It has been argued that some animals are moral subjects, that is, beings who are capable of behaving on the basis of moral motivations. In this paper, we do not challenge this claim. Instead, we presuppose its plausibility in order to explore what ethical consequences follow from it. Using the capabilities approach, we argue that beings who are moral subjects are entitled to enjoy positive opportunities for the flourishing of their moral capabilities, and that the thwarting of these capabilities entails (...) a harm that cannot be fully explained in terms of hedonistic welfare. We explore the implications of this idea for the assessment of current practices involving animals. (shrink)

Most people believe that suffering is intrinsically bad. In conjunction with facts about our world and plausible moral principles, this yields a pro tanto obligation to reduce suffering. This is the intuitive starting point for the moral argument in favor of interventions to prevent wild animal suffering. If we accept the moral principle that we ought, pro tanto, to reduce the suffering of all sentient creatures, and we recognize the prevalence of suffering in the wild, then we seem committed to (...) the existence of such a pro tanto obligation. Of course, competing values such as the aesthetic, scientific or moral values of species, biodiversity, naturalness or wildness, might be relevant to the all-things-considered case for or against intervention. Still, many argue that, even if we were to give some weight to such values, no plausible theory could resist the conclusion that WAS is overridingly important. This article is concerned with large-scale interventions to prevent WAS and their tractability and the deep epistemic problem they raise. We concede that suffering gives us a reason to prevent it where it occurs, but we argue that the nature of ecosystems leaves us with no reason to predict that interventions would reduce, rather than exacerbate, suffering. We consider two interventions, based on gene editing technology, proposed as holding promise to prevent WAS; raise epistemic concerns about them; discuss their potential moral costs; and conclude by proposing a way forward: to justify interventions to prevent WAS, we need to develop models that predict the effects of interventions on biodiversity, ecosystem functioning, and animals’ well-being.

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.

Most people agree that inflicting unnecessary suffering upon animals is wrong. Many fewer people, including among ethicists, agree that painlessly killing animals is necessarily wrong. The most commonly cited reason is that death (without pain, fear, distress) is not bad for them in a way that matters morally, or not as significantly as it does for persons, who are self-conscious, make long-term plans and have preferences about their own future. Animals, at least those that are not persons, lack a morally (...) significant interest in continuing to live. At the same time, some argue that existence itself can be good, insofar as one’s life is worth living. For animals, a good life can offset a quick, if early, death. So, it seems to follow that breeding happy animals that will be (prematurely) killed can be a good thing overall. Insofar as slaughter and sale makes it economically sustainable to raise new ones, who would otherwise not exist, raising and killing animals for food who will have lives worth living is good overall. It benefits them as well as consumers, and makes the world better by adding to the sum of happiness. The process of raising and killing animals with positive welfare produces a sequence of replacement that maintains or increases overall welfare, all else being equal (assuming in particular no overall negative impact on the welfare of other parties). Call this the Replaceability Argument (RA) and the ensuing controversy the Replaceability Problem (RP). This is a problem at the crossroads of the ethics of killing, agricultural ethics, procreation ethics, and population ethics. (shrink)

In Animal Ethics in Context, Clare Palmer tries to harmonise two competing approaches to animal ethics. One focuses on the morally relevant capacities that animals possess. The other is the Laissez-Faire Intuition (LFI): the claim that we have duties to assist domesticated animals but should (at least generally) leave wild animals alone. In this paper, I critique the arguments that Palmer offers in favour of the No-Contact LFI - the view that we have (prima facie) duties not to harm wild (...) animals but no duties to assist them. I argue that Palmer's endorsement of the No-Contact LFI is unwarranted. Her arguments actually provide strong reasons to endorse what I call the Gradient View - a position that posits weak presumptive duties to assist wild animals that become stronger as our relations with the animals grow stronger.

ABSTRACTThis paper explores the international implications of liberal theories which extend justice to sentient animals. In particular, it asks whether they imply that coercive military intervention in a state by external agents to prevent, halt or minimise violations of basic animal rights can be justified. In so doing, it employs Simon Caney's theory of humanitarian intervention and applies it to non-human animals. It argues that while humane intervention can be justified in principle using Caney's assumptions, justifying any particular intervention on (...) behalf of animals is much more difficult – and in present circumstances impossible. If these claims are correct, a number of important conclusions follow. First, all states lack legitimacy because of the horrors that they inflict upon animals. As a result of this, all states are prima facie liable to intervention by external agents. To remedy this situation, all states have the responsibility to massively transform their relationsh...

