Abstract: This study examines the dreams of thoughts that were kept secret and then revealed posthumously, which spread through the world of the Parisian academies and were then manifested in the form of fiction in clandestine literature: the Abbé de Saint-Pierre, Duclos, Fontenelle, D’Alembert, and d’Holbach are decisive milestones in this discourse, which articulates the issues of the “double doctrine” in the context of the academies.
