In his brief reply to Derrida, "Reiterating the Differences: A Reply to Derrida", Searle argued that Derrida's critique was unwarranted because it assumed that Austin's theory attempted to give a full account of language and meaning when its aim was much narrower. Searle considered the omission of parasitic discourse forms to be justified by the narrow scope of Austin's inquiry. Searle agreed with Derrida's proposal that intentionality presupposes iterability, but did not apply the same concept of intentionality used by Derrida, being unable or unwilling to engage with the continental conceptual apparatus. This, in turn, caused Derrida to criticize Searle for not being sufficiently familiar with phenomenological perspectives on intentionality. Searle also argued that Derrida's disagreement with Austin turned on his having misunderstood Austin's (and Peirce's) type–token distinction and his failure to understand Austin's concept of failure in relation to performativity. One critic has suggested that Searle, by being so grounded in the analytical tradition, was unable to engage with Derrida's continental phenomenological tradition and was at fault for the unsuccessful nature of the exchange.
