Books! I dunno if I ever told you this, but books are the greatest gift one person can give another.

As a rock star, I have two instincts, I want to have fun, and I want to change the world. I have a chance to do both.

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.

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.

It's so sweet, I feel like my teeth are rotting when I listen to the radio.

Africa is a continent in flames. And deep down, if we really accepted that Africans were equal to us, we would all do more to put the fire out. We're standing around with watering cans, when what we really need is the fire brigade.

It's stasis that kills you off in the end, not ambition.

Ethiopia didn't just blow my mind; it opened my mind. Anyway, on our last day at this orphanage a man handed me his baby and said, 'Would you take my son with you?' He knew, in Ireland, that his son would live, and that in Ethiopia, his son would die.

Music can change the world because it can change people.

What turns me on about the digital age, what excited me personally, is that you have closed the gap between dreaming and doing. You see, it used to be that if you wanted to make a record of a song, you needed a studio and a producer. Now, you need a laptop.

The less you know, the more you believe.

The fact is that ours is the first generation that can look disease and extreme poverty in the eye, look across the ocean to Africa, and say this, and mean it. We do not have to stand for this. A whole continent written off - we do not have to stand for this.

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.

U2 is an original species... there are colours and feelings and emotional terrain that we occupy that is ours and ours alone.

To be one, to be united is a great thing. But to respect the right to be different is maybe even greater.

Books! I dunno if I ever told you this, but books are the greatest gift one person can give another.

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

So what we're talking about here is human rights. The right to live like a human. The right to live, period. And what we're facing in Africa is an unprecedented threat to human dignity and equality.

My heroes are the ones who survived doing it wrong, who made mistakes, but recovered from them.

You see, idealism detached from action is just a dream. But idealism allied with pragmatism, with rolling up your sleeves and making the world bend a bit, is very exciting. It's very real. It's very strong.

Actually oddly enough, I think my work, the activism, will be forgotten. And I hope it will. Because I hope those problems will have gone away.

Africa will thrive.

America is not just a country, it's an idea, and real Americans are getting busy.

Anyone that's involved in development has discovered that all the good work that's been done in development has been undone by the AIDS emergency.

As a musician and a songwriter, it is an act of the ego to believe that other people might be interested in your point of view. But it is usually an empathetic nature that gets you going in the first place. Music keeps the heart porous in many ways.

As hard as it is, as ghetto as it is, hip-hop is pop music. It's the sound of music getting out of the ghetto, while rock is looking for a ghetto.

At the heart of the Irish economy has always been the philosophy of tax competitiveness. On the cranky left, that is very annoying; I can see that.

Because I was suspicious of the traditional Christian church, I tended to tar them all with the same brush. That was a mistake, because there are righteous people working in a whole rainbow of belief systems - from Hasidic Jews to right-wing Bible Belters to charismatic Catholics.

Because you know when you first become famous, you start walking a little different because people are staring at you.

But more than anything else, for the British folks Irish people were all terrorists. So when we went to Britain, it was always a lot of resistance to U2. And that's why we came to America.

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.

Celebrity is ridiculous and silly and it's mad that people like me are listened to - you know, rap stars and movie stars.

Contrary to reports, this boy is not a billionaire or going to be richer than any Beatle... and not just in the sense of money, by the way; the Beatles are untouchable - those billionaire reports are a joke.

Convictions, in the end, they can be dangerous, but a world without them is just kind of an awful kind of gray, amorphous mass.

Facebook are an amazing team, a brilliant team. It's a technology that brings people together.

God is so big. It's a gigantic concept in God. The idea that God might love us and be interested in us is kind of huge and gigantic, but we turn it, because we're small-minded, into this tiny, petty, often greedy version of God, that is religion.

God's Spirit moves through us and the world at a pace that can never be constricted by any one religious paradigm.

God's Spirit moves through us and the world at a pace that can never be constricted by any one religious paradigm. I love that.

Hanging out with politicians and corporations is very unhip work. But I think that the U2 audience have turned out to be incredibly subtle in their understanding.

Happy the country that lives on nothing but its wits; cursed be the one that thinks it can get rich by planting or digging or drilling for wealth.

I accept the Old Testament as more of an action movie: blood, car chases, evacuations, a lot of special effects, seas dividing, mass murder, adultery. The children of God are running amok, wayward. Maybe that's why they're so relatable.

I always think if you are asking somebody for something it is a good idea to give them something first.

I am, as a character, at times, a little overbearing. I recognize that.

I believe that Jesus was, you know, the Son of God. And I understand that... we need to be really, really respectful to people who find that ridiculous and... preposterous.

I don't like the name, U2, actually.

I felt rich when I was 20 years old and my wife was paying my bills. Just being in a band, I've always felt blessed.

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.

I have been working for Africans since I was 18, when I got involved with the Nelson Mandela concerts. I got involved with debt cancellation because Desmond Tutu demanded that the world respond to that situation.

I have learned to interface - what I think would be the contemporary term - with various different lexicons, and people speak very different languages. I've learned to speak in a lot of tongues, and I can live with the bellicose language of some fervent, fire-breathing Christians, sure.
