Agnostic/gnostic and atheist/theist answer two different questions. Atheist/theist answers "What do you believe?" Agnostic/gnostic answers "What do you know?"
I am an atheist and an agnostic.
I think I know what you were trying to get at, but you can interpret "believe" and "know" in so many ways, that answer isn't sufficient.
I "believe" what I have currently concluded from the evidence. That doesn't mean I can't change that belief should new evidence emerge.
By the same token, I "believe" in the scientific principle that one cannot "prove" the negative. However, unlike agnostics, I don't apply that principle to god beliefs because I "believe" there is sufficient evidence to conclude all god beliefs are inventions of human imagination. It's really no different than people having concluded there is sufficient evidence to "believe" evolution theory is correct yet we haven't looked at every single genome, thus we cannot "prove" the negative that some organism exists that didn't evolve.
Obviously one needs to draw some conclusions (aka believe) in order to function. I understand the agnostic position which says, "no conclusion can be drawn because one cannot "prove the negative", and there is no current evidence of any real gods existing in the Universe, thus no reason to believe gods exist."
Yet you don't hear people using some term suggesting agnosticism regarding evolution theory. Why is that?
It's a type of glass half full/ glass half empty way of looking at the god question. I think the best approach is to follow the overwhelming evidence that supports the conclusion god beliefs are fabrications rather than to take what I view as the 'ignore the evidence and the obvious' position by claiming one cannot prove there are no gods because one cannot test that claim.
There are times when it is appropriate to take the agnostic position in a scientific question. When we had a narrower view of the parameters with which life could exist many scientists would say we still couldn't rule out that life exists somewhere besides on Earth because we would never be able to test every location in the Universe. But now that we have evidence the range of environments which life can survive in is much wider. So that agnosticism is giving way to a view that, given the extent of habitable zones on Earth and the number of planets in the Universe, ET life most probably exists.
My complaint about using the agnostic approach to god beliefs is that it creates a special category or double standard so to speak for god beliefs. The same is true when skeptics apply a double standard to non-evidence based beliefs claiming "faith based beliefs" are somehow excused from the application of any evidence standards. It is claimed by some that religion and science are separate, yadda yadda, I think you all know the drill there. I see no reason to apply such a double standard.
There
is evidence that god beliefs are myths. Why do we then allow this special category for some potential gods to exist when we don't think consciously of any equivalent when considering there might be some animal yet discovered that didn't evolve? The latter question never arises while the agnostic/atheist question fills pages on the forum.
I ask again, why the difference? Is it just that people don't consider following the evidence for 'god beliefs' and think they must actually look for evidence of gods? Another special category, I say. Little time is spent considering the possibility of invisible pink unicorns or fairies and leprechauns.
Time for agnostics to consider a paradigm shift, I say. Look at the evidence for god beliefs. There's plenty there to draw a conclusion about the origin of all god beliefs just as one can draw a conclusion evolution theory applies to all life. If you recognize the double standard being applied to the possibility gods might exist vs the possibility some life might exist that didn't evolve, you may recognize one can still manage the scientific principle,
there is always room for new evidence to be considered, without making a special case for the possibility of gods existing. All god beliefs are fabrications. There is evidence to that effect. No need to spend more time on some special agnostic category.
