How should ethics help decide the morality of enhancing morality? The idea of morally enhancing the human brain quickly emerged when the promise of cognitive enhancement in general began to seem realizable. However, on reflection, achieving moral enhancement must be limited by the practical challenges to any sort of cognitive modification, along with obstacles particular to morality’s bases in social cognition. The objectivity offered by the brain sciences cannot ensure the technological achievement of moral bioenhancement for humanity-wide application. Additionally, any (...) limited moral enhancement will not easily fulfil ethical expectations. Three hypothetical scenarios involving putative moral enhancement help illustrate why. Philosophical concerns about the “Does-Must Dichotomy” and the “Factor-Cause Plurality,” as I label them, forbid easy leaps from views about morality on to conclusions about ways to enhance morality, and then further on to ethically justifying those enhancements. A modest and realistic approach to moral enhancement emerges from exploring these issues. (shrink)

To gain insight into the reasons that the public may have for endorsing or eschewing pharmacological moral enhancement for themselves or for others, we used empirical tools to explore public attitudes towards these issues. Participants from the United States were recruited via Amazon’s Mechanical Turk and were randomly assigned to read one of several contrastive vignettes in which a 13-year-old child is described as bullying another student in school and then is offered an empathy-enhancing program. The empathy-enhancing program is described (...) as either involving taking a pill or playing a video game on a daily basis for four weeks. In addition, participants were asked to imagine either their own child bullying another student at school, or their own child being bullied by another student. This resulted in a 2 × 2 between-subjects design. In an escalating series of morally challenging questions, we asked participants to rate their overall support for the program; whether they would support requiring participation; whether they would support requiring participation of children who are at higher risk to become bullies in the future; whether they would support requiring participation of all children or even the entire population; and whether they would be willing to participate in the program themselves. We found that people were significantly more troubled by pharmacological as opposed to non-pharmacological moral enhancement interventions. The results indicate that members of the public for the greater part oppose pharmacological moral bioenhancement, yet are open to non-biomedical means to attain moral enhancement. [248 words].

This essay addresses two aspects of Persson and Savulescu's case for moral enhancement: 1) the precise technological nature of ultimate harm, particularly as it applies to the ecological crisis, and 2) what is at stake in the solution they propose. My claim is that Persson and Savulescu's treatment of both issues is inadequate: the ecological crisis is a more complex phenomenon than they suppose, and more is at stake in moral enhancement than they claim. To make my case I draw (...) on the work of Hans Jonas, who presciently and insightfully dealt with related questions. Jonas’ philosophy unites bioethical, technological, and environmental concerns and so offers a useful contrast to Persson and Savulescu's proposal. If my analysis is correct then we have both practical and principled reasons to be sceptical about the prospect of moral bioenhancement, which I assume, for the sake of argument, to be feasible.1.

The controversy over moral bioenhancement has fallen into a stalemate between advocates and critics. We wish to overcome this stalemate by addressing some of the key challenges any moral enhancement project has to meet. In particular, we shall argue that current proposals are unpersuasive as they, first, fail to diagnose the often complex causes of contemporary moral maladies and, second, are premised on methodological individualism. Focusing on brains and minds neglects social and environmental factors. Solving the mega-problems of today very (...) likely requires more than transforming individual brains, it requires structural and higher-level changes. By itself, moral bioenhancement is thus insufficient for solving these problems. Moreover, we outline some of the yet unresolved problems of legitimacy a mandatory state-run bioenhancement project faces and show why they cannot be defused through analogies with moral education. Finally, normatively less worrisome means of enhancing morality, such as psychotherapies affording self-exploration, are already available. Moral bioenhancement may thus not even be necessary for solving today’s mega problems. The overemphasis on speculative future technological fixes may cloud the view on possibilities to tackle pressing problems instantly. (shrink)
