“A border--the perimeter of a single massive or stretched-out use of territory--forms the edge of an area of 'ordinary' city. Often borders are thought of as passive objects, or matter-of-factly just as edges. However, a border exerts an active influence.”

“I tis hopeless to try to convert some borders into seams. Expressways and their ramps are examples. Moreover, even in the case of large parks, campuses or waterfronts, the barrier effects can likely be overcome well only along portions of perimeters.”

“There is a widespread belief that americans hate cities. I think it is probable that Americans hate city failure, but, from the evidence, we certainly do not hate successful and vital city areas. On the contrary, so many people want to make use of such places, so many people want to work in them or live in them or visit in them, that municipal self-destruction ensues. In killing successful diversity combinations with money, we are employing perhaps our nearest equivalent to killing with kindness.”

“Automobiles are often conveniently tagged as the villains responsible for the ills of cities and the disappointments and futilities of city planning. But the destructive effect of automobiles are much less a cause than a symptom of our incompetence at city building.”

“I have been dwelling upon downtowns. This is not because mixtures of primary uses are unneeded elsewhere in cities. On the contrary they are needed, and the success of mixtures downtown (on in the most intensive portions of cities, whatever they are called) is related to the mixture possible in other part of cities.”

“Under the seeming disorder of the old city, wherever the old city is working successfully, is a marvelous order for maintaining the safety of the streets and the freedom of the city. It is a complex order. Its essence is intricacy of sidewalk use, bringing with it a constant succession of eyes. This order is all composed of movement and change, and although it is life, not art, we may fancifully call it the art form of the city and liken it to the dance — not to a simple-minded precision dance with everyone kicking up at the same time, twirling in unison and bowing off en masse, but to an intricate ballet in which the individual dancers and ensembles all have distinctive parts which miraculously reinforce each other and compose an orderly whole. The ballet of the good city sidewalk never repeats itself from place to place, and in any once place is always replete with new improvisations.”

“...frequent streets and short blocks are valuable because of the fabric of intricate cross-use that they permit among the users of a city neighbouhood.”
