"I assure you that my friends and I will lead them a fine dance; they shall drink the cup to the very lees," wrote Voltaire to D'Alembert.

In the great campaign against Christianity undertaken by the philosophers, Voltaire, so long, a wavering ally, will henceforth fight in the foremost ranks; it is he who shouts to Diderot, "Squelch the thing (_Ecrasez l'infame_)!" The masks are off, and the fight is barefaced; the encyclopaedists march out to the conquest of the world in the name of reason, humanity, and free-thinking; even when he has ceased to work at the Encyclopaedia, Voltaire marches with them.
The _Essai sur l'Histoire generale et les Moeurs_ was one of the first broadsides of this new anti-religious crusade.

"Voltaire will never write a good history," Montesquieu used to say: "he is like the monks, who do not write for the subject of which they treat, but for the glory of their order: Voltaire writes for his convent." The same intention betrayed itself in every sort of work that issued at that time from the hermitage of Delices, the poem on _Le Tremblement de Terre de Lisbonne,_ the drama of _Socrate,_ the satire of the _Pauvre Diable,_ the sad story of _Candide,_ led the way to a series of publications every day more and more violent against the Christian faith.

The tragedy of _L' Orphelin de la Chine_ and that of _Tancrede,_ the quarrels with Freron, with Lefranc de Pompignan, and lastly with Jean Jacques Rousseau, did not satiate the devouring activity of the Patriarch, as he was called by the knot of philosophers.

Definitively installed at Ferney, Voltaire took to building, planting, farming.
