 Recent work in Evolutionary Game Theory has also lent credence to the emergence of signaling systems involving non-intentional states. Taking Lewis (1969) as a spring-board, Skyrms (2010) investigates the structure of signaling behavior beyond the existence of mutual conventions. His framework starts from the most basic non-trivial cases and gradually introduces complexity (such as deception and the introduction of new signals etc.). Skyrms’ account views propositional or semantic content as a special case of informational content thereby reintroducing information theory as a tool to philosophers of language and linguistics interested in the emergence of linguistic communication and/or semantic meaning.
