Hi Bruno,
I found the quote I had been searching for: http://plato.stanford.edu/entries/kant-mind/ "Kant thought that transcendental arguments were a priori or yielded the a priori in all three ways. Nonetheless, at the heart of this method is inference to the best explanation. When introspection [the empirical, not logical method of synthesis] fell out of favour about 100 years ago, the alternative approach [Kant's method of synthesis] adopted was exactly this approach. Its nonempirical roots in Kant notwithstanding, it is now the major method used by experimental cognitive scientists. Other things equally central to Kant's approach to the mind have not been taken up by cognitive science, as we will see near the end, a key part of his doctrine of synthesis and most of what he had to say about consciousness of self in particular. Far from his model having been superseded by cognitive science, some important things have not even been assimilated by it.

But we need not abandon itr entirely, as you seem to have done, and as cognitive theory has done. We can replace [1p] by its actions - those of perception, in which terms are relational (subject: object). You seem to deal with everything from the 3p perspective. That is my argument for using semiotics, which includes 1p (or interprant) as a necessary and natural part of its triad of relations. Your responses seem to leave out such relations. I cannot find again the quote I should have bookmarked, but in an argument for using semiotics on the web, it was said that modern cognitive theory has abandoned the self in an effort to depersonalize cognition. While this is a valid scientific reason, it doesn't work when living breathing humans are concerned. IMHO leaving out [1p ] in such a way will forever prevent computer calculations from emulating the mind.

Some actual machines knows already that, and can justified that If there are machine (and from outside we can know this to correct) then the 1p-truth is not codable. The 1p truth are more related to the relation between belief and reality (not necessarily physical reality, except for observation and sensation). Even the simple, and apparently formal Bp & p is NOT codable. Most truth about machine, including some that they can know, are not codable. Many things true about us is not codable either. Let me see if I understand that. I think you are saying that p, i.e. that "p" describes a fact about the world, a meta-level above the coding of a machine. No, p is for some statement at the base level, like 1+1 = 2. That the Mars Rover believes it is south of it's landing point is implicit in its state and might be inferred from its behavior, but there is no part of the state corresponding to "I *believe* I am south of my landing point." Then Mars Rover is not L?ian. But I am not even sure that Mars Rover is Turing universal, or that it exploits its Turing universality. But PA and ZF can represent "I believe". So we can study the logic of a new 'knowledge" operator defined (at the meta level, for each arithmetical proposition) by Bp & p. For example if p is "1+1=2", it is Believe"("1+1=2") & 1+1 = 2. We cannot define such operator in arithmetic. We would need something like Believe"("1+1=2") & True("1+1 = 2"), but True, in general cannot defined in arithmetic. Yet, we can metadefine it and study its logic, which obeys a soprt of temporal intuionistic logic (interpreting the S4Grz logic obtained). One could include such second-level states (which one might want to communicate to Pasadena) but then that state would be just another first-level state. Right? Not sure I see what you mean. The meta, available by the machine is in the "I believe". It is the 3-I. The presentation of myself to myself. The 1-I will be the non definable operator above. We connect the believer to the truth. It is easy to do for the sound correct machine. Bruno Brent -- You received this message because you are subscribed to the Google Groups "Everything List" group.
