Re: Information and Volition

There are a bunch of issues in the post by John K. so I'm going to
do that reply-insertion thing to get at them all:

The situation in modeling is different from what is happening in
the natural world because models are simple systems. My father used arrows to
encompass all the kinds of entailments that would be happening because they are
impossible to describe more concretely than that, and even that (one arrow, at
one end of a system, etc) is not accurate. There's no way to accurately model a
complex system. I would say that the arrows are describing entailment of some
sort. It may be partly information or not, it may be other kinds of entailment.
But you are correct in interpreting my father's belief that information can
entail behaviors/responses in an organism as much as any physical stimuli
can-- in fact the two are not distinguishable from each other in a model, it
seems to me-- and that the relationship between the system and these
entailments is a crucial aspect of any natural system.

Here we have an interesting problem. The term "material states" is
pure physics and is exactly why contemporary physics cannot address problems of
complexity or complex systems like those in biology. There is no such thing as a
"state" in an organism. It's a dynamical system that cannot be reduced to states
without destroying the system. It cannot be studied via that perspective because
life doesn't exist in a state-based view finder. Now, I think what John K. was
saying was something different here, but I wanted to make that point before
addressing what it is that I THINK he was saying: That if biological systems, ie
organisms, are "just as physical" and the relationships are "just as physical"
then why aren't they a universal? What my father was saying is that
contemporary physics is too limited in what it defines as
"physical". He said complexity is enlarging the view of what physics needs to be
able to "see". In other words, if you are using comtemporary physics, you
will conclude that biology IS a "special case".... but physics is only
studying the tip of the ice berg if it insists on limiting its applications by
these artificial constraints. Physics, as a field, is ignoring the
rest of the ice berg at its peril. When my father realized that atoms are
complex systems, it was a real doozy of a realization, believe
me!

I hope
I've pointed out the difference in these comparisons so that you realize that
information is something that is defined differently in an actual organism's
relationship with its environment from the relationships in a model? As far as
the definition of information becoming a universal definition in natural
systems, as in the definition being actually some sort of Natural Law... that I
don't know. It doesn't make sense to ME, personally, but I would have to look at
my father's writing on those specific aspects to sort out whether my reluctance
to accept that notion is coming from his tutelege or from my own
common sense. All I can tell you is that I perceive a difference in how
organisms behave compared to how molecules or atoms do (as well as many
other similarities and differences).
