 For philosophers, Wundt is worth studying for two reasons. First, the arguments he made more than a century ago for the legitimacy of a non-reductionist account of consciousness offer both challenges and resources to contemporary psychology and philosophy of mind alike. Should those arguments be found lacking, there remains a second, perhaps more important reason to read him: not understanding Wundt is to tolerate a lacuna at a crucial nexus of the recent history of philosophy. Not only was he a powerful influence (albeit mostly by repulsion) upon the founders of Pragmatism, Phenomenology, and neo-Kantianism, it was also Wundt and his pioneering students who developed the empirical methodologies that first granted psychology a disciplinary identity distinct from philosophy. It is these philosophically germane aspects of his thought that this article describes.
