One principal topic of our conversation will be, not only the purity but the elegance of the English language; in both which you are very deficient. Another will be the constitution of this country, of which, I believe, you know less than of most other countries in Europe. Manners, attentions, and address, will also be the frequent subjects of our lectures; and whatever I know of that important and necessary art, the art of pleasing. I will unreservedly communicate to you. Dress too (which, as things are, I can logically prove, requires some attention) will not always escape our notice. Thus, my lectures will be more various, and in some respects more useful than Professor Mascow's, and therefore, I can tell you, that I expect to be paid for them; but, as possibly you would not care to part with your ready money, and as I do not think that it would be quite handsome in me to accept it, I will compound for the payment, and take it in attention and practice.
Pray remember to part with all your friends, acquaintances, and mistresses, if you have any at Paris, in such a manner as may make them not only willing but impatient to see you there again. Assure them of your desire of returning to them; and do it in a manner that they may think you in earnest, that is 'avec onction et une espece d'attendrissement'. All people say, pretty near the same things upon those occasions; it is the manner only that makes the difference; and that difference is great. Avoid, however, as much as you can, charging yourself with commissions, in your return from hence to Paris; I know, by experience, that they are exceedingly troublesome, commonly expensive, and very seldom satisfactory at last, to the persons who gave them; some you cannot refuse, to people to whom you are obliged, and would oblige in your turn; but as to common fiddle-faddle commissions, you may excuse yourself from them with truth, by saying that you are to return to Paris through Flanders, and see all those great towns; which I intend you shall do, and stay a week or ten days at Brussels. Adieu! A good journey to you, if this is my last; if not, I can repeat again what I shall wish constantly.
LETTER CLIII
LONDON, December 19, O. S. 1751-[Note the date, which indicates that the sojourn with the author has ended.]
MY DEAR FRIEND: You are now entered upon a scene of business, where I hope you will one day make a figure. Use does a great deal, but care and attention must be joined to it. The first thing necessary in writing letters of business, is extreme clearness and perspicuity; every paragraph should be so clear and unambiguous, that the dullest fellow in the world may not be able to mistake it, nor obliged to read it twice in order to understand it. This necessary clearness implies a correctness, without excluding an elegance of style. Tropes, figures, antitheses, epigrams, etc., would be as misplaced and as impertinent in letters of business, as they are sometimes (if judiciously used) proper and pleasing in familiar letters, upon common and trite subjects. In business, an elegant simplicity, the result of care, not of labor, is required. Business must be well, not affectedly dressed; but by no means negligently. Let your first attention be to clearness, and read every paragraph after you have written it, in the critical view of discovering whether it is possible that any one man can mistake the true sense of it: and correct it accordingly.
Our pronouns and relatives often create obscurity or ambiguity; be therefore exceedingly attentive to them, and take care to mark out with precision their particular relations. For example, Mr. Johnson acquainted me that he had seen Mr. Smith, who had promised him to speak to Mr. Clarke, to return him (Mr. Johnson) those papers, which he (Mr. Smith) had left some time ago with him (Mr. Clarke): it is better to repeat a name, though unnecessarily, ten times, than to have the person mistaken once. WHO, you know, is singly relative to persons, and cannot be applied to things; WHICH and THAT are chiefly relative to things, but not absolutely exclusive of persons; for one may say, the man THAT robbed or killed such-a-one; but it is better to say, the man WHO robbed or killed. One never says, the man or the woman WHICH. WHICH and THAT, though chiefly relative to things, cannot be always used indifferently as to things, and the 'euoovca' must sometimes determine their place. For instance, the letter WHICH I received from you, WHICH you referred to in your last, WHICH came by Lord Albemarle's messenger WHICH I showed to such-a-one; I would change it thus-The letter THAT I received from you; WHICH you referred to in your last, THAT came by Lord Albemarle's messenger, and WHICH I showed to such-a-one.
