A strange but interesting book, think it was recommended in a Rod Dreher blog post. Big idea - written by an historian of religion who essentially says "why do even religious studies departments, whose own data is filled with the paranormal, find it professionally impossible to consider it in a serious way?". He then goes through four authors who did consider it seriously, shares a few crazy stories, and spends most of the time talking about the conclusions they drew.
If you're wondering, near as I can tell the author is not an adherent of any traditional faith - in fact he seems even more annoyed by the "easy answers" to these phenomena offered by traditional religion, as he does the effective denials of science that the (many, many) reported strange incidents ever actually happened. He ends the book actually retelling the 20th century Fatima affair from the perspective that it sure sounds a lot like a typical UFO story, so that gives you some idea. A couple of the "conclusions" I found interesting:
1. The repeated suggestion that... something that paranormal events tend to have in common is that they contain some meaning for the person(s) involved, in fact it's almost like "we're characters in a story someone else is writing". Christian says AHEM. But especially as the authors tend to reject the idea of a transcendent God (at least as traditionally conceived), what they actually reminded me more of was sci-fi stories where we've gotten so good at creating virtual realities and artificial intelligences, that the characters we create don't realize they're just characters on a computer server somewhere. And then you get to the end of the story and you learn, of course, SO ARE WE.
2. The idea that humans are some combination of the transcendent or spiritual, and the biological. Plenty of stories here about humans who know things they have no way of knowing through their biological senses (or doing, or being, or whatever). And yet the biological nature of humans is, of course, undeniable - people suffer brain damage, get older, get diseases, their functionality is impaired in serious ways. How to reconcile those two facts? And so what you're left with (though he doesn't like this word) is the idea that the brain is some kind of filter that unites the transcendent and the physical. And then (because the author has no problem with the idea of biological evolution), you have to ask yourself how a biological organ came to be so well-suited to this task, and at that point he essentially proposes some kind of intelligent design guiding the evolution of the organ. (Again, he doesn't really believe in a "god" though, so exactly what form that would take and who is doing the designing he's pretty vague on.)
3. The idea (and I think this is why Rod recommended the book) that what we are able to perceive is somehow conditioned by language and culture. So, it is well known in Christianity that "supernatural interactions" (demon sightings, miraculous healings, etc.) seem to happen more frequently outside the United States than they do inside the United States, and nobody knows why, though various ideas are suggested. This author might say, to put it simply, we can't see such things because we have conditioned ourselves not to see them. Your thinking and even perception is not as "free" as you might think.
PS he says lots of stuff about quantum physics I found, at best, extremely speculative. You know how this goes - quantum physics says some really weird stuff, here I am observing some really weird stuff, maybe there is some connection. OK, it's slightly more concrete than that, but still extremely speculative.
