[...] The end-point of deconstructive thought, as Derrida insists, is to recognize that there is no end to the interrogative play between text and text. Deconstruction can never have the final word because its insights are inevitably couched in a rhetoric which itself lies open to further deconstruction reading. Criticism can only be deluded in its claim to operate (as Eagleton puts it) 'outside the space of the text' on a plane of scientific knowledge. There is no metalanguage.
