Ethical problems resulting from brain research have given rise to a new discipline termed neuroethics, representing a new kind of knowledge capable of discovering the neural basis for universal ethics. The article (1) tries to evaluate the contributions of neuroethics to medical ethics and its suitability to outline the foundations of universal ethics, (2) critically analyses the process of founding this universal ethic. The potential benefits of applying neuroimaging, psy-chopharmacology and neurotechnology have to be carefully weighed against their potential harm. In view of these questions, an intensive dialogue between neuroscience and the humanities is more necessary than ever.
