Towards a systematic evaluation of moral bioenhancement.

The ongoing debate about moral bioenhancement (MBE) has been exceptionally stimulating, but it is defined by extreme polarization and lack of consensus about any relevant aspect of MBE. This article reviews the discussion on MBE, showing that a lack of consensus about enhancements' desirable features and the constant development of the debate calls for a more rigorous ethical analysis. I identify a list of factors that may be of crucial importance for illuminating the matters of moral permissibility in the MBE debate and which could help us move beyond the current lack of consensus. More precisely, I propose three important theoretical and normative standards that MBE should satisfy if we wish to mitigate the concerns about its utter impermissibility. Systematically assessing MBE interventions across the presented categories should provide valuable conclusions about its theoretical soundness and feasibility, its compatibility with fundamental moral norms, and its compatibility with or facilitation of socio-political goals of equality and justice.

On the uneasy alliance between moral bioenhancement and utilitarianism.

Moral bioenhancement (MBE) is often associated with a consequentialist, especially utilitarian, framework, owing to its capacity to prevent great harm and motivate acts in accordance with basic moral principles such us universal impartial altruism or benevolence. However, it remains unclear whether we could de facto justify MBE on utilitarian grounds. This article examines whether there is a plausible utilitarian case for MBE and what the obstacles for justifying MBE on utilitarian grounds could be. More specifically, it explores the relationship between MBE and basic utilitarian principles, as well as its effects on utilitarian moral judgment. It seems that MBE could modify moral agents in ways that would accord with the main utilitarian demands and facilitate the adoption and realization of utilitarian prescriptions. Although MBE would, in principle, create preconditions for achieving utilitarian ends, I argue that there are certain limits to this claim. I identify and elaborate several ways in which MBE could undermine utilitarian moral judgment.

Is human enhancement intrinsically bad?

A pertinent concern in the human enhancement debate is that human enhancement technologies (HET) are intrinsically bad and, hence, morally impermissible. This article evaluates the related claims about the intrinsic badness of HET by looking into philosophical theories of intrinsic value. It investigates how well-established conceptions of intrinsic value map onto typical bioconservative arguments about HET's intrinsic badness. Three predominant variants of these arguments are explored and found wanting: (i) HET are intrinsically bad owing to their unnaturalness; (ii) the pursuit of HET reveals intrinsically bad character ("the desire for mastery"); and (iii) HET will necessarily undermine intrinsically valuable things (e.g., human dignity). My analysis shows that the debate on intrinsic value places serious constraints on claims about the intrinsic badness of HET. More specifically, the analysis shows that bioconservative arguments are, for the most part, inconsistent, misconceived, and overly speculative. Enhancement interventions cannot be bearers of intrinsic value on any of its plausible understandings, and, even if we could grant such a possibility, there are no compelling reasons to presume that the intrinsic value of HET would be necessarily negative. As a result, claims regarding their moral impermissibility are unwarranted.
