Nothing can form a stronger contrast to the general passion of the French character for change, than its devotion to the same coterie for half a century together. In the middle of the eighteenth century two houses in Paris were especially the rendezvous of the talkers, idlers, and philosophers of Paris. That some of those visitants were men of remarkable ability, there can be no doubt. But this perpetual haunting of the same coffee-cups, this regularity of trifling, this wretched inability to remain at home for a single evening, is so wholly irreconcilable with our English sense of domestic duties, of the attachment of parents to their families, and of the exercise of the natural affections, that we find it utterly impossible to attach any degree of respect to the perpetual lounger at another's fire-side. Madame Geoffrin had now succeeded to Madame de Tencin, as the receiver of the coterie. Madame du Deffand held a kind of rival, but inferior, coterie. The former had a house, the latter had only a lodging; the former was good-humoured, amiable, and kind--the latter satirical and cold; but both were clever, and, at all events, both received the gossips, wise and foolish, of Paris. At the lodging of Madame du Deffand, D'Alembert met Mademoiselle de l'Espinasse, a species of companion to Madame. She was the illegitimate daughter of a woman of fashion, as D'Alembert was the son. The circumstance was too common in Parisian high life, to involve any censure on the parents, or any disgrace on the children; but it may have produced a degree of sympathy, which suddenly rose to its height by their taking a lodging together! Those things, too, were so frequent in France, that, except the laugh of the moment, no one seems to have taken notice of the connexion; and they continued to carry it on, as well received as ever, and holding their evening coterie with undiminished applause. "No one," observes the noble biographer, "whispered a syllable of suspicion, respecting a connexion which all were fully convinced could be only of the most innocent kind." This French credulity is too simple for our credence. That a he and she philosophic pair should have lived in the same apartments for a dozen years with perfect innocency, may have been the case in Paris; but the story would not be believed in any less immaculate region on the face of the earth. The plain truth seems to be, that the general looseness of Parisian society saw nothing gross in the grossest connexion. Even where they affected virtue, they palpably preferred their having an evening lounge open to them, to any consideration grounded on common propriety and a sense of shame.
