The second mode to deal with unsafe cities is to take refuge in vehicles. This is the technique practiced in the big wild-animal reservations of Africa, where tourists are warned to leave their cars under no circumstances until they reach a lodge. It is also the technique practiced in Los Angeles.

Cities never flourish alone. They have to be trading with other cities. My new hypothesis shows why. But also in trading with each other they can't be in too different stages of development, and they can't copy one another.

That the sight of people attracts still other people, is something that city planners and city architectural designers seem to find incomprehensible. They operate on the premise that city people seek the sight of emptiness, obvious order and quiet. Nothing could be less true. The presences of great numbers of people gathered together in cities should not only be frankly accepted as a physical fact... they should also be enjoyed as an asset and their presence celebrated.

There is a quality even meaner than outright ugliness or disorder, and this meaner quality is the dishonest mask of pretended order, achieved by ignoring or suppressing the real order that is struggling to exist and to be served.

There are two ways you encounter things in the world that are different. One is everything that comes in reinforces what you already believe and everything that you know. The other thing is that you stay flexible enough or curious enough and maybe unsure of yourself enough, or may be you are more sure of yourself - I don't know which it is - that the new things that come in keep reforming your world view.

People must take a modicum of public responsibility for each other even if they have no ties to each other.

Lots of things are not possible for municipalities, suburbs, or collections of them now. They are not possible and they would become possible, because they would have more authority. They would have the same authority as a province now.
