The emerging field of neuroethics raises a number of questions for Christian theology and ethics. For example: what should Christians make of purported neurobiological explanations of religion and morality? Do the neurosciences require a re-appraisal of our notions of freewill and moral responsibility? How might we morally evaluate clinical interventions on the brain? In this lecture, Neil Messer will propose an approach to questions such as these, focusing in particular on the context of a Reformed Christian theological tradition.
