But the 'implicature' of such a question is surely that we read it as asking "How aften are there only 28 days, and no more or less, in February?". ---- Grice loved trick questions, as that per the title. I found out that the earliest equivalent in Latin logic was: Tu no cessas edere ferrum You cease to eat iron. ----- Grice dedicates 65 pages of his "Causal Theory of Perception" -- now online in S. Bayne's history-of-analytic-philosophy website -- to the trick question. For him, the implicature holds in the negative, not in the affirmative: No, I have not stopped because I never started. Yes, I have stopped -- and I feel relieved about that (<---- for scenarios of the hubby-beating wife). I had forgotten that Stubbs (who also mentions the "Jeopardy" Henry-VIII's number of wives, also mentions the leap year. How many balls (at least) must a bat have? Similarly, for the question, "Where is your wife?" "In the dining room or in the kitchen" -- the implicature is cancellable for houses with a passage that connects both, and when the wife is lying in between. Cheers, J.
