 Strawson’s explanation for these facts is given in terms of topicality. The most likely purpose of a sentence like (45a) is to describe what Jones has been doing in the morning, rather than, say, who the local swimming pool was visited by. That is, in the absence of further information about the context in which this sentence is uttered, its topic will be Jones’s exploits. Similarly, a sentence like (45b) will normally be used to convey information about the exhibition. If so, although the sentence purports to refer to the king of France, it is not about him; the king of France is not the topic of discourse, nor part of the topic. In other words, the existence of the king of France is not at-issue. Strawson’s suggestion is that this circumstance influences the way presupposition failure is dealt with. On this view, presupposition failure results in infelicity only if it affects the topic of a sentence; otherwise the sentence will be judged true or false, as appropriate.
