Are systems real?
It is possible that many 'systems' don't
really exist at all except in our minds and by
agreement and cooperation with others. In this
sense they describe how we and others generally
behave.
System models
At best any system model gives us one
of many possible views of something of interest.
One should be skeptical about the validity of
the view contained in the particular model
chosen or developed. Reality is also
multi-layered, embedded, complex and
inter-connected. Models have the advantage of
being neat, tidy, simple, manageable... Reality
is less cooperative. The 'word is not the
thing'.
