The rivalry between the schools of Rousseau and Voltaire represents the dead-lock to which social thought had come; a dead-lock of which the catastrophe of the Revolution was both expression and result. At the time of Voltaire’s death there was not a single institution in France with force enough to be worth a month’s purchase. The monarchy was decrepit; the aristocracy was as feeble and impotent as it was arrogant; the bourgeoisie was not without aspiration, but it lacked courage and it possessed no tradition; and the church was demoralised, first by the direct attack of Voltaire and the not less powerful indirect attack of the Encyclopædia, and second by the memory of its own cruelty and selfishness in the generation just closing. But Voltaire’s theory, so far as he ever put it into its most general form, was that the temporal order was safe and firm, and that it would endure until criticism had transformed thought and prepared the way for a régime of enlightenment and humanity. Rousseau, on the contrary, directed all the engines of passion against the whole temporal fabric, and was so little careful of freedom of thought, so little confident in the plenary efficacy of rational persuasion, as to insist upon the extermination of atheists by law. The position of each was at once irrefragable and impossible. It was impossible to effect a stable reconstitution of the social order until men had been accustomed to use their minds freely, and had gradually thrown off the demoralising burden of superstition. But then the existing social order had become intolerable, and its forces were practically extinct, and consequently such an attack as Rousseau’s was inevitable, and was at the same time and for the same reasons irresistible. To overthrow the power of the church only was to do nothing in a society perishing from material decay and political emasculation. Yet to regenerate such a society without the aid of moral and spiritual forces, with whose activity the existence of a dominant ecclesiastical power was absolutely incompatible, was one of the wildest feats that ever passionate sophist attempted.
