“Being human is itself difficult, and therefore all kinds of settlements (except dream cities) have problems. Big cities have difficulties in abundance, because they have people in abundance.”

“Cities have the capability of providing something for everybody, only because, and only when, they are created by everybody.”

“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.”

“Planners, architects of city design, and those they have led along with them in their beliefs are not consciously disdainful of the importance of knowing how things work. On the contrary, they have gone to great pains to learn what saints and sages of modern orthodox planning have said about how cities ought to work and what ought to be good for people and business in them. They take this with such devotion that when contradictory reality intrudes, threatening tho shatter their dearly won learning, they must shrug reality aside.”

“Dull, inert cities, it is true, do contain the seeds of their own destruction and little else. But lively, diverse, intense cities contain the seeds of their own regeneration, with energy enough to carry over for problems and needs outside themselves.”

“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.”
