Do you as an atheist (and do you call yourself an atheist -personally-)
I think of myself as an 'agnostic'.
because you don't believe in any thing and any one supernatural or -just- that you do not believe in any deities period?
My atheism, such as it is, is the belief that none of the deities of the religions (Yahweh, Allah, Krishna, Vishnu and all the rest) actually name anything with any objective existence in its own right. I perceive them more like characters in fiction, human creations.
That being said, I also think of the reality around me as the greatest of mysteries at its core. I don't have a clue what the 'secret of the universe' is. I don't know how the universe originated, how it got the order that it seemingly displays, what its ultimate ground of being is, or any of that. I don't know why existence exists, why there is something rather than nothing.
I feel surrounded by mysteries at every moment. That's what's motivated my lifelong interest in philosophy.
I was wondering because I'm sure many atheists do believe in supernatural things
Perhaps I can define' nature' for the purposes of this post as the space-time-matter realm that is knowable to the conventional senses (or their instrumental extensions) through causal interactions. In that case, 'supernatural' would refer to any kind of hypothetical entities that aren't knowable in that empirical way, entities that don't interact causally with us in such a way as to be knowable by our senses (or by instruments) and may not be part of the space-time-matter realm with which science concerns itself.
I'm fascinated by the problem cases that inhabit the fuzzy edges of the scientific worldview and upon which that worldview depends. There are numbers for instance, and mathematical structures. There are principles of logical inference. There are ideas, concepts and meanings. None of these are on the face of it physical entities. It isn't entirely clear what kind of being they have or even how we know about them.
I'm not an adherent of
metaphysical naturalism, the belief that nothing can possibly exist but the natural elements, principles, and relations of the kind found in the natural sciences (most notably physics). Even if it was true, I don't know of any way that anyone could actually know it.
On the other hand, I tend towards
methodological naturalism, since anything that's unknowable to a being like me doesn't really play any role in my thinking, since by definition I have no way of knowing about those things. It's just that I can't justifiably dismiss the possibility that things are happening that beings like me know nothing about.
Put another way, I have no way of being certain that today's scientific worldview is coextensive with reality itself.
