Re: Why is this machine not an MR Organism?



Hi Folks,
Tim is right that computers are not the best teacher about living systems
(unless you are using yours to read Robert Rosen's work, I suppose...)
However, it is worth noting that living systems would be the best teacher we
could find to develop better computers.
 I do have one concern regarding Tim's post. If we are using Aristotle's four
categories of causality to analyze the system "computer", then the Material
Cause answer to the question "Why "computer"?" (Why does this computer
exists?) would be "Because Hardware". The hardware is the matter that the
computer is made of, hence "material" cause. I suspect that electricity
would fit into this answer as well. The software, however, would constitute
"Efficient Cause" because software represents how the computer works, how it
does what it does (which are represented by metabolism and other life
processes, in an organism). The answer to the analysis in the category of
Formal Cause would be the schematics used to construct the machine and 
 
design the software. In an organism this is commonly thought to refer to
genome or DNA. The telling category, which doesn't exist from within the
computer, is Final Cause. That's because it doesn't apply to simple systems,
whereas Final Cause is the category that reveals the essence of living
systems. The final cause answer to "Why computer?" would be "Because Human
Being..." And this is precisely where the trouble is in a comparison with
the natural world. Human beings are, obviously, complex systems and science
has been wrestling with the transference of our own complexity to machines
for a long, long time. Final cause has to do with functional entailments and
when we look at computers, the functional entailments all come from human
needs.

When we use computers (or any other mechanism) to try to simulate life, we
try to paste in as many of the functional activities we can find in a living
system, but the organization of a computer is already simple (non-complex).
No amount of complicatedness will ever yield complexity because complexity
is an innate organization whereby everything about the organization is
entailed from within. You may be able to accurately "simulate" life, for a
brief time, via an extremely complicated mechanism (and this is what
cellular automata do), which is sometimes called bio-mimesis. There's a
really good chapter on this in Essays on Life, Itself (Chapter 7), which
also talks about Psycho-mimesis (artificial mind or A.I.).
