Lepore and Stone's articulation of direct intentionalism offers a strategy for combining into a unified theory both fundamental philosophical theories concerning the nature of intentions and cooperative activity and empirical theories in linguistics and cognitive science concerning the particular mechanism of natural languages. This is a significant accomplishment.... I wholeheartedly recommend their book for anyone interested in the relationship between conventional meaning and cooperative rational action and the attendant issue of how to understand the relationship between pragmatics and semantics.
