[FRIAM] Any non-biological complex systems?

Yes, it was an aside, but I think an important one to help Nick 
follow/focus with us.
>    As Russ and Nick point out, this conversation is about the boundary and its ontological status.  Russ is leaping a bit further ahead and focusing on an _effect_ of the boundary while Nick (and I) are focusing on the prerequisite for symbol machines.
I appreciate your stating it this way.  I did hear Nick ask if a system 
could (somehow?) choose it's own boundaries and dismissed it as (yet 
another) distraction but would now like to hear more.   It felt like an 
anthropomorphism to suggest a system could "choose" it's own boundaries, 
but I'm open to having that explored if anyone can/will.

Similarly, your and Stephen's sparring about boundaries (compartments in 
a refrigerator?) and the distinction of systems/subsystems, etc.    was 
not something I felt able to parse out completely, so I'm hoping your 
post here leads to more elaboration of that question.

In order to be systems, they have to have some sort of objectively determined boundary (like a petri dish).  Any bounded gob of goo can be thought of as a system.  An agent, however, must be _closed_ under some operation.  Hence, all agents are systems.  But not all systems are agents.  Whether the agent's boundary is loopy, self-defining, or not is the subject of Rosen's work (from which Kauffman's is derivative).

I'm waiting with 'bated breath, and trying to guess if this is directly 
relevant to Russ's comment/question about "living in two worlds" of 
symbol AND energy processing (if I understood his point correctly).

I wish I had more to contribute myself, perhaps I should study Rosen 
again, some more.
