RESUMEN
Moral bioenhancement presents the possibility of enhancing morally desirable emotions and dispositions. While some scholars have proposed that moral bioenhancement can produce virtue, we argue that within a virtue ethics framework moral bioenhancement cannot reliably produce virtue. Moreover, on a virtue ethics framework, the pursuit of moral bioenhancement carries moral risks. To make this argument, we consider three aspects of virtue-its motivational, rational, and behavioral components. In order to be virtuous, we argue, a person must (i) take pleasure in doing the right thing and have the correct motivational attitudes; (ii) reason correctly about what is called for in a particular ethical dilemma; and (iii) intentionally and continuously practice and cultivate virtues. These dimensions of morality-in short: precisely those emphasized in a virtue ethics framework-cannot be consistently or reliably met using existing moral bioenhancement technology.