In The Case for Animal Rights, Tom Regan argues that although all subjects-of-a-life have equal inherent value, there are often differences in the value of lives. According to Regan, lives that have the highest value are lives which have more possible sources of satisfaction. Regan claims that the highest source of satisfaction, which is available to only rational beings, is the satisfaction associated with thinking impartially about moral choices. Since rational beings can bring impartial reasons to bear on decision making, (...) Regan maintains that they have an additional possible source of satisfaction that nonrational beings do not have and, consequently, the lives of rational beings turn out to have greater value..

In recent discussions, it has been argued that a theory of animal rights is at odds with a liberal abortion policy. In response, Francione (1995) argues that the principles used in the animal rights discourse do not have implications for the abortion debate. I challenge Francione’s conclusion by illustrating that his own framework of animal rights, supplemented by a relational account of moral obligation, can address the moral issue of abortion. I first demonstrate that Francione’s animal rights position, which grounds (...) moral consideration in sentience, is committed to the claim that a sentient fetus has a right to life. I then illustrate that a fully developed account of animal rights that recognizes the special obligations humans have to assist animals when we cause them to be dependent and vulnerable through our voluntary actions or omissions is committed to the following: a woman also has a special obligation to assist a sentient fetus when she causes it to be dependent and vulnerable through her voluntary actions or omissions. From these considerations, it will become evident that a fully developed and consistent animal rights ethic does in fact have implications for the abortion discussion. (shrink)

Over the past century, animal agriculture in the United States has transformed from a system of small, family farms to a largely industrialized model—often known as ‘industrial farm animal production’ (IFAP). This model has successfully produced a large supply of cheap meat, eggs and dairy products, but at significant costs to animal welfare, the environment, the risk of zoonotic disease, the economic and social health of rural communities, and overall food abundance. Over the past 40 years, numerous critiques of IFAP (...) have been published, for both academic and non-academic audiences, mostly focusing on our obligations to animals. Here we offer a comprehensive critique of IFAP, focusing not only on our obligations to animals, but also important environmental, social, economic, and public health concerns. Our cumulative argument proceeds in five steps: (1) we briefly review the structure and key characteristics of IFAP; (2) we review the adverse effects of IFAP; (3) we review the historical development and positive rationale for IFAP; (4) we summarize previous moral critiques of IFAP, as well as defenses of it; and (5) we offer a moral critique of IFAP based on the common morality, and in particular on a principle of nonmaleficence, which we take to be the least controversial argument.

In contemporary times, wildlife managers attempt to provide solutions to problems arising from conflicting uses of the environment by humans and nonhuman animals. Within the Kangaroo Management Zones of New South Wales , the commercial culling "solution" is one such attempt to perpetuate kangaroo populations on pastoral land while supporting farmers in continuing inefficient sheep farming. Because wildlife management rests on a distinction between the "nature" of humans and animals, then humanist attention to standards of individual welfare need not interrupt (...) the process whereby individual animals are killed within an economic framework designed to improve habitat management for the conservation of their populations. Building on Thorne's discussion of the meanings scripted onto individual kangaroo bodies, this paper explores the utilitarian underpinnings of the commercialization approach and considers the ethical implications of constructing the population as resource, even if this results in an improvement in the welfare of individual kangaroos.

Animal welfare has been conceptualized in such a way that the use of animals in science and for food seems justified. I argue that those who have done this have appropriated the concept of animal welfare, claiming to give a scientific account that is more objective than the sentimental account given by animal liberationists. This strategy seems to play a major role in supporting merely limited reform in the use of animals and seems to support the assumption that there are (...) conditions under which animals may be raised and slaughtered for food that are ethically acceptable. Reformists do not need to make this assumption, but they tend to conceptualize animal welfare is such a way that death does not count as harmful to the interests of animals, nor prolonged life a benefit. In addition to this prudential value assumption, some members of this community have developed strategies for defending suitably reformed farming practices as ethical even granting that death and some other forms of constraints are harms. One such strategy is the fiction of a domestic contract. However, if one accepts the conceptualization of human welfare give by L. W. Sumner, and applies it to animals in the way that I think is justified, an accurate conceptualization of animal welfare has different implications for which uses of animals should be regarded as ethically acceptable. In this paper I give an historical and philosophical account of animal welfare conceptulization and use this account to argue that animal breeders, as custodians of the animals they breed, have the ethical responsibility to help their animal wards achieve as much autonomy as possible in choosing the form of life made available to them and to provide that life. Attempts to avoid these implications by alluding to a contract model of the relationship between custodians and their wards fail to relieve custodians of their ethical responsibilities of care.

