the humble meatling's reply
now am almost sure that atheists are hardwired like everyone else to find a belief system/mythology to explain their observations. It is not simply that they "do not need" a belief system of religious experience as the evidence is not forthcoming.
I think that this is probably true (at least for some of use -- I don't want to generalize too much) if we understand mythology in Joseph Campbell's sense of the term, in which case a mythology isn't necessarily false or true, but it refers to the way we organize our values around our beliefs to create an interpretive worldview that we use to make sense of events. My
Star Trekkish hope and belief that long-term human progress is possible in terms of science, economics, and culture, could be considered a mythology. It doesn't entail dogmatic faith claims, but it's an image of the future that I hope -- and really want to believe -- can be made true. Because I tend to evaluate the morality and decency of the acts of people and nations according to whether I think they will help to bring about such a future, all the assumptions I might use to make those evaluations -- beliefs about economics, human nature, and so on, many of which I know I can't prove -- may be considered parts of my personal mythology.
I suggest that by changing our observation point of view, by for example entering an alternative state of consciousness (other than the analytical waking consciousness common to skepticism) we can resolve this problem by experiencing the subliminal source of this need to mythologize.
This, on the other hand, doesn't make much sense to me. I'm openly conscious of my need and desire to mythologize. I'll grant that activities like seated meditation (or taking a long, quiet walk) can make a person more aware of feelings and judgments he or she tends to suppress when otherwise engaged, but I wouldn't call that an altered state of consciousness. It's really just redirecting one's attention.
Then we will not need any abstract -isms. If we then feel inclined to want to adopt an -ism we could just take a break from our skepticism enter an alternate state of consciousness then proceed again with normal life free from the need to relate to abstractions.
We will always need abstract -isms for the same reason we use abstractions in general. We use them because it's impossible and wasteful to talk about exact individual specifics all of the time. No amount of altered consciousness experiences will change this, I suspect. I also suspect that the need to mythologize and the tendency to fall back on abstractions and generalizations are closely related. It's all a side-effect of trying to get by in a complicated universe while being made of meat.
