making capacity. Paradoxically, however, it is precisely animals’ lack of some characteristic human capacities that is commonly invoked to justify using them for human purposes. In other words, for humans lesser capacities correspond to greater protections but for animals the opposite is true. Without explicit (...) justification, it is not clear why or whether this should be the case. Ethics regulations guiding human subject research include principles such as respect for persons—and related duties—that are required as a matter of justice while regulations guiding animal subject research attend only to highly circumscribed considerations of welfare. Further, the regulations guiding research on animals discount any consideration of animal welfare relative to comparable human welfare. This paper explores two of the most promising justifications for these differences␣between the two sets of regulations. The first potential justification points to lesser moral status for animals on the basis of their lesser capacities. The second potential justification relies on a claim about the permissibility of moral partiality as␣found in common morality. While neither potential justification is sufficient to justify the regulatory difference as it stands, there is possible common ground between supporters of some regulatory difference and those rejecting the current difference.

One of the most controversial areas of animal research is the use of nonhuman primates for fundamental research. At the centre of the controversy is the question of whether the benefits of research outweigh the harms. We argue that the evaluation of harms and benefits is highly problematic. We describe some common procedures in neurological research using nonhuman primates and the difficulties in evaluating the harm involved. Even if the harm could be quantified, it is unlikely that it could be (...) meaningfully aggregated over different procedures, let alone different animals. A similar problem arises for evaluating benefits. It is not clear how benefits could be quantified, and even if they could be, values for different aspects of expected benefits cannot be simply added up. Sorting harms and benefits in three or four categories cannot avoid the charge of arbitrariness and runs the risk of imposing its structure on the moral decision. The metaphor of weighing or balancing harms and benefits is inappropriate for the moral decision about whether to use nonhuman primates for research. Arguing that the harms and benefits in this context are incommensurable, we suggest describing the moral consideration of harms and benefits as a coherent trade-off. Such a decision does not require commensurability. It must be well-informed about the suffering involved and the potential benefits, it must be consistent with the legal, regulatory and institutional framework within which it is made, and it must cohere with other judgments in relevant areas.

Using an approach developed in the context of human bioethics, we argue that chimpanzees in research can be regarded as vulnerable subjects. This vulnerability is primarily due to communication barriers and situational factors—confinement and dependency—that make chimpanzees particularly susceptible to risks of harm and exploitation in experimental settings. In human research, individuals who are deemed vulnerable are accorded special protections. Using conceptual and moral resources developed in the context of research with vulnerable humans, we show how chimpanzees warrant additional safeguards (...) against harm and exploitation paralleling those for human subjects. These safeguards should include empowering third parties to act as surrogate decision makers for chimpanzees, ensuring participant “assent,” and avoiding recruitment of animal subjects based merely on convenience.

The Weatherall report on the use of non-human primates in research was published in 2006. Its main conclusion was that there is a strong scientific case for the use of non-human primates in some cases, but the report stressed the importance of evaluating each case in the light of the availability of alternatives. In addition to arguing for the scientific necessity of using non-human primates in research, the report also provided an ethical justification. As could be expected, the report was (...) harshly criticised by animal rights groups, but in the academic literature, only two critical replies appeared. In what follows, I will describe the ethical justification for non-human primate research as it is laid out in the Weatherall report and then consider the criticism in the academic literature. I conclude that the report’s ethical justification for the use of non-human primates in research, in particular in basic neuroscientific research, has not been convincingly challenged by its critics. Since the criticism of the report is limited and represents only a small part of the academic discussion about the use of non-human primates in research, and a still smaller part of the ethical discussion about animal research, it is important that the discussion continue both at the academic and social level.

In the relatively short time since 2006—when Theoretical Medicine and Bioethics published an issue on moral issues relevant to the use of nonhuman animals in research [1]—significant changes have occurred for nonhuman animals in many quarters. Public sentiment, new policy initiatives, and scientific studies of nonhuman animals’ capacities have all influenced the ways in which nonhuman animals are perceived and treated in research. Today, a large body of information is available for use in decision making about the acceptability of using (...) nonhuman animals in research. The articles in this issue assess how moral argument and empirical studies stand to guide animal research policies and practices in future years.Many in bioethics have come to regard issues of animal research as a subfield of research ethics, bringing it closer to human research ethics. Animal ethics, like public health ethics, has struggled for recognition in bioethics. As the contributions to this issue show, some in bioe. (shrink)

