I do not think so. First, consciousness is not an entity, at least, not to our knowledge.
I will argue consciousness is an entity. Let me know when you are ready to discuss this.
And secondly, I don't think it can be said that humans have mastery over nature in the way that gods are conceived to have. Humans have long been able to tame nature and shape it to our wills. But most humans are never considered to be gods. The level of control is different, and I think the word "mastery" conveys that. Humans may have some level of control but do we really have mastery?
I'm more prepared to debate this than the first point regarding consciousness.
Your original assertion: god(s):
n A supernatural entity with mastery over some aspect of nature or human interests.
And now you are elevating mastery to something more than what this assertion entails. It states "some aspect of nature or human interests." I see it as you are now saying mastering means absolute and complete control over all facets in a way that matches perfection by all observable accounts. Yeah, I realize you aren't explicitly stating this, but not sure why you are different level of control for mastery when the assertion says some aspect of nature. If I can do gardening, for instance, that would be mastery over some aspect of nature. Then it just goes back to the 'supernatural entity' portion of the assertion. I'm saying consciousness is the supernatural entity, residing in us, as us, as manifested by the universe. Though being manifested by the universe doesn't make it 'supernatural.'
But, for me, the discussion wouldn't stop at that point. I actually see it just getting started. Willing to debate this, but soundbite teaser would be that because of human consciousness, we actually draw distinctions (routinely, consistently) between "nature" and "man made" as if what is man made is not natural. And if not natural, then perhaps supernatural?
"Supernatural" is a tricky word. I like it for a couple of reasons though. Its direct translation "above nature" is pretty much precisely what I'm going for. Gods are conceived as being above nature, as its masters. Or, for the pan(en)theists and pagans, gods are basically "nature plus". Nature plus something more.
Fits in with what I'm getting at in the above assertion (teaser).
I also like it for its usual connotations of something beyond our normal understanding of nature, or something that defies (our understanding of) natural laws.
I honestly believe there will never be anything that defies our understanding of natural laws. We'll just adapt our understandings to it, and claim it as natural. Literally, if Creator God were present among us, regardless of that presentation, it would be explained by natural laws. Might take us awhile to provide full explanation on our own, or who knows perhaps Creator God would offer up perfect explanation that no scientist disputes upon peer review. Either way, I really do see it as whatever we come up with as plausibly supernatural would eventually be seen as "natural." I actually cannot think of any exceptions to this. I can conceive of things that right now if they were to occur, and are hypothetical in conception, we might currently have no way of understanding how that could occur. But if it DID, we would possibly (I would say surely) be able to explain it eventually. Here in the information age, I reckon it would take no more than a decade for some sources to offer detailed explanation on exactly what and how it occurred.
And yet, I do pause on this adaptation talk because we barely are able to stay consistent with the idea that what is man-made is natural. I think the technical minded amongst us do perfectly understand that all man-made items (without exception) are natural. But if I had a dollar for all the things claimed as unnatural because they are man-made, I'd be able to purchase all things on this planet and probably have enough leftover to buy the moon, and Venus, regardless of the asking price. (Yeah, hyperbole, but strikes me as fairly accurate.)
As you note, if gods are shown to exist, then that means they are a natural part of nature, and therefore not "supernatural". I think that's a fun argument, but not one that really effects our understanding of the meaning of "supernatural".
Agreed. I can't honestly think of any examples of something that would be a viable supernatural occurrence entity given the rigid definitions of nature / natural - well, other than whatever it is humans are up to (with their consciousness).
