Ginny from comments pointed me to this useful site, which offers an eclectic collection of paranormal writings and videos. Arthur Findlay’s On the Edge of the Etheric is one of the books available for free download. Also of interest is a video clip of the shenangigans at Camp Chesterfield, where phony “materialized spirits” were exposed by infrared photography.
Ben from comments recommends the blog Beyond Evolution by Matt Chait. I’ve read only the latest two entries (both of which are quite long), and so far I’m very impressed with the clarity and cogency of Chait’s arguments. His epic dissertation on “Evolution” is well worth a look.
