To what purpose all this, but to show that the difference so observable in men’s understandings and parts does not arise so much from the natural faculties as acquired habits? He would be laughed at that should go about to make a fine dancer out of a country hedger at past fifty. And he will not have much better success who shall endeavor at that age to make a man reason well, or speak handsomely, who has never been used to it, though you should lay before him a collection of all the best precepts of logic or oratory. Nobody is made anything by hearing of rules, or laying them up in his memory; practice must settle the habit of doing without reflecting on the rule; and you may as well hope to make a good painter, or musician, extempore, by a lecture and instruction in the arts of music and painting, as a coherent thinker, or strict reasoner, by a set of rules, showing him wherein right reasoning consists. This being so, that defects and weakness in men’s understandings, as well as other faculties, come from want of a right use of their own minds, I am apt to think the fault is generally mislaid upon nature, and there is often a complaint of want of parts, when the fault lies in want of a due improvement of them. We see men frequently dexterous and sharp enough in making a bargain, who if you reason with them about matters of religion appear perfectly stupid. THOUGHTS AND APHORISMS. By JONATHAN SWIFT. If the men of wit and genius would resolve never to complain in their works of critics and detractors, the next age would not know that they ever had any. Imaginary evils soon become real ones by indulging our reflections on them, as he who in a melancholy fancy sees something like a face on the wall or the wainscot can, by two or three touches with a lead pencil, make it look visible and agreeing with what he fancied. Men of great parts are often unfortunate in the management of public business, because they are apt to go out of the common road by the quickness of their imagination. This I once said to my Lord Bolingbroke, and desired he would observe that the clerks in his office used a sort of ivory knife with a blunt edge to divide a sheet of paper, which never failed to cut it even, only requiring a steady hand; whereas if they should make use of a sharp penknife, the sharpness would make it often go out of the crease and disfigure the paper. “He who does not provide for his own house,” St. Paul says, “is worse than an infidel;” and I think he who provides only for his own house is just equal with an infidel. I never yet knew a wag (as the term is) who was not a dunce. When we desire or solicit anything, our minds run wholly on the good side or circumstances of it; when it is obtained, our minds run wholly on the bad ones. The latter part of a wise man’s life is taken up in curing the follies, prejudices, and false opinions he had contracted in the former.
