Voltaire is one of the greatest writers in the French language, but readers and researchers have so far lacked access to a definitive scholarly edition. The Complete Works of Voltaire (Œuvres complètes de Voltaire) being published by the Voltaire Foundation is the first critical edition of the totality of his writings (in the original French), arranged chronologically to untangle the evolution of his thought. Each text is revealed anew thanks to an introduction, variants and a comprehensive annotation (in either English or French).

For more on Voltaire’s ‘modern history’ texts, see Voltaire: historian of modernity. For more on his alphabetical collections, see Voltaire and alphabetical collections. For more on his contes, see Voltaire’s contes.

Volume 70A: Writings of 1769 IIA

Ed. Basil Guy, Diana Guiragossian-Carr et al.

The texts in this volume (OCV 70A) date from 1769. Voltaire, energetic despite his 75 years, continues his struggle against ‘l’infâme’ and promotes tolerance. There is also an épître against atheism, containing his famous line ‘Si Dieu n’existait pas, il faudrait l’inventer’. There are attacks on abuses by the clergy and on figures he considered the enemies of Enlightenment, including Malebranche and Jean-Jacques Rousseau, but also a celebration of the glories of French literature.
