Habermas's program in formal pragmatics fulfills two main functions. First, it serves as the theoretical underpinning for his theory of communicative action, a crucial element in his theory of society. Second, it contributes to ongoing philosophical discussion of problems concerning meaning, truth, rationality, and action.

By the "pragmatic" dimensions of language, Habermas means those pertaining specifically to the employment of sentences in utterances. He makes clear that "formal" is to be understood in a tolerant sense to refer to the rational reconstruction of general intuitions or competences. Formal pragmatics, then, aims at a systematic reconstruction of the intuitive linguistic knowledge of competent subjects as it is used in everyday communicative practices.
