  Nonetheless, drawing on Cohen 1964, Lycan 2018 objects to the view that such performative frames make no contribution to sentence or utterance meaning. If Marissa felicitously utters, ‘I claim that it is sunny,’ while Abdul felicitously utters, ‘I conjecture that it is sunny,’ the view implies that their utterances mean the same. The two speakers have clearly said different things, however. On the other hand, if we hold that the performative frame does contribute to the content of what Marissa and Abdul said, then, Lycan points out, it will be difficult to explain how their utterances commit either of them to any position about the weather. It evidently won’t do to posit inference rules such as ‘I state that p,‘ ergo, ‘p’. We will consider a solution to what Lycan terms “Cohen’s Problem” after developing a notion of illocutionary inference in the next section.
