Sometimes, there are reasons for which we believe, intend, resent, decide, and so on: these reasons are the “bases” of the latter, and the explanatory relation between these bases and the latter is what I will call “the basing relation.” What kind of explanatory relation is this? Dispositionalists claim that the basing relation consists in the agent's manifesting a disposition to respond to those bases by having the belief, intention, resentment, and so on, in question. Representationalists claim that the basing relation consists in the agent's representing the bases as justifying the belief, intention, resentment, and so on, in question. This article shows that an adequate account of the basing relation requires a particular refinement and combination of these two views. On the hybrid account defended here, the basing relation involves a disposition exercise that is individuated by the agent's object-involving de se representation of that very exercise as justifying.
