We see instantly the beauty and richness of great architecture and city planning; we understand instantly the contribution of foreign cultures to the glorious complexity of life. But when you look at the great Cathedrals, Mosques, and grand boulevards of Europe, do you see also the laborers, their blood and toil, the hovels in which they take their tea? The wanderer sees the world in balance, a blend of light and dark, just like the photographer.

(It is said that Bernini, in designing Piazza San Pietro in Vatican City, wanted to emphasize the contrast between the grandiose piazza and the narrow and clogged streets of the working class neighborhood just outside, where the traveler would be first confronted by wet laundry whipping to and fro, children howling, the clack and clatter of everyday life, then, suddenly, be surprised and awed by the openness and grandeur of his famous piazza. Then Mussolini tore down the little houses and installed the wide and lifeless Via della Conciliazione. The balance is now lost.)
