Christianity spread first along the great roads that led to Rome, as every free and natural current of thought did, owing to the circumstances of the period, and from the center was distributed to the outlying parts of the Empire. The skyline of New York is a monument of a splendor that no pyramids or palaces will ever equal or approach. But America's skyscrapers were not built by public funds nor for a public purpose; they were built by the energy, initiative and wealth of private individuals for personal profit. There is something a bit touching about urban experts these days. It does not occur to them that the city has outlived its evolutionary role, that the evidences of its demise are crystal clear around us, and that it is beyond help. To search for the ideal city today is useless. For all cities are different. Each one has its own spirit, own problems, and own pattern of life.
