Annotated bibliography on eugenics and philosophy.

A prominent objection to non-cognitive moral bio-enhancements is that they would compromise the recipient’s ‘freedom to fall’. I begin by discussing some ambiguities in this objection, before outlining an Aristotelian reading of it. I suggest that this reading may help to forestall Persson and Savulescu’s ‘God-Machine’ criticism; however, I suggest that the objection still faces the problem of explaining why the value of moral conformity is insufficient to outweigh the value of the freedom to fall itself. I also question whether (...) the objection is compatible with Neil Levy’s parity principle. Accordingly, I go on to consider an alternative relational freedom-based objection to NCMBEs that aims to explain the fundamental moral importance of the freedom that NCMBEs would violate. I argue that although this strategy might allow the critic of NCMBEs to bypass a powerful criticism of Harris’ objection, it also weakens the freedom-based objection’s compatibility with the parity principle.

Recent breakthroughs in stem cell differentiation and reprogramming suggest that functional human gametes could soon be created in vitro. While the ethical debate on the uses of in vitro generated gametes (IVG) was originally constrained by the fact that they could be derived only from embryonic stem cell lines, the advent of somatic cell reprogramming, with the possibility to easily derive human induced pluripotent stem cells from any individual, affords now a major leap in the feasibility of IVG derivation and (...) in the scope of their potential applications. In this paper we develop an ethical framework, rooted in recent scientific evidence, to support a robust experimental pipeline that could enable the first-in-human use of IVG. We then apply this framework to the following objectives: (1) a clarification of the genetic parenting options afforded by IVG, along with their ethical underpinnings; (2) a defence of the use of IVG to remedy infertility, broadening their scope to same-sex couples; (3) an assessment of the most far-reaching implications of IVG for multiplex parenting. These include, first, the liberation of parenting roles from the constraints of biological generations in vivo, allowing multiple individuals to engage in genetic parenting together, thus blurring the distinction between biological and social generations. Second, we discuss the conflation of IVG with sequencing technology and its implications for the possibility that prospective parents may choose among a hitherto unprecedented number of potential children. In view of these perspectives, we argue that, contrary to the exhausted paradigm according to which society lags behind science, IVG may represent instead a salient and most visible instance where biotechnological ingenuity could be used in pursuit of social experimentation.

This paper gives an introduction to the interdisciplinary special section. Against the historical and ethical background of reproductive technologies, it explores future scenarios of human reproduction and analyzes ways of mutual engagement between fictional and academic endeavors. The underlying idea is that we can make use of human reproduction scenarios in at least two ways: we can use them to critique technologies by imagining terrible consequences for humanity but also to defend positions that favor scientific and technological development.

Abstract:Research into the development of stem cell-derived (SCD) gametes in humans, otherwise known asin vitrogametogenesis (IVG), is largely motivated by reproductive aims. Especially, the goal of establishing genetic parenthood by means of SCD-gametes is considered an important aim. However, like other applications in the field of assisted reproduction, this technology evokes worries about the possibility of creating so-called ‘designer babies.’ In this paper, we investigate various ways in which SCD-gametes could be used to create such preference-matched offspring, and what this (...) would mean for the acceptability of IVG, if it is premised that it is morally problematic to ‘design’ offspring. We argue that IVG might facilitate the creation of preference-matched offspring, but conclude that this should not undermine the moral acceptability of IVG altogether—even if one concedes the premise that creating ‘designer babies’ is morally problematic. In the light of this, we also point at a possible inconsistency for a position that condemns the creation of ‘designer offspring,’ while accepting the various endeavors to have genetically related offspring.

The year 2015 has been a decisive year for the future of mitochondrial replacement therapy – at least in the Western world. Currently, the UK and the US governments are undergoing a process of ethical and scientific evaluation of the technique to decide whether to allow its implementation or not. MRT requires the fusion of the DNA of three parents into an embryo – and this creates a number of worries as to what this scientific innovation will lead to. These (...) worries might be well placed and worthy of consideration, but not on the grounds presented by some opponents. In this paper, we will analyse a recent European Union petition that urged the UK government to refrain from legalising MRT, stressing that other techniques, such as preimplantation genetic diagnosis, already have a more direct eugenic potential than MRT. Although the UK Parliament recently voted in favour of MRT, an analysis of the EU petition can nonetheless still contribute to understanding some of the key aspects of the debate. Our conclusion is that what seems to be really at stake, instead, is whether or not we are willing to reconceptualise our notion of parenthood as something not necessarily binominal and genetically related.

With the development of new procedures in the production of synthetic human gametes it has become important to re-examine the manner in which reproductive cells, taking part in the generation of children, can be understood. Though this can be attempted from many different perspectives, the present study will examine the possibility of considering gametes as representing the persons from whom they originated. From this perspective, it is possible to suggest that, in procreation, the entirety of each human sperm cell may (...) represent and reveal the man from whom it was produced and the entirety of each human egg cell may represent and reveal the woman from whom it was produced.The possible ethical consequences of using synthetic gametes for those who hold this perspective together with their understanding of relational identity will also be examined.
