Our lives are complex; our emotions are complex; our intellectual desires are complex. I believe that architecture … needs to mirror that complexity in every single space that we have, in every intimacy that we possess.

And it is very moving because one has to see the site not as just another site of development but it is a very special site. It is a site that souls and hearts of all Americans.

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.

And you have to remember that I came to America as an immigrant. You know, on a ship, through the Statue of Liberty. And I saw that skyline, not just as a representation of steel and concrete and glass, but as really the substance of the American Dream.

And, yes, I love the process of building.

Architecture is not based on concrete and steel, and the elements of the soil. It's based on wonder.

Young people have the advantage because they have their whole lives open to be astonished.
