Naturalism teaches one of the most important things in this world. There is only this life, so live wonderfully and meaningfully.

It's my firm conclusion that human meaning comes from humans, not from a supernatural source. After we die, our hopes for an afterlife reside in the social networks that we influenced while we were alive. If we influence people in a positive way -- even if our social web is only as big as our nuclear family -- others will want to emulate us and pass on our ideas, manners, and lifestyle to future generations. This is more than enough motivation for me to do good things in my life and teach my children to do the same.

So much of the habitat destruction and pollution is based on the simple principle that we somehow have been given free license over other species to degrade the planet.

I've written almost 200 songs with Bad Religion. No matter where you look in our history, the focus has been trying to instill some of these disturbing realities about the world, some of the implications of evolution into an artistic format that can be interpreted by people who may never study evolution.

You can't take up all the music bins at a CD retail outlet with Spice Girls CDs and leave nothing for the Joan Jett catalogue.

I want some fact-based evidence about where we came from. Things we consider mysterious need not be attributed to a deity.

Humans impart meaning and purpose to almost all aspects of life. This sense of meaning and purpose gives us a road map for how to live a good life. This guidance emerges spontaneously from the interactions of human beings living in societies and thinking together about how best to get along. It doesn't require a god or sacred text.
