Hi Bruno,

So do you agree that the 3-p point of view is just an abstraction (a simulation even!) of a 1-p?

This would make the 1p fundamental. This would make vain the search for explanation of mind, so this does not satisfy me.

Dear Bruno,

In the context of a theoretical framework it does, but that is not a contradiction of my claim. We are talking about representations of 1p not the content of the 1p itself. There are situations when the map is not the territory...

With comp mind is the result of the working of a universal number relatively to infinities of other universal number, so we need to start from the numbers (or anything Turing-equivalent).

But you are assuming that numbers can do the "work". I beg to differ! Number can represent anything but can they do work? No, they do not "do" anything at all. There is no "action" in numbers. To represent action we need at least functions to map some object to some other different object.

So the 3p can be abstract, but it is not part of the mind, like "1+1=2" remains true in absence of any thinker.

But does the Truth value have any meaning in a world where it cannot be known in any way? I can only make sense of your claim here if I stipulate that you think that the truth of a statement is a proxy for the content of the statement; such that if the statement is "true" then it does not matter at all what the sentence is. I still do not grasp how you go from claim that necessitate instantiations of properties such as the particular property of the sentence "1+1=2" to the truth of the intention of the sentence. How is the sentence "#8$<%" not equally true in the absence of any thinker and have the same meaning as "1+1=2"? What is making the difference? You seem to be assuming that there is something above that some how can "see" the truth of "1+1=2" and know that it is a true sentence and that it is completely immaterial and "not a thinker". Plato was a bit more circumspect about assuming such things, I hope!

It seems to me that this would similar to having a model S that is part of a theory T such that T would change its beliefs as X -> X' changes, all while preserving the Bp&p term, p would be a variable of or in X, X', ... .

A model cannot be a part of a theory. I guess you mean a theory which is part of the theory, and then I mainly agree with your sentence.

Does not a true theory require that a model of it exist? Model-less theories? Are they even possible?

We can build theories which are part of themselves, like we can make machine which can access any part of their 3p description, by using the Dx=xx method (or Kleene second recursion theorem).

Sure, but that is a separate issue. The 3p description of a machine is, in your sentence here, taken from the intentional stance (or point of view) of another entity (that is not the machine in question), so that makes it bisimilar to the 1p of a separate entity. Where is the contradiction to my claim?
