Let it be your maxim through life, to know all you can know, yourself; and never to trust implicitly to the information of others.
Lord ChesterfieldCardinal Mazarin was a great knave, but no great man; much more cunning than able; scandalously false and dirtily greedy.
Lord ChesterfieldA certain degree of ceremony is a necessary outwork of manners, as well as of religion; it keeps the forward and petulant at a proper distance, and is a very small restraint to the sensible and to the well-bred part of the world.
Lord ChesterfieldLet your letter be written as accurately as you are able,--I mean with regard to language, grammar, and stops; for as to the matter of it the less trouble you give yourself the better it will be. Letters should be easy and natural, and convey to the persons to whom we send them just what we should say to the persons if we were with them.
Lord Chesterfield
