I am still struggling with the meaning of your concepts, but I am
trying. :) Are "thoughts" information? Do we consider them as existing
"sharply", e.g. with well defined finite properties prior to the
subjective experience of them? We must not assume that we can fix some
"external" point of view of the Totality and construct a toy model of it
and then say this "is absolutely how Nature works"! Our models and
formalisms are methods of communicating our subjective experiences, and
we try to build models that a maximum of communicators can agree upon

I will read Chamers book to try to understand the reason why he thinks
that interactive dualism does not work. It is this information that I
need to critique my thinking since I am advocating a type of interactive
dualism! From my thought so far I would answer "if contents of
consciousness are determined by 'function' of the system, that is by the
dynamical development of system, it is very difficult to see how free
will could fit into the picture" by saying that there is something
fundamentally wrong with the very concept of determinism!
We can easy see that the classical notions of determinism are plain
wrong! The idea that an isolated system's properties exist in a sharp
state independent of observation is wrong! QM forbids the construction
of a sharp Cauchy hypersurface of position and momenta with arbitrary
sharp values and thus the very idea of determinism is flawed! (thus we
have to use operators!) We are thus in a position to wrestle with some
notion that explains for both "free will" and "causality" (as opposed to
We first need to figure out exactly what we mean by "free will" and

But exactly what are "physical laws"?! Can we affirm that such are
independent of any observation? NO! I believe that "physical laws" are
the patterns of regularity that are imposed on sense data by the very
act of observation and thus do not exist as such independent of
observers! Thus I find Frieden's notions, as I have read about them so
You say that "consciousness is epiphenomena", what do you mean by that?
We really need to have a model of "free will". I find Pratt and Wegner's
notions to provide a natural way of thinking of "free will", explicitly
in the notion of "branching time". We remove the artificial notion that
all possible is available at the beginning and model process as able to
update and adapt to new information as it becomes available.
This, in my opinion, makes all the difficulties and hard problems of
consciousness and free will disappear! :) BTW, quantum nondeterminism is
just stochastisity, the absence of causality. It is a wrong notion also.

We are getting somewhere! :) Could we consider "abstractions" as traces
or spanning subsets or finite Hamiltonian paths over the set of point
\elem Totality or some other formal notion? (I don't know the right
Some work has been done outlining the limitations and strengths of
neural network computers vs. serial computers that deal with these issue
you raise. It would really benefit us to understand better computer
science. I am thus requesting for all to study his papers.

We need to carefully consider what is computation! I see these
"associations" as an example of computation! It is the identification of
*output* by a given physical process with some *input*. We think of
"input" as data or equations and variables or signals from arbitrary
sources or ... and "output" as patterns or solutions or messages or ...
The key point is that computations are constructing maps between
arbitrary classes or sets or fields or whatever. It is the
"constructing" part that is important! We must consume free energy or
equivalently generate thermodynamic entropy to create the mappings! The
associations do not "exist" a priori. They are "within" the subjective
aspect of observation.
We are dealing with aspect of Nature that are foreign to classical
ideology! We must understand that observation *is* communication, it is
a computation in the sense above, and thus involves thermodynamics and
thus we are lead into having to deal with the nature of time's arrow and
local observation actions instead of idealistic toy models that tacitly
assume knowledge when such is impossible.
