Dispositionalism, Yay! Representationalism, Boo!

Abstract According to dispositionalism, a person believes when they have the relevant pattern of behavioral, phenomenal, and cognitive dispositions. According to representationalism, a person believes when the right kind of representational content plays the right kind of causal role in their cognition. Representationalism overcommits on cognitive architecture, reifying a cartoon sketch of the mind. In particular, representationalism faces three problems: the Problem of Causal Specification (concerning which specific representations play the relevant causal roles), the Problem of Tacit Belief (concerning which specific representations any one person has stored, among the hugely many approximately redundant possible representations), and the Problem of Indiscrete Belief (concerning how to model gradual belief change and in-between cases of belief). Dispositionalism, in contrast, is flexibly minimalist about cognitive architecture, focusing appropriately on what we should and do care about in belief ascription.
