Fuzzyquark-
I have not read the book you mention, but the idea of comparing science and metaphysics is hardly new.
I recall books like "Zen & The Art of Motorcycle Maintenance" and " The Dancing Wu Li Masters", which drew parallels between science as she was in the 1980s and philosophy as well as mystical thinking of various sorts.
Interesting and enjoyable reading, but they sometimes struggled to make more of rather vague (often semantic) similarities than was really there.
It is always tempting to assume that a vague similarity between two systems of thought implies an underlying identity between the systems, where none really exists..
What genuinely is real, is the underlying nature of the human brain which dreams up more than one view of the world, using the same wetware.
It's not possible for any human thought pattern to be both internally consistent and utterly alien, because it's derived by a brain, like yours or mine, and a shared experience, which follows certain rules. One might draw parallels between any two human activities, merely because they are human.
When we deal with data outside human experience , things do get fairly wierd. (QED/ General Relativity / String theory)
How "right" these models are, must be judged by comparison with nature. Wierdness itself is no guarantee of correctness. The essential difference between (say) QED and PSI is that , while equally bizarre, one gives predictions that experiments confirm, while the other repeatedly fails to do so.
I feel the hazard of such books is that the casual reader, while really understanding neither system deeply, may emerge with a shallow and false idea that they are saying the same thing. If the authors wrote about the similarity between marketing theory and primary education, they might make as good a case, but who would care to read it?
