Book excerpt: First Published in 1991. Knowing any real city, and still more so, knowing what it is to know a city, may be as much about passive as about active experience. What we read in the field-that field of the city in all its bizarre mixture of culture and nature-is bound to determine, to some non-fictional extent, what we know of it, what we imagine it could be, what we fear it may be, or become. These essays are meant to be, albeit in their critical mode, the recountings of knowing something through something else: they are the projected imagination, through reading, of the reading by the self and/or others (a wide range of each) of a city, or cities as such, of what city-knowing or city-thinking is. The city as stage, market, and labyrinth, variously trafficked and aestheticized, dreamt and politicized, as passionately written by authors from Cicero to Kazin, from Wordsworth, Dickens, Whitman, and Woolf, to Williams, Ashbery, and Bonnefoy, is the place the essays play themselves out, through architecture and metaphor.
