We must, of course, understand _usefulness_ in its widest sense; otherwise we should be looking at the world in a manner too little utilitarian, not too much so. Houses and furniture and utensils, clothes, tools and weapons, must undoubtedly exemplify utility first and foremost because they serve our life in the most direct, indispensable and unvarying fashion, always necessary and necessary to everyone. But once these universal unchanging needs supplied, a great many others become visible: needs to the individual or to individuals and races under definite and changing circumstances. The sonnet or the serenade are useful to the romantic lover in the same manner that carriage-horses and fine clothes are useful to the man who woos more practically-minded ladies. The diamonds of a rich woman serve to mark her status quite as much as to please the unpleasable eye of envy; in the same way that the uniform, the robes and vestments, are needed to set aside the soldier, the magistrate or priest, and give him the right of dealing _ex officio_, not as a mere man among men. And the consciousness of such apparent superfluities, whether they be the expression of wealth or of hierarchy, of fashion or of caste, gives to their possessor that additional self-importance which is quite as much wanted by the ungainly or diffident moral man as the additional warmth of his more obviously needed raiment is by the poor, chilly, bodily human being. I will not enlarge upon the practical uses which recent ethnology has discovered in the tattooing, the painting, the masks, headdresses, feather skirts, cowries and beads, of all that elaborate ornamentation with which, only a few years back, we were in the habit of reproaching the poor, foolish, naked savages; additional knowledge of their habits having demonstrated rather our folly than theirs, in taking for granted that any race of men would prefer ornament to clothes, unless, as was the case, these ornaments were really more indispensable in their particular mode of life. For an ornament which terrifies an enemy, propitiates a god, paralyses a wild beast, or gains a wife, is a matter of utility, not of aesthetic luxury, so long as it happens to be efficacious, or so long as its efficacy is believed in. Indeed, the gold coach and liveried trumpeters of the nostrum vendor of bygone days, like their less enlivening equivalents in many more modern professions, are of the nature of trade tools, although the things they fashion are only the foolish minds of possible customers.
