The beam in our own eye is harder to detect, although - or more accurately because - to detect it, and remove it, is vastly more important on elementary moral grounds, and commonly more important in terms of direct human consequences as well. Intellectuals have historically played a critical function in performing these tasks, and [Ivan] Illich is right to observe that claims to scientific expertise and special knowledge are often used as a device.

The person who wins the Nobel Prize is not the person who read the most journal articles and took the most notes on them. It's the person who knew what to look for. And cultivating that capacity to seek what's significant, always willing to question whether you're on the right track - that's what education is going to be about, whether it's using computers and the Internet, or pencil and paper, or books.

Some of the most moving experiences I've had are just in black churches in the South, during the Civil Rights Movement, where people were getting beaten, killed, really struggling for the most elementary rights.

I just went along with political activists and interested in other intellectual interests which I pursued kind of at random. I never had a real college education. I got a degree, but it was just patching together courses here and there.

When I look at public opinion, I'm not far out of the mainstream. I'm in it, in many respects. In some respects, public opinion goes beyond anything I've ever said.

Looking at polls of Arab public opinion, you look at popular figures, the most popular figure is the prime minister of Turkey, Erdogan, and then it goes down the list. You get Osama Bin Laden, Saddam Hussein, you don't get Obama, or in fact any western leader. The public doesn't want the whole imperial project. So if you had democracy, it would be all over.

A tremendous amount of the entrepreneurial initiative, if you want to call it that, comes from the dynamic state sector on which most of the economy relies to socialize costs and risks and privatize eventual profit. And that's achieved by, if you like, advertising.
