To me, this is the most credible thing that I've read on the IC in a while. I could be misinterpreting you, but to me, it seems that you are suggesting that maybe it's more than logic and reason or some willingness to believe a fantasy that compels people to believe.
William James (a founder of modern psychology and the founder of modern pragmatics) wrote in his book 'The Varities of Religious Experiences' that there is this intuition,an internal mechanism - or a feeling, if you will, that is the principle religious experience that people who firmly believe have. He says that an intense spiritual experience requires no evidence, no logic, no reasoning. It is what it is and there is no denying it. What we may question is the explanation of that experience. When people have this experience, they more often than not attribute it to their faith and they look to their faith to recreate the experience. The faith may not make any sense to the outsider at all...but to the person who experienced this 'spiritual awakening', it makes perfect sense.
Based on William James analysis, he said that what the faith was in was of no consequence, so long as the faith existed. In fact, according to his research, the inability to have a spiritual experience or faith can lead to immense depression or worse. We actually see this in some of the most prominent philosophers who found all things spiritual to be absurd (Nietzche, father of nihilism, is a prime example). This is one of the reasons why I hesitate attacking the Bible outside of limited circles. In my opinion, unless a person is trying to advance their own personal knowledge, it is no benefit for me to poke holes in another's faith...especially considering the raw value that faith has.
