Percus & Sauerland (2003) use quantified belief reports of the form 'Only Peter thinks he's...' to argue for dedicated de se LFs. The argument is targeted against any reductionist account that sees de se as merely a particular subtype of de re, viz. a de re belief about oneself from a first person perspective, requiring nothing but an account of de re attitudes. My acquaintance resolution framework is an attempt at just such a reduction and in this paper I extend (...) that theory with a projection mechanism to allow local accommodation of acquaintance relations. With this extension we can account for their data, as well as for some related data involving quantified belief reports familiar from arguments in the de se literature.
