In Lautréamont and Sade, originally published in 1949, Maurice Blanchot forcefully distinguishes his critical project from the major intellectual currents of his day, surrealism and existentialism. Today, Lautréamont and Sade, these unique figures in the histories of literature and thought, are as crucially relevant to theorists of language, reason, and cruelty as they were in post-war Paris.

"Sade's Reason," in part a review of Pierre Klossowski's Sade, My Neighbor, was first published in Les Temps modernes. Blanchot offers Sade's reason, a corrosive rational unreasoning, apathetic before the cruelty of the passions, as a response to Sartre's Hegelian politics of commitment.
