Using Proper Names as Intermediaries Between Labelled Entity Representations

This paper studies the uses of proper names within a communication-theoretic setting, looking at both the conditions that govern the use of a name by a speaker and those involved in the correct interpretation of the name by her audience. The setting in which these conditions are investigated is provided by an extension of Discourse Representation Theory, MSDRT, in which mental states are represented as combinations of propositional attitudes and entity representations (ERs). The first half of the paper presents the features of this framework that are needed to understand its application to the account of names that follows. N-labelled entity representations, where N is a proper name, play a pivotal part in this account: A speaker must have an N-labelled ER in order to be in a position to use a name N, and the interpreter must either have such a representation, or else construct one as part of his interpretation. The paper distinguishes different types of name uses in terms of what they presuppose about the role of N-labelled ERs on the side of the interpreter.
