This thesis proposes an examination of social and historic groundings in the thought of Donatien-Alphonse-François, more known as Marquis de Sade (1740-1814). Trough a description of discursive regimens related to a specific vision of the body in France, a historic discontinuity between erotic, libertine, pornographic enunciation forms became evident, and permitted a better comprehension of the philosophic and social liaisons of Sade’s texts to the world of the Ancien Regime. Changes in the ways by which his texts have been comprehended were as well verified, in this case, pointing to the consolidation of certain image of perversity linked to Sade, guiding the historic interpretations of his critic legacy since the 18th century. The reading preferences of the author and the dialogue he evolved with his contemporaries where also observed. These resources leaded to the conclusion that Sade interpreted France and history in general with conservative ideas, translated in a mode of thought permeated by some sceptic stakes. This conservatism also suggests relations of Sade with popular conceptions of body and nature, to which good and evil are symmetrical, so that life is taken as a result of the balance effort generated in this situation.
