This dignity of manners, which I recommend so much to you, is not only as different from pride, as true courage is from blustering, or true wit from joking; but is absolutely inconsistent with it; for nothing vilifies and degrades more than pride. The pretensions of the proud man are oftener treated with sneer and contempt, than with indignation; as we offer ridiculously too little to a tradesman, who asks ridiculously too much for his goods; but we do not haggle with one who only asks a just and reasonable price.

Abject flattery and indiscriminate assentation degrade as much as indiscriminate contradiction and noisy debate disgust. But a modest assertion of one’s own opinion, and a complaisant acquiescence to other people’s, preserve dignity.

Vulgar, low expressions, awkward motions and address, vilify, as they imply either a very low turn of mind, or low education and low company.

Frivolous curiosity about trifles, and a laborious attention to little objects which neither require nor deserve a moment’s thought, lower a man; who from thence is thought (and not unjustly) incapable of greater matters. Cardinal de Retz, very sagaciously, marked out Cardinal Chigi for a little mind, from the moment that he told him he had wrote three years with the same pen, and that it was an excellent good one still.

The PG Edition of Chesterfield’s Letters to His Son — Part 138

A certain degree of exterior seriousness in looks and motions gives dignity, without excluding wit and decent cheerfulness, which are always serious themselves. A constant smirk upon the face, and a whifing activity of the body, are strong indications of futility. Whoever is in a hurry, shows that the thing he is about is too big for him. Haste and hurry are very different things.

I have only mentioned some of those things which may, and do, in the opinion of the world, lower and sink characters, in other respects valuable enough,--but I have taken no notice of those that affect and sink the moral characters. They are sufficiently obvious. A man who has patiently been kicked may as well pretend to courage, as a man blasted by vices and crimes may to dignity of any kind. But an exterior decency and dignity of manners will even keep such a man longer from sinking, than otherwise he would be: of such consequence is the [****], even though affected and put on! Pray read frequently, and with the utmost attention, nay, get by heart, if you can, that incomparable chapter in Cicero’s “Offices,” upon the [****], or the Decorum. It contains whatever is necessary for the dignity of manners.
