Neuroethics: what else is new?

Bioethics has changed considerably over the years, the increasing diversity of topics of bioethical interest having led to specialisation if not fragmentation. In this context the term “neuroethics" emerged, and it soon became clear that it could be understood in two ways. The “ethics of neuroscience” assesses the ethical and philosophical implications of research in neuroscience and of the application of these discoveries, especially as regards enhancement of “normal” human faculties or new challenges to privacy. The “neuroscience of ethics” basically turns the tables on ethics: it is ethical reasoning itself that becomes the object of neuroscience research. This provides a “behind the scenes” glance into moral reasoning, challenging aspects of moral philoso-phy and of the conventional philosophical interpretation of human action and free will. On the more practical side, neuroethics increases the level of awareness of the relatively neglected area of diseases of the brain-mind.
