“Everyone is aware that tremendous numbers of people concentrate in city downtowns and that, if they did not, there would be no downtown to amount to anything--certainly not one with much downtown diversity.”

“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.”

“You can't rely on bringing people downtown, you have to put them there.”

“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.”

“To generate exuberant diversity in a city's streets and districts four conditions are indispensable:1. The district, and indeed as many of its internal parts as possible, must serve more than one primary function; preferably more than two...2. Most blocks must be short; that is, streets and opportunities to turn corners must be frequent.3. The district must mingle buildings that vary in age and condition, including a good proportion of old ones so that they vary in the economic yield they must produce. This mingling must be fairly close-grained.4. There must be a sufficiently dense concentration of people, for whatever purposes they may be there...”

“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.”

“The more successfully a city mingles everyday diversity of uses and users in its everyday streets, the more successfully, casually (and economically) its people thereby enliven and support well-located parks that can thus give back grace and delight to their neighborhoods instead of vacuity. ”
