Where the theory begins to get into the greatest difficulty is where it has to deal with some of the other aspects of contextual defeasibility that we have reviewed above, For example, to handle the simple examples of overt presupposition denial like (181) and (182), the conventional implicature theory is forced to adopt the view that the negative morphemes in natural languages are ambiguous between presupposition-preserving and presupposition-negating senses
