The theatre avails itself of the best talent of poet, of painter, and of amateur of taste, to make the _ensemble_ of dramatic effect. The marine insurance office has its mathematical counsellor to settle averages; the life-assurance, its table of annuities. The wine-merchant has his analyst and taster, the more exquisite the better. He has also, I fear, his debts to the chemist as well as to the vineyard. Our modern wealth stands on a few staples, and the interest nations took in our war was exasperated by the importance of the cotton trade. And what is cotton? One plant out of some two hundred thousand known to the botanist, vastly the larger part of which are reckoned weeds. What is a weed? A plant whose virtues have not yet been discovered,—every one of the two hundred thousand probably yet to be of utility in the arts. As Bacchus of the vine, Ceres of the wheat, as Arkwright and Whitney were the demi-gods of cotton, so prolific Time will yet bring an inventor to every plant. There is not a property in Nature but a mind is born to seek and find it. For it is not the plants or the animals, innumerable as they are, nor the whole magazine of material nature that can give the sum of power, but the infinite applicability of these things in the hands of thinking man, every new application being equivalent to a new material.[228] Our sleepy civilization, ever since Roger Bacon and Monk Schwartz invented gunpowder, has built its whole art of war, all fortification by land and sea, all drill and military education, on that one compound,—all is an extension of a gun-barrel,—and is very scornful about bows and arrows, and reckons Greeks and Romans and Middle Ages little better than Indians and bow-and-arrow times. As if the earth, water, gases, lightning and caloric had not a million energies, the discovery of any one of which could change the art of war again, and put an end to war by the exterminating forces man can apply. Now, if this is true in all the useful and in the fine arts, that the direction must be drawn from a superior source or there will be no good work, does it hold less in our social and civil life? In our popular politics you may note that each aspirant who rises above the crowd, however at first making his obedient apprenticeship in party tactics, if he have sagacity, soon learns that it is by no means by obeying the vulgar weathercock of his party, the resentments, the fears and whims of it, that real power is gained, but that he must often face and resist the party, and abide by his resistance, and put them in fear; that the only title to their permanent respect, and to a larger following, is to see for himself what is the real public interest, and to stand for that;—that is a principle, and all the cheering and hissing of the crowd must by and by accommodate itself to it. Our times easily afford you very good examples.
