        This is interesting! You are defining by metaphor the notion of "The
leftover constantly serves as an impetus for moving the subsequent
progressive mode" by using a visual picture of persons moving around in
a crowd as to avoid collisions with others that are also part of the
crowd that are doing the same. Have you considered a slightly more
mathematical treatment of this picture? The last sentence in particular
seems to me to point toward a mathematical concept ... It is one that I
am very interested in! I see Mach's Principle and true concurrency
hiding here!

        This is also very interesting to me, igniting my philosopher mode! :-)
The distinction between general and singular universals is, I also
think, important. I would like to better understand your thinking about
the relationship and differences between concrete particulars and
singular universals. I tend to think of experiences as particular
observations that could be considered in an abstract sense as
measurements, or following D. Finkelstein, experiments.
        The making of a universal statement in the present tense by any finite
entity seems to indicate automatically that the entity considers his
statement as an accurate representation of the universal and this seems
to follow the way that observers in general always have their own
standards with which to make observations. It seems to me that there
exists a tacit solipsism inherent in this notion that is not problematic
if we remember that there exists more than a single observer. The
"crowd" metaphor is applicable! The crowd is not an individual at the
same level as any person that makes it up, but crowds of persons can be
considered as individuals in comparison with each other.
        Perhaps this line of thinking will help deal with a difficulty that
Lance and I have encountered with the mathematical notions of sets and
classes!

        A question: Are conservation laws necessarily general universals in the
sense that they apply equally to all possible agents/observers in a
strict quantitative sense or merely qualitatively? For example, in the
case of the conservation laws that involve time reversal symmetry, is
this only absolute in the limit of all possible clockings?

        Peter Wegner would say that "observers perceive only the observational
equivalence classes to which objects belong and not the objects
themselves". I think that the notion of a record as it relates to it
remaining in present perfect mode needs to considered carefully. Perhaps
Barbour's ideas about "time capsules" can seed this thinking... so long
as we recognize the error of assuming that the subsets of the Universe
can have time even if the whole has none...

        It looks like the "non-frozen leftover" is analogous to the "missing
information" that is always needed to complete in the Goedelian sense
any model of the Universe. The idea of a perpetual indefiniteness
driving time "forward" is very close to my thinking that there is a deep
relationship between the "tendency of closed system to go to
equilibrium" and the asymptotic approach to Goedelian completeness by
logical systems. I see this implicit in Pratt's thinking
(http://boole.stanford.edu/chuguide.html#ratmech), but am still having
trouble articulating this idea clearly.
