I read "Are you leaving -- or not" to mean:"Well, go, goddamnit. Go! Get the hell out of here!" -- but a bit more civil than that. Whereas "Are you leaving?" seems to be a straight forward question.> If these different nuances or "implicatures" exist, they are dependent on things like tone and context. Mike would surely read "Are you leaving --- or not?" quite differently if said by an attractive female who before adding "or not" dropped the only clothing she was wearing to the floor. He is letting non-logical considerations and assumptions get in the way of straightforward propositional analysis, where "Are you leaving or the negation of that?" is equivalent to "Are you leaving?" and also to "Are you not leaving?" - because to raise something as a possibility in this way also, by implication, raises its negation as a possibility. Mike, Mike? Concentrate on the logic goddammit and stop imagining that woman mentioned above.
