On the one hand, we have people that say the aid system is so broken we need to throw it out. And on the other we have people who say the problem is that we need more aid. ... Both sides are right. And the problem is that neither side is listening to the other. Even more problematic, they're not listening to poor people themselves.

I never got to the point where I felt that nonviolence was not viable. ... I realized that it wasn’t that it wouldn’t work, it’s that people didn’t follow the proper steps in trying to achieve it because there are a set of principles and there are a set of steps in the methodology that we were taught about nonviolence. And when we follow those they work.

Unfortunately. And it’s mostly a made-up story. It was incredible to see how it was created here. All over the news: Muslim rage or whatever. The rioting was not about being Muslim. These people have not been able to integrate. So if they have a crisis of identity, it’s forced upon them. If, after three generations of living in France, Arabs are still called Arabs and not French, then of course they will be angry. People ask why the Arabs don’t consider themselves French. Well, it’s because the French don’t consider them French. Then you had the Ministry of the Interior talking about cleaning the scum off the street. That doesn’t justify the violence—they don’t have the right to burn cities—but it explains what happened.

And I'm not here to say that men are to blame for the crisis and what happened in my country. But I can surely tell you that in my country, much like on Wall Street and the city of London and elsewhere, men were at the helm of the game of the financial sector, and that kind of lack of diversity and sameness leads to disastrous problems.

Well, yes, no, I certainly visualise … it was really … I had to have a very good idea of the geometry – that was crucial. Spacetime geometry so it's not three dimensions, you have to think of the whole four dimensional spacetime, and I get sort of used to thinking about four dimensions and using various tricks to get the picture properly. I do most of my thinking in visual terms, and I'm a very visual thinker rather than writing down equations.
