“In great cities, spaces as well as places are designed and built: walking, witnessing, being in public, are as much part of the design and purpose as is being inside to eat, sleep, make shoes or love or music. The word citizen has to do with cities, and the ideal city is organized around citizenship -- around participation in public life.”

“Cities have always offered anonymity, variety, and conjunction, qualities best basked in by walking: one does not have to go into the bakery or the fortune-teller's, only to know that one might. A city always contains more than any inhabitant can know, and a great city always makes the unknown and the possible spurs to the imagination.”

“Walkers are 'practitioners of the city,' for the city is made to be walked. A city is a language, a repository of possibilities, and walking is the act of speaking that language, of selecting from those possibilities. Just as language limits what can be said, architecture limits where one can walk, but the walker invents other ways to go.”

“Las Vegas suggests that the thirst for places, for cities and gardens and wilderness, is unslaked, that people will still seek out the experience of wandering about in the open air to examine the architecture, the spectacles, and the stuff for sale, will still hanker after surprises and strangers. That the city as a whole is one of the most pedestrian-unfriendly places in the world suggests something of the problems to be faced, but that its attraction is a pedestrian oasis suggests the possibility of recovering the spaces in which walking is viable.”

“One of the functions of landscape it to correspond to, nurture, and provoke exploration of the landscape of the imagination. Space to walk is also space to think, and I think that's one thing landscapes give us: places to think longer, more uninterrupted thoughts or thoughts to a rhythm other than the staccato of navigating the city.”

“Musing takes place in a kind of meadowlands of the imagination, a part of the imagination that has not yet been plowed, developed, or put to any immediately practical use. [--] [T]ime spent there is not work time, yet without that time the mind becomes sterile, dull, domesticated. The fight for free space—for wilderness and for public space—must be accompanied by a fight for free time to spend wandering in that space.”

“Italian cities have long been held up as ideals, not least by New Yorkers and Londoners enthralled by the ways their architecture gives beauty and meaning to everyday acts.”
