The Duc de Saint-Simon resided for many years at Versailles. He left an account of Life there
His natural talents were below mediocrity; but he had a mind capable of improvement, of receiving polish, of assimilating what was best in the minds of others without slavish imitation; and he profited greatly throughout his life from having associated with the ablest and wittiest persons, of both sexes, and of various stations. He entered the world … at a fortunate moment, for men of distinction abounded.
… Glory was his passion, but he also liked order and regularity in all things; he was naturally prudent, moderate, and reserved; always master of his tongue and his emotions. Will it be believed? he was also naturally kind-hearted and just.
