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

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.
