ONE TASK OF LITERATURE is to formulate questions and construct counterstatements to the reigning pieties. And even when art is not oppositional, the arts gravitate toward contrariness. Literature is dialogue; responsiveness. Literature might be described as the history of human responsiveness to what is alive and what is moribund as cultures evolve and interact with one another.
— Susan Sontag, from her 2003 speech accepting the German Friedenspreis
