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.

Some men tend to cling to old intellectual excitements, just as some belles, when they are old ladies, still cling to the fashions and coiffures of their exciting youth.

I think that things are going to change just because people get too damn bored with what they have.

The entrepreneurial investors of the time just want to repeat themselves indefinitely and don't know when to stop. You can't do that. And so finally the housing boom, or the auto boom, or whatever it is that's been carrying things along, runs out of customers.

Intricate minglings of different uses in cities are not a form of chaos. On the contrary, they represent a complex and highly developed form of order.

You don't get new products and services out of sameness.

(The psuedoscience of planning seems almost neurotic in its determination to imitate empiric failure and ignore empiric success.)
