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)

Our present moral traits are unable to provide the level of large-scale co-operation necessary to deal with risks such as nuclear proliferation, drastic climate change and pandemics. In order to survive in an environment with powerful and easily available technologies, some authors claim that we need to improve our moral traits with moral enhancement. But this is prone to produce paradoxical effects, be self-reinforcing and harm personal identity. The risks of moral enhancement require the use of a safety framework; such (...) a framework should guarantee practical robustness to moral uncertainty, empirical adequacy, correct balance between dispositions, preservation of identity, and be sensitive to practical considerations such as emergent social effects. A virtue theory can meet all these desiderata. Possible frameworks incorporate them to variable degrees. The social value orientations framework is one of the most promising candidates. (shrink)

I will argue that deep moral enhancement is relatively prone to unexpected consequences. I first argue that even an apparently straightforward example of moral enhancement such as increasing human co-operation could plausibly lead to unexpected harmful effects. Secondly, I generalise the example and argue that technological intervention on individual moral traits will often lead to paradoxical effects on the group level. Thirdly, I contend that insofar as deep moral enhancement targets higher-order desires, it is prone to be self-reinforcing and irreversible. (...) Fourthly, I argue that the complex causal history of moral traits, with its relatively high frequency of contingencies, indicates their fragility. Finally, I conclude that attempts at deep moral enhancement pose greater risks than other enhancement technologies. For example, one of the major problems that moral enhancement is hoped to address is lack of co-operation between groups. If humanity developed and distributed a drug that dramatically increased co-operation between individuals, we would likely see a paradoxical decrease in co-operation between groups and a self-reinforcing increase in the disposition to engage in further modifications – both of which are potential problems.

This article brings together two debates in bioethics more substantively than has been the case until now. One is the methodological debate over "principlism," i.e., the theoretical framework for analyzing and solving ethical problems proposed by Beauchamp and Childress in Principles of Biomedical Ethics. The other is the normative debate about reproductive ethics, i.e., procreative rights and obligations in a time of pervasive opportunities for making detailed choices about the properties and capacities of future people. The obvious point of bringing (...) the debates together is to show how they can illuminate each other in fruitful ways consistent with the method of reflective equilibrium endorsed in PBE. Furthermore, discussions of reproductive ethics is almost absent in PBE, making it an interesting "test case" on how principlist theory can have an impact on and be affected by confrontations with new practices and considerations in biomedicine. Reproductive ethics is especially interesting due to the so-called non-identity considerations, which pose a challenge to common morality views on harm to and respect for persons. My focus is mainly on some methodological points about the import of concrete normative discussions for formulating basic normative principles. However, I unfold a number of substantial points in order to demonstrate this. It is my impression that most writers on principlism underestimate the effect of engaging with concrete problems. Specifically, I conclude that reflecting on procreative obligations provides strong reasons for specifying the basic principles in ways that uncover new dimensions of them and not just new applications. _Key words: _principlism, reproductive ethics, non-identity problem, nonmaleficence, respect for persons.
