Abstract

In Our Knowledge of the Internal World, Robert Stalnaker presents a sophisticated new defense of a radically externalist and contextualist approach to mental content. Stalnaker holds that unstructured propositions—sets of possible worlds—can provide a complete account of mental content, including Fregean cognitive significance phenomena. So there is no theoretical job for concepts to fulfill. Stalnaker sees concepts as ‘creatures of darkness’ that encourage theoretical confusion. Concepts are a vestige of the mistaken internalist picture of the mind: internal states that are supposed to ensure transparent access to the objects, kinds, or properties our thoughts represent. I argue there are better reasons for positing concepts—reasons that are independent of the internalist project.
