Years ago, in order to stay sane, I had to really make an effort not to think about how people view us. There's just so much noise, positive and negative, and not much good comes out of thinking about it.

There's an obligation to let people know where their money is going, so the tour has an educational aspect, mostly as a way to thank people. But the most practical use is to raise money and do the research to figure out the proper ways to spend it. You want to make sure that the money doesn't just go somewhere where it does more harm than good.

I think there's some pretty amazing language in the Bible. The thing that's always been interesting to me about religion is that compared to the more modern spirituality, the West Coast pseudo-Buddhist thing that people go for these days, actual Buddhism and Islam have been looking at these philosophical questions, at really hard questions, for a long time. There's a lot of stuff that philosophy doesn't talk about, and in the secular world, a lot of times, people don't talk about these ideas, and that was always really interesting for me.

There's the idea that you have to know how to solve the world's problems in order to feel that something is morally wrong. I'm always back and forth between optimism and depression about the situation.

It would get really alienating, to have my face be the face of a cause. So much just comes down to the songs. I just want to give us the opportunity to write great songs. Even our work in Haiti is limited by how good our songs are. We just need to get rid of as much of the bullshit as possible, so we can have a life, so we have something to write about.

A lot of artists write about the same things their whole career.

I think when you've been in a band for a really long time, sometimes you don't appreciate what's good about yourself. It's easy to play something and get too focused on some small detail. It's helpful to have somebody around who can say, "No, that was good." Just so you don't get too lost or forget what you do. You need somebody you really trust who has great taste.
