À rebours (French pronunciation: ​[a ʁə.buʁ]; translated Against Nature or Against the Grain) (1884) is a novel by the French writer Joris-Karl Huysmans. Its narrative concentrates almost entirely on its principal character and is mostly a catalogue of the tastes and inner life of Jean des Esseintes, an eccentric, reclusive aesthete and antihero who loathes 19th-century bourgeois society and tries to retreat into an ideal artistic world of his own creation. À rebours contains many themes that became associated with the Symbolist aesthetic. In doing so, it broke from Naturalism and became the ultimate example of "decadent" literature.
