Re: Is it sure that any mechanism has a largest model? (LI,8C, p.205)



Judith,

Agreed. It seems again that both our points are sustained, however. Since "system" always refers to an abstraction of a complex whole, there are no actual systems "out there" as such. They all are complexly interrelated. When the complexiologist imagins a complex system, he/she is abstracting some system, say a marsh ecosystem, and saying not only is the abstracted system complex, but we recognize that its complexity extends beyond its definition. When the complexiologist imagines a simple system, say a car or a solar system, again it is understood to be an abstraction from a complex reality, and not manifest as such. However, the issue with the old-world mechanistic view, also associated with the positivistic view in science, is that the though was popular that actual simple mechanisms could exist in nature as such, and in fact all of nature was a simple mechanism. So, what I'm pointing out is that this discussion is not really about the system itself - we all agree now that they are all more than what we describe; it is about one's concept of reality as complex or simple. If reality is complex, then there are no true simple systems that are natural systems, there are only simple systems that are formal systems - which I suggest is what we have both been saying, but I am trying to be definitive about it. I believe that saying there are indeed simple systems in nature (i.e., natural systems that are simple) is precisely the error Rosen was strongly dismissing; but indeed, if we agree that simple systems are abstractions, then we can discuss the simple aspect of the solar system which involves its dynamical, object-in-space, chemical, etc. aspects that exhibit law-like behavior, while ignoring those aspects that do not; and in that sense we can discuss a simple solar system.

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.
