The son of a father to whom history will accord certain attenuating circumstances, but also as worthy of esteem as that father had been of blame; possessing all private virtues and many public virtues; careful of his health, of his fortune, of his person, of his affairs, knowing the value of a minute and not always the value of a year; sober, serene, peaceable, patient; a good man and a good prince; sleeping with his wife, and having in his palace lackeys charged with the duty of showing the conjugal bed to the bourgeois, an ostentation of the regular sleeping-apartment which had become useful after the former illegitimate displays of the elder branch; knowing all the languages of Europe, and, what is more rare, all the languages of all interests, and speaking them; an admirable representative of the "middle class," but outstripping it, and in every way GRE ater than it; possessing excellent sense, while appreciating the blood from which he had sprung, counting most of all on his intrinsic worth, and, on the question of his race, very particular, declaring himself Orleans and not Bourbon; thoroughly the first Prince of the Blood Royal while he was still only a Serene Highness, but a frank bourgeois from the day he became king; diffuse in public, concise in private; reputed, but not proved to be a miser; at bottom, one of those economists who are readily prodigal at their own fancy or duty; lettered, but not very sensitive to letters; a gentleman, but not a chevalier; simple, calm, and strong; adored by his family and his household; a fascinating talker, an undeceived statesman, inwardly cold, dominated by immediate interest, always governing at the shortest range, incapable of rancor and of gratitude, making use without mercy of superiority on mediocrity, clever in getting parliamentary majorities to put in the wrong those mysterious unanimities which mutter dully under thrones; unreserved, sometimes imprudent in his lack of reserve, but with marvellous address in that imprudence; fertile in expedients, in countenances, in masks; making France fear Europe and Europe France!
