Thérèse Philosophe (Therese the Philosopher) is a 1748 French novel ascribed to Jean-Baptiste de Boyer, Marquis d'Argens, or, according to a minority opinion, Denis Diderot and others. It has been chiefly regarded as a pornographic novel, which accounts for its massive sales in 18th-century France. The novel represents a public conveyance (and arguably perversion) for some ideas of the Philosophes. Source: Wikipedia (en)
