I'm a musician. I write songs. I just hope when the day is done I've been able to tear a little corner off of the darkness.

I used to love Kurt Cobain, when he was telling people we're a pop band. People would laugh, they thought of it as good old ironic Kurt. But he wasn't being ironic.

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.

But with Christ, we have access in a one-to-one relationship, for, as in the Old Testament, it was more one of worship and awe, a vertical relationship. The New Testament, on the other hand, we look across at a Jesus who looks familiar, horizontal. The combination is what makes the Cross.

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.

U2's best work has always been when we didn't know what we're doing.

Every age has its massive moral blind spots. We might not see them, but our children will.
