At his town house in Paris and on his country estate at Grandval, D'Holbach entertained writers, philosophers, and other men of influence. His salon contributed much to the development and communication of 18th-century thought; but D'Holbach himself made a more direct contribution. This master of five languages wrote and studied continuously. In the 1750s he translated [[Germany|German]] [[science|scientific]] articles, and he contributed almost 400 such articles to Denis [[Diderot]]'s Encyclopédie.

In 1761 began D'Holbach's written attacks on theologians and religious power. Under the name of his deceased friend N. A. Boulanger, D'Holbach published Le Christianisme dévoilé, a critical examination of Christianity. D'Holbach often resorted to pseudonyms or anonymity to protect himself from the conservative and repressive authorities. In the 1770s D'Holbach produced his positive substitutes for the religious and political dogmas he despised: Système de la Nature (1770), a [[secularism|secular]] ethics detailing the interrelation of ethics and government; Le Bon sens (1772; Good Sense), a very readable restatement of the radical ideas of the 1770 work; Politique naturelle (1773), a discussion of the moral influences exercised by government; and Morale universelle (1776), regarded by some as his [[ethics|ethical]] masterpiece.
