“You can neither lie to a neighbourhood park, nor reason with it. 'Artist's conceptions' and persuasive renderings can put pictures of life into proposed neighbourhood parks or park malls, and verbal rationalizations can conjure up users who ought to appreciate them, but in real life only diverse surroundings have the practical power of inducing a natural, continuing flow of life and use.”

“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. ”

“No neighbourhood or district, no matter how well established, prestigious or well heeled and no matter how intensely populated for one purpose, can flout the necessity for spreading people through time of day without frustrating its potential for generating diversity.”

“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.”

“[Public housing projects] are not lacking in natural leaders,' [Ellen Lurie, a social worker in East Harlem] says. 'They contain people with real ability, wonderful people many of them, but the typical sequence is that in the course of organization leaders have found each other, gotten all involved in each others' social lives, and have ended up talking to nobody but each other. They have not found their followers. Everything tends to degenerate into ineffective cliques, as a natural course. There is no normal public life. Just the mechanics of people learning what s going on is so difficult. It all makes the simplest social gain extra hard for these people.”

“Neighborhood is a word that has come to sound like a Valentine. As a sentimental concept, 'neighborhood' is harmful to city planning. It leads to attempts at warping city life into imitations of town or suburban life. Sentimentality plays with sweet intentions in place of good sense.”

“...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.”
