I don't bill myself as an atheist but as a naturalist. Naturalism is a belief system. A lot of scientists bristle at that. We all have to believe we can find the truth. Evidence is my guide. I rely on observation, experimentation and verification.
I want some fact-based evidence about where we came from. Things we consider mysterious need not be attributed to a deity.
Naturalism teaches one of the most important things in this world. There is only this life, so live wonderfully and meaningfully.
The thread of culture that runs through the entire history of punk is also a dedication to challenging the authoritarian.
It's been an objective of mine since I started writing songs to include both intellect and energy.
