The direct phenomenal experience belongs to the non communicable or
non believable part of the gap between G and G*, or their intensional
variants. This is close to Descartes' idea that (put in a modern way)
consciousness is the fixed point of the doubt.
There is of course no closure of the physical, given that the physical
does not exist "ontologically": it is a production of the mind of the
universal numbers (relatively to addition and multiplication). In
particular consciousness is not epiphenomenal at all: its role is in
self-speeding up universal being relatively to their most probable
(normal) computational computation. This can be related to Gödel and
Blum speed-up theorem in computer science.
Your question is very vast. Hope this can help. We may come back on
this if we progress in the seventh step serie thread and beyond. I
search a way to explain this without being technical, but when I do
that, I realize Plato and Plotinus has already done that, in a way;
and today, it just look a bit shocking because it is hard to abandon
the Aristotelianist constructions.
I know that what I say is unbelievable. Indeed I show why it has to be
unbelievable. That is why I insist so much on the fact that saying yes
to the doctor ask for an act of faith, then all what I say becomes
relatively explainable from that act of faith.
