In this provocative work, a distinguished philosopher and a leading neuroscientist outline the conceptual problems at the heart of cognitive neuroscience. Writing from a scientifically and philosophically informed perspective, the authors provide a critical overview of the conceptual difficulties encountered in many current neuroscientific and psychological theories, including those of Blakemore, Crick, Damasio, Edelman, Gazzaniga, Kandel, Kosslyn, LeDoux, Penrose and Weiskrantz. They propose that conceptual confusions about how the brain relates to the mind affect the intelligibility of research carried out by neuroscientists, in terms of the questions they choose to address, the description and interpretation of results and the conclusions they draw. The book forms both a critique of the practice of cognitive neuroscience and a conceptual handbook for students and researchers.
