[8] It was stated in the Traité as a commonplace that a form of Spinozism had become popular particularly in educated French circles, that its appeal was both its systematic character and the opportunities it afforded for sniping against the Bible and miracles, and that Spinoza had not in fact died an atheist as had been alleged, in Pierre Bayle's account.
[9] The main religious battle had now shifted, Le Vassor argued as many others did at the time, to face general impiety rather than just Protestant views, and an "enlightened" Christianity was required to provide effective opposition to free-thought.

[19] Other works were the Histoire du règne de Louis XIII (Amsterdam, from 1700, ten volumes) and An account of the present state and government of the Empire of Germany (1711) addressed to Thomas Foley, on the death of Joseph I, Holy Roman Emperor.
The history of Louis XIII was a virulent anti-Catholic work; at the time of its publication Le Vassor was tutor to Henry Bentinck, known by the courtesy title Viscount Woodstock.
