Let us being again. To take some examples: why should “literature” still designate that which already breaks away from literature—away from what has always been conceived and signified under that name—or that which, not merely escaping literature, implacably destroys it? (Posed in these terms, the question would already be caught in the assurance of a certain fore-knowledge: can “what has always been conceived and signified under that name” be considered fundamentally homogeneous, univocal, or nonconflictual?) To take other examples: what historical and strategic function should henceforth be assigned to the quotation marks, whether visible or invisible, which transform this into a “book,” or which still make the deconstruction of philosophy into a “philosophical discourse”?
