—If a logical mind ever found out anything with its logic?—I should say that its most frequent work was to build a pons asinorum over chasms which shrewd people can bestride without such a structure. You can hire logic, in the shape of a lawyer, to prove anything that you want to prove. You can buy treatises to show that Napoleon never lived, and that no battle of Bunker-hill was ever fought. The great minds are those with a wide span, which couple truths related to, but far removed from, each other. Logicians carry the surveyor’s chain over the track of which these are the true explorers. I value a man mainly for his primary relations with truth, as I understand truth,—not for any secondary artifice in handling his ideas. Some of the sharpest men in argument are notoriously unsound in judgment. I should not trust the counsel of a smart debater, any more than that of a good chess-player. Either may of course advise wisely, but not necessarily because he wrangles or plays well. The old gentleman who sits opposite got his hand up, as a pointer lifts his forefoot, at the expression, “his relations with truth, as I understand truth,” and when I had done, sniffed audibly, and said I talked like a transcendentalist. For his part, common sense was good enough for him. Precisely so, my dear sir, I replied; common sense, as you understand it. We all have to assume a standard of judgment in our own minds, either of things or persons. A man who is willing to take another’s opinion has to exercise his judgment in the choice of whom to follow, which is often as nice a matter as to judge of things for one’s self. On the whole, I had rather judge men’s minds by comparing their thoughts with my own, than judge of thoughts by knowing who utter them. I must do one or the other. It does not follow, of course, that I may not recognize another man’s thoughts as broader and deeper than my own; but that does not necessarily change my opinion, otherwise this would be at the mercy of every superior mind that held a different one. How many of our most cherished beliefs are like those drinking-glasses of the ancient pattern, that serve us well so long as we keep them in our hand, but spill all if we attempt to set them down! I have sometimes compared conversation to the Italian game of mora, in which one player lifts his hand with so many fingers extended, and the other gives the number if he can. I show my thought, another his; if they agree, well; if they differ, we find the largest common factor, if we can, but at any rate avoid disputing about remainders and fractions, which is to real talk what tuning an instrument is to playing on it.
