It might be, somewhat overhardily, advanced that there is no such thing as positive fact, but only relative fact. The mind, in an instinctive perception of this hazardous truth, clings to contrast as the only basis of inference, and in now taking my tenth or twentieth look at London I have been careful to keep about me a pocket vision of New York, so as to see what London is like by making constantly sure what it is not like. A pocket vision, say, of Paris, would not serve the same purpose. That is a city of a legal loveliness, of a beauty obedient to a just municipal control, of a grandeur studied and authorized in proportion and relation to the design of a magnificent entirety; it is a capital nobly realized on lines nobly imagined. But New York and London may always be intelligibly compared because they are both the effect of an indefinite succession of anarchistic impulses, sometimes correcting and sometimes promoting, or at best sometimes annulling one another. Each has been mainly built at the pleasure of the private person, with the community now and then swooping down upon him, and turning him out of house and home to the common advantage. Nothing but our racial illogicality has saved us from the effect of our racial anarchy in the social structure as well as the material structure, but if we could see London and New York as lawless in the one way as in the other, we should perhaps see how ugly they collectively are. The sum of such involuntary reflection with me has been the perception that London was and is and shall be, and New York is and shall be, but has hardly yet been. New York is therefore one-third less morally, as she is one-third less numerically, than London. In her future she has no past, but only a present to retrieve; though perhaps a present like hers is enough. She is also one less architecturally than London; she is two-thirds as splendid, as grand, as impressive. In fact, if I more closely examine my pocket vision, I am afraid that I must hedge from this modest claim, for we have as yet nothing to compare with at least a half of London magnificence, whatever we may have in the seventeen or eighteen hundred years that shall bring us of her actual age. As we go fast in all things, we may then surpass her; but this is not certain, for in her more deliberate way she goes fast, too. In the mean time the materials of comparison, as they lie dispersed in the pocket vision, seem few. The sky-scrapers, Brooklyn Bridge, Madison Square Garden, and some vast rocketing hotels offer themselves rather shrinkingly for the contrast with those miles of imperial and municipal architecture which in London make you forget the leagues of mean little houses, and remember the palaces, the law-courts, the great private mansions, the dignified and shapely flats, the large department stores, the immense hotels, the bridges, the monuments of every kind.
