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.
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.
Pay attention now:
No matter how much you know or learn about syntax, grammar, or rhetoric,
This small internal quaver, this inner disturbance,
Is the most useful evidence you'll ever get.
Someday, you'll be able to articulate what causes it.
But for now, what's important is to notice it.
Noticing is always the goal.
...the faint vertigo caused by an ambiguity you can't quite detect.
What matter is what it points to.
Find out what's causing it and fix it
Even if you're not sure how.
