This book examines how one aspect of the social and technological situation of literature namely, the postal system determined how literature was produced and what was produced within literature. Language itself has the structure of a relay, where what is transmitted depends on a prior withholding. The social arrangements and technologies for achieving this transmission thus have had a particularly powerful impact on the imagination of literature as a medium. The book has three parts. The first part reconstructs the postal conditions of classic and Romantic literature: the invention of postage in the seventeenth century, which transformed the postal system into a service meant to be used by the population (instead of by the prince alone); the sexualization of letter writing, which was introduced in the middle of the eighteenth century and changed the reading of a letter into an interpretation of intimate confessions of the soul; and Goethe s turning of this new ontology of the letter into a logistics of literature whereby literary authorship was constructed by means of postal logistics, with the precision of engineering.
