We are analysing Christopher Reeve's implicature in the little conversation with Oprah Winfrey: WINFREY: So ... You think it's possible you will walk again, then? REEVE: Actually, I think it's *very* possible I will walk again. WINFREY: And what would happen if you won't? REEVE (bluntly): Then I won't walk again. P. A Stone suggest the implicature is: >>"I'm saying I can walk again >>to give all spine-injured people hope. >>I don't *really* think I will; but I might >>as well do the best I can with what >>I've got. Right. Now the question is how you derive that implicature out of Grice's conversational maxims! There are tricky issues here in that if 'if' is truth-functional, then the addition of the particle 'then' (as in Reeve's reply, "_Then_ I won't walk again") may turn the operation non-truth-functional. We should also consider whether 'when' is equivalent to 'if'. I agree with Paul that "I might as well do the best I can with what I've got." In his _Pragmatics_ (Cambridge Textbooks in Linguistics, paperback) S. C. Levinson considers the implicature of A: I miss John. Do you think he'll come to the party? B: Either he will or he won't. Levinson suggests the implicature is +> There's nothing we can do about it. The logical form of B's utterance is slightly different (it's a tautologous disjunction, to use Geary's parlance). In the case of Reeve's utterance it concerns what Aristotelians would have as a 'contingent future'. And there's no 'or' involved. Only cancellation of possibility, as expressed by arrogant Oprah.
