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

I don't get to sleep when I'm in New York. Really. I'm living on adrenaline.

I'm not Candide, nor Dr Pangloss, but we know that faith moves mountains.

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.

We will work with everybody for the good of New York.

Winning a competition in architecture is a ticket to oblivion. It's just an idea. Ninety-nine per cent never get built.

To provide meaningful architecture is not to parody history but to articulate it.

Life it is not just a series of calculations and a sum total of statistics, it's about experience, it's about participation, it is something more complex and more interesting than what is obvious.

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.

Call Berlin. Drop everything we’re doing. I have a complete vision of what should be.
