"The influence [on Jean-Jacques Rousseau] of Jurieu, who in his XVIth, XVIIth and XVIIIth Pastoral Letters (1689) exposed a doctrine of the social contract and popular sovereignty that Bossuet fought in the 5th Warning to Protestants, was pointed out by Proudhon, Idée générale de la révolution au XIXe siècle (General idea of the revolution in the XIXth century), p. 115; — by J. Denis, Bayle et Jurieu (Caen, 1886): "the political doctrine of Pastoral Letters already contained the entire Social Contract of J.-J. Rousseau", p. 56; — by M. Faguet, op. cit. [= Ém. Faguet, La politique comparée de Montesquieu, Rousseau et Voltaire, 1902], p. 73; etc" (Georges Beaulavon, introduction to Jean-Jacques Rousseau, Du Contrat social, Paris, 1903, p. 64, n. 3; online.)
