You need a prince to make a town in an intellectual sense. Developers want to make money. If they cared about architecture, they'd become architects. I've had so many projects that never came off because they had no sponsor, and not because they were utopian. I just want to build a town that's normal.
All buildings, large or small, public or private, have a public face, a facade; they therefore, without exception, have a positive or negative effect on the quality of the public realm, enriching or impoverishing it in a lasting and radical manner. The architecture of the city and public space is a matter of common concern to the same degree as laws and language—they are the foundation of civility and civilisation.
A city can only be reconstructed in the form of urban quarters. A large or a small city can only be reorganized as a large or a small number of urban quarters; as a federation of autonomous quarters. Each quarter must have its own center, periphery and limit. Each quarter must be a city within a city.
The problem was Le Corbusier was a genius and an enormous artist, but he tried to resolve problems to which there is no solution. So the idea to demolish the centre of Paris in order to adapt it to the car - he drew it! - is something not even the most bloody dictators conceived.
