The Searle–Derrida debate began in 1972, when, in his paper "Signature Event Context", Derrida analyzed J. L. Austin's theory of the illocutionary act. While sympathetic to Austin's departure from a purely denotational account of language to one that includes "force", Derrida was sceptical of the framework of normativity employed by Austin. He argued that Austin had missed the fact that any speech event is framed by a "structure of absence" (the words that are left unsaid due to contextual constraints) and by "iterability" (the repeatability of linguistic elements outside of their context). Derrida argued that the focus on intentionality in speech-act theory was misguided because intentionality is restricted to that which is already established as a possible intention. He also took issue with the way Austin had excluded the study of fiction, non-serious or "parasitic" speech, wondering whether this exclusion was because Austin had considered these speech genres governed by different structures of meaning, or simply due to a lack of interest.
