I try to be careful with my own certainty about things; I like
  to know what "way of thinking" is behind my way of thinking; I
  like to challenge my own assumptions as much as i can; it's one
  of the reasons why I like to debate hot topics such as science
  and religion on occasion; by explaining what I'm thinking, I am
  forced to research and "dig deep" into understanding what I
  really believe. I don't think atheism is idiotic per se; but the
  direction I've noticed it's been taking over the last few years,
  is that it's becoming Evangelical; it's using the same
  techniques used by Evangelical Christians; except instead of
  pointing to the Bible, they point to other proofs that work as
  their Bible. Look up "New Atheism" to get an idea of the
  "thinking" behind their thinking. So yes, it is becoming a
  religion in its own right; very dependent upon a set assumptions
  that seem to "fall from the sky" (a priori is the phrase I
  think) - and challenging others based on their history and logic
  WITHOUT also challenging their OWN assumptions and looking into
  their own history. I've been looking, probably since I was 8
  years old and started questioning both the church I went to
  (Methodist) and the school I went to; and saw things that were
  wrong with it. Since that point, I've been trying to find a
  "system of thinking" that matched up with how I already saw the
  world. Very hard to do; I did a lot of religion hopping in my
  20s, Buddhist, eastern Orthodox, Unitarian, Muslim, to try to
  find truths; and I found many, but it wasn't "it" for me. In my
  30s, I studied the sciences as heavily as I could; and I found a
  lot of truths in the science too; in fact, much more than I did
  in my religious quests. But still, something was missing. Yet I
  noticed a thread tying them all together; I always had a strong
  interest in Linguistics, Metaphors, Neuobiology and the concept
  that we're our brain and our bodies and our environments -*
  rather than just "computers in a meatbag"; When I discovered
  Embodied Cognition, it "clicked" for me.* I wouldn't say that it
  is the answer for everybody, but for me, it gave me a framework
  from within which I can work from; In short, our way of thinking
  works through a series of analogies built up upon other
  analogies; "pure reason" is a nice idea; but doesn't reflect the
  neural circuitry; - our emotional system always engages first
  before we begin reasoning; making "reasoning without emotion"
  physically not possible. We may not recognize the emotions as
  emotions; but they are; certainty is an emotion, complete with
  measuable levels of chemicals, parts of the brain being
  activated during certainty. Also, I've been finding great
  benefit in going through the history behind different ways of
  thinking; I don't think any idea "fell from the sky" and is
  automatically true simply because it "makes sense"; there's a
  history behind the concepts; and travelling backwards through
  time to find the sources really is eye opening to me..
