[23] See "Outwork, prefacing," in Dissemination , 2–59. The supplementarity of prefacing is presented by Derrida pretty much as something Hegel encounters (or is oblivious of), outside his project, unwillingly, as an effect of a blindness. In this sense Chaucer's prologue is unlike one view of The Phenomenology of Mind because the poem is patently not finished and does not, therefore, form a completed system and because the prologue itself points conspicuously to the inadequacy of its prefacing. Hence it becomes, as I say in the text, an analysis of the impulse to such completion rather than an instance of it. What if these things were true of "Hegel" as well? Though de Man raised this question with respect to Derrida's reading of Rousseau in Blindness and Insight , and Harry Berger, Jr., has raised it about the reading of Plato in "Plato's Pharmacy," it has never to my knowledge been followed up.
