Research that involves the creation of animals with human-derived parts opens the door to potentially valuable scientific and therapeutic advances, yet invokes unsettling moral questions. Critics and champions alike stand to gain from clear identification and careful consideration of the strongest ethical objections to this research. A prevailing objection argues that crossing the human/nonhuman species boundary introduces inexorable moral confusion (IMC) that warrants a restriction to this research on precautionary grounds. Though this objection may capture the intuitions of many who (...) find this research unsettling, it relies on mistaken views of both biology and moral standing, ultimately distorting the morally relevant facts. We critically examine IMC, identify mistaken essentialist assumptions, and reframe ethical concerns. The upshot is a stronger line of objection that encourages a more inclusive and productive ethical discourse. (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)

For two decades, egalitarian analytical philosophers have sought to identify the metric to be employed in order to ascertain whether any distribution is equal or not. This essay provides a review of the seminal contributions to this debate by Amartya Sen, Ronald Dworkin, Richard Arneson and G.A. Cohen.

The philosophical literature on the moral status of nonhuman animals, which is bounteous, diverse, and sophisticated, contains a glaring omission. There is little discussion of human responsibilities to companion animals, such as dogs and cats. The assumption seems to be that animals are an undifferentiated mass – that whatever responsibilities one has to any animal are had to all animals. It is significant that we do not think this way about humans. Most of us (all but extreme impartialists) acknowledge the (...) existence of special responsibilities to humans. We believe, for instance, that our children, friends, and compatriots have special claims on our attention, time, energy, and resources. This is not at all incompatible (although it is sometimes thought to be) with the view that we have obligations to strangers. My aim in this essay is to fill the lacuna in the literature. I argue that the act of taking an animal into one''s life or home, through purchase, gift, or adoption, generates responsibilities to it, the main one being to provide for its needs, which, in the case of dogs (for example), are many and varied. Since this thesis is shrouded in misconception, I devote part of the essay to clarifying it. I then diagnose its philosophical neglect, which stems from both practical concerns and theoretical commitments. I argue that the practical concerns are groundless and that the theoretical commitments do not have the implications they are thought to have. (shrink)

abstract I distinguish between four arguments commonly used to justify experimentation on animals (I). After delineating the autonomy of the question of experiments from other topics within animal ethics (II), I examine and reject each of these justifications (III–VI). I then explore two arguments according to which animal‐dependent experimentation should continue even if it is immoral (VII). I close with the way in which liberationists’ strategic considerations modify the moral conclusions of my analysis.

Precision livestock farming promises to allow modern, large-scale farms to replicate, at scale, caring farmers who know their animals. PLF refers to a suite of technologies, some only speculative. The goal is to use networked devices to continuously monitor individual animals on large farms, to compare this information to expected norms, and to use algorithms to manage individual animals automatically. Supporters say this could not only create an artificial version of the partially mythologized image of the good steward caring for (...) his or her animals, but to also improve on it. As one paper in favor of PLF has said, “We can not only replace the farmer’s ‘eyes and ears’ to each individual animal as in the past, but several other variables will soon be measurable in practice” Livestock production and society, Wageningen Academic Publishers, Wageningen, pp 287–292, 2006). Yet these methods of monitoring and control raise a host of ethical issues, including alienation of laborers, further consolidation of farms, and further cover for meat consumption. In this paper, I will address these ethical issues, and suggest a different, under-examined concern: namely, that though PLF may indeed improve the lives of livestock, and the sustainability of livestock operations, it is possible that it will do so at the cost of a loss of identity and relationships for farmers, as well as for the animals in their charge.

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)

The topic of cruelty features regularly in discussions concerning animals’ moral status. Further, condemnation of cruelty to animals is virtually unanimous. As Regan points out, ‘[i]t would be difficult to find anyone who is in favour of cruelty.’ What is to count as cruelty is therefore important. My aim here is to gain a clearer understanding of one aspect of our moral landscape: cruelty to animals. I will start by analyzing the concept of cruelty in section II. In section III (...) I will examine some implications of this analysis. I will present two arguments for why we should reassess whether modern farming practices are cruel. First, farming practices have changed and our understanding of the concept of cruelty needs to change with them. Second, our application of the concept of cruelty is inconsistent: we would consider many routine practices involving farm animals to be cruel if they involved pets. This inconsistency presents a dilemma: either extending farming practices to pets would not be cruel, or continuing our current farming practices is cruel. In section IV I consider some objections.

