The late, great, arch-reactionary Fr Jean-Marie Charles-Roux often began his sermons at St Etheldreda’s Church in Holborn, London, with a denunciation of that atheist figurehead of the Enlightenment, Denis Diderot, best known as the editor of the landmark Encyclopédie. Diderot was an appropriate target because he was a fervent atheist in the way we understand the term today. For the most part, thinkers of the Enlightenment weren’t atheists. Voltaire, for example, was typical of this movement, being a Newtonian deist and non-Christian believer in some higher power, designer and creator.
