This is a translation of Nicholas Bonneville's book L'Esprit des Religions from 1792. Bonneville was a leader of a fraternal secret society known as the Cercle Social affiliated to the Bavarian Illuminati. His book clarifies the true Illuminati's political aims. The translator and editor, Di Luchetti, explains in a scholarly manner the latest proof that the Illuminati of Bavaria played a critical role in the French Revolutions of 1789 and 1792, primarily relying upon their allies Bonneville, Mirabeau, and Savalette de Langes. Extensive appendix material provides translations of several pamphlets of the Cercle Social during the 1789-1794 period. These materials clarify the Illuminati had a communistic libertarian agenda.
