The Grid makes the history of architecture and all previous lessons of urbanism irrelevant. It forces Manhattan's builders to develop a new system of formal values, to invent strategies for the distinction of one block from another. The Grid's two-dimensional discipline also creates undreamt-of freedom for three-dimensional anarchy. The Grid defines a new balance between control and de-control in which the city can be at the same time ordered and fluid, a metropolis of rigid chaos.

The acceptance of certain realities doesn't preclude idealism. It can lead to certain breakthroughs.

Manhattanism is the one urbanistic ideology that has fed, from its conception, on the splendors and miseries of the metropolitan condition—hyper-density—without once losing faith in it as the basis for a desirable modern culture. Manhattan's architecture is a paradigm for the exploitation of congestion.

Criticism per se does not worry me. I've always solicited it as part of the design process.

There is no plateau of resting or stabilising. Once you are interested in how things evolve, you have a kind of never-ending perspective, because it means you are interested in articulating the evolution, and therefore the potential change, the potential redefinition.

It was a book [George Packer written on our presence in Nigeria] that was killed by the response of other people. Which sounds quite cowardly, perhaps, but it was the first manifestation of what is currently a really big issue: how political correctness defines the limits of what you can do. In that sense, it was super-exciting and maybe the most magical project we did, but at the same time fraught with mixed feelings.

You need to look at inequality as a typical condition of modern society.
