You don't become an 'artist' unless you've got something missing somewhere. Blaise Pascal called it a God-shaped hole. Everyone's got one but some are blacker and wider than others. It's a feeling of being abandoned,cut adrift in space and time-sometimes following the loss of a loved one. You can never completely fill that hole-you can try with songs,family,faith and by living a full life...but when things are silent, you can still hear the hissing of what's missing.

Distance does not decide who is your brother and who is not. The church is going to have to become the conscience of the free market if it's to have any meaning in this world - and stop being its apologist.

What really turns me on about technology is not just the ability to get more songs on MP3 players. The revolution - this revolution - is much bigger than that. I hope, I believe. What turns me on about the digital age, what excites me personally, is that you have closed the gap between dreaming and doing.

The great music for so many artists - the Beatles, the Rolling Stones - was always at the moment when they were closest to pop. It would be easy for U2 to go off and have a concept album, but I want us to stay in the pop fray.

Rock 'n' roll is ridiculous. It's absurd. In the past, U2 was trying to duck that. Now we're wrapping our arms around it and giving it a great big kiss.

The idea that there is one kind of African is of course ridiculous. Sometimes African entrepreneurs want to kill you because you are saying public health is the priority, not roads. Of course they are right to press for that issue, but so are we right, I believe, to argue for example that millions of children could and should be vaccinated.

We thought that we had the answers, it was the questions we had wrong.
