Clark and his interlocutors have carried on some of the discussion of religious experience, and in particular Mormon religious experience, on this page. Very nice discussion that can, of course, be applied outside of a Mormon context.
Part of what is behind some of Clark's arguments are the ambiguities in understanding a text. I don't know if he would subscribe to Nietzsche's dictum, "There are no facts, only the interpretations of facts." To which I would have said, had I been able to answer Nietzsche, "Is that a fact?"
But I would like to ask under what circumstances religious experience might fail to establish a claim. Under what circumstances might I want to say "Yeah, my feelings tell me p, but I really need to accept not-p." I'd have to scroll through a bunch of stuff to find it, but I thought Clark said that someone couldn't use religious experience to confirm a conviction that YEC is true, given the weight of the evidence against it. Of course one can, if necessary, accept all the scientific evidence for evolution and be a creationist, by accepting a version of Gosse's Omphalos. (God created the world in six days with fake evidence for evolution built in). So where are the limits on appeal to experience. I didn't think I saw anyone come in from that angle, so maybe that's a place for me to start.
