ZF's universe in a naive set theory would be the Russell set and
Why do people have such a hard time believing that the specification
of the set of all sets that don't contain themselves has as a sputnik
the set itself, contra the specification? Irrational numbers are
regularly modeled as convergent sequences of rationals that aren't
rational. The simple definition of division brings forth from the
integers non-integer rationals. The infinitely-straight-sided polygon
has just the one curving side.
The universe of all sets would be its own powerset, this is Cantor's
paradox. The arrow reaches its target, this is Zeno's paradox. ZF's
universe would contain itself, this is Russell's paradox.
So, then with regards to Freidman's realm of "Real Objects", here of
ZF or ZFC or ZFC with some large cardinals (that as regular would be
cardinals in ZF(C), and as irregular could be their own powersets),
then to the ultra-infinitism that there is a Universe and God sorts it
out, has that God sorts out that the Universe, mathematically, is its
And, for any being in existence, the Universe is definitely a "Real
Object", for all in it.
