Berlin is still a very edgy place, a very cosmopolitan place. It's a place where completely different ideas and cultures come together and clash in a very warm way. In a very warm-hearted way. It's a very young city. It's a vibrant city. It's an exciting city. It's a city that's also scarred by history. I think that's to be celebrated and graffiti is to be celebrated. Graffiti in Berlin is very different than when they spray something on the wall dividing the west bank and Israel. And should be treated as such in Berlin.

I think that the environment is very a complicated question. I am very sympathetic to people who support the environment who live in the United States. I am very sympathetic to people who don't support the environment who live in a very poor country.

I think it's fantastically narcissistic to believe that in the entire universe, with all of the planetary systems that we've already discovered and the countless others that are out there, that we are the only forms of life.

The United States is not longer going to be the world's policemen and our days of determining you're in or you're out around the world no matter what the level of direct American interest or connection are going to be very limited. Increasingly, Africa will be doing that.

Authoritarian governments are now trying to ensure that the increasingly free flow of ideas and information through cyberspace fuels their economies without threatening their political power.

I would rather people not smoke. I certainly appreciate the fact that smoking is not legal in restaurants and bars. That used to stop me from going out at night because you'd go someplace and your clothes would reek and you wouldn't enjoy the experience and that affects your rights. It's always a question. Whenever you are talking about these issues, it's not a question of restricting rights. It's a question of restricting whose rights, and providing for whose rights and that's a tricky balance.

We live in a fantastically wealthy country. We don't have to worry about food. We don't have to worry about clothing. We don't have to worry about our safety. It's very easy for me to be an environmentalist. It's very easy for me to care about making sure that we protect the forests and the whales, and all that stuff.
