Disability activists influenced by queer theory and advocates of “human enhancement” have each disputed the idea that what is “normal” is normatively significant, which currently plays a key role in the regulation of pre-implantation genetic diagnosis (PGD). Previously, I have argued that the only way to avoid the implication that parents have strong reasons to select children of one sex (most plausibly, female) over the other is to affirm the moral significance of sexually dimorphic human biological norms. After outlining the (...) logic that generates this conclusion, I investigate the extent to which it might also facilitate an alternative, progressive, opening up of the notion of the normal and of the criteria against which we should evaluate the relative merits of different forms of embodiment. This paper therefore investigates the implications of ideas derived from queer theory for the future of PGD and of PGD for the future of queerness. (shrink)

The idea that a world in which everyone was born “perfect” would be a world in which something valuable was missing often comes up in debates about the ethics of technologies of prenatal testing and preimplantation genetic diagnosis . This thought plays an important role in the “disability critique” of prenatal testing. However, the idea that human genetic variation is an important good with significant benefits for society at large is also embraced by a wide range of figures writing in (...) the bioethics literature, including some who are notoriously hostile to the idea that we should not select against disability. By developing a number of thought experiments wherein we are to contemplate increasing genetic diversity from a lower baseline in order to secure this value, I argue that this powerful intuition is more problematic than is generally recognized, especially where the price of diversity is the well-being of particular individuals.

This article discusses the ethics of the use of preimplantation genetic diagnosis to prevent the birth of children with intersex conditions/disorders of sex development , such as congenital adrenal hyperplasia and androgen insensitivity syndrome . While pediatric surgeries performed on children with ambiguous genitalia have been the topic of intense bioethical controversy, there has been almost no discussion to date of the ethics of the use of PGD to reduce the prevalence of these conditions. I suggest that PGD for those (...) conditions that involve serious medical risks for those born with them is morally permissible and that PGD for other “cosmetic” variations in sexual anatomy is more defensible than might first appear. However, importantly, the arguments that establish the latter claim have radical and disturbing implications for our attitude toward diversity more generally. (shrink)

‘Liberal eugenics’ has emerged as the most popular position amongst philosophers writing in the contemporary debate about the ethics of human enhancement. This position has been most clearly articulated by Nicholas Agar, who argues that the ‘new’ liberal eugenics can avoid the repugnant consequences associated with eugenics in the past. Agar suggests that parents should be free to make only those interventions into the genetics of their children that will benefit them no matter what way of life they grow up (...) to endorse. I argue that Agar's attempt to distinguish the new from the old eugenics fails. Once we start to consciously determine the genetics of future persons, we will not be able to avoid controversial assumptions about the relative worth of different life plans. Liberal eugenicists therefore confront the horns of a dilemma. Whichever way they try to resolve it, the consequences of widespread use of technologies of genetic selection are likely to look more like the old eugenics than defenders of the new eugenics have acknowledged.

Eugenics is often referred to in debates on the ethics of reproductive technologies and practices, in relation to the creation of moral boundaries between acceptable and unacceptable technologies, and acceptable and unacceptable uses of these technologies. Historians have argued that twentieth century eugenics cannot be reduced to a uniform set of practices, and that no simple lessons can be drawn from this complex history. Some authors stress the similarities between past eugenics and present reproductive technologies and practices (what I define (...) throughout the paper as ‘the continuity view’) in order to condemn the latter. Others focus on the differences between past and present practices (what I define throughout the paper as ‘the discontinuity view’) in order to defend contemporary reproductive technologies. In this paper, I explore the meanings of the word ‘eugenics’ and the relationship between its past and present uses in terms of contemporary debates on reproductive technologies and practices. I argue that moral disagreement about present technologies originate in divergent views of condemnable and justifiable features of the past. (shrink)

This paper explores the ethics of introducing genome-editing technologies as a new reproductive option. In particular, it focuses on whether genome editing can be considered a morally valuable alternative to preimplantation genetic diagnosis. Two arguments against the use of genome editing in reproduction are analysed, namely safety concerns and germline modification. These arguments are then contrasted with arguments in favour of genome editing, in particular with the argument of the child’s welfare and the argument of parental reproductive autonomy. In addition (...) to these two arguments, genome editing could be considered as a worthy alternative to PGD as it may not be subjected to some of the moral critiques moved against this technology. Even if these arguments offer sound reasons in favour of introducing genome editing as a new reproductive option, I conclude that these benefits should be balanced against other considerations. More specifically, I maintain that concerns regarding the equality of access to assisted reproduction and the allocation of scarce resources should be addressed prior to the adoption of genome editing as a new reproductive option.

The use of genetic technologies within the equine industries has become increasingly common since the horse genome was published in 2009 (Wade et al. 2009). Testing for genes coding for disease in...

This paper uses the fictional case of the ‘Babel fish’ to explore and illustrate the issues involved in the controversy about the use of cochlear implants in prelinguistically deaf children. Analysis of this controversy suggests that the development of genetic tests for deafness poses a serious threat to the continued flourishing of Deaf culture. I argue that the relationships between Deaf and hearing cultures that are revealed and constructed in debates about genetic testing are themselves deserving of ethical evaluation. Making (...) good policy about genetic testing for deafness will require addressing questions in political philosophy and anthropology about the value of culture and also thinking hard about what sorts of experiences and achievements make a human life worthwhile.
