Cities are the greatest creations of humanity.

What is a habit? It’s just a shackle for ourselves.

We often judge cities by great public buildings. But we admire great cities because people live there in a beautiful way. You have to think about how each person will live there; you can't just think about abstract ideas.

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.

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?

Cities are the greatest creations of humanity.

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.
