I am non-theist. Basically I just do not care if there are any gods or not. I think they are more likely more highly evolved aliens that got involved in human gene manipulation and either left us as a failed experiment or left us to "cook" awhile before possibly returning to exploit the results.
I am perhaps a bit more anti-religious than non-religious, but it comes from bitter personal experiences and I am trying to be more tolerant of ignorance and superstition .
BUT--I do feel that there is a part of life that reflects the qualities that religion gives to "spirit". Perhaps it can be explained by science in the future. Today's sci-fi is tomorrow's sci-facts. I have had "paranormal" experiences that are difficult to explain scientifically. And I do feel there is some merit to some religious practice and paraphenalia like meditation, crystals/magnetic/harmonic vibration stuff. I know when I listen to Hindu Crystal Bowl Chakra Healing CDs I feel a physical reaction to the sound and it makes me feel better afterward. The same with some Reiki techniques. I have seen amazing synchronicities in my life and I do think that horoscopes, tarot cards, divination or even channeling have a psychological connection to the human brain that may be explained by science one day along with ESP and remote-viewing or psychokinetics.
Because of my unique (where I live it is unique!) personal philosophy I have called myself a non-theist witch. But that does not really fit me. I do not consider "magick" to be a power from some supernatural benevolent or malevolent Source. I feel the power in myself when I "do" magick. I feel it is a manipulation of natural elements through physical and psychic discipline. I love archetypes and symbols, but I am not much into the neo-paganism "everything old is new again" bit. Most of the old can't be proven, so most of the new is just someone's imagination. Which is as valid as any religion is--but not scientific or historic, and I despise intellectual dishonesty and the arrogant need for some kind of pedigree to make some belief system more valid than another one. THAT is religious hubris! I hate it.
oh yeah--my Hero is Patrick Jane of The Mentalist! (And Doctor Who.)
