Did this make sense? I see LS's as fundamental clocks, and thus it

should be possible to consider an "ensemble of clocks" as given by a

ensemble of LSs. But, I am very sketchy in my thinking of this. :-(

Ok, this is that I suspected. I am trying to work backwards from the

notion that the ordits of LS's are orthogonal to each other. I am

wondering if it is possiple to think of LS's as subjective observers and

the orthogonality condition as making them independent of each other.

This implies to me that a space of n-dimensions can be defined by the

set of LS's, where each LS defines a dimension. Question: Would this

space have "continuous" dimensions like a Von Neumann space?

Now, as to your question about how we have a subject/object dichotomy,

re: "So I am interested in how/why the two different views could be

possible." I believe that each LS defines an observer, specifically a

"subject". This "subject" has something that it is not as an "object".

This is very important. So the "object" of the "subject" is the

"~subject". Does this make sense? It follows that ~(~subject) = subject.

I am seeing the scattering propagator (orbit?)of the LS as defining the

subjective actions of an LS and that the mapping of such to that of the

~(orbit) as defining the objective actions, e.g. the LS observes

situations that are "not" the behaviour of the scattering propagator or

orbit. The trick is to see how it is that the class or set of {~(orbit)}

is finite.

All I have right now is a metaphor, the metaphor of a dictionary. I see

the "meaning" as given by the n-ary relations that exist between

objects. In a dictionary, the meaning of each word is given by the

relationship it has with a finite number of other words. Particularly,

the relational structure that the words in the set "{definition}" have

with each other. I think that Pratt's CABAs are a formal way of thinking

of this notion.

Now, how do we think of the communication or interaction or, qua Bill's

thinking, interference, between LSs? In order for two systems to

communicate there must be at least one aspect of the systems that they

share or have in common. We can think of this as a common element in

their poset of their observations.

(BTW, Hitoshi, does the notion of a poset of observations make sense to

you? Also, do you see any big problems with Schommers work?)

I'll continue this next time...
