Oeuvres philosophiques de Mr. D ***

First collected edition but not authorized by the author. It contains 25 plates including 3 frontispieces and several with geometry diagrams. Handsome edition, elegantly composed and printed, but it contains four texts that are not by the author: Le Code de la Nature by Morelly, Les Principes de Philosophie Morale by Étienne Beaumont, La Justification de Plusieurs Articles de l'Encyclopédie by Abbé Monlinot, and Lettre au P. Berthier sur le Matérialisme by Abbé Coyer. Originally, Marc-Michel Rey had an editorial project with Diderot for his works, but this project was aborted. Multiple paginations, each text having its own pagination and table of contents.
