The problem posed by indirect speech acts is the problem of how it is possible for the speaker to say one thing and mean that but also to mean something else.
John SearleThe assertion fallacy is the fallacy of confusing the conditions for the performance of the speech act of assertion with the analysis of the meaning of particular words occurring in certain assertions.
John SearleIn the performance of an illocutionary act in the literal utterance of a sentence, the speaker intends to produce a certain effect by means of getting the hearer to recognize his intention to produce that effect; and furthermore, if he is using the words literally, he intends this recognition to be achieved in virtue of the fact that the rules for using the expressions he utters associate the expression with the production of that effect.
