Great point Graham, and I felt that question more than thought it as I wrote that. My answer would be that for many, likely most, the question of truth or falsity either does not exist or is insufficient compared to the benefits received by believing. I've expressed this before in talking about reasons to believe. For some, the underlying facticity or truth of their belief is primary. For some, it is more about whether they see their beliefs making their lives better, richer, more fulfilling. I have disdained the second group most of my life. I do less so now. For myself, as I think you know, the search for what is true is lifelong and continues on, but so far, I have not seen sufficient reason to discard those beliefs that also give my life meaning, fulfillment, joy and comfort.
