We used sometimes to walk over the Brooklyn Bridge, that song in stone and steel of an engineer who was also a great artist, at dusk, when the tides of shadow flood in from the lower bay to break in a surf of glory and mystery and illusion against the tall towers of Manhattan. Seen from the middle arch of the bridge at twilight, New York with its girdle of shifting waters and its drift of purple cloud and its quick pulsations of unstable light is a miracle of splendor and beauty that lights up the heart like the laughter of a god. But, descend. Go down into the city. Mingle with the details. The dirty old shed from which the "L" trains and trolleys put out with their jammed and mangled thousands for flattest Flatbush and the unknown bourne of ulterior Brooklyn is still the same dirty old shed; on a hot, damp night the pasty streets stink like a paperhanger's overalls; you are trodden and over-ridden by greasy little profiteers and their hopping victims; you are encompassed round about by the ugly and the sordid, and the objectionable is exuded upon you from a myriad candid pores; your elation and your illusion vanish like ingenuous snowflakes that have kissed a hot dog sandwich on its fiery brow, and you say: "Beauty? Aw, h--l! What's the use?" And yet you have seen beauty. And beauty that was created by these people and people like these.... You have seen the tall towers of Manhattan, wonderful under the stars. How did it come about that such growths came from such soil--that a breed lawless and sordid and prosaic has written such a mighty hieroglyphic against the sky? This glamor out of a pigsty ... how come? How is it that this hideous, half-brute city is also beautiful and a fit habitation for demi-gods? How come? It comes about because the wise and subtle deities permit nothing worthy to be lost. It was with no thought of beauty that the builders labored; no conscious thought; they were masters or slaves in the bitter wars of commerce, and they never saw as a whole what they were making; no one of them did. But each one had had his dream. And the baffled dreams and the broken visions and the ruined hopes and the secret desires of each one labored with him as he labored; the things that were lost and beaten and trampled down went into the stone and steel and gave it soul; the aspiration denied and the hope abandoned and the vision defeated were the things that lived, and not the apparent purpose for which each one of all the millions sweat and toiled or cheated; the hidden things, the silent things, the winged things, so weak they are easily killed, the unacknowledged things, the rejected beauty, the strangled appreciation, the inchoate art, the submerged spirit--these groped and found each other and gathered themselves together and worked themselves into the tiles and mortar of the edifice and made a town that is a worthy fellow of the sunrise and the sea winds. Humanity triumphs over its details.
