No necessita-
tion, no semantic presupposition.
(8), though interrogative, meets a similar fate. If you are married and you
are asked (8) (and you have never beaten your spouse), here is the correct
answer: "No."6 Because one can stop doing a thing only if one has at some
time been doing it. (Of course the answer "No" is misleading because, via
the Maxim of Strength, it implicates that one has beaten one's spouse and
continues to do so. The correct and nonmisleading answer would be, "No,
because I never have beaten her/him in the first place.")
(9) is possible to dismiss in this way, but harder.
(9)Rocky did not realize that his fly was open; he could hardly have
realized that, because his fly wasn't open
does not seem contradictory either; but there is not so obvious a Gricean
explanation of (9a)'s negation implicating (9b).
(10) is perhaps the best alleged example of semantic presupposition on our
list.
