David Lewis on convention

Abstract

This chapter presents an overview of Lewis’s theory of convention, and explores its implications for linguistic theory, and especially for problems at the interface of the semantics and pragmatics of natural language. It discusses Lewis’s understanding of coordination problems, emphasizing how coordination allows for a uniform characterization of practical activity and of signaling in communication. The chapter introduces Lewis’s account of convention and shows how he uses it to make sense of the idea that a linguistic expression can come to be associated with its meaning by a convention. Lewis’s account has come in for a lot of criticism. The chapter closes in by addressing some of the key difficulties in thinking of meaning as conventional in Lewis’s sense. It highlights that Lewis’s contribution is achieved through ideas whose influence has only increased over time.
