I am not asking about how "Somethings" evolve in your theory, I'm asking
what's your justification for claiming that the All is inconsistent.

You don't need Turing's results to show that, it is quite trivial to
construct an axiomatic system with two contradictory axioms, or with
different subsets of axioms that can be used to prove inconsistent theorems.

However, there is a distinction between saying an axiomatic system is
inconsistent, and saying there is something inconsistent in the behavior of
the Turing machine simulating that system. There will always be a single
definite truth about what symbol the Turing machine prints out at what
time--it is only when you try to interpret the *meaning* of different
strings of symbols that it prints out that you will see an inconsistency. As
an analogy, suppose I am running a complex simulation of a human being
sitting at a writing desk, and he writes two sentences on a simulated piece
of paper: "I have a beard" and "I do not have a beard". If we interpret
these sentences in terms of their english meaning, obviously they represent
inconsistent statements, but that doesn't mean the simulation itself is
somehow "inconsistent", does it? One of the statements will be true and one
will be false, so there's no problem.

Your argument would only show the All to be inconsistent if you believe that
for every axiomatic system a Turing machine can simulate, there must be a
corresponding "world" within the All where all the axioms and theorems
represent simultaneously true statements about that world. But if you
believe that, then you are saying the All must contain not only all possible
worlds, but logically impossible worlds as well. Is that what you're saying?

I don't understand what these words are supposed to mean, or how they
address my question above. Can you just answer "yes" or "no"?
