Dear Prof. Matsuno,

        I have combined your last two post to reply to them in a coherent
fashion. ;^) Please forgive the brevity of my responses. By the way, are
you familiar with the work of Howard Pattee?
(http://www.c3.lanl.gov/~rocha/pattee/)
        I am reading your paper
(http://bio.nagaokaut.ac.jp/~matsuno/preprints/krakow99.html) to
understand better your mode of thinking...

        Could we go so far as using this statement as a formal theorem? It is
interesting in that it focuses on the capacity of "making distinctions
in progress" as a fundamental property of material bodies. The notion of
Local Systems (LS) as clocking agents follows a very similar vein. :-)

        The relationship between the finiteness of an observers spatial and
temporal horizons and its ability to make distinctions is, I agree, very
important! I have been thinking of the computational "simulation"
capacities of a LS as being a measure of this finiteness toward the
goal of a "bisimulational model of LS interaction.
        We might consider this metaphorically as being a measure of how much
can be "held consistent simultaneously". I think that we could agree
that the complement of migrating inconsistencies is a moving locus of
consistency.
        The capability of moving the boundary of the collection of
mutually consistent statements or representations has a very good
pedagogical explanation in the notion of synchronizing a whole bunch of
clocks.

        The idea of selectively applying the principle of the excluded middle
(PEM) reminds me of my silly idea of constructing a set theory that is
analogous to Riemannian geometry, the latter has a variable local
geometry while the former would have a variable membership and/or
subsethood...
        The way that records "freeze" consistencies, I believe, is important to
note. But we should also note that the material in which the consistent
record of distinctions is "engraved" is by no means eternal, it to
degrades in the thermodynamic sense...
        Umm, the notion that we could halt migrating inconsistencies by
"cutting the whole into pieces" is
interesting! It looks like the situation where a geometrical manifold
where cut into small enough pieces, each piece would have zero
curvature, while the whole could have non-zero curvature. This situation
is exploited in General Relativity! The problem that I see is that the
infinitesimal pieces can not contain clocks or rulers, as Hitoshi
explains, so inconsistency is avoided by default!
        What I propose is that we consider each LS as an observer having a
large but finite space-time framing at any given "instant" of their
subjective measure of time, the migrating inconsistencies come into the
picture when we consider any acceleration as a change of the total
framing.
        In this regard I am in complete agreement with Matti's thinking! The
"geometric time" is not the subjective time, it is a record of the
precedence ordering within the frozen record. In other words, the flow
of time in the subjective experiential sense is a shifting from one
frozen Minkowskian manifold to another. This idea is still in a very
primitive state and requires discussion! :-)

        I like this thought! I tend to think of our common world as being
"generated" by an ongoing conversation ("negotiation" is a better word!)
between quantum mechanical systems. (This is part of my periodic
gossiping idea) What we can agree upon, in the consistency sense, is
what is called the "classical" world! The Universe as the totality of
Existence would be the grundlagen from which and into which the "ideas"
rise. I confess to being influenced by David Bohm's thought here! :-)

        I hope that you understand my interest in mathematical models, I
wholeheartedly agree with your thinking with regards to the difficulties
that it inherently creates. I am merely trying to generate a template or
dictionary upon with to communicate effectively with our folks. :-)
        It is interesting to note that Peter Wegner has written a paper that
deals with this very issue! See Wegner, P. Trade-offs Between Reasoning
and Modeling, in Research Directions in Concurrent Object Oriented
Programming, Eds: Agha, G.; Wegner, P.; Yonezawa, A. MIT Press (1993) pp
22-41.

        Can this be fixed? Pun intended :-)

        Bohm tended to focus on the moving point/field of explication, which we
can see as the complement of migrating inconsistencies...

        This clearly reveals the shortcomings of the conventional inductive
models that assume universal initiality. By operating within
asynchronous "windows" of consistency, we can have boundary conditions
that are subjective (in that they apply to individual LSs) and not
independent of context and history.
        I need to understand your notion of intensities better!

        Ok, but is it not an empirical model of time that we are seeking?
Perhaps I am confused... :-)

        Yes, I agree! Hitoshi's model, in showing that there can be no time
associated with the Universe as a whole, denies globally synchronous
time a priori. The best we can get is an asymptotic approximation of
such in the limit od infinite interactions among the LSs! ;^)

        I don't need much convincing of this idea, I think that it is correct.
:-)
We do, on the other hand, need to flesh out our thinking and notions so
that we can work toward implementation of the physics that is implied.
