Hi John (K),
You're right about any natural system that is "a mechanism" being a
fragment because complexity basically proves that "context" is inseparable from
"system" in reality. However, the word system refers to something,
which was described in Life, Itself as (this is from memory, not a direct
quote):"a collection of percepts which, to the self, seem to belong together".
That's already an abstraction based on fragmentation. So any way we speak of
systems is going to be a similar sort of fragmentation-- this goes back
to what human consciousness can "know", etc. However, insofar as we can speak of
"complex systems" in the natural world, we can also find "simple systems" or
mechanisms (which is different from "machine", by the way). My father used to
refer to a solar system as a "simple system", for example.

Judith,
It is a philosophical question indeed, however I
am inclined to say
there are no whole systems in nature that are
mechanisms. It's sort-of a
word game in a way, because if you did find a
system that you could call
a mechanisms, then I could point out that your
system definition isn't
whole, i.e., isn't complete (its a fraction). For
example, let's
consider a piece of paper as a mechanism (i.e., a "thing").
This is true
if we restrict our abstractions only to the physical
properties of what
we call the paper. But then I annoyingly come in and
point out that the
paper is part of a paper manufacturing system and was
delivered to the
classroom by a transportation system, and all involve
people and the
natural ecosystem and ultimately the entire universe. Hence
the "piece
of paper" is actually complex, unless by "piece of paper" we
agree we
are referring only to the mechanistic concept of "piece of
paper," that
concept being one in which we can define separate
state-objects in an
extended space and time.
That's basically what
I'm getting at.
