Abstract

Do we need neuroethics? This provocative question, posed almost 20 years after a series of landmark neuroethics conferences in North America (Marcus 2002; Canadian Institutes of Health Research 2002), can’t be answered briefly. We can, however, consider some of the most important arguments in favor of neuroethics. First, neuroethics may appear to be needed because neuroscience offers a new lens on human morality. This is an argument made by neuroscientists Michael Gazzaniga (Gazzaniga 2005) and (to some extent) Jean-Pierre Changeux (Changeux & Ricoeur 2000; Changeux 1981)— though the latter does not use the term “neuroethics” explicitly. But is neuroscience really a unique or superior source of information about morality? Second, it may seem that neuroethics is needed to address the daunting ethical problems that are raised specifically by advances in neuroscience, including new technologies. But here again, there are reasons for nurturing healthy skepticism.
