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. (shrink)

Transhumanism at once embodies our most modern thinking and our biggest longstanding problems. Transhumanism aims to enhance human core capacities: health-span, lifespan, and cognition. The thesis answers the following ethical challenges arising from transhumanist aims. First, whether transhumanism can be an ethical endeavour if it relies on authoritarian intervention by governments and governing bodies to change, generate and enforce behaviour, or to influence and enforce the uptake of medical procedures. Second, the thesis answers the challenge that it is unethical deliberately (...) to encourage the uptake of and pursuit of medical transhumanism given the extent of accessibility and distributive issues that remain unresolved in existing medicine. Finally, the thesis addresses a particular mental health crisis that is often predicted for transhuman beings, namely loss of meaning from loss of death and vulnerability, resulting in widespread loss of social cohesion. The thesis argues that the right solution to the first two problems is a libertarian paternalist approach, viz. nudging, and that this approach will also neutralise the risk of widespread and inevitable boredom or alienation that might otherwise result from the widespread introduction of human enhancement if people are nudged to engage more and more reflectively in their enhancement choices. Additionally, lifestyle issues like obesity, heart disease, cancers, and inaccessibility of vaccines and birth control pose unresolved problems for existing general medicine, killing millions every year worldwide. As a result, another serious challenge for enhancement medicine, which I propose would be addressed by the nudge approach, is to justify its place in the professional domain of medicine. (shrink)
