Abstract

This paper proposes a way of semantically representing de re belief ascriptions that involves contextual resolution of the acquaintance relation between the attitude holder and the object about which the attitude is de re. A special case is that where the belief is about the believer herself. Here, we may discern two possibilities: the acquaintance relation is equality, in which case we end up with a de se belief, or, if the first option fails, we search the context for a different suitable relation of acquaintance between the believer and herself, like looking in a mirror or seeing yourself on TV. This second option leaves open the possibility that the believer herself is unaware of the fact that she's actually seeing herself, thereby accounting for the true reading (de re/non-de se) of ``Lain believes she will win'' in mistaken identity scenarios. To implement all this formally, I use a two-dimensionally modal extension of DRT, and second order binding and unification.
