Both the distinction between de re and de dicto beliefs, and the distinction between referential and attributive uses of definite descriptions have seemed, to some philosophers, to be of somewhat dubious status. While admitting that there is, in each case, some sort of distinction to be drawn, they have been inclined to think that these distinctions are not relevant to the philosophical questions being asked about beliefs and descriptions. Philosophers have, for example, been concerned with the structure of beliefs, where this can be understood to mean the structure of believed propositions; and they have been concerned with the analysis of sentences containing definite descriptions. But, it is thought, these two distinctions have no bearing on propositional structure or on sentence meaning. They have, in short, no semantic significance.
