A complex question, Philip. All these words people use, like deity, creator, faith, and theism pigeon holes, beliefs and religions, all these words are confusing to me and really don't seem to resonate with how I FEEL in relation to the universe - whether that is my woods, the sea, or the stars in the sky or my imagination when looking at a galaxy or trying to conceive everything at once.
Deity is a difficult concept. In the simplest form, "a power greater than I" of course I believe (I have a lot of trouble with the word 'believe') - I know! The cops, the electric company, the sun, gravity are all powers greater than I. Even my spouse is most of the time.
Do I believe that the named historical deities are individual entities who concern themselves with humanity? No. I consider these to be anthropomorphized forces or aspects of nature or idealized human archetypes (like good and evil)
Do I believe in a creator or creators? No. Except for my ancestors in personal terms. I am agnostic on how the universe came to be. I THINK it is self-creating. I also think thought is a manner of creating and may enhance the universe. No one knows how we or the universe was created. I think saying one knows is hubris and that using faith as knowing is a cop-out.
I feel I am circling around your question, "How do you conceive of deity".
Words do not suffice - but I suppose forces of Nature in relationship to me approaches how I conceive Deity.
I support the hypothesis that the Earth is one of uncountable life-bearing worlds in the universe and that if it were snuffed out in a blink it would make no difference to the universe except as the natural evolution of Nature. Nature doesnt need us, but we need Nature.
My other belief is that all is Gray. IE, neither black nor white, but everywhere in between. And I feel any belief system should be heuristic and able to change as new discoveries are made.
So, pigeonholers, what am I? Does my belief system have a name?
