“A procession is a participants' journey, while a parade is a performance with an audience.”

“A lone walker is both present and detached, more than an audience but less than a participant. Walking assuages or legitimizes this alienation.”

“The process of transformation consists mostly of decay.”

“A labyrinth is a symbolic journey . . . but it is a map we can really walk on, blurring the difference between map and world.”

“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.”

“In her novel Regeneration, Pat Barker writes of a doctor who 'knew only too well how often the early stages of change or cure may mimic deterioration. Cut a chrysalis open, and you will find a rotting caterpillar. What you will never find is that mythical creature, half caterpillar, half butterfly, a fit emblem of the human soul, for those whose cast of mind leads them to seek such emblems. No, the process of transformation consists almost entirely of decay.”

“Many people nowadays live in a series of interiors...disconnected from each other. On foot everything stays connected, for while walking one occupies the spaces between those interiors in the same way one occupies those interiors. One lives in the whole world rather than in interiors built up against it.”
