Sure, "Ultimate Theory / Theory of Everything"
is really just such a thing as it is. Then,
as accessible to our reason and philosophy,
and logic and mathematics, and sense or physics,
or reason and rationale, the "theory-theoretic"
builds (or reduces) that these are the properties
of a theory of everything, which is singular,
the ultimate theory, and eventually a simple
comprehensive basis of reasoning.
It is what it is.
Set theory in its generality led into the airy
heights or "tower of rain" of trans-finite
cardinals, that it was formalized, but the
restriction of comprehension is its flaw,
because the infinite set naively is not the
ordinary infinite set, there is more to it
than that. Then, instead of that leading to
conundrum or paradox, the foundation is built
from the simple consideration of a truth-theoretic
setting, one-way as it were, with only truisms
as well formed and validities. This formalism
escaped those formalists because those were
formalists who were not platonists and didn't
have that the extra-ordinary existed regardless
their proscription of it, writing it out.
Instead this neo-classical strong platonist
(and formalist) re-approach sees the proper
axiomatization as refinement, not fiat, because
only the expansion of comprehension is truly
axiomatic (and here that it's thus just a
reflection of the structure as it is from
nothing to everything).
This quite well satisfies the formalist's
requirements, then indeed is the only
thing that does.
True theory is always right.
You can remove this part, then, though it
was really just a comment, meaning to be
inclusive.
