“Every walker is a guard on patrol to protect the ineffable.”

“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.”

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

“...the gym is a kind of wildlife preserve for bodily exertion. A preserve protects species whose habitat is vanishing elsewhere, and the gym (and home gym) accommodates the survival of bodies after the abandonment of the original sites of bodily exertion.”

“I think one of the primary goals of a feminist landscape architecture would be to work toward a public landscape in which we can roam the streets at midnight, in which every square is available for Virginia Woolf to make up her novels ”

“Perhaps the central question about [Eliot] Porter's work is about the relationship between science, aesthetics, and environmental politics. His brother, the painter and critic Fairfield Porter, wrote in a 1960 review of [Porter's] colour photographs: 'There is no subject and background, every corner is alive,' and this suggests what an ecological aesthetic might look like. ”

“Movies are made out of darkness as well as light; it is the surpassingly brief intervals of darkness between each luminous still image that make it possible to assemble the many images into one moving picture. Without that darkness, there would only be a blur. Which is to say that a full-length movie consists of half an hour or an hour of pure darkness that goes unseen. If you could add up all the darkness, you would find the audience in the theater gazing together at a deep imaginative night. It is the terra incognita of film, the dark continent on every map. In a similar way, a runner’s every step is a leap, so that for a moment he or she is entirely off the ground. For those brief instants, shadows no longer spill out from their feet, like leaks, but hover below them like doubles, as they do with birds, whose shadows crawl below them, caressing the surface of the earth, growing and shrinking as their makers move nearer or farther from that surface. For my friends who run long distances, these tiny fragments of levitation add up to something considerable; by their own power they hover above the earth for many minutes, perhaps some significant portion of an hour or perhaps far more for the hundred-mile races. We fly; we dream in darkness; we devour heaven in bites too small to be measured.”
