THE PASSIONS.--Whenever you would persuade or prevail, address yourself to the passions; it is by them that mankind is to be taken. Cæsar bade his soldiers, at the battle of Pharsalia, aim at the faces of Pompey’s men; they did so, and prevailed. I bid you strike at the passions; and if you do, you, too, will prevail. If you can once engage people’s pride, love, pity, ambition (or whichever is their prevailing passion) on your side, you need not fear what their reason can do against you. [_Same date._] MY DEAR BOY:-- “Sunt quibus in Satirâ videar nimis acer.” I find, sir, you are one of those; though I cannot imagine why you think so, unless something that I have said, very innocently, has happened to be very applicable to somebody or other of your acquaintance. He makes the satire, who applies it, _qui capit ille facit_. I hope you do not think I meant you, by anything I have said; because, if you do, it seems to imply a consciousness of some guilt, which I dare not presume to suppose, in your case. I know my duty too well, to express, and your merit too well to entertain, such a suspicion. I have not lately read the satirical authors you mention, having very little time here to read. [_Dublin, February, 1746._] INATTENTION.--There is no surer sign in the world of a little, weak mind, than inattention. Whatever is worth doing at all is worth doing well; and nothing can be done well without attention. It is the sure answer of a fool, when you ask him about anything that was said or done where he was present, that “truly he did not mind it.” And why did not the fool mind it? What had he else to do there, but to mind what was doing? A man of sense sees, hears, and retains everything that passes where he is. I desire I may never hear you talk of not minding, nor complain, as most fools do, of a treacherous memory. Mind, not only what people say, but how they say it; and, if you have any sagacity, you may discover more truth by your eyes than by your ears. People can say what they will, but they cannot look what they will, and their looks frequently discover what their words are calculated to conceal. The most material knowledge of all--I mean the knowledge of the world--is not to be acquired without great attention. [_Feb. 26, 1746._]
