Simon - Book looks interesting BUT Arthur C Clarke is an even bigger sceptic and he produces very sound reasonings explaining many 'unexplained phenomenon'. However, even he has come across the occassional unexplainable.
However, Arthur C when he was writing much of his acclaimed studies on the paranormal was pre present day Quantum physics and it appears this bloke in the book you recommend may not be disimilar to the 'mystics' he knocks in that he is out to make money, which appears to be the sticking point when people discuss whether the paranormal is 'real' or not. This bloke is just making money by knocking it, hence just the other end of the spectrum.
I love sceptics as I was and still am a sceptic. BUT I am one who knows that somethings go beyond what is understood at present and that one day there may well be solid scientific explanations for even my own experiences.
Look at it this way, a person wants nothing to do with 'the mystical' having been brought up a dubbie and been terrified of demons their whole life.
But this person then has many peculiar and correct experiences. No longer believing in demons etc, the person begins to look for the real reason......and science begins to unfold the answers, slowly I'll admit, but it does.
