When this is melted and dropped upon the letter, if _Dolly_ fumbles too long for her thimble, till the wax is over hardened, it will not receive the mark of her thimble from the usual impulse which was wont to imprint it. Very well. If _Dolly_’s wax, for want of better, is bees-wax, or of a temper too soft,—tho’ it may receive,—it will not hold the impression, how hard soever _Dolly_ thrusts against it; and last of all, supposing the wax good, and eke the thimble, but applied thereto in careless haste, as her Mistress rings the bell;——in any one of these three cases the print left by the thimble will be as unlike the prototype as a brass-jack. Now you must understand that not one of these was the true cause of the confusion in my uncle _Toby_’s discourse; and it is for that very reason I enlarge upon them so long, after the manner of great physiologists—to shew the world, what it did _not_ arise from. What it did arise from, I have hinted above, and a fertile source of obscurity it is,—and ever will be,—and that is the unsteady uses of words, which have perplexed the clearest and most exalted understandings. It is ten to one (at _Arthur_’s) whether you have ever read the literary histories of past ages;—if you have, what terrible battles, ’yclept logomachies, have they occasioned and perpetuated with so much gall and ink-shed,—that a good-natured man cannot read the accounts of them without tears in his eyes. Gentle critick! when thou hast weighed all this, and considered within thyself how much of thy own knowledge, discourse, and conversation has been pestered and disordered, at one time or other, by this, and this only:—What a pudder and racket in COUNCILS about χδια and υωοςασις; and in the SCHOOLS of the learned about power and about spirit;—about essences, and about quintessences;——about substances, and about space.——What confusion in greater THEATRES from words of little meaning, and as indeterminate a sense! when thou considerest this, thou wilt not wonder at my uncle _Toby_’s perplexities,—thou wilt drop a tear of pity upon his scarp and his counterscarp;—his glacis and his covered way;—his ravelin and his half- moon: ’Twas not by ideas,—by Heaven; his life was put in jeopardy by words. C H A P. XXVIII WHEN my uncle _Toby_ got his map of _Namur_ to his mind, he began immediately to apply himself, and with the utmost diligence, to the study of it; for nothing being of more importance to him than his recovery, and his recovery depending, as you have read, upon the passions and affections of his mind, it behoved him to take the nicest care to make himself so far master of his subject, as to be able to talk upon it without emotion.
