This second volume in the series demonstrates how the conspiracy of ‘the Sect’, led by sophisters Voltaire, d'Alembert, and Diderot, passed from the hatred of Christianity to the hatred of kings. Barruel describes their political ideology, founded on the teachings of Montesquieu and Rousseau; the coalescing of the plot against the Thrones with the plot against the Altar; the inundation of anti-monarchical books; the attacks against the aristocracy in France; and their high-level allies, abettors, and confederates among said aristocracy. Exposing the secrecy of the Freemasons in his country, particularly of their occult lodges, while making a distinction between them and their upright British counterparts, Barruel reveals their origins, their systems, and their Mysteries; and, finally, supplies proof of their coalition with the sophisters and their adepts, orchestrated to bring about the destruction of every monarchy on the planet.
