 An especially detailed effort along these lines comes from Elisabeth Camp (2006); only one of her arguments can be reviewed here. Some time back the linguist Larry Horn drew attention to “the phenomenon of metalinguistic negation—a device for objecting to a previous utterance on any grounds whatever, including the conventional or conversational implicata it potentially induces, its morphology, its style or register, or its phonetic realization” (Horn, 1988, 381). Consider “It wasn’t warm, it was sweltering,” where of course, if it was sweltering, it follows that it was warm as well. In many circumstances, a form of words the contextualist regards as reserved for denying what is said can in fact be pressed into service to deny one or another associated, unexpressed proposition. Camp contends that this renders direct denial diagnostics for what is said systematically unreliable. If she’s right about this, direct affirmation diagnostics and direct questioning diagnostics will be in trouble for the same sort of reason.
