I thought I was understanding your last comments on my post, i.e:
http://www.mail-archive.com/everything-list.domain.name.hidden/
and I was preparing some comment, which can't make sense with
your present remark to Peter D Jones.
What do you mean by "real existence"?
What do you mean by a non abstract mathematical object?
It would help to know if you have studied the Universal Dovetailer
Argument, which shows that by making the comp hyp, the "physical
universe" cannot be isomorphic to a mathematical object, because "the
physical universe" can only emerge on an infinity of "overlapping
computations" as seen from some first person (plural) point of views,
and then (this is non trivial) it can be shown that this is not
captured by any mathematical objects. The reason is that the whole
collection of mathematical objects cannot be itself a mathematical
object, but physical appearances emerges from inside from a "measure"
on that undefinable whole.
With some set theories like Quine NF (New Foundations) it looks like
the whole mathematical universe could be a mathematical objects. But
then this shows that NF will got problem with comp.
The notion mathematical wholeness is very tricky (to say the least).
Actually, without comp, I have no clues how to give sense to such
wholeness.
I persist finding rather unclear the use you are making of the term
"universe", even in your monist and immaterialist (if I got you right)
sense.

PS take your time to answer. I will be busy. Also next week I will
present the Universal Dovetailer Argument in London; cf:
