I always give the analogy of the Earth at Night picture, of 7.3 billion of us, right? And everyone says, "Well, that's population." Well, if you took the entire world's population and you lived at the density of Manhattan proper - not a bad place to live - how much space do 7.3 billion people take up? The state of Colorado. At which point I end my lectures, because I want you to be thinking ... is this really a question of population, or is this a question of land use and resource consumption? And let's face it, the top 1.3 billion of us are doing all the damage. Sorry.

In art or architecture your project is only done when you say it's done. If you want to rip it apart at the eleventh hour and start all over again, you never finish. I was one of those crazy creatures.

I loved logic, math, computer programming. I loved systems and logic approaches. And so I just figured architecture is this perfect combination.

Nothing is ever guaranteed, and all that came before doesn't predicate what you might do next.

I like to think of my work as creating a private conversation with each person, no matter how public each work is and no matter how many people are present

I deliberately did not read anything about the Vietnam War because I felt the politics of the war eclipsed what happened to the veterans. The politics were irrelevant to what this memorial was.