Invertebrate animals are usually seen as a kind of “aliens” which do not deserve any moral consideration. However, there is a growing amount of evidenceindicating that many of them do have the capacity to experience pain. The samecriteria that are usually applied in order to infer that vertebrates are sentient beings (behavioral response, learning capacity, memory, a certain specific neurophysiological structure…) lead to the idea that many invertebrates aresentient as well. Therefore, under the skeptical premise that we have no directevidence (...) of the experience of pain in vertebrates, we are forced to hold that itexists in both vertebrates and invertebrates.

Este artículo pretende revisar el concepto de responsabilidad moral frente a los animales y el medio ambiente; para ello se toman en cuenta algunas revisiones necesarias del concepto de responsabilidad, a saber, la posibilidad de entender un concepto de responsabilidad parcial, así como la necesidad de poder hacer responsables moralmente tanto a individuos como a colectivos. Estos conceptos se estudian en un análisis diferenciado entre la responsabilidad moral frente a los animales y frente a la naturaleza.

Some philosophers have argued that moral agency is characteristic of humans alone and that its absence from other animals justifies granting higher moral status to humans. However, human beings do not have a monopoly on moral agency, which admits of varying degrees and does not require mastery of moral principles. The view that all and only humans possess moral agency indicates our underestimation of the mental lives of other animals. Since many other animals are moral agents (to varying degrees), they (...) are also subject to (limited) moral obligations, examples of which are provided in this paper. But, while moral agency is sufficient for significant moral status, it is by no means necessary. (shrink)

: Recent work in the area of ethics and animals suggests that it is philosophically legitimate to ascribe emotions to nonhuman animals. Furthermore, it is sometimes argued that emotionality is a morally relevant psychological state shared by humans and nonhumans. What is missing from the philosophical literature that makes reference to emotions in nonhuman animals is an attempt to clarify and defend some particular account of the nature of emotion, and the role that emotions play in a characterization of human (...) nature. I argue in this paper that some analyses of emotion are more credible than others. Because this is so, the thesis that humans and nonhumans share emotions may well be a more difficult case to make than has been recognized thus far. (shrink)

To study animal welfare empirically we need an objective basis for deciding when an animal is suffering. Suffering includes a wide range ofunpleasant emotional states such as fear, boredom, pain, and hunger. Suffering has evolved as a mechanism for avoiding sources ofdanger and threats to fitness. Captive animals often suffer in situations in which they are prevented from doing something that they are highly motivated to do. The an animal is prepared to pay to attain or to escape a situation (...) is an index ofhow the animal about that situation. Withholding conditions or commodities for which an animal shows (i.e., for which it continues to work despite increasing costs) is very likely to cause suffering. In designing environments for animals in zoos, farms, and laboratories, priority should be given to features for which animals show inelastic demand. The care ofanimals can thereby be based on an objective, animal-centered assessment of their needs. (shrink)

In the debate over the moral status of nonsentient organisms, biocentrists argue that all living things, including nonsentient ones, have interests of their own. They often defend this claim by arguing that living organisms are goal-directed, functionally organized systems. This argument for ascribing interests has faced a serious challenge that is sometimes called the Problem of Scope. Critics have argued that ascribing interests on the basis of functional organization would have implausible implications regarding the scope of the argument, such as (...) ascribing interests to inanimate artifacts and machines. In this paper, I argue that much of the recent discussion on the Problem of Scope is based on an uncharitable interpretation of the argument for ascribing interests, which presupposes a reductionist account of functions. I assess this version of the argument, and explain why it cannot succeed. I then consider an alternative interpretation of the argument, which appeals to a non-reductionist account of functions. I argue that this version of the argument avoids the Problem of Scope, while acknowledging that it has limitations of its own. (shrink)

