Recent debate among bioethicists concerns the potential to enhance human beings’ physical or cognitive capacities by means of genetic, pharmacological, cybernetic, or surgical interventions. Between “transhumanists,” who argue for unreserved enhancement of human capabilities, and “bioconservatives,” who warn against any non-therapeutic manipulation of humanity’s natural condition, lie those who support limited forms of enhancement for the sake of individual and collective human flourishing. Many scholars representing these views also share a concern over the status and interests of human beings with (...) various types of cognitive and physical disabilities, some of which may be ameliorable by enhancement interventions. The question addressed in this paper is whether valuing the enhancement of human capabilities may be reconciled with valuing the existence and phenomenological experiences of human beings with various disabilities. Can we value enhanced capabilities without disvaluing those whose capabilities fall below a defined threshold of “normal function”? Furthermore, if certain forms of disability, particularly cognitive disabilities, negatively impact one’s flourishing, could the enhancement of one’s cognitive capacities through biotechnological means enhance one’s flourishing.

Some bioethicists have argued that moral bioenhancement, complementing traditional means of enhancing individuals’ moral dispositions, is essential if we are to survive as a species. Traditional means of moral enhancement have historically included civil legislation, socially recognized moral exemplars, religious teachings and disciplines, and familial upbringing. I explore the necessity and feasibility of pursuing methods of moral bioenhancement as a complement to such traditional means, grounding my analysis within a virtue-theoretic framework. Specifically, I focus on the essential intellectual virtue for (...) proper moral reasoning, prudence, and whether proposed methods of moral bioenhancement could facilitate the cultivation of this virtue within the psyches of moral agents. I conclude that certain means of bioenhancement may serve to augment the ability to reason prudentially and assist moral agents to align their wills with their higher-order rational desires, though such means require those higher-order desires to already have been formulated independently.
