This is the second paper in a three-part series on the state of the enhancement debate. We report current trends and give an overview of established positions in the field of neuroenhancement. Unlike a number of articles on the bioethics of enhancement, we try to highlight connections between the contemporary debate and established positions in philosophical ethics. This specific perspective inspired the breakdown of our three-part series into consequentialist, deontological and virtue-ethical arguments.

Recent developments in genomic science hold out the tantalizing prospect of soon being able to treat and prevent a wide variety of medical conditions through gene therapy. In time, it may be possible to use similar techniques not simply to combat disease but also to enhance, or improve on, normal human functioning.

In this article, I present what I believe to be the core of Jürgen Habermas’s views on the morality, ethics, and regulation of emerging genetic and reproductive technologies in his bookThe Future of Human Nature.

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)