This paper addresses a question about the moral status of Artificial Intelligence (AI): will AIs ever become moral patients? I argue that, while it is in principle possible for an intelligent machine to be a moral patient, there is no good reason to believe this will in fact happen. I start from the plausible assumption that traditional artifacts do not meet a minimal necessary condition of moral patiency: having a good of one's own. I then argue that intelligent machines are (...) no different from traditional artifacts in this respect. To make this argument, I examine the feature of AIs that enables them to improve their intelligence, i.e., machine learning. I argue that there is no reason to believe that future advances in machine learning will take AIs closer to having a good of their own. I thus argue that concerns about the moral status of future AIs are unwarranted. Nothing about the nature of intelligent machines makes them a better candidate for acquiring moral patiency than the traditional artifacts whose moral status does not concern us. (shrink)

This paper presents some of the most promising ways wild animals are currently being helped, as well as other ways of helping that may be implemented easily in the near future. They include measures to save animals affected by harmful weather events, wild animal vaccination programs, and projects aimed at reducing suffering among synanthropic animals. The paper then presents other ways of helping wild animals that, while noncontroversial, may reduce aggregate suffering at the ecosystem level. The paper argues that impracticability (...) and normative objections against reducing wild animal suffering fail against these ways of helping wild animals. (shrink)

Many philosophers accept both of the following claims: (1) consciousness matters morally, and (2) species membership doesn’t matter morally. In other words, many reject speciesism but accept what we might call 'sentientism'. But do the reasons against speciesism yield analogous reasons against sentientism, just as the reasons against racism and sexism are thought to yield analogous reasons against speciesism? This paper argues that speciesism is disanalogous to sentientism (as well as racism and sexism). I make a case for the following (...) asymmetry: (a) some non-humans clearly have interests, but (b) no non-conscious entities clearly have interests. This asymmetry, I argue, renders sentientism resistant to the standard argument against speciesism. (shrink)

The paper begins with a description of a grey seal performing conspecific infanticide. The paper then gives an account of “nobleness” and “brutishness.” Roughly, a behavioural-disposition is noble/brutish if it is one that would be a moral virtue/vice if the possessor of the behavioural-disposition were a moral agent. The paper then advances two pairs of axiological claims. The first pair of claims is that nobleness is good and that brutishness is bad. The second pair of claims is about an axiological (...) interaction between nobleness/brutishness and well-being. That any non-human animal lacks well-being is bad. Yet, it is worse that a noble non-human animal lacks well-being, and not so bad that a brutish non-human animal lacks well-being. Lastly, the paper discusses some potential moral implications of these axiological claims, for instance that factory farming is especially wrong because it causes noble non-human animals to lack well-being.

Cultured meat, like any new technology, raises inevitable ethical issues. For example, on animal ethics grounds, it may be argued that reformed livestock farming in which animals’ lives are worth living constitutes a better alternative than cultured meat, which, along with veganism, implies the extinction of farm animals. Another ethical argument is that, just as we would undermine human dignity by producing and consuming meat that is grown from human cells, eating meat that is grown from nonhuman animal cells would (...) violate animal dignity because it is a way to create an us and them, which would make veganism the only ethical option. The present study challenges this argument. First, I examine the fundamental issue of whether cultured meat provides such an attack on animal dignity. The second issue is whether, assuming that it is true that cultured meat undermines animal dignity, it would be acceptable to reject cultured meat even though this implies sacrificing nonhuman animals.

Moral status is the moral value that something has in its own right, independently of the interests or concerns of others. Research using human embryonic stem cells implicates issues about moral status because the current method of extracting hESCs involves the destruction of a human embryo, the moral status of which is contested. Moral status issues can also arise, however, when hESCs are transplanted into embryonic or fetal animals, thereby creating human/ nonhuman stem cell chimeras. In particular, one concern about (...) chimera research is that it could confer upon an animal the moral status of a normal human adult, but then impermissibly fail to accord the animal the protections it merits in virtue of its enhanced status. Understanding the public policy implications of this ethical conclusion is complicated by the fact that certain views about the moral status of the embryo cannot legitimately be used to justify public policy decisions. Arguments like those employed in the abortion debate for the conclusion that abortion should be legally permissible even if abortion is not morally permissible also support, to a more limited degree, a liberal policy on hESC research involving the creation of chimeras.

