‘Les manieres nobles et aisees, la tournure d’un homme de condition, le ton de la bonne compagnie, les graces, le jeune sais quoi, qui plait’, are as necessary to adorn and introduce your intrinsic merit and knowledge, as the polish is to the diamond; which, without that polish, would never be worn, whatever it might weigh. Do not imagine that these accomplishments are only useful with women; they are much more so with men. In a public assembly, what an advantage has a graceful speaker, with genteel motions, a handsome figure, and a liberal air, over one who shall speak full as much good sense, but destitute of these ornaments? In business, how prevalent are the graces, how detrimental is the want of them? By the help of these I have known some men refuse favors less offensively than others granted them. The utility of them in courts and negotiations is inconceivable. You gain the hearts, and consequently the secrets, of nine in ten, that you have to do with, in spite even of their prudence; which will, nine times in ten, be the dupe of their hearts and of their senses. Consider the importance of these things as they deserve, and you will not lose one minute in the pursuit of them.
You are traveling now in a country once so famous both for arts and arms, that (however degenerate at present) it still deserves your attention and reflection. View it therefore with care, compare its former with its present state, and examine into the causes of its rise and its decay. Consider it classically and politically, and do not run through it, as too many of your young countrymen do, musically, and (to use a ridiculous word) KNICK-KNACKICALLY. No piping nor fiddling, I beseech you; no days lost in poring upon almost imperceptible ‘intaglios and cameos’: and do not become a virtuoso of small wares. Form a taste of painting, sculpture, and architecture, if you please, by a careful examination of the works of the best ancient and modern artists; those are liberal arts, and a real taste and knowledge of them become a man of fashion very well. But, beyond certain bounds, the man of taste ends, and the frivolous virtuoso begins.
Your friend Mendes, the good Samaritan, dined with me yesterday. He has more good-nature and generosity than parts. However, I will show him all the civilities that his kindness to you so justly deserves. He tells me that you are taller than I am, which I am very glad of: I desire that you may excel me in everything else too; and, far from repining, I shall rejoice at your superiority. He commends your friend Mr. Stevens extremely; of whom too I have heard so good a character from other people, that I am very glad of your connection with him. It may prove of use to you hereafter. When you meet with such sort of Englishmen abroad, who, either from their parts or their rank, are likely to make a figure at home, I would advise you to cultivate them, and get their favorable testimony of you here, especially those who are to return to England before you. Sir Charles Williams has puffed you (as the mob call it) here extremely. If three or four more people of parts do the same, before you come back, your first appearance in London will be to great advantage. Many people do, and indeed ought, to take things upon trust; many more do, who need not; and few dare dissent from an established opinion. Adieu!
