There was a calm about the too few years he passed at Montmorency, which leaves us in doubt whether this mania would ever have afflicted him, if his natural irritation had not been made intense and irresistible by the cruel distractions that followed the publication of Emilius. He was tolerably content with his present friends. The simplicity of their way of dealing with him contrasted singularly, as he thought, with the never-ending solicitudes, as importunate as they were officious, of the patronising friends whom he had just cast off.[15] Perhaps, too, he was soothed by the companionship of persons whose rank may have flattered his vanity, while unlike Diderot and his old literary friends in Paris, they entered into no competition with him in the peculiar sphere of his own genius. Madame de Boufflers, indeed, wrote a tragedy, but he told her gruffly enough that it was a plagiarism from Southerne's Oroonoko.[16] That Rousseau was thoroughly capable of this pitiful emotion of sensitive literary jealousy is proved, if by nothing else, by his readiness to suspect that other authors were jealous of him. No one suspects others of a meanness of this kind unless he is capable of it himself. The resounding success which followed the New Heloïsa and Emilius put an end to these apprehensions. It raised him to a pedestal in popular esteem as high as that on which Voltaire stood triumphant. That very success unfortunately brought troubles which destroyed Rousseau's last chance of ending his days in full reasonableness.
