Note 175 — Chapter XVII · FRENCH FREETHOUGHT IN THE EIGHTEENTH CENTURY

24. Over all of these men, and even in some measure over Voltaire, Diderot (1713–1784) stands pre-eminent, on retrospect, for variety of power and depth and subtlety of thought; though for these very reasons, as well as because some of his most masterly works were never printed in his lifetime, he was less of a recognized popular force than some of his friends. In his own mental history he reproduces the course of the French thought of his time. Beginning as a deist, he assailed the contemporary materialists; in the end, with whatever of inconsistency, he was emphatically an atheist and a materialist. One of his most intimate friends was Damilaville, of whom Voltaire speaks as a vehement anti-theist;175 and his biographer Naigeon, who at times overstated his positions but always revered him, was the most zealous atheist of his day.176
