But far more than to his mere congeniality with the social spirit of the French People, or to his literary and scientific fame, or to his kinship with all the liberal tendencies of the eighteenth century in America and Europe, was the success of Franklin at the French court due to those general attributes of mind and character which he brought to every exigency of his private or public life: his good sense, his good feeling, his perfect equipoise, his tact, his reasonableness, his kindly humor. It was these things which, above everything else, enabled him to surmount all the trying difficulties of his situation, and to give to the world the most imposing example of fruitful pecuniary solicitation that it has ever known. The firm hold that he obtained upon the esteem and good will of Vergennes, "that just and good man" he terms him in one of his letters, was but the merited reward of personal qualities which invite, secure and retain esteem and good will under all human conditions. Vergennes, who held the keys of the French money-chest, and directed the policies of France, respected, trusted and liked Franklin, because Franklin, at any rate, duly recognized and acknowledged the generous motives which had, in part, inspired French intervention in the American contest, because he exhibited a considerate appreciation of the sacrifices which it cost France, still bleeding from her last struggle with Great Britain, to make such large and repeated loans to the United States, and because his tactful and discreet applications for pecuniary assistance for his country were never marked by disgusting importunity or thinly veiled menaces. How true this is we have already seen; and its truth is still further confirmed by the testimony of Franklin's successor, Jefferson, who, when asked in Paris, whether he replaced Franklin, was in the habit of replying, "No one can replace him, sir; I am only his successor." After stating the circumstances, including his own association with Franklin at Paris, which had convinced him that the charge of subservience to France, made against Franklin, had not a shadow of foundation, Jefferson pays this impressive tribute to him:
