A number of authors have pointed out that the standard arguments for perception’s having nonconceptual content tell us nothing about the content of a state per se, but only instead about the sorts of capacities a subject must have in order to be in some state (i.e., whether the subject need or need not possess the specifying concepts in order to be in some state). Others have argued in response that the only reason for two states to require different conceptual capacities of the subject is precisely because they have different sorts of contents, and so there is no substantive difference between a ‘content’ view and a ‘state’ view. Here, I present evidence for states that do, in fact, share the same content but differ in the required conceptual capacities: exogenous perceptual states, and endogenous, voluntarily produced perceptual states. I argue that this functional difference—voluntary versus involuntary production—constitutes the difference in concept-dependence. I then look to three possibilities for how this claim could affect our understanding of the relationship between cognition and perception.
Brooklyn Public Philosophers is a forum for philosophers in the greater Brooklyn area to discuss their work with a general audience, hosted by the Brooklyn Public Library. Its goal is to raise awareness of the best work on philosophical questions of interest to Brooklynites, and to provide a civil space where Brooklynites can reason together about the philosophical questions that matter to them.
