Neuroscience and the Future of Personhood and Responsibility

This is a chapter in a book, Constitution 3.0: Freedom and Technological Change, edited by Jeffrey Rosen and Benjamin Wittes and published by Brookings. It considers whether likely advances in neuroscience will fundamentally alter our conceptions of human agency, of what it means to be a person, and of responsibility for action. I argue that neuroscience poses no such radical threat now and in the immediate future and it is unlikely ever to pose such a threat unless it or other sciences decisively resolve the mind-body problem. I suggest that until that happens, neuroscience might contribute to the reform of doctrines that do not accurately reflect truths about human behavior, to the resolution of individual cases, and to the efficient operation of various legal practices. If the power to predict and prevent dangerous behavior becomes sufficiently advanced, however, traditional notions of responsibility and guilt might simply become irrelevant
