Redundancy Is Expensive But Indispensable.

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.

Streets And Their Sidewalks-the Main Public Places Of A City-are Its Most Vital Organs.

Cities Never Flourish Alone. They Have To Be Trading With Other Cities. My New Hypothesis Shows Why. But Also In Trading With Each Other They Can't Be In Too Different Stages Of Development, And They Can't Copy One Another.

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.

Americans Don't Really Think That Other Places Are As Real As America.
