I get to hear the really good or the really bad things in the press, but I don't read it. I can afford to say that because public opinion does not drive U2's audience.

You see, Africa makes a fool of our idea of justice. It makes a farce of our idea of equality. It mocks our pieties. It doubts our concern. It questions our commitment. Because there is no way we can look at what's happening in Africa, and if we're honest, conclude that it would ever be allowed to happen anywhere else.

The most powerful idea that's entered the world in the last few thousand years - the idea of grace - is the reason I would like to be a Christian.

Even though I'm a believer, I still find it really hard to be around other believers. They make me nervous, they make me twitch. I sorta watch my back.

Where you live in the world should not determine whether you live in the world.

Sub-Saharan Africa is also home to 400 million of the world's poorest people.

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.
