 Hare 1989 replies that there could be a society with a convention that utterance of a certain expression constituted performance of a certain illocutionary act, even those utterances that occur on stage or as used by jokers or storytellers. Green 1997 questions the relevance of this observation to asserting, which as we have seen, which as we have seen, seem to require intentions for their performance. Just as no convention could make it the case that I believe that P, so too no convention could make it the case that I intend to put forth a certain sentence as an assertion.
