Abstract  The Problem of Doxastic Shift may be stated as a dilemma: on the one hand, the distribution of nominal complements of the form `the that p strongly suggests that `that-clauses cannot be univocally assigned propositionaldenotations; on the other hand, facts about quantification strongly suggest that `that-clauses must be assigned univocal denotations. I argue that the Problem may be solved by defining the extension of a proposition to be a set of facts or, more generally, conditions. Given this, the logical operation of descriptive predication can be introduced in a way that resolves the dilemma withoutsacrificing the singular term analysis of `that-clauses.
