In this essay I argue that the evolutionary and comparative study of nonhuman animal (hereafter animal) cognition in a wide range of taxa by cognitive ethologists can readily inform discussions about animal protection and animal rights. However, while it is clear that there is a link between animal cognitive abilities and animal pain and suffering, I agree with Jeremy Bentham who claimed long ago the real question does not deal with whether individuals can think or reason but rather with whether (...) or not individuals can suffer. One of my major goals will be to make the case that the time has come to expand. The Great Ape Project (GAP) to The Great Ape/Animal Project (GA/AP) and to take seriously the moral status and rights of all animals by presupposing that all individuals should be admitted into the Community of Equals. I also argue that individuals count and that it is essential to avoid being speciesist cognitivists; it really doesn't matter whether ‘dogs ape’ or whether ‘apes dog’ when taking into account the worlds of different individual animals. Narrow-minded primatocentrism and speciesism must be resisted in our studies of animal cognition and animal protection and rights. Line-drawing into ‘lower’ and ‘higher’ species is a misleading speciesist practice that should be vigorously resisted because not only is line-drawing bad biology but also because it can have disastrous consequences for how animals are viewed and treated. Speciesist line-drawing also ignores within species individual differences. (shrink)

It seems impossible for a human being not to have some point of view concerning nonhuman animal (hereafter animal) welfare. Many people make decisions about how humans are permitted to treat animals using speciesist criteria, basing their decisions on an individual's species membership rather than on that animal's individual characteristics. Although speciesism provides a convenient way for making difficult decisions about who should be used in different types of research, we argue that such decisions should rely on an analysis of (...) individual characteristics and should not be based merely on species membership. We do not argue that the concept of species is never useful or important. To make our points, we present a conversation among a skeptic, an agnostic, and a proponent of the view that our moral obligations to an animal must be based on an analysis of that individual's characteristics. In the course of the discussion, concepts such as personhood, consciousness, cognitive ability, harm, and pain are presented, because one's understanding of these concepts informs his or her ethical decisions about the use of animals by humans.

Bonnie Steinbock argues that Peter Singer has made an important contribution to remind us that animals deserve very special consideration, but that he fails to make a compelling case against "speciesism.".

As we begin our exploration of our relationship with animals, we come face to face with Peter Singer and his insistence that speciesism is a vice. It is important to come to know what he means by speciesism, why he regards it as a moral mistake.

This paper offers several criticisms of the account of rightholding laid out in S. Matthew Liao’s recent paper “The Basis of Human Moral Status.” I argue that Liao’s account both does too much and too little: it grants rightholder status to those who may not deserve it, and it does not provide grounds for offering such status to those who arguably do deserve it. Given these troubling aspects of his approach, I encourage Liao to abandon his “physical basis of moral (...) agency” account of moral status and instead adopt a position closer to a traditional “speciesist” view.

My contention is that virtue ethics offers an important critique of traditional philosophical conceptions of moral status as well as an alternative view of important moral issues held to depend on moral status. I argue that the scope of entities that deserve consideration depends on our conception of the demands of virtues like justice; which entities deserve consideration emerges from a moral view of a world shaped by that conception. The deepest disputes about moral status depend on conflicting conceptions of (...) justice. I advocate a conception of the virtue of justice that can account for the cases that pose problems for the legalistic views of moral status and discuss what ideal moral debate looks like on this view.

In spite of the considerable literature nowadays existing on the issue of the moral exclusion of nonhuman animals, there is still work to be done concerning the characterization of the conceptual framework with which this question can be appraised. This paper intends to tackle this task. It starts by defining speciesism as the unjustified disadvantageous consideration or treatment of those who are not classified as belonging to a certain species. It then clarifies some common misunderstandings concerning what this means. Next, (...) it rejects the idea that there are different kinds of speciesism. Such an idea may result from confusion because there are (1) different ways in which speciesism can be defended; and (2) different speciesist positions, that is, different positions that assume speciesism among their premises. Depending on whether or not these views assume other criteria for moral consideration apart from speciesism, they can be combined or simple speciesist positions. But speciesism remains in all cases the same idea. Finally, the paper examines the concept of anthropocentrism, the disadvantageous treatment or consideration of those who are not members of the human species. This notion must be conceptually distinguished from speciesism and from misothery (aversion to nonhuman animals). Anthropocentrism is shown to be refuted because it either commits a petitio principia fallacy or it falls prey to two arguments: the argument from species overlap (widely but misleadingly known as “argument from marginal cases”) and the argument from relevance. This rebuttal identifies anthropocentrism as a speciesist view. (shrink)

