I'll need to get my Alice out ... but to paraphrase Humpty Dumpty: ... "A 
term means exactly what I mean it to mean when I mean it to mean that."  I 
think its a false analogy to contend that scientists, lawyers, accountants 
are shamans.  The quote that comes to mind is Arthur C. Clarke's "Any 
sufficiently advanced technology will appear to be magic to the 
uninitiated."  Someone posted a reasonable quote about a Shaman living off 
of society's surplus by taking a percentage and greasing the wheels.  It's 
obvious that there is still a demand for snake oil in society ... Society 
still has Shamans:  besides the obvious God Salespeople "Place Your HANDS 
on the TV  .... You will be healed." there are the secular purveyors of 
nonsense:  Political commentators <Rush Limbaugh> and Entertainers <Howard 
Stern>, Musicians <The Spice Girls, Milli-Vanilli, Vanilla-Ice>,  Managers 
and Executives <as portrayed in Scott Adams' books>.
The difference between a Shaman and an Artisan is tough for me to pin down 
... They both create more from less, but the keys to the difference seem to 
be reproducibility and adaptability.  If a system is able to be taught and 
adapts to changing circumstances its an art.  If it can't be taught or 
requires special conditions then its a sham.
