In one of the famous "Letters to His Son" he writes: "Moral virtues are the foundation of society in general, and of friendship in particular; but attentions, manners, and graces, both adorn and strengthen them." Again he says: "Great merit, or great failings, will make you respected or despised; but trifles, little attentions, mere nothings, either done or reflected, will make you either liked or disliked, in the general run of the world."