Animal research has long been a source of biomedical aspirations and moral concern. Examples of both hope and concern are abundant today. In recent months, as is common practice, monkeys have served as test subjects in promising preclinical trials for an Ebola vaccine or treatment 1 , 2 , 3 and in controversial maternal deprivation studies. 4 The unresolved tension between the noble aspirations of animal research and the ethical controversies it often generates motivates the present issue of the Cambridge (...) Quarterly of Healthcare Ethics. As editors of this special section, we hope that these original and timely articles will push the professional discussion of animal research ethics in a positive direction that will benefi t research scientists and others interested in moral problems in animal research. We also look forward to a day when animal research will genuinely meet both appropriate scientifi c and appropriate ethical criteria—criteria that themselves can be improved by critical scrutiny. Animal research—that is, the use of live animals as experimental subjects in biomedical and behavioral fi elds of learning—has been deeply entrenched for well over half a century. One signal development was the enactment in the late 1930s of federal product safety legislation in the United States and other nations that required animal testing of food, drugs, and medical devices prior to use by human subjects or consumers. 5 Another development was the publication of codes of research ethics that called for animal research prior to human research. The Nuremberg Code, published by an American military tribunal in 1947–48 after scrutiny of Nazi medical atrocities, stated that experiments involving the use of human subjects should be " based on the results of animal experimentation. " 6 The Declaration of Helsinki, fi rst published in 1964, reaffi rmed this assumption and added, rather imprecisely, that " the welfare of animals used for research must be respected. " 7 Against the background of such statements, the institutionalization and widespread acceptance of animal research in the twentieth century rested on two basic assumptions, one factual and one moral. The factual assumption was that animal research is suffi ciently reliable as a basis for predicting the effects of drugs, products, and other materials on human beings that animal trials can be expected to yield signifi cant scientifi c conclusions and medical benefi ts to humanity.

A common assumption in the selection of nonhuman animal subjects for research and the approval of research is that, if the risks of a procedure are too great for humans, and if there is a so-called scientific necessity, then it is permissible to use nonhuman animal subjects. I reject the common assumption as neglecting the central ethical issue of the permissibility of using nonhuman animal subjects and as being inconsistent with the principle of justice used in human subjects research ethics. (...) This principle requires that certain classes of individuals not be subjected to a disproportionate share of the burdens or risks of research. I argue for an extension of this principle to nonhuman animal research and show that a prima facie violation of the principle occurs because nonhuman animals bear an overwhelmingly disproportionate share of the risks of research without sufficient justification or reciprocal benefit.

Contrary to longstanding opinion, Descartes does not deny all feeling and awareness to non-human animals. Though he undoubtedly denies that animals think, a case can be made that he nonetheless would allow them organism consciousness, perceptual consciousness, access consciousness and even phenomenal con- sciousness. Descartes does not employ or accept an ‘all-or-nothing’ view of consciousness. He merely denies (not that this is a small thing) that animals have the capacity for self-conscious reflective reception or awareness of sensations and feelings.

In the wake of the chimpanzee genome publication, Pascal Gagneux, James J. Moore and Ajit Varki consider the ethical and scientific challenges for scientists who work on captive great apes.

The invocation of moral rights in moral/social debate today is a recipe for deadlock in our consideration of substantive issues. How we treat animals and humans in part should derive from the value of their lives, which is a function of the quality of their lives, which in turn is a function of the richness of their lives. Consistency in argument requires that humans with a low quality of life should be chosen as experimental subjects over animals with a higher (...) quality of life. (shrink)

Should monkeys be used in painful and often deadly infectious disease research that may save many human lives? This is the challenging question that Anne Barnhill, Steven Joffe, and Franklin G. Miller take on in their carefully argued and compelling article “The Ethics of Infection Challenges in Primates.” The authors offer a nuanced and even-handed position that takes philosophical worries about nonhuman primate moral status seriously and still appreciates the very real value of such research for human welfare. Overall, they (...) argue for an extension and revision of the recommendations regarding chimpanzee research offered by the Institute of Medicine in 2011; the practical upshot of their argument would allow for infection challenge research for promising interventions for Ebola and Marburg virus diseases but not for smallpox or the common cold. The IOM recommendations regarding chimpanzee research put in motion an exceptionalist policy for this great ape population. Barnhill and colleagues’ proposal would enlarge the scope of that exceptionalism to embrace NHPs other than great apes. But is such exceptionalism warranted? It is not obvious to me either that the more sophisticated capacities of a species as a whole give it greater ethical protections or that less intellectually or socially sophisticated animals ought to therefore receive less protection when it comes to painful experimental interventions.

In this article, I argue that it is wrong to conduct any experiment on a nonhuman which we would regard as immoral were it to be conducted on a human, because such experimentation violates the basic moral rights of sentient beings. After distinguishing the rights approach from the utilitarian approach, I delineate basic concepts. I then raise the classic “argument from marginal cases” against those who support experimentation on nonhumans but not on humans. After next replying to six important objections (...) against that argument, I contend that moral agents are logically required to accord basic moral rights to every sentient being. I conclude by providing criteria for distinguishing ethical from unethical experimentation. (shrink)
