Philosophers of mind tend to hold one of two broad views about mental representation: they are either robustly realist about mental representations, taking them to have determinate, objective content independent of attributors’ explanatory interests and goals, or they embrace some form of anti-realism, holding that mental representations are at best useful fictions. It is becoming increasingly clear that neither view is satisfactory. Realists disagree about the basis for objective content, and computational neuroscientists and psychologists, while making widespread use of representational talk in articulating their theories, seem indifferent to the efforts of these philosophers to articulate a secure foundation for such talk, suggesting a disconnect between the preoccupations of philosophers of cognitive science and actual practice in these sciences. Fictionalists, for their part, must deny that representational mental states can be causes of cognition and behavior, and that appeal to mental representation can be genuinely explanatory, views that flatly contradict assumptions central to both science and everyday life. I develop and defend a distinctive ‘third way’ – a view I call a deflationary account of mental representation – that both resolves philosophical worries about content and best fits actual practice in science and everyday life. According to the deflationary account, appeal to mental representation does indeed purport to pick out causes of behavior, but the attribution of content to these causes is best understood as a pragmatically motivated gloss, justified in part by attributors’ explanatory interests and goals. Content plays an explanatory role in the deflationary account, but one quite different than that assumed by robust representational realists.
