It's a fantastic responsibility and a wonderful moment.

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.

I think there is a new awareness in this 21st century that design is as important to where and how we live as it is for museums, concert halls and civic buildings.

We all came to see that site. We all walked around it. It is already sacred.

I studied architecture in New York. So, really I was very moved, like everyone else, to try to contribute something that has that resonance and profundity of it means to all of us.

It's a project that touched me as an immigrant and as a New Yorker.

And then, build a bustling wonderful city of the 21st century, with a restoration of a spectacular skyline, which Manhattan, of course, needs. So, that is really the design as a whole.

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

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

Well, I didn't want to have the reminder sort of in the sky, so that people would forever look at it. I wanted to have - really to create a city from the bottom up. From that foundation, which held, from the democratic power of what the site really is.

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.

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.

It's a fantastic responsibility and a wonderful moment.

Larry wanted us to reposition the tower. We wouldn't, and won't. He's been holding back our fees. We want to get paid. And that's it. It'll get solved and we'll carry on with planning Ground Zero.

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.

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

Only through acknowledgment of the erasure and void of Jewish life can the history of Berlin and Europe have a human future.

The Spiral Gallery may happen, too. It is not dependent on government funding.

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

Cities are the greatest creations of humanity.

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

When you're a kid with artistic yearnings brought up in the Bronx, you don't get fed up too easily.

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.

There will be a competition for the memorial. And then it can be developed with trees, with planting. It can become a very beautiful place protected from the streets, because it is below. And it can be something very moving and very private.

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.

The foreign press seems obsessed with the Freedom Tower, as if it was the only thing going on here. In fact, we're trying to keep a huge juggling act in balance, with the tower as just one of the many balls in play.

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

We live in a time of renaissance ... cities are coming back to life, after a long neglect.

But even with a character like Cary who is relatively outlandish, at the end of the movie he's in a place where I wouldn't have expected him to be - taking on the responsibility of a woman who is pregnant and who used to be his best friend's wife.

The productivity of work is not the responsibility of the worker but of the manager.

I couldn't be happier about being a part of 'Hunger Games' and to play Katniss. I have a huge responsibility to the fans of this incredible book and I don't take it lightly. I will give everything I have to these movies and to this role to make it worthy of Suzanne Collins' masterpiece.

I'm into the idea of responsibility and edification and these things have found me and I have found them. I wanted to be in the movie and I made it known to Mike.

We have a responsibility to ensure that every individual has the opportunity to receive a high-quality education, from prekindergarten to elementary and secondary, to special education, to technical and higher education and beyond.

The key to accepting responsibility for your life is to accept the fact that your choices, every one of them, are leading you inexorably to either success or failure, however you define those terms.

The United States cannot feed every person, lift every person out of poverty, cure every disease, or stop every conflict. But our power and status have conferred upon us a tremendous responsibility to humanity.

Until the control of the issue of currency and credit is restored to government and recognized as its most conspicuous and sacred responsibility, all talks of the sovereignty of Parliament and of democracy is idle and futile.

I think that if there are positions that you can't argue... then the responsibility is probably to resign. If one's own conscience is opposed to the requirements and responsibilities of the job, then it's time to leave the job.

The main professional responsibility of a person in business is business.

Let us all take more responsibility, not only for ourselves and our families but for our communities and our country.

For me, having a child is a really great responsibility because you've got something there that is depending on you for information and love until a certain age when it goes to school.

I appeal to my fellow scientists to remember their responsibility to humanity.

We children learned responsibility automatically.

The second is the structure and source of cults. They have always haunted me, and I wanted to explore the fundamental notion of giving up responsibility to an outside power.

I care about this state... and I feel a responsibility to get things done. If we stay healthy and play smart we can be a playoff team. I think we're on the right track.

I've no regrets. You take responsibility for your actions.

We ought to recognize that we have an offensive responsibility to take the war to the terrorists where they are. That responsibility has waned in the last year as military and intelligence resources were withdrawn from Afghanistan and Pakistan to be used in Iraq.

Somebody has to take responsibility for being a leader.

What I loathe is the multi-national conglomerates who must take responsibility for the degradation and pollution of so much of our landscape with their factory farming and greed.
