I think this is one area that has been very helpful for me, being on RF. I have learned to put my thinking into far less absolute terms due to the inability to prove a given viewpoint. As a bit of an extremist, in this way, I encourage people to question my thinking, as that helps me distill my thoughts even further. Then again, I do not rely on faith to buttress my thinking.
Truth is relative to the information at hand. Change the information available and "truth" changes with it. All too often confirmation bias takes over however, excluding anything that does not fit with preconceived notions. It can take considerable effort to break through the bias of those preconceived notions.
I have a rather lot of experience to build my belief systems on, so that isn't much of a problem there. The problem with experience is danger of letting ones imagination run away with the
ramifications of said experiences. Yes, experience is essential, but one must endeavor to keep both feet on the ground, at all times. Theology, in those terms, is a work in progress and should, theoretically, always remain so and be clearly understood to be in a continual state of becoming. A theology that is engraved in stone will become little more than a tombstone.
Then again, I could be wrong.
