Hume, as everybody knows, found "the men of letters really very agreeable; all of them men of the world, living in entire, or almost entire harmony, among themselves, and quite irreproachable in their morals." He places Diderot among those whose person and conversation he liked best. We have always heard much of the power of the Salon in the eighteenth century, and it was no doubt a remarkable proof of the incorporation of intellectual interests in manners, that so many groups of men and women should have met habitually every week for the purpose of conversing about the new books and new plays, the fresh principles and fresh ideas, that were produced by the incessant vivacity of the time. The Salon of the eighteenth century passed through various phases; its character shifted with the intellectual mood of the day, but in all its phases it was an institution in which women occupied a place that they have never acquired in any society out of France. We are not here called upon to speculate as to the reasons for this; it is only worth remarking that Diderot was not commonly at his ease in the society of ladies, and that though he was a visitor at Madame Geoffrin's and at Mademoiselle Lespinasse's, yet he was not a constant attendant at any of the famous circles of which women had made themselves the centre. The reader of Madame d'Epinay's memoir is informed how hard she found it to tame Diderot into sociability. "What a pity," she exclaims, "that men of genius and of such eminent merit as M. Diderot should thus wrap themselves up in their philosophy, and disdain the homage that people would eagerly pay them in any society that they would honour with their presence."[247] One of the soundest social observers of the time was undoubtedly Duclos. His _Considerations on the Manners of the Century_, which was published in 1751, abounds in admirable criticism. He makes two remarks with which we may close our chapter. "The relaxation of morals does not prevent people from being very loud in praise of honour and virtue; those who have least of them know very well how much they are concerned in other people having them." Again, "The French," he said, "are the only people among whom it is possible for morals to be depraved, without either the heart being corrupted, or their courage being weakened." CHAPTER VII.
