Do people hold the beliefs that they profess to hold? I've wondered about this for a long time as a sort of meta-epistemological thing. It is somewhat tricky to formulate this question. It is hard to give specific examples because then people would debate the merits of those positions rather than the "meta" question.
For example, religious people don't believe that atheists don't believe. They just think of that as a denial of what the atheist knows deep down. Or I have a problem believing that religious people believe. I think of it as more of a kind of pseudo-belief, or a belief of a different kind of order, like a justification for a behavior.
