 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.
