So a lot of people have different opinions on the topic...for those of you who believe in a god or gods a deity or deities? What is true monotheism and what is true polytheism? For atheist why don't you believe in a god? What would to you qualify as one? Discuss
I think it's impossible to come up with a universally applicable definition of deity other than perhaps to say something completely circular like, "a deity is that which is called a deity." Any other definition you come up with will either exclude some things that are seen as deities or include things that aren't.
I personally tend to view the words deity or god as essentially being honorifics applied to something deemed to be awe-inspiring and of tremendous value. I generally condense that as, "a deity is something deemed to be worthy of worship."
While I think that's broad enough to include most gods without also being completely useless as a definition, it isn't without its faults. For a start, some people feel that it's
too broad and that some things should just never be thought of as gods at all. It also creates friction in cases where something is deemed worthy of worship but isn't seen as a god (such as some forms of ancestor worship). Then of course it runs into issues with various forms of misotheism and henotheism wherein something might be considered to be a god but also deemed unworthy of worship.
Hey, at least I tried!
As for pure monotheism and pure polytheism, I would say it's simply a case of how many things are deemed to be gods in their own right. If there is only one God, even if that deity has multiple forms, aspects or manifestations,* then you have monotheism. If there's more than one thing that can be thought of as a god in its own right, then you have polytheism.
*I tend to think of things like the trinity as somewhat analogous to a Portuguese man o' war. Lots of individual organisms that form a larger colonial organism. Apologies to believers in the trinity if that analogy made you wince a bit but I hope it at least makes some sort of sense.
