All important architecture of the last century was strongly influenced by political systems. Look at the Soviet system, with its constructivism and Stalinism, Weimer with its Modern style, Mussolini and, of course, the Nazis and Albert Speer's colossal structures. Today's architecture is subservient to the market and its terms. The market has supplanted ideology. Architecture has turned into a spectacle. It has to package itself and no longer has significance as anything but a landmark.

That has been another interesting discovery: that basically a city [Lagos] could recover from a really deep, deep, deep pit.

The real thing we tried to look at is what happens to a society when the state is absent. At that point, the state had really withdrawn from Lagos; the city was left to its own devices, both in terms of money and services. That, by definition, created an unbelievable proliferation of independent agency: each citizen needed to take, in any day, maybe 400 or 500 independent decisions on how to survive that extremely complex system.

Infrastructure is much more important than architecture.

Nigeria was a blank on the map - there weren't even any maps. The US State Department, everyone said don't go there. It was courageous of Harvard University: the notion was that we would match Harvard students with Nigerian students, so that every student would have a guide, creating a guarantee of intimacy with the city.

Nigeria [in 1990] was all rumour, an unbelievable amount of rumour - largely about crime and almost mythical manifestations of evil.

The good is not a category that interests me.
