In an entry on my blog, I mentioned about a BBC TV program where evolutionary biologist Richard Dawkins (of "The God Delusion" fame) is now going after faith healers and other supernatural claims. It seems that he found that entry and made a comment to it. He reported that he's working on a writing project that deals with a broader examination of all supernatural "phenomena". In the comment, he asked for evidence for a "non-physical" thing that exist. So far, since he posted it, no one has taken him on his challenge. Zz.