: The treatment of animals and the Holocaust have been compared many times before, but never has a thoroughly detailed comparison been offered. A thirty-nine-point comparison can be constructed, whether or not one believes that animals are oppressed. The question of whether or not the comparison ought to be expressed merely brings into question whether animal liberationists have liberal-democratic rights to express themselves, which they surely do. Four objections are considered: Is the comparison offensive? Does the comparison trivialize what happened (...) to the victims of the Nazis, overlook important differences, or ignore supposed affinities between animal liberationists and Nazis? These four lines of attack are shown to fail. The comparison stands to help us to reflect on the significance of how animals are treated in contemporary times. (shrink)

We distinguish two conceptions of confinement – the agential conception and the comparative conception – and show that the former is intimately related to use in a way that the latter is not. Specifically, in certain conditions, agential confinement constitutes use and creates a special relationship that makes neglect or abuse especially egregious. This allows us to develop and defend an account of one important way in which agential confinement can be morally wrong. We then discuss some of the account’s (...) practical implications, including its usefulness for decision-making in real-world contexts in which animals are confined. (shrink)

Philosophers have taken some salutary exercise in recent years—notably in this journal—on the question of the rights of non-human animals and the obligations of human to non-human individuals and species. In so contentious an area there has been striking unanimity on two aspects. One of these is that, irrespective of the merits of the arguments on specific issues, this is a matter which is bound to affect the conduct of our lives. The other is that, other things being equal, it (...) is prima facie wrong to be cruel to animals. (shrink)

I bring several ecofeminist critiques of deep ecology to bear on mainstream animal rights theories, especially on the rights and utilitarian treatments of the animal research issue. Throughout, I show how animal rights issues are feminist issues and clarify the relationship between ecofeminism and animal rights.

Liberalism welcomes diversity in substantive ideas of the good but not in the process whereby these ideas are formed. Ideas of the good acquire weight on the presumption that each is a person's own, formed independently. But people differ in their capacities to conceptualize. Some, appropriately characterized as cerebral, are proficient in and profoundly involved with conceptualizing. Others, labeled cognitively disabled, range from individuals with mild limitations to those so unable to express themselves that we cannot be sure whether their (...) behavior is mediated by concepts at all. Constricted cognitive capacities have been thought to prevent participation in the prescribed process for forming personalized ideas of the good. So liberal theory, when formulating principles and practices of justice, often disregards cognitively disabled peoples' perspectives. We put aside metaphysically driven notions about personhood and show how interpersonal processes of “prosthetic” thinking (different from surrogacy) can satisfy liberalism's standards, positioning cognitively disabled individuals as fully participating subjects of justice.

Human–nonhuman chimeras have been the focus of ethical controversies for more than a decade, yet some related issues remain unaddressed. For example, little has been said about the relationship between the origin of transferred cells and the morally relevant capacities to which they may give rise. Consider, for example, a developing mouse fetus that receives a brain stem cell transplant from a human and another that receives a brain stem cell transplant from a dolphin. If both chimeras acquire morally relevant (...) capacities as a result of transplantation, and if those capacities are indistinguishable, should the difference in cell origin matter to how we classify these creatures? I argue that if morally relevant capacities are easy to detect, cell origin is irrelevant to how the chimera ought to be treated. However, if such capacities are hard to detect, cell origin should play a role in considerations about how to treat the chimera. (shrink)

I characterize the main approaches to the moral consideration of children developed in the light of the argument from 'marginal' cases, and develop a more adequate strategy that provides guidance about the moral responsibilities adults have towards children. The first approach discounts the significance of children's potential and makes obligations to all children indirect, dependent upon interests others may have in children being treated well. The next approaches agree that the potential of children is morally considerable, but disagree as to (...) whether and why children with intellectual disabilities are morally considerable. These approaches explore the moral significance of intellectual capacities, species membership, the capacity for welfare, and the interests of others. I argue that relationships characterized by reciprocity of care are morally valuable, that both the potential to be in such relationships and the actuality of being in them are morally valuable, and that many children with significant intellectual disabilities have this potential.

What we could call ‘relational non-interventionism’ holds that we have no general obligation to alleviate animal suffering, and that we do not typically have special obligations to alleviate wild animals’ suffering. Therefore, we do not usually have a duty to intervene in nature to alleviate wild animal suffering. However, there are a range of relationships that we may have with wild animals that do generate special obligations to aid—and the consequences of these obligations can be surprising. In this paper, it (...) is argued that we have special obligations to those animals we have historically welcomed or encouraged into our spaces. This includes many wild animals. One of the consequences of this is that we may sometimes possess obligations to actively prevent rewilding—or even to dewild—for the sake of welcomed animals who thrive in human-controlled spaces.
