In many places, the zoning prohibits the mixing of retail and residential. This stupidity has been accompanied by stupidities in municipal policy, such as disallowing accessory apartments - under the theory that renters are incapable of behaving decently.

We will have to make new arrangements, or revive bygone ones. We may, for another example, see the return of the boarding house.

For instance, the most common type of "affordable housing" in the world comes in the form of apartments over stores.

Community is not something you have, like pizza. Now is it something you can buy. It's a living organism based on a web of interdependencies- which is to say, a local economy. It expresses itself physically as connectedness, as buildings actively relating to each other, and to whatever public space exists, be it the street, or the courthouse or the village green.

The skyscraper - any building over seven stories really - will come to be seen as an experimental building type that doesn't work well in an energy-starved economy.

The aggressive incoherence of our common surroundings can be described as entropy made visible. The way we have disposed things on the landscape leads us in the direction of disorder and death. They are categorically evil. These dispositions are destroying our only home-planet and other organisms that share it. They defeat our need to care about where we are and the things in place there. They prompt us to feel that civilization is not worth carrying on. They rob us of our identity and our will to live. These things are not about personal taste or style.

If it happens that the human race doesn't make it, then the fact that we were here once will not be altered, that once upon a time we peopled this astonishing blue planet, and wondered intelligently at everything about it and the other things who lived here with us on it, and that we celebrated the beauty of it in music and art, architecture, literature, and dance, and that there were times when we approached something godlike in our abilities and aspirations. We emerged out of depthless mystery, and back into mystery we returned,and in the end the mystery is all there is.
