I have always viewed the mission of Wikipedia to be much bigger than just creating a killer website. We're doing that of course and having a lot of fun doing it but a big part of what motivates us is our larger mission to affect the world in a positive way.

Is truth always positive? Of course. Once the truth comes out you know it's all right. We're scared that if the truth comes out that it's not all right. It's the other way around.

Of course a positive growth rate might be taken as evidence that a population is below its optimum.

On the other side I do believe that the rhetoric we are seeing from the Democrats today is unprecedented is a new low in presidential politics and goes beyond political discourse and amounts to political hate speech.

I think that what I'm doing is right. And election-year politics which intensifies everything is not going to drive me off that course.

I wanted the feel in these books to be like an epic fantasy with kings queens dukes and court politics but of course like what I was explaining before about making the science make sense you have to make the politics make sense too.

Of course there are regrets. I shall regret always that I found my own authentic voice in politics. I was too conservative too conventional. Too safe too often. Too defensive. Too reactive. Later too often on the back foot.

We need to dig deep and give people a reason to be optimistic just as Obama is doing in America. Because in the same way that outcome of the U.S. elections will change the course of events there and around the world so too do politics here in Britain.

One of the big changes in politics has been because families individuals have felt worried insecure... worried about the economy worried about their jobs worried about their kids' futures... actually the disconnect between the public and media discourse and people's everyday concerns has become bigger not smaller.

Why does it have to be politics? Is there a dynamism to that world and a theoretical capacity to do things that draws many talented people? Absolutely. Are there other ways to be involved and lead an interesting life? Of course.
