Hi Joseph,

Glad to have you join in. My goal is (paraphrasing Einstein) to
develop a model system that is as simple as possible but not too
simple to provide a foundation for formalizing the concepts of
reference and significance. If too simple, it would be helpful to know
what is specifically missing.

In considering more complex model systems the critical constraint is
to avoid cryptically assuming a homuncular perspective that sneaks in
some undescribed mentality (often an external observational
perspective) to do the interpretive work and to define what
constitutes reference and significance. I am unwilling to use a
bacterium as my model, because we implicitly assume their end-directed
and sensing capacities without explaining them. Nor am I willing to
assume that nucleic acids are intrinsically informational or that
information is just pattern replication, as has become a common
assumption in many evolutionary theories.

As I have said a number of times, my goal is not to deal with all
aspects of the information concept, and certainly not at the level of
human thought. I merely propose to dissolve the implicit dualism in
our current concepts at the most basic level, so that for example it
will be possible to develop a scientifically grounded theory of
molecular biosemiotics.

As to the point that we need to consider quantum effects, I worry that
it also allows another black box to stand in for an explanation.
Quantum effects are definitely real, and though well described, their
interpretation is even less approachable than the concepts of
reference and significance in information. I worry that we risk trying
to explain one mystery by invoking an even greater mystery. I suspect
that there are aspects of quantum theory that are problematic
precisely because we lack a clear understanding of the referential
aspect of information. So the reanalysis of information that I am
suggesting may actually contribute to a better understanding of the
information provided by quantum experiments, rather than the other way
around. The key link is to the concept of physical work (which I argue
is essential for defining reference and significance). In this
submicroscopic domain where the concept of physical work requires a
different framing (though what this is is not obvious), the very
nature of reference must also be reframed. This is an implication of
this analysis that I would love to see developed.
