Opps. Sorry for the caps. But perhaps they were meant to be, one of my
superstitions, regarding at least my higher self.

Bruno,
If "arithmetic reality" is the 3rd-person static block-universe Platonic
being,
is then "computable reality" the dynamic first-person comp-matrix of
numerous conscious beings
and yet the "vastly greater "arithmetic reality"" may do the computations??
