Science is very vibrant. There are always new observations to be found. And it's all in the interest in challenging the authority that came before you. That's consistent with the punk rock ethos that suggests that you should not take what people say at face value.

The vocal arrangements are a big part of the formula for a Bad Religion song - layered harmonies and background vocals. So when I start to describe the elements of Bad Religion's sound, it starts to sound like a Christmas choir.

As I’ve said, I’ve never believed in God, which technically makes me an atheist (since the prefix “a” means “not” or “without”). But I have problems with the word “atheism.” It defines what someone is not rather than what someone is. It would be like calling me an a-instrumentalist for Bad Religion rather than the band’s singer. Defining yourself as against something says very little about what you are for.

I don't believe, for instance, that evolutionary biology or any scientific endeavor has much to say about love. I'm sure a lot can be learned about the importance of hormones and their effects on our feelings. But do the bleak implications of evolution have any impact on the love I feel for my family? Do they make me more likely to break the law of flaunt society's expectations of me? No. I simply does not follow that human relationships are meaningless just because we live in a godless universe subject to the natural laws of biology.

There are certain ways you have to delude yourself. Self-delusion is important, for instance in family life. You know what I mean? If you're in love with your wife you have to go in there with blind faith. You have to support everything. And with your kids, you have to believe that you're doing something that has higher purpose; even though you don't have any evidence that that's the way it's going to turn out.

Unfortunately, the average guy on the street believes that studying evolution leads to atheism.

I was in a choir as a kid. It was from those early days that my outlook on harmonies and arrangements were nurtured. I always took that with me, even on the earliest Bad Religion record, which strangely was only about six years after that.
