Brasilia is interesting only insofar as it was an entire High Modernist planned city. In most places, the Modernists rarely got their hands on entire cities at once. They did build a number of suburbs, neighborhoods, and apartment buildings. There was, however, a disconnect. Most people did not want to buy a High Modernist house or live in a High Modernist neighborhood. Most governments did want to fund High Modernist houses and neighborhoods, because the academics influencing them said it was the modern scientific rational thing to do. So in the end, one of High Modernists’ main contributions to the United States was the projects – ie government-funded public housing for poor people who didn’t get to choose where to live.
I never really “got” Jane Jacobs. I originally interpreted her as arguing that it was great for cities to be noisy and busy and full of crowds, and that we should build neighborhoods that are confusing and hard to get through to force people to interact with each other and prevent them from being able to have privacy, and no one should be allowed to live anywhere quiet or nice. As somebody who (thanks to the public school system, etc) has had my share of being forced to interact with people, and of being placed in situations where it is deliberately difficult to have any privacy or time to myself, I figured Jane Jacobs was just a jerk.
But Scott has kind of made me come around. He rehabilitates her as someone who was responding to the very real excesses of High Modernism. She was the first person who really said “Hey, maybe people like being in cute little neighborhoods”. Her complaint wasn’t really against privacy or order per se as it was against extreme High Modernist perversions of those concepts that people empirically hated. And her background makes this all too understandable – she started out as a journalist covering poor African-Americans who lived in the projects and had some of the same complaints as Brazilians.
Her critique of Le Corbusierism was mostly what you would expect, but Scott extracts some points useful for their contrast with the Modernist points earlier:
First, existing structures are evolved organisms built by people trying to satisfy their social goals. They contain far more wisdom about people’s needs and desires than anybody could formally enumerate. Any attempt at urban planning should try to build on this encoded knowledge, not detract from it.
Second, man does not live by bread alone. People don’t want the right amount of Standardized Food Product, they want social interaction, culture, art, coziness, and a host of other things nobody will ever be able to calculate. Existing structures have already been optimized for these things, and unlesss you’re really sure you understand all of them, you should be reluctant to disturb them.
Third, solutions are local. Americans want different things than Africans or Indians. One proof of this is that New York looks different from Lagos and from Delhi. Even if you are the world’s best American city planner, you should be very concerned that you have no idea what people in Africa need, and you should be very reluctant to design an African city without extensive consultation of people who understand the local environment.
Fourth, even a very smart and well-intentioned person who is on board with points 1-3 will never be able to produce a set of rules. Most of people’s knowledge is implicit, and most rule codes are quickly replaced by informal systems of things that work which are much more effective (the classic example of this is work-to-rule strikes).
Fifth, although well-educated technocrats may understand principles which give them some advantages in their domain, they are hopeless without the on-the-ground experience of the people they are trying to serve, whose years of living in their environment and dealing with it every day have given them a deep practical knowledge which is difficult to codify.
How did Jacobs herself choose where to live? As per her Wikipedia page:
[Jacobs] took an immediate liking to Manhattan’s Greenwich Village, which did not conform to the city’s grid structure.
