Thanks Russell, for the testimony for our not being
I concur with Hal in his assumption that recent-day
physics is "close-to-right" - because it is within the
model-view of what we identified (over centuries) as
the "physical view of the world" strictly within our
actual (and continually growing) cognitive inventory
of our epistemic enrichment. Within this *model-view*
our "model-view" is (close to) right. 
That has nothing to do with the totality from which it
has been cut out.
And whatever we conclude is within our human logic and
mindset (my post to Bruno forwarded to the list).
