        Hello Dennis,
   Yes, in these words you do, however, you -did- go from this
point to state in order to understand one must understand
-whole- without breaking down the -whole-.
  But below, you ask questions about function by assuming one
-can't- understand the -whole- by by breaking down the parts.
  You don't forget "understanding" with questions like:
        How is clear-cutting a forest any different than
        the removal of all buildings from a city?  Is a city without
        buildings, or  any of its other sub-systems, a good example
        of a healthy, functioning city?
  But, notice, Dennis, one doesn't have to understand -how-
the electrical system (just that it does) generates power to
understand the FIS.
  Ah, you misunderstood, I said, it could be -understood-,
big difference.
  You misunderstand.  What I have said, it the evidence is
"inconclusive" and to act based upon "inconclusive" evidence
can be very -costly-.  Your point, to do nothing, can be
very costly.
  Dennis, this comes down -how- does -one- weight the various
alternatives and validity of the evidence.
  Hmm, name me -one- complex system understood -as a whole-
without breaking the sytem down into the individual systems.
        [snip]
Take care,
John
