This page was linked from Wikipedia by an impersonation sock pretending to be the original author. The sock was obviously lying. This file had not been edited by the original author, here, as history will show.
Now blanked, it had been accidentally created with an incorrect pagename in the process of importing the Parapsychology resource from Wikiversity. The updated content is at Wikiversity/Parapsychology/Sources/Steigmann/Parapsychology.
