Students of the Enlightenment have long assumed that the major movement towards atheism in the Ancien Régime was centered in the circle of intellectuals who met at the home of Baron d'Holbach during the last half of the eighteenth century. This major critical study shows, contrary to the accepted views, that in fact, atheism was not the common bond of a majority of the members and that, far from being alienated figures, most of the members were privileged and publicly successful citizens devoted to peaceful and gradual reform. Alan Charles Kors determines the coterie's membership and discovers it to have been a diverse assemblage of philosophes, men of letters, and scientists. Analyzing the thought and behavior of those members who lived past 1789, the author argues that the hostility to the Revolution expressed by the coterie's survivors was fully consistent with their world view. Originally published in 1976. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
