But this makes no sense if you only consider the natural numbers. The just
contain "123456789 + * and =". There is no notion of "veryifying" or
"ExP(x)" or even a function in the numbers.

No, they don't. You are severely confusing level and meta-level.
Even the notion of arithmetical interpretation doesn't make sense with
regards to numbers. They don't formulate anything regarding interpretations.
They just contain simply number relations.

You may invoke Gödel in that point, saying that they are more than that. But
Gödel is only proving that we can formulate higher level concepts using
numbers. He is not proving anything about numbers as a seperate axiomatic
system.
The proof only makes sense with regards to more powerful systems that use
the numbers.

If that is want science means, then science is obviously nonsense. There is
no thing "beyond" the 1p view, since everything we have is the 1p view and a
3p view is only an abstraction within it.
Yes, science can allow us to find sharable things beyond our *local
personal* viewpoint. But in your theory 1p describes all the viewpoints, not
one particular viewpoint.

Exactly, this is as meaningful as your statements, in a vacuum.
The point is simply that axioms by themselves are meaningless. We need to
make sense of them, and this itself needs something fundamentally beyond
them.

Unfortunately this just doesn't work. You never show how numbers can
actually have 1p views in the first place. The notion is completely
meaningless. It is like saying that a word has a point of view.

All you do is reflect in the numbers what is already completely beyond the
numbers. But this doesn't make sense of how 3p numbers get 1p view at all.
It just shows that you can interpret pretty much everything into numbers.

Brains are material objects, but appealing to their material constitution
begs the question?
Just to remind you, even according to COMP brains *are* material,
non-emulable objects.

Given that they are material objects, why would that not matter? I'd say it
is *bound* to matter, because it is what is fundamental about them.

There has never been a single chemical reaction in a computer. Just
simulated chemical reactions, which just don't do the same as real chemical
reactions (like transforming a certain amount of energy from on form to
another), so they don't perform the same function in the real world.

Emulation would mean functional equivalence. But we can't use a simulated
chemical reaction in the place of a real chemical reaction, thus they are
not functionally equivalent.

Your distinction between ontology and epistemology is totally abitrary.
You have never said what distninguishes the assumption that there are
numbers from the fact that we are here to observe anything (regarding
ontological status). If anything, the latter is more primitively real
because we can't get rid of it. We can forget about numbers (like in
meditation), but we can't forget that we are experiencing (there isn't even

So how does it make sense to abitrarily postulate that some aspect of
reality doesn't matter with regards to our brains?

So, at some level. I don't see how that changes anything. I just mean
digitally substituted in any way.

But why wouldn't it? It is there, why would it not matter? Why would it even
be there if it didn't matter?

I actually agree (like I have said many times). I don't identifiy brain and
mind *at all*.
The brain is "just" an object within mind, but that doesn't mean that it
somehow doesn't matter to what we experience.

If observable reality as a whole is not emulable, there can't be a level at
which there is a correct emulation, because we can't even instantiate an
abstract digital emulation into reality (because observable reality is not
digital).

How does that relate to the issue? We have no way of making statements about
the computational functionality of matter (and thus the right level) if
matter is non-digital.
It is ill-defined.

You even say yourself that the correct substitution level is unknowable. But
not only that, it can't exist, because the notion of digital substitution is
meaningless in a non-digital universe.
Sure we can have *relatively* digital substitutions (like a physical
computer). But you can't derive anything from that, because your reasoning
assumes that the substitution is digital (in a very strict sense of allowing
precise copying etc...).

But there can't, unless your assumption is taken as a vague statement,
meaning "kinda digital substitution".
In this case the brain substitution might not be digital at all, except in a
very weak sense by using anything that's - practically speaking - digital
