People who try to predict the future by extrapolating in a line of more of what exists - they are always wrong.

Cities are an immense laboratory of trial and error, failure and success, in city building and city design.

I get absolutely ruthless in my own way about not doing anything else when I am trying to concentrate on writing a book. I have to stick to it and concentrate.

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.

Artists, whatever their medium, make selections from the abounding materials of life, and organize these selections into works that are under the control of the artist.... In relation to the inclusiveness and literally endless intricacy of life, art is arbitrary, symbolic and abstracted. That is its value and the source of its own kind of order and coherence.

In our American cities, we need all kinds of diversity.

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.
