Voltaire’s influence in Québec has been well documented since Marcel Trudel’s 1945 book; see also the articles I have been given to the Cahiers Voltaire for the last fifteen years. Jean-Jacques Rousseau’s presence, on the other hand, has not been studied, with the exception of an article by Monique Moser-Verrey (1987). It is nonetheless important in literary texts as well as in the media, as shown by the students’ general strikes of 2012 and by a growing number of texts dealing with the way the self is expressed today (Catherine Mavrikakis, Jean-Philippe Martel, Nicolas Lévesque, René Bolduc, Thomas O. St-Pierre). I want to shed light on this constant and profound, if disperse, influence.
