Abstract

Can neuroscience tell us what is right and wrong? It is difficult to deny that there is an intimate connection between brain and behavior, and a special relationship between our brains and ourselves. In recent decades, neuroscientists and philosophers have discovered that they always return to the same questions: conscience, the self, perception, thought, feelings, will, intentionality, morality, etc. Functional neuroimaging does not show human thought “per se” but only correlates of certain functions involved. It is an indirect approach that generates important ethical, legal and social questions. Its growing popularity, the expectations generated and the emerging commercial, educational and legal applications have led to a surge of publications in strictly scientific journals and in others dedicated to areas such as ethics or law, although there is a notable lack of communication between them. In this article, we review what we currently know about the neurological basis of ethics from a philosophy of science perspective, defending the idea that there is no “ethics module” in the brain, if we understand correctly the meaning of ethics, an attractive but overused term.

Keywords: ethics, brain, neuroimaging, morality.
