Unfortunately, the author is heavily biased in favor of the soul/spirit explanation, as can be seen by the sudden change of tone when he starts talking about "Materialistic" scientists.
I stopped reading when I got to that term, thinking "what's a materialis... oh, right, it's a REAL scientist". Other than that, a fascinating article, I might finish reading it now.
Max Planck:
"I regard consciousness as fundamental. I regard matter as derivative from consciousness. We cannot get behind consciousness. Everything that we talk about, everything that we regard as existing, postulates consciousness." http://en.wikiquote.org/wiki/Max_Planck
Pretty sure Planck was a real scientist.
