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.

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.

My actions to promote peace, the mediation missions which I carried out during many conflicts, which very often occurred between brothers of the same country, are not driven by any ulterior motives or any calculations based on personal ambitions.

The brain's calculations do not require our conscious effort, only our attention and our openness to let the information through. Although the brain absorbs universes of information, little is admitted into normal consciousness.

Some years ago, I wrote a book called the Emperor's New Mind and that book was describing a point of view I had about consciousness and why it was not something that comes about from complicated calculations.

The general who wins the battle makes many calculations in his temple before the battle is fought. The general who loses makes but few calculations beforehand.

It is the mark of a great man that he puts to flight all ordinary calculations. He is at once sublime and touching, childlike and of the race of giants.

There was a project at Lawrence Livermore National Labs where many years ago they went down this path for scripting and controlling very large numerical calculations.

Nowhere are our calculations more frequently upset than in war.

It does not do to leave a live dragon out of your calculations, if you live near him.

Arab leaders worry more about making money from the profits they get from oil and gas that they turn the other way when Lebanon is being destroyed right next to them. Their neighbours are being murdered, but they only make calculations for their own benefit.

As soon, however, as capitalist competition has definitively established the equal rate of profit, that rate becomes the starting point for the calculations of the capitalists in the investment of capital in newly-created branches of production.

I don't know whether you have done your calculations but, about two or three years back, I did a first assessment of what the first successful device would be worth and it came out at about 300 trillion dollars.

It is very distressing that anyone would look at these matters from a political viewpoint. Core beliefs about when life begins and ends are far too important for any such calculations.

Because of recent improvements in the accuracy of theoretical predictions based on large scale ab initio quantum mechanical calculations, meaningful comparisons between theoretical and experimental findings have become possible.

There are many different kinds of radioactive waste and each has its own half-life so, just to be on the safe side and to simplify matters, I base my calculations on the worst one and that's plutonium.

This means I must pay close attention to the writing, but equally so to the scientific background - which sometimes means doing fairly involved calculations.

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.

We have to choose between a global market driven only by calculations of short-term profit, and one which has a human face.

You learn from a conglomeration of the incredible past - whatever experience gotten in any way whatsoever.

I've danced one time in my life. It was the most mortifying experience I ever had.

The experience of life consists of the experience which the spirit has of itself in matter and as matter, in mind and as mind, in emotion, as emotion, etc.
