I discuss the argument of Persson and Savulescu that moral enhancement ought to accompany cognitive enhancement, as well as briefly addressing critiques of this argument, notably by John Harris. I argue that Harris, who believes that cognitive enhancement is largely sufficient for making us behave more morally, might be disposing too easily of the great quandary of our moral existence: the gap between what we do and what we believe is morally right to do. In that regard, Persson and Savulescu's (...) position has the potential to offer more. However, I question Persson and Savulescu's proposal of compulsory moral enhancement , proposing the alternative of voluntary moral enhancement. (shrink)

Some argue that humans should enhance their moral capacities by adopting institutions that facilitate morally good motives and behaviour. I have defended a parallel claim: that we could permissibly use biomedical technologies to enhance our moral capacities, for example by attenuating certain counter-moral emotions. John Harris has recently responded to my argument by raising three concerns about the direct modulation of emotions as a means to moral enhancement. He argues that such means will be relatively ineffective in bringing about moral (...) improvements, that direct modulation of emotions would invariably come at an unacceptable cost to our freedom, and that we might end up modulating emotions in ways that actually lead to moral decline. In this article I outline some counter-intuitive potential implications of Harris' claims. I then respond individually to his three concerns, arguing that they license only the very weak conclusion that moral enhancement via direct emotion modulation is sometimes impermissible. However I acknowledge that his third concern might, with further argument, be developed into a more troubling objection to such enhancements. (shrink)

Selective serotonin reuptake inhibitors (SSRIs) have gained a degree of prominence across recent moral enhancement literature as a possible intervention for dealing with antisocial and aggressive impulses. This is due to serotonin's purported capacity to modulate persons’ averseness to harm. The aim of this article is to argue that the use of SSRIs is not something worth getting particularly excited about as a practicable intervention for moral enhancement purposes, and that the generally uncritical enthusiasm over serotonin's potential as a moral (...) enhancer is a consequence of the paucity of viable options for envisaging practicable moral enhancement interventions. While there are many conceptual issues raised by the idea of moral enhancement generally, and by the idea of serotonin as a morally affective agent, the aim here is to look at practical concerns. It is argued that SSRIs do not, nor cannot in the reasonably foreseeable future, be made to work as a reliably safe or reliably effective means for moral enhancement, even within the very limited remit of treating “reactive” aggression. SSRIs might be effective as a limited and partial mental health intervention (even this is questionable), but not as a generally effective moral enhancement technology. (shrink)

The normative significance of the distinction between therapy and enhancement has come under sustained philosophical attack in recent discussions of the ethics of shaping future persons by means of preimplantation genetic diagnosis and other advanced genetic technologies. In this paper, I argue that giving up the idea that the answer to the question as to whether a condition is “normal” should play a crucial role in assessing the ethics of genetic interventions has unrecognized and strongly counterintuitive implications when it comes (...) to selecting what sort of children should be brought into the world. According to standard philosophical accounts of the factors one should take into account when making such .. (shrink)
