Jacques-André Naigeon

Jacques-André Naigeon (July 15, 1738, Paris – 28 February 1810, Paris) was a French artist, atheist philosopher, editor and man of letters best known for his contributions to the Encyclopédie and for reworking Baron d'Holbach's and Diderot's manuscripts.

After trying his hand at painting and sculpture, Naigeon became a friend and associate of Denis Diderot, whom he helped to work on the Encyclopédie. He soon became involved with the Coterie Holbachique, a group of radical French Enlightenment thinkers centered on the Paris salon of Baron d'Holbach. Naigeon quickly adopted the Baron's atheist principles and collaborated with him on his works, overseeing their clandestine printing in Amsterdam and editing d'Holbach's Morale Universelle and his Essai sur les préjugés. Priding himself on a through knowledge of the classics, Naigeon would also edit a French translation of the works of Seneca begun by Nicolas La Grange, publishing it along with Diderot's Essai sur les régnes de Claude et de Néron (Paris, 1778). Other editorial work included the Essays of Montaigne, and a translation of Toland’s philosophical letters

Naigeon became the editor, compiler, and commentator of Diderot's works after the latter made him his literary executor. He published an incomplete edition of Diderot's works in 1798 after writing Mémoires historiques et philosophiques sur la vie et les ouvrages de Diderot, an unfinished commentary on his life and works.

Naigeon's only original stand-alone work was Le militaire philosophe, ou Difficultés sur la religion, proposées au Pére Malebranche (London and Amsterdam, 1768) which was based on an earlier anonymous manuscript, and whose final chapter was written by d'Holbach. This work mostly repeated the atheist, anti-Christian, determinist materialist arguments found in the radical literature of the second half of the 18th century.
