Imagine my surprise when, leafing through a book (pic above) on the Shroud of Turin in a Houston bookshop, I came across some pages in which they spoke of a writing of mine whose paranormal theories I no longer believed:
Some see the origin of the image on the Shroud as paranormal, rather than miraculous. They suggest that supernatural, rather than Divine, forces may be at work. Mexican parapsychologist [C.T.] has raised the possibility that the image is a ‚thoughtograph‘. There is evidence—controversial, but not easily dismissed—that some psychics can create recognizable images on film by the power of thought alone. The most famous case is that of Ted Serios, an alcoholic Chicago bellhop, whose abilities were studied intensively in the mid-1960s by the eminent researcher Jule Eisenbud. If it exists, the ability of the mind to affect the highly sensitive chemicals of photographic film would seem to be a natural variant of psychokinesis (PK)—the alteration of the state of a physical object by mental influence alone—as exhibited most famously by Uri Geller.
[C.T.]  points to a similar phenomenon, that of images appearing spontaneously on the walls and floors of buildings. He cites a welldocumented case from the 1920s, when the image of the late Dean John Liddell appeared on a wall of Oxford Cathedral. Such pictures are usually of people of special sanctity, but not always…
The rest of the quotation appears here: a blog of mine for Turin Shroud matters (I won’t post again, at The West’s Darkest Hour, shroud-related articles).
