Communication and shared information

Strawson style counterexamples to Grice’s account of communication show that a communicative intention has to be overt. Saying what overtness consists in has proven to be difficult for Gricean accounts. In this paper, I show that a common explanation of overtness, one that construes it in terms of a network of shared beliefs or knowledge, is mistaken. I offer an alternative, collectivist, model of communication. This model takes the utterer’s communicative intention to be a we-intention, a kind of intention with a distinctive content that cannot be reduced to an intention in favor of an individual action. I show that the collectivist model can explain overtness in terms of a general feature of we-intentions, namely the requirement that the participants in a shared activity are to intend to act in accordance with meshing subplans.
