No it is too.

Why do you assume so? What makes a map into a territory, and why would a map want to be one?

You don't need to make a map into a territory. It is sufficient to embed the map in the territory. There will be a self-referential point, which indicates its own localization. The same occur in computer science, but is more technical to explain. It is what I have studied and applied in the cognitive science.

No need to generate them.

Then how do you explain all geometric appearances in the universe?

Two things: first there is already a lot of geometry in the extensional possible relations among the numbers (that is usual math). Then the *appearance* of geometrical and physical is explained by computer science, with the qualia aspect explained by the logic of self-reference.

It is explained in sane2004, and that is the object of many posts here.

I don't think so. I think that anything anyone has said here can give a single insight into why abstract computations could, would, or should ever clothe themselves in sensory experience of any kind, including geometry.

I hear but you don't provide any argument, other than statement of primitiveness for the experience, which is what the (Bp & p) part of the machine already say. But the machine can look inward and understand that indeed, that true primitiveness feeling is a not a proof of the primitiveness.

It exists even if you don't understand them. It is like the taxes.

The taxes are only a belief system until that belief system inspires people to direct the actions of their bodies toward enforcing it. The primeness of numbers is an analysis of counting, it need not have been discovered for the universe to be complete. Taxes need not have been invented for the universe to be complete. All that is needed for the universe is sensory perception and motor participation.

Terms like "universe", "sensory", "motor" and "participation" must be explained in a non circular way.

A body cannot be an epiphenomenon. That's does not make any sense. But
comp makes it into an epinoumenon, like ether, phlogiston, and other

Ok, but how does that change Comp's failure to explain the specific aesthetic nature of that superstition?

Why should comp fails here, and also, a failure of a theory to explain something does not mean that the theory is false. It means that some job must be done.

Ether, phlogiston, and other superstitions are superstitions because they are subject to our imagination to give them any kind of definition . Shapes, colors, textures of superstitions are not agreed upon - with matter of course, universal agreement on the macrocosmic level is their defining quality.

There is no unanimity there, and unanimity is not an evidence of truth nor even plausibility.

> The question remains though, if all bodies can be simulated,

With comp bodies cannot be emulated by Turing machine. They can be
simulated at some substitution level on which yopu might bet. careful,
it is a very important nuance to grasp if you want to understand why
machine believes in some correct local way to matter and physical laws.

I don't think that its a nuance, it's obvious. I have designed video games on a computer before, so I have no problem understanding how an avatar detects collisions and behaves as if certain colored pixels are an immobile obstruction. But that's a cartoon. It is an automated picture which reminds us of our own experience of a body. The pixels on the screen are not detecting each other, nor are the numbers in the program, it is all incidental. The collisions are figurative and anesthetic, not literal and aesthetic. Switches are being opened and closed in memory which illuminates a monitor - that's all that is going on as far as anything is concerned except in the minds of programmers and audiences. It's a one dimensional representation, it has no wholeness.

It's confusing to say that Comp can't emulate bodies...so what makes bodies then and how can Comp claim to explain consciousness without explaining our consciousness of bodies?

By a relative measure on all computations + notion of first and third person view, handled eventually through self-reference logic. See the paper mentioned.

> then why have bodies at all?

To talk and manifest our consciousness relatively to other persons.

But why does that require a body? According to Comp, numbers are the only things that really ever are 'manifested', so what could it possibly mean for numbers to manifest as bodies or persons?

A number can manifest itself relatively to a universal number which read it as a program or machine, automatically with a notion of body. Then the math explains much more, and many problems are open, of course. But that's make the research fun and worthwhile.

> If anything can be simulated as a number relation, then what's with
> all of the shapes and textures?

This is what is explained by computer science. Machines cannot avoid
them. It follows from addition and multiplication, like the prime

I don't believe you. I do not think that the shape of a literal triangle is explained by number relations unless you already have a universe which has infinite aesthetic wonders on tap to add to any meaningless recursive iteration of computers science.

You might be right, but you fail to provide an argument.
