Abstract

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.
