In this paper, I respond to recent criticisms, by Paula Casal, of my arguments about the implications of John Harris and Julian Savulescu's influential arguments for human enhancement for sex selection. I argue that, despite her protestations, her paper relies upon the idea that parents have a moral obligation to have children that will serve the interests of the nation. Casal’s use of dubious claims about inherent psychological differences between men and women to make her hypothetical case for moral enhancement (...) and her troubling references to “evolved humans” only exacerbate the political dangers involved in the argument for human enhancement.

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.

In this paper, I respond to criticisms by John Harris, contained in a commentary on my article “Harris, harmed states, and sexed bodies”, which appeared in the Journal of Medical Ethics, volume 37, number 5. I argue that Harris's response to my criticisms exposes the strong eugenic tendencies in his own thought, when he suggests that the reproductive obligations of parents should be determined with reference to a claim about what would enhance ‘society’ or ‘the species’.

The objective of this study is to compare the quantity of citations that retracted and nonretracted articles received in engineering based on articles indexed in the Web of Science database and published between 1945 and 2015. For data analysis, the Statistical Package for the Social Sciences was used along with the Kolmogorov–Smirnov, Mann–Whitney, Tukey–Kramer tests and descriptive statistics. The data set included 238 retracted and 236 nonretracted articles, with the retracted articles cited 2,348 times and nonretracted articles cited 2,957 times. (...) The results highlight that retraction does not end citation, thus threatening scientific credibility. (shrink)

Robert Sparrow argues that because of women's longer life expectancy philosophers who advocate the genetic modification of human beings to enhance welfare rather than merely supply therapy are committed to favouring the selection of only female embryos, an implication he deems sufficiently implausible to discredit their position. If Sparrow's argument succeeds, then philosophers who advocate biomedical moral enhancement also seem vulnerable to a similar charge because of men's greater propensity for various forms of harmful wrongdoing. This paper argues there are (...) various flaws in Sparrow's argument that render it unsuccessful. The paper also examines whether dimorphism reduction is a more desirable outcome than male elimination, thereby further illustrating the difficulties besetting the distinction between therapy and enhancement.
