If ever a man and his wife, or a man and his mistress, who pass nights as well as days together, absolutely lay aside all good breeding, their intimacy will soon degenerate into a coarse familiarity, infallibly productive of contempt or disgust.

At any age we must cherish illusions, consolatory or merely pleasant; in youth, they are omnipresent; in old age we must search for them, or even invent them. But with all that, boredom is their natural and inevitable accompaniment.

Character must be kept bright as well as clean.

You must be respectful and assenting, but without being servile and abject. You must be frank, but without indiscretion, and close, without being costive. You must keep up dignity of character, without the least pride of birth, or rank. You must be gay, within all the bounds of decency and respect; and grave, without the affectation of wisdom, which does not become the age of twenty. You must be essentially secret, without being dark and mysterious. You must be firm, and even bold, but with great seeming modesty.

To write anything tolerable, the mind must be in a natural, proper disposition; provocatives, in that case, as well as in another,will only produce miserable, abortive performances.

Two people cannot be alone together for upwards of half an hour without one emerging as the superior.

Talk often, but never long; in that case, if you do not please, at least you are sure not to tire your hearers. Pay your own reckoning, but do not treat the whole company; this being one of the few cases in which people do not care to be treated, every one being fully convinced that he has wherewithal to pay.
