Abstract

The possibility of morally enhancing the behavior of individuals by means of drugs and genetic engineering has been the object of intense philosophical discussion over the last few years. However; although moral enhancement may turn out to be useful to promote cooperation in some areas of human interaction; it will not promote cooperation in the domain of international relations in those areas that are critical to state security. Unlike some moral enhancement theorists; I argue that; because of the structure of the system of states; moral enhancement cannot be used to avert such major threats to humankind as terrorism and nuclear conflict. My analysis of the political implications of moral enhancement is pursued through a critical discussion of two different versions of political realism; namely human nature realism and structural realism. I conclude that; as far as major threats to the survival of humankind are concerned; moral enhancement can at most be used as a means to change the present structure of the system of states.