It is argued that the question of whether or not one is required to be or become a strict vegetarian depends, not upon a rule or ideal that endorses vegetarianism on moral grounds, but rather upon whether one's own physical, biological nature is adapted to maintaining health and well-being on a vegetarian diet. Even if we accept the view that animals have rights, we still have no duty to make ourselves substantially worse off for the sake of other rights-holders. Moreover, (...) duties to others, such as fetuses and infants, may require one to consume meat or animal products. Seven classes of individuals who are not required to be or become vegetarians are identified and their examption is related to nutritional facts; these classes comprise most of the earth's population. The rule of vegetarianism defines a special or provisional duty rather than any general or universal rule, since its observance it based upon the biological capacities of individual humans whose genetic constitution and environment makes them suitably herbivorous. It is also argued that generalizing the vegetarian ideal as a social goal for all would be wrongful because it fails to consider the individual nutritional needs of humans at various stages of life, according to biological differences between the sexes, and because it would have the eugenic effect of limiting the adaptability of the human species. The appeal to the natural interests of omnivores will not justify any claim that humans may eat amounts of meat or animal products in excess of a reasonable safety margin since animals have rights-claims against us.

Many philosophers have argued against Singer’s claim that all animals are equal. However, none of these responses have demonstrated an appreciation of the complexity of his position. The result is that all of these responses focus on one of his arguments in a way that falls victim to another. This paper is a critical examination of a possible response to the full complexity of Singer’s position that derives from the work of Carl Cohen, Kathleen Wilkes, and F. Ramsey. On this (...) response, a being’s moral status depends not on the capacities and abilities she does in fact have, but instead on the capacities and abilities normal for the members of her species. However, this response is ultimately unacceptable, for it depends on a faulty conception of loss and misfortune and its underlying moral principle is irrational at best and morally objectionable at worst. The failure of even this response to Singer gives us good reason to conclude with Singer that all animals are equal. (shrink)

It is commonly asserted that “death is not a welfare issue” and this has been reflected in welfare legislation and policy in many countries. However, this creates a conflict for many who consider animal welfare to be an appropriate basis for decision-making in animal ethics but also consider that an animal’s death is ethically significant. To reconcile these viewpoints, this paper attempts to formulate an account of death as a welfare issue. Welfare issues are issues that refer to evaluations concerning (...) an animal’s interests. This includes evaluations that refer only to comparisons between the presence and absence of states, including positive states. This means that an animal’s death may be a welfare issue insofar as it leads to the exclusion of relevant positive states. This allows us to deny that death is necessarily not a welfare issue.

Animals have moral standing; that is, they have properties (including the ability to feel pain) that qualify them for the protections of morality. It follows from this that humans have moral obligations toward animals, and because rights are logically correlative to obligations, animals have rights.

: J. Baird Callicott's claim to have unified environmentalism and animal liberation should be rejected by holists and liberationists. By making relations of intimacy necessary for moral considerability, Callicott excludes from the moral community nonhuman animals unable to engage in intimate relations due to the circumstances of their confinement. By failing to afford moral protection to animals in factory farms and research laboratories, Callicott's biosocial moral theory falls short of meeting a basic moral demand of liberationists. Moreover, were Callicott to (...) include factory farm and research animals inside the moral community by affording them universal or non-communitarian rights, his theory would fall foul of environmentalists who seek to promote ecosystem stability and integrity via therapeutic hunting. If factory farm and research animals can have rights irrespective of their particular circumstances, then so can free- roaming animals from overabundant and exotic species. (shrink)

: Animal ethics has presented convincing arguments for the individual value of animals. Animals are not only valuable instrumentally or indirectly, but in themselves. Less has been written about interest conflicts between humans and other animals, and the use of animals in practice. The motive of this paper is to analyze different approaches to interest conflicts. It concentrates on six models, which are the rights model, the interest model, the mental complexity model, the special relations model, the multi-criteria model, and (...) the contextual model. Of these, the contextual model is the strongest, and carries clear consequences for the practical use of animals. (shrink)

Animal liberation ethics and environmental ethics have recently come of age. Concerning concrete moral rules considered by researchers in these areas there is much consensus. Highly general theories formulated to justify the rules are more problematic. However, the search for such theories may well be misguided.