A better appreciation of Kant’s commitments in a variety of disciplines reveals Kant had a deeper understanding of human and non-human animals than generally recognized, and this sheds new light on Kant’s claims about the nature and scope of moral status and helps to address, at least from Kant’s perspective, many of the familiar objections to his notorious account of “duties regarding animals.” Kant’s core principles about the nature of moral obligation structure his thoughts about the moral status of human (...) beings and non-human animals. Kant’s commitments in biology, psychology, anthropology and physical geography support his account of the nature of and distinction between humans and non-human animals. This account supports Kant’s judgment that we have duties to every human being and significant duties regarding non-human animals, duties which involve direct concern for animals because of their nature. A comparison of Kant’s account with some recently proposed Kantian alternatives provides additional perspective on some of the distinctive features, and strengths and weaknesses, of Kant’s approach.

This is a review essay of Jeff McMahan's recent book The Ethics of Killing: Problems at the Margins of Life (OUP: 2002). In the first part, I lay out the central features of McMahan's account of the wrongness of killing and its implications for when it is permissible to kill. In the second part of the essay, I argue that we ought not to accept McMahan's rejection of species membership as having any bearing on whether it is permissible to kill (...) a particular individual, as there are ways of understanding its relevance that are more plausible than McMahan allows.

Anti-vivisectionists charge that animal experimenters are speciesists people who unjustly discriminate against members of other species. Until recently most defenders of experimentation denied the charge. After the publication of `The Case for the Use of Animals in Biomedical Research' in the New England Journal of Medicine , experimenters had a more aggressive reply: `I am a speciesist. Speciesism is not merely plausible, it is essential for right conduct...'1. Most researchers now embrace Cohen's response as part of their defense of animal (...) experimentation. Cohen asserts that both rights and utilitarian arguments against the use of animals in research fail because they `refuse to recognize the moral differences among species'.2 If we appreciate the profound differences between humans and non-human animals, he says, we would understand why animals do not and could not have rights and why animal pain does not have as much moral weight as human pain. Animal liberationists think speciesism is immoral because they mistakenly equate it with racism and sexism. Cohen claims this equation is `unsound', `atrocious', `utterly specious', and `morally offensive'. Doubtless Cohen is right that the charge of speciesism is founded on an analogy with racism and sexism. He is mistaken, however, in asserting that the comparison is categorically illicit. (shrink)

Biomedical researchers claim there is significant biomedical information about humans which can be discovered only through experiments on intact animal systems (AMA p. 2). Although epidemiological studies, computer simulations, clinical investigation, and cell and tissue cultures have become important weapons in the biomedical scientists' arsenal, these are primarily "adjuncts to the use of animals in research" (Sigma Xi p. 76). Controlled laboratory experiments are the core of the scientific enterprise. Biomedical researchers claim these should be conducted on intact biological systems, (...) whole animals. By observing the effects of various stimuli in non-human animals, we can form legitimate expectations about the likely effects of these stimuli in humans. Perhaps more importantly, we can understand the biomedical condition's causal mechanisms. (shrink)

This paper reviews the argument by Peter Singer that speciesism, the exploitation of other species without regard for their interests, is as morally objectionable as racism and sexism. Objections to this argument by philosophers such as Peter Carruthers, Mary Midgley, and Cora Diamond as well as conventional wisdom about notions of species differences are presented and critically examined. I conclude that Alaine Locke would have supported Singer's expansion of the moral circle.

