the philosophical interpretation of language game theory
I give an informal presentation of the evolutionary game theoretic approach to the conventions that
constitute linguistic meaning. The aim is to give a philosophical interpretation of the project, which
accounts for the role of game theoretic mathematics in explaining linguistic phenomena. I articulate
the main virtue of this sort of account, which is its psychological economy, and I point to the casual
mechanisms that are the ground of the application of evolutionary game theory to linguistic phenomena.
Lastly, I consider the objection that the account cannot explain predication, logic, and
compositionality
Coevolution of Lexical Meaning and Pragmatic Use
According to standard linguistic theory, the meaning of an utterance is the product of conventional semantic meaning and general pragmatic rules on language use. We investigate how such a division of labor between semantics and pragmatics could evolve under general processes of selection and learning. We present a game‐theoretic model of the competition between types of language users, each endowed with certain lexical representations and a particular pragmatic disposition to act on them. Our model traces two evolutionary forces and their interaction: (i) pressure toward communicative efficiency and (ii) transmission perturbations during the acquisition of linguistic knowledge. We illustrate the model based on a case study on scalar implicatures, which suggests that the relationship between underspecified semantics and pragmatic inference is one of coevolution
