Zoning for diversity As production becomes increasingly clean and knowledge-based, as our urban economies tip dramatically to service industries, as racism and ethnic animosities ebb, and as the model of mixed use becomes more and more persuasive and visible, cities are in a position to dramatically rethink zoning as a medium for leveraging and usefully complicating difference, rather than simply isolating it.

Bridges as walls The biographer of Robert Moses, Robert A. Caro, refers to the bridges and underpasses of the famed New York State parkways. These bridges and underpasses are quite low, intentionally specified by Moses to allow only private cars to pass. All those who traveled by bus because they were poor or black or both were barred from the use and enjoyment of the parkland and its "public amenities" by the technical design of the bridges. Even at the time of Robert Moses, a political statement of the form "We don't want them blacks in our parks" would have been unacceptable in New York State. But a technological expression of the same prejudice appeared to be all right. Of course, to the public the intent of the design became evident only after it was executed, and then the bridges were there. Ursula M.

Michaelangelo's hammer A young man named Michelangelo stands in front of a huge granite monolith. He stands there at a time in history before the technologies that brought us the hammer and chisel have occurred. He gazes at the rock. He dreams his dream and the best that he is able to say is, What a wonderful stone you are. … Michaelangelo now stands in front of the same rock. Thrust into his hands are a hammer in one and a chisel in the other. He looks at his hands, at the technological tools that they hold, and gazing at the same stone, with epiphanic zeal, says I must let Moses out.