Many people in the animal welfare communityhave argued that the use of nonhuman animals inmedical research is necessarily based onspeciesism, an unjustified prejudice based onspecies membership. As such it is morally akinto racism and sexism. This is misguided. Thecombined capacities for autonomy and sentiencewith the obligations derived from relationssupport a morally justifiable rationale forusing some nonhuman animals in order to limitthe risk of harm to humans. There may be a fewcases where it is morally better to use a neversentient human (...) than a sentient animal, butthese cases are few and would not fulfill thecurrent need for research subjects. The use ofnonautonomous animals instead of humans inrisky research can be based on solid moralground. It is not necessarily speciesism. (shrink)

During nearly two millennia of European history in which Christian dogmas could not be questioned, many prejudices put down deep roots. Humanists are, rightly, critical of Christians who have not freed themselves of these prejudices-for example, against the equality of women or against nonreproductive sex. It is curious, therefore, that, despite many individual exceptions, humanists have on the whole been unable to free themselves from one of the most central of these Christian dogmas: the prejudice of speciesism.

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)

Definition: considering human beings to be of central importance; the source of value.

Marginal humans are not rational yet we still think they are morally considerable. This is inconsistent with denying animals moral status on the basis of their irrationality. Therefore, either marginal humans and animals are both morally considerable or neither are. In this paper I consider a major objection to this argument: that species is a relevant difference between humans animals.

Rationality (or something similar) is usually given as the relevant difference between all humans and animals; the reason humans do but animals do not deserve moral consideration. But according to the Argument from Marginal Cases not all humans are rational, yet if such (marginal) humans are morally considerable despite lacking rationality it would be arbitrary to deny animals with similar capacities a similar level of moral consideration. The slippery slope objection has it that although marginal humans are not strictly speaking (...) morally considerable, we should give them moral consideration because if we do not we will slide down a slippery slope where we end up by not giving normal humans due consideration. I argue that this objection fails to show that marginal humans have the kind of direct moral status proponents of the slippery slope argument have in mind. (shrink)

The fact that humans have a special relationship to each other insofar as they belong in the same species is often taken to be a morally relevant difference between humans and other animals, one which justifies a greater moral status for all humans, regardless of their individual capacities. I give some reasons why this kind of relationship is not an appropriate ground for differential treatment of humans and nonhumans. I then argue that even if relationships do matter morally species membership (...) cannot justify a difference in moral status. This has important implications because it removes one barrier to giving animals greater moral status. (shrink)

In this paper I will examine two responses to the argument from marginal cases; the argument from kinds and the similarity argument. I will argue that these arguments are insufficient to show that all humans have moral status but no animals do. This does not prove that animals have moral status but it does shift the burden of proof onto those who want to maintain that all humans are morally considerable, but no animals are.

If we are going to treat other species so very differently from our own — killing, eating and experimenting on pigs and sheep, for example, but never human beings — then it seems we need to come up with some morally relevant difference between us and them that justifies this difference in treatment. Otherwise it appears we are guilty of bigotry (in just the same way that someone who discriminates on the basis of race or sex is guilty of bigotry). (...) But what is this morally relevant difference? Julia Tanner's article examines, and rejects, some of the most popular answers to this question. -/- . (shrink)

Properly understood speciesism regards membership in one's own species (e.g., being a fellow human being) as sufficient for sharing one's own moral status, but NOT as being necessary. Speciesism is consistent with any of a great range of attitudes toward alter-specific animals. When nonhuman animals are accorded a lesser moral status it is not per se because they are not human.

“Speciesism” accords greater value to human beings and their interests. It is supposed to be opposed to a liberationist stance, since it is precisely the numerous forms of discounting of animal interests which liberationists oppose. This association is mistaken. In this paper I claim that many forms of speciesism are consistent with upholding a robust liberationist agenda. Accordingly, several hotly disputed topics in animal ethics can be set aside. The significance of such clarification is that synthesizing liberationism with speciesism substantially (...) modifies some of the coordinates of the debates over animal ethics. Secondly, defusing some counterintuitive implications of liberationism may make liberationism more popular than it currently is. Liberationism would no longer demand the eradication of ingrained speciesist intuitions. The paper finally presents a form of speciesism that does oppose liberationism, but is too strong and (fortunately) shared by few. (shrink)
