"A theory of interpretation" [...] At the heart of this theory is a convention, in Lewis's sense, about the use of language. The idea is this. In using an expression sincerely, the speaker intends the listener to come to a unique interpretation of what he has said - not from the meanings of the words alone, but also on the assumption that the speaker has good grounds for thinking that the listener can come to that interpretation uniquely on the basis of what they mutually know. Thus convention is obviously akin to Grice's cooperative principle [Grice, H. P., 1975, Logic and conversation. Syntax and semantic, III, Speech acts, New York, Academic Press].
