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.
Lord ChesterfieldIf a man, notoriously and designedly, insults and affronts you, knock him down; but if he only injures you, your best revenge is to be extremely civil to him in your outward behaviour, though at the same time you counterwork him, and return him the compliment, perhaps with interest.
Lord ChesterfieldMen have various subjects in which they may excel, or at least would be thought to excel, and though they love to hear justice done to them where they know they excel, yet they are most and best flattered upon those points where they wish to excel and yet are doubtful whether they do or not.
Lord ChesterfieldGreat merit or great failings will make you respected or despised; but trifles, little attentions, mere nothings, either done or neglected, will make you either liked or disliked, in the general run of the world. Examine yourself, why you like such and such people and dislike such and such others; and you will find that those different sentiments proceed from very slight causes.
Lord ChesterfieldIn order to judge of the inside of others, study your own; for men in general are very much alike; and though one has one prevailing passion, and another has another, yet their operations are much the same; and whatever engages or disgusts, pleases or offends you, in others, will, mutatis mutandis, engage, disgust, please, or offend others, in you.
Lord Chesterfield
