I'm bored of saying atheism is not a belief system, but it isn't. It's not a recipe for life, it has no dogma or irrational rule based on collections of ancient hearsay. Neither does it deny a god, it's simply the decision to live your life as you see fit free of the supernatural. Atheism isn't about saying you're right, it's about saying you don't give a flying toss about all the competing supernatural belief systems claiming they're right. I actually have sympathy for paganism more so than the monotheistic religions, after all the sun and the moon really do influence our world, the sun and the soil really are the givers of life. Of course we've insulated ourselves from all of this so a rediscovery of paganism is the inevitable, understandable, angst ridden result of the supermarket, the light bulb and central heating. To say modern paganism is based upon ancient practices is no more profound than saying Gladiator is based on ancient history. Actual detail is pretty scant and interpreted from mosaics, statues and archeological detritus, we really have no clue as to form and content. Much that is written down is the roman equivalent of the daily mail or mills and boon. I mean take this Wikipedia snippet on Dianic Wicca "It was founded by Zsuzsanna Budapest in the United States in the 1970s and is notable for its focus on the worship of the Goddess (usually Artemis/Diana), and on feminism." Do you reckon the content of their ritual say more about the actual dianic rites or about Californian new age spirituality as an aspect of rapid social change.....you decide.
