From code to speaker meaning

This paper has two aims. One is to defend an incrementalist view of the evolution of language, not from those who think that syntax could not evolve incrementally, but from those who defend a fundamental distinction between Gricean communication or ostensive inferential communication (Scott-Phillips, Sperber, Tomasello, originally based on Grice) and code-based communication. The paper argues against this dichotomy, and sketches ways in which a code-based system could evolve into Gricean communication. The second is to assess the merits of the SenderReceiver Framework, originally formulated by David Lewis, and much elaborated and set into an evolutionary context by Brian Skyrms and colleagues, as a framework for thinking about the evolution of language. Despite the great strengths of that framework, and despite the great value of a framework that is both general and formally tractable, I argue that there are critical features of language that it fails to capture
