Subject: Re: Evolution and Change

Robert Guralnick's suggestion that evolution means ordered change, or
at least that was part of his suggestion, leaves me a little unhappy.
As I age, I see an ordered pattern of change, but I think of it more
as degeneration than evolution.  A homeostatic process is ordered, but
not evolutionary, if by evolution we wish to imply some kind of cumula-
tive pattern.  I get the feeling that "evolution" has a teleological
(no longer a bad word in systems theory) or progressive implication,
and we are caught with a word that may or may not fit real processes.

This is why I try my best to avoid the term, prefering "emergent process,"
which arguably can be related to decreasing entropy, the movement from
a more to a less probable state.  I contrast this with "dissipation,"
which I use to refer to a process of increasing entropy.  So a constrained
dissipation offers a thermodynamic engine of the emergence of improbable
structures, which in turn constrain dissipation.  The unity and interde-
pendence of two opposite processes, which I like to call a "contradiction."
