Nanotechnologies that have been linked to the possibility of enhancing cognitive capabilities of human beings might also be deployed to reduce or eliminate such capabilities in non-human vertebrate animals. A surprisingly large literature on the ethics of such disenhancement has been developed in response to the suggestion that it would be an ethically defensible response to animal suffering both in medical experimentation and in industrial livestock production. However, review of this literature illustrates the difficulty of formulating a coherent ethical debate. (...) Well structured arguments for disenhancement can be made on the basis of mainstream views on the basis of ethical obligations to animals, but these arguments have not been persuasive against the moral intuition that disenhancements are unethical. At the same time, attempts to ground these intuitions in a coherent philosophical doctrine have been plagued by logical fallacies and question begging assertions. As such, the debate over animal disenhancement forecasts an enduring conundrum with respect to the core question of transforming the nature of sentient beings, and this conundrum is logically independent of claims that relate either to the distinctive of human beings or to issues deriving from the emphasis on enhancement.

Though the vegetarian movement sparked by Peter Singer’s book Animal Liberation has achieved some success, there is more animal suffering caused today due to factory farming than there was when the book was originally written. In this paper, I argue that there may be a technological solution to the problem of animal suffering in intensive factory farming operations. In particular, I suggest that recent research indicates that we may be very close to, if not already at, the point where we (...) can genetically engineer factory-farmed livestock with a reduced or completely eliminated capacity to suffer. In as much as animal suffering is the principal concern that motivates the animal welfare movement, this development should be of central interest to its adherents. Moreover, I will argue that all people concerned with animal welfare should agree that we ought to replace the animals currently used in factory farming with animals whose ability to suffer is diminished if we are able to do so.

Bernard Rollin argues that it is permissible to change an animal's telos through genetic engineering, if it doesn't harm the animal's welfare. Recent attempts to undermine his argument rely either on the claim that diminishing certain capacities always harms an animal's welfare or on the claim that it always violates an animal's integrity. I argue that these fail. However, respect for animal dignity provides a defeasible reason not to engineer an animal in a way that inhibits the development of those (...) functions that a member of its species can normally perform, even if the modification would improve the animal's welfare.

It is widely assumed that disability is typically a bad thing for those who are disabled. Our purpose in this essay is to critique this view and defend a more nuanced picture of the relationship between disability and well-being. We first examine four interpretations of the above view and argue that it is false on each interpretation. We then ask whether disability is thereby a neutral trait. Our view is that most disabilities are neutral in one sense, though we cannot (...) make simple generalizations about disability's relationship to well-being in other important senses. After defending this view, we discuss its practical implications for selective abortion for disability, nondisabled people's interactions with disabled people, and the use of QALYs in health policy.

Suppose “chicken” eggs could be produced by quasi‐chickens—genetically engineered humps of living chicken‐flesh that do nothing but lay eggs. Would there be anything amiss with that? Animal ethicists invoke the notion of animal integrity in order to give intellectual content to the intuition that there would be. On inspection, ‘integrity’ isn't everything its proponents want it to be. Yet there's enough in it to make reasoned argument possible.

Disability is primarily a social phenomenon -- a way of being a minority, a way of facing social oppression, but not a way of being inherently or intrinsically worse off. This is how disability is understood in the Disability Rights and Disability Pride movements; but there is a massive disconnect with the way disability is typically viewed within analytic philosophy. The idea that disability is not inherently bad or sub-optimal is one that many philosophers treat with open skepticism, and sometimes (...) even with scorn. The goal of this book is to articulate and defend a version of the view of disability that is common in the Disability Rights movement. To be physically disabled is not to have a defective body, but simply to have a minority body. (shrink)

Drawing heavily on recent empirical research to update R.M. Hare's two-level utilitarianism and expand Hare's treatment of "intuitive level rules," Gary Varner considers in detail the theory's application to animals while arguing that Hare should have recognized a hierarchy of persons, near-persons, & the merely sentient.

This book is a philosophically sophisticated and scientifically well-informed discussion of the moral and social issues raised by genetically engineering animals, a powerful technology which has major implications for society. Unlike other books on this emotionally charged subject, the author attempts to inform, not inflame, the reader about the real problems society must address in order to manage this technology. Bernard Rollin is both a professor of philosophy, and physiology and biophysics, and writes from a uniquely well-informed perspective on this (...) topic. The style is non-technical and anecdotal and will ensure that the book can be used on a wide range of courses on bioethics, biotechnology, veterinary medicine and public policy. The book could also appeal to a general, non-academic reader with a serious interest in genetic engineering. (shrink)

This article seeks to engage with contemporary debates on the social and ethical dimensions of genetically modified (GM) animals. Dominant policy ethical approaches and frameworks are criticized for failing radically to accommodate some of the most important dimensions of concern. Drawing on primary empirical data emphasizing existing embodied relationships to animals, the article analyses how people express ethical concern over GM animals, including their sense of the continuities and discontinuities between GM animals and those determined by conventional selective breeding practices. (...) The findings suggest that GM animals are likely to become an issue of public controversy, especially in the animal testing domain, due to the ways in which they symbolize and give voice to underlying tensions between ‘moral’and ‘instrumental’approaches to animals.The article concludes that people reject GM animals as ‘going against nature’, and that such concerns reflect wider unease about science, about technological modernity, and about hubris.

Are disgusting or disrespectful actions judged to be moral violations, even when they are harmless? Stories about victimless yet offensive actions (such as cleaning one's toilet with a flag) were presented to Brazilian and U.S. adults and children of high and low socioeconomic status (N = 360). Results show that college students at elite universities judged these stories to be matters of social convention or of personal preference. Most other Ss, especially in Brazil, took a moralizing stance toward these actions. (...) For these latter Ss, moral judgments were better predicted by affective reactions than by appraisals of harmfulness. Results support the claims of cultural psychology (R.A. Shweder, 1991a) and suggest that cultural norms and culturally shaped emotions have a substantial impact on the domain of morality and the process of moral judgment. Suggestions are made for building cross-culturally valid models of moral judgment. (shrink)
