Don't look at the superficial success, at the short-term success. Look at the deep spiritual questions that architecture has to answer. Who do you build for? Where? What should you build?

In a strange way, architecture is really an unfinished thing, because even though the building is finished, it takes on a new life. It becomes part of a new dynamic: how people will occupy it, use it, think about it.

I believe that the idea of the totality, the finality of the master-plan, is misguided. One should advocate a gradual transformation of public space, a metamorphic process, without relying on a hypothetical time in the future when everything will be perfect. The mistake of planners and architects is to believe that fifty years from now Alexanderplatz will be perfected. -p.197

Well, I think one doesn't really have to invent this memorial space, because it is already there. And it is speaking with a voice and, you know, 4 million of us came to see the site.

It's about how to bring together the seemingly contradictory aspects of the memorial, which is about a tragedy and how it changed the world, but also about creating a vital and beautiful city of the 21st century.

And of course I like Berlin a lot. It's such an interesting city

There are more people living in Lower Manhattan now than before the terrorist attacks. That's faith for you. There's such a strong spirit here.
