The Book vs Writing

“The idea of the book is the idea of totality, finite or infinite, of the signifier; this totality of the signifier cannot be a totality, unless a totality constituted by the signified preexists it, supervises its inscription and its signs, and is independent of it in its ideality. The idea of the book, which always refers to a natural totality, is profoundly alien to the sense of writing. It is the encyclopedic protection of theology and of logocentrism against the disruption of writing, against its aphoristic energy, and, as I shall specify later, against difference in general.” (from "Of Grammatology")
