It doesn't apply to the logico-mathematical system of reality, of
which the computational systems of biological organisms including
humans are a part.
Why? The answer is straightforward. Because Reality's logico-
mathematical system is entirely computational in the sense that
every state at every present moment is directly computed from the
Only in the third person perspective, but with computationalism, all
accessible realities are not computation, nor result of computation,
but they are the result of infinitely many computations mixed with the
first person indeterminacies.
Godel's Theorem does not apply to this.
Right. Gödel' theorem applies to finite or enumerable machines or
theories. Not on their models, even in arithmetic.
What Godel's Theorem says is that given some mathematical system it
is possible to formulate a correct statement
It is correct if we already know that the theory is correct, which is
doubtful for rich theories like "us", in case of comp.
which is not computable from the axioms. But Reality doesn't work
that way. It simply computes the next state of itself which is
Reality does not compute. That's the digital physics thesis, which
makes no sense. Indeed, as often explained here:
if digital physics is correct then comp is correct, BUT if comp is
correct then digital physics is incorrect. thus digital physics
entails the negation of digital physics, and this makes digital
physics incorrect (for a TOE) in all case (with comp or with non comp).
The implication is that the logico-mathematical system of reality IS
AND IN FACT MUST NECESSARILY BE logically consistent and logically
complete in every detail. If it wasn't Reality would tear itself
apart at the inconsistencies and pause at the incompletenesses and
could not exist. But Reality does exist.
OK, but we don't *know* that. We hope that. We know only that we are
conscious here-and-now. We don't *know* if there are planets and
galaxies. We bet on that. Those are theoretical assumptions.
Reality is analogous to a running software program.
Read the UDA. Apparent realities have to be much bigger than anything
we could emulate on a computer. That is already the case for
arithmetic itself. You might confuse proof and computation.
Godel's Theorem does not apply. A human could speculate as to
whether any particular state of Reality could ever arise
computationally and it might be impossible to determine that, but
again that has nothing to do with the actual operation of
Reality,since it is only a particular internal mental model of that
The universal dovetailer get all states of mind, but no states of
physical reality at all, which needs the non computable First Person
Indeterminacy on all (relative) computations. Then the bigger
"theological (true) reality" is even bigger.
