The philosopher Ludwig Wittgenstein once remarked that if you ask a man how much is two plus two and he tells you five, that is a mistake. But if you ask a man how much is two plus two and he tells you ninety-seven, that is no longer a mistake. The man you are talking to is operating with a wholly different logic from your own.

I think that the drama of people rising up demanding their own freedom is one that resonates very deeply with America. I think that President Barack Obama has tried and would like to find a way to relate to the Arab Spring, but I think he also wants to be, rightly, very careful that we don't take it over. It is very important that they own this. He is trying to influence it this way but without, "We're so never going to go to the extreme of Iraq and putting boots on the ground again."

Today, natural gas now outstrips coal as the leading provider of electricity in America. If this is as big as people believe it is, natural gas will soon be powering trucks and marine ships. Maybe even standard commercial cars that people use at home through compressed natural gas, other gas to liquids. The potential is there for more energy independence by America and a reliance on cleaner fuel - natural gas emits half as much as coal, in terms of carbon emissions. That's a real bounty.

I am hoping, though, that many of them have kids, who, when they have a moment to take a break from their iPods, Internet, or Google, will explain to their parents running the country just how the world is being flattened.

What we have in the Bush team is a faith-based administration. It launched a faith-based war in Iraq, on the basis of faith-based intelligence, with a faith-based plan for Iraqi reconstruction, supported by faith-based tax cuts to generate faith-based revenues.

If you want to get an advance machine tool job today, you need to know calculus. We know a lot of people don't, we can't expect everyone to know calculus, what do we do? We created a huge bubble that created a huge number of jobs to build houses and to be in retail. You don't have to have a lot of skills to work in the new Gap store that opened, at the latest Starbucks branch, or to hammer a nail for a new house.

If you followed this economic crisis and you do not think that the world is getting flatter, you are not paying attention. We saw the entire global economy at one time acting totally in sync. The real truth is the world is even flatter than I thought. Our mortgage crisis is killing Deutsche Bank. You still don't think the world is flat?
