In the debate, Derrida praises Austin's work, but argues that he is wrong to banish what Austin calls "infelicities" from the "normal" operation of language. One "infelicity," for instance, occurs when it cannot be known whether a given speech act is "sincere" or "merely citational" (and therefore possibly ironic, etc.). Derrida argues that every iteration is necessarily "citational", due to the graphematic nature of speech and writing, and that language could not work at all without the ever-present and ineradicable possibility of such alternate readings. Derrida takes Searle to task for his attempt to get around this issue by grounding final authority in the speaker's inaccessible "intention". Derrida argues that intention cannot possibly govern how an iteration signifies, once it becomes hearable or readable. All speech acts borrow a language whose significance is determined by historical-linguistic context, and by the alternate possibilities that this context makes possible. This significance, Derrida argues, cannot be altered or governed by the whims of intention.
