Letters to His Son on the Art of Becoming a Man of the World and a Gentleman (Письма к сыну – полный вариант)

Your dress (as insignificant a thing as dress is in itself) is now become an object worthy of some attention; for, I confess, I cannot help forming some opinion of a man's sense and character from his dress; and I believe most people do as well as myself. Any affectation whatsoever in dress implies, in my mind, a flaw in the understanding. Most of our young fellows here display some character or other by their dress; some affect the tremendous, and wear a great and fiercely cocked hat, an enormous sword, a short waistcoat and a black cravat; these I should be almost tempted to swear the peace against, in my own defense, if I were not convinced that they are but meek asses in lions' skins. Others go in brown frocks, leather breeches, great oaken cudgels in their hands, their hats uncocked, and their hair unpowdered; and imitate grooms, stage-coachmen, and country bumpkins so well in their outsides, that I do not make the least doubt of their resembling them equally in their insides. A man of sense carefully avoids any particular character in his dress; he is accurately clean for his own sake; but all the rest is for other people's. He dresses as well, and in the same manner, as the people of sense and fashion of the place where he is. If he dresses better, as he thinks, that is, more than they, he is a fop; if he dresses worse, he is unpardonably negligent. But, of the two, I would rather have a young fellow too much than too little dressed; the excess on that side will wear off, with a little age and reflection; but if he is negligent at twenty, he will be a sloven at forty, and stink at fifty years old. Dress yourself fine, where others are fine; and plain where others are plain; but take care always that your clothes are well made, and fit you, for otherwise they will give you a very awkward air. When you are once well dressed for the day think no more of it afterward; and, without any stiffness for fear of discomposing that dress, let all your motions be as easy and natural as if you had no clothes on at all. So much for dress, which I maintain to be a thing of consequence in the polite world.

As to manners, good-breeding, and the Graces, I have so often entertained you upon those important subjects, that I can add nothing to what I have formerly said. Your own good sense will suggest to you the substance of them; and observation, experience, and good company, the several modes of them. Your great vivacity, which I hear of from many people, will be no hindrance to your pleasing in good company: on the contrary, will be of use to you, if tempered by good-breeding and accompanied by the Graces. But then, I suppose your vivacity to be a vivacity of parts, and not a constitutional restlessness; for the most disagreeable composition that I know in the world, is that of strong animal spirits, with a cold genius. Such a fellow is troublesomely active, frivolously busy, foolishly lively; talks much with little meaning, and laughs more, with less reason whereas, in my opinion, a warm and lively genius with a cool constitution, is the perfection of human nature.

Do what you will at Berlin, provided you do but do something all day long. All that I desire of you is, that you will never slattern away one minute in idleness and in doing of nothing. When you are (not) in company, learn what either books, masters, or Mr. Harte, can teach you; and when you are in company, learn (what company can only teach you) the characters and manners of mankind. I really ask your pardon for giving you this advice; because, if you are a rational creature and thinking being, as I suppose, and verily believe you are, it must be unnecessary, and to a certain degree injurious. If I did not know by experience, that some men pass their whole time in doing nothing, I should not think it possible for any being, superior to Monsieur Descartes' automatons, to squander away, in absolute idleness, one single minute of that small portion of time which is allotted us in this world.
