Chamfort records that M. de Lassay, a mild man who knew high society well, said one should swallow a toad every morning so that nothing else would seem disgusting for the rest of a day spent in the world. The anecdote presents daily participation in polite society as a series of humiliations that can only be endured by numbing oneself in advance.
Chamfort holds that anyone who lives among people and sees them clearly faces only two outcomes: the heart breaks, or it hardens to bronze. Sustained exposure to vanity and self-interest leaves no stable middle position of open-hearted clear sight. You either suffer continuously or you armor yourself, and the armor is itself a moral loss.
Chamfort divides society into two great classes: those who have more dinners than appetite, and those who have more appetite than dinners. Social order is a mismatch between who holds the resources and who has the need or drive for them. The satiated control access, and the hungry must court them to get it, and this structure produces the whole economy of flattery.
When a benefit can be withdrawn at will, the dependant must keep performing gratitude and agreement, so over time his judgment turns into a courtier's reflex. The patron in turn hears only flattery and loses access to the truth, and he comes to treat his generosity as a claim on the other's soul. Both sides are degraded by the same transaction, which is why Chamfort ranks justice above generosity.
Chamfort treats salon esteem as a matter of costume: there are well-dressed follies just as there are well-dressed fools. Read social standing this way and you see that manner, connections and fluency are what get rewarded, while merit is incidental. Fashionable opinion then shows you who has mastered the performance, not who is right.
