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 ChesterfieldThe greatest powers cannot injure a man's character whose reputation is unblemished among his party.
Lord ChesterfieldSecond-rate knowledge, and middling talents, carry a man farther at courts, and in the busy part of the world, than superior knowledge and shining parts.
Lord ChesterfieldA learned parson, rusting in his cell at Oxford or Cambridge, will reason admirably well upon the nature of man; will profoundly analyze the head, the heart, the reason, the will, the passions, the senses, the sentiments, and all those subdivisions of we know not what ; and yet, unfortunately, he knows nothing of man... He views man as he does colours in Sir Isaac Newton's prism, where only the capital ones are seen; but an experienced dyer knows all their various shades and gradations, together with the result of their several mixtures.
