The weak Marmontel, who, according to his own description, was only fitted for superficial conversation and writing, boasts of the prudence, foresight and skill of his protectress, and shows how she understood the way to gain the confidence of others without ever yielding her own. This distinguished art made the house of Madame Geoffrin invaluable to the great world, and to those learned men who wished to shine in this kind of society, and to cultivate and avail themselves of it, for such people must learn above all things neither to say too much nor too little. This society, indeed, was not calculated for any length of time for a Rousseau or a Diderot. Even the great admirers of Geoffrin admit that _savoir vivre_ was her highest knowledge, she had very few ideas with respect to anything besides; but in the knowledge of all that pertained to the manners and usage of good society, in the knowledge of men, and particularly of women, she was deeply learned, and was able to give some very useful instructions. It would lead us too far into the history of the following period, to enumerate and characterize the members of these regular societies. It may suffice to mention, that in addition to all the guests who frequented Madame de Tencin's, all the friends of Voltaire's school, and at first also Rousseau, made a part of the society at the house of Madame Geoffrin. We have already remarked that no prince, minister, or distinguished man of all Europe came to Paris who did not visit Madame Geoffrin, and think it an honor to be invited to her house, because he there found united all that was exclusively called talent in Europe. Kaunitz also, who was then only a courtier in Versailles, came to Madame Geoffrin's parties. He was a man who combined in a most surprising manner true philosophy and a deep knowledge of political economy, with the outward appearance of a fop and a trifler. Among the other distinguished men who lived in Paris, Marmontel names with high praise the Abbé Galliani, Caraccioli, who was afterward Neapolitan ambassador, and the Swedish ambassador, Count Creutz.
