 I read a book by Alistair Rae titled "Quantum Mechanics -Illusion or Reality?"
which goes into different philosophical implications quantum theory with 
Copenhagen interpretation as advocated by Neils Bohr, Werner Hiesenberg etc.

It is amusing book for an outsider like me.Everything in this book is explained
in backdrop of "Photon polarisation experiment" as a quantum event.The facts 
itself about the experiment are startling.After delving into all different 
efforts to devise self-consistent quantum philosophy, he declares that only
theory which is "Economic on presumption but expensive on Universes" was 
one which says every time a quantum event occurs, the whole universe is 
divided into two non-interacting (rather interacting in only restricted 
conditions) universes !Then he diverges into the question of "imporatnce
of observer" by investigating Mind and Matter question with emphasis on 
determining whether it is possible to have any objective reality ?All these
looked so eerie to me, that I went into Humanities library and picked up 
some books on philosophy especially Zen and other oriental and tried to 
find some meaning in their striking resemblances.Especially, Zen theory of 
"No-self" and "Theory of Void(zero)" by Buddhist monk "Nagarjuna" has really
powerful suggestions.I went back to physics books and tried to look at the 
facts about "Fundamental Particles" and I found there are none.Electrons 
and Protons continue to be divieded and things have stopped at "Quarks and
Semi-quarks" presently but nobody believes it to be final.Also, Schrodinger
's wave equation and De'Broglie's wave-particle duality has already made the 
matter pretty transperant cloud.My feeling is that as long as this subject 
is investigated with purpose (it can be anything from building some applied 
device to mollify human psyche troubled at the prospect of having to deal
with uncertainity again or reveal the TRUTH ), it will be a self-defeating 
exercise.We have to leave humano-centric thinking with Logic and Intelligence
as central paradigm.It does not mean we should believe any "Tom, Dick and Harry"
but these philosophies look worth investigating like those of Greek 
Parmenides.

 Although, My article has been on little tangent but point that I wanted 
to make was that for a physicist atleast there is no dichotomy of Material
and Spiritual worlds.
