COMMENT:Magnum opus of the chairman of <A HREF="/bib/90">CSICOP</A>. While its theme is explicitly that of extending the skepticism used to confront paranormal claims to religion, there is much of interest here for those not interested in religious issues as well.

He contends that there is a human tendency to magical thinking, a <em>transcendental temptation</em>, that is common to paranormal and religious beliefs.
