Rex, just a few general points on your posts. The various 'existence'
arguments I've been putting forward recently are intended precisely to
show how our first-person world of meaning and intention is embedded
in a more general environment that is congruent with, rather than
alien to, these self-evident features. What of course is striking
about your proposals is that in reality nobody behaves as though they
believe this sort of thing: which is not of course to say that this
makes it uninteresting. In fact exactly the opposite: the very fact
that the world according to physics presents itself in this chilling
way makes challenging its assumptions all the more urgent.

Hence my attempts to pump intuitions about the source of the presence,
self-access and self-motivation inherent in the ontologically real, as
contrasted with the provisional and fundamentally epistemological
status of the theoretical constructions of physics. By ontologically
real I mean of course what is self-evident in the form of the
ontological first person. And in fact it really doesn't take that
much intuitive tweaking to achieve this, whether applied to the
putative primitive entities of physics, comp, or any other schema.
Essentially the intuition is that these primitives reduce in the final
analysis to the self-encounter of a primary, self-evident continuum:
i.e. a primitive self-relativisation that collapses both perception
(primitive self-access) and intention (primitive self-action) Such a
self-relativising duality of continuousness and discreteness is
indispensable to any personal account of 'owned' experience and
action, via the inheritance of such ownership from the primitive
context. From this it can naturally follow that whatever is perceived
is MY perception, whatever is done is MY action, and whatever is
determined is MY determination.

The key to seeing this is a simple appeal to the reductio ad
absurdum. Just assume the opposite (as the dogma asserts) and - pouf!
- the very appearance and sensation of anything whatsoever is
irretrievably lost. And it turns out that this assuming of the
opposite is quite unjustified by the facts. It is merely the dogmatic
adoption of the externalised 'view from nowhere' - a useful heuristic
in context - as a universal alethiometer. Of course, these basic
concepts find historic kinship with Vedantic and Buddhist insights,
and in the Western tradition via Plotinus, Kant, et al - and even in
the world-views of practising physicists such as Schroedinger and
Eddington..

I wonder if I can encourage you to take a break from contemplating the
block universe 'out there' and meditate on the intrinsic inwardness
that lies all around us?
