Hi Stephen, I agree no 3p representation can tell serve as evidence of personhood (although I do not think that means that we can't have a sense which goes beyond the 3p intuitively or instinctively, but what I'm talking about is more of the zombie question. Just because a simulation fools a high number of observers doesn't mean that it isn't a simulation, i.e. the best Elvis impersonator is not any closer to becoming Elvis Aaron Presley than they are to becoming Groucho Marx. > > To me it makes sense that the natural development of persons may be > restricted to experiences which are represented publicly in zoological > terms.

There's just no logical expectation of any kind of experiential qualities appearing in a universe which already contains fully functional unconscious systems. As far as defining life, I agree, it is a relative and qualitative concept. Like the mind body problem, in which we can say in one sense that mind and body are irreconcilable by nature and in another that they are seamlessly integrated, so too is life on the one hand indiscernible as a category of phenomena - the difference between what a virus does and what a parasite does, or the growth of a crystal vs the growth of a fungus...these are hard to draw a line, but in the life of a person, the division between life and death could not be clearer under most circumstances. In the end I think that we can neither expect life to be definable nor can it be dismissed. It, like consciousness, is actually more fundamental than definition itself. > Looking at language, the rules of spelling and grammar do not drive the > creation of new words. > > > *Looking at them* no, but *using them* can lead to the creation of > new worlds. Novelists do this constantly. > For sure, the semiotic characteristics are a major source of inspiration for neologisms, etc. It's always a push and pull, nature/nurture interaction. At every level though, it is still the user who cares about any of it and not the rules. The user uses rules, the rules have no stake in what the user does, and indeed they have no existence at all independent of all forms of user sense. > > > A word cannot be forced into common usage just because it is introduced > into a culture.

I'm talking more about the the notion that there exist phenomena which have nothing at all to do with rules, logic, or mathematics. Feelings, experience, and sense are more fundamental and can harden into rules, etc, but rules and logic, if they existed independently of feeling, could never construct any kind of feeling or experience. > > > >> >> >>> >>> What would it look like if the brain as a whole were driving the >>> neurons? >>> >>> >>> Either it would be like saying that a high level program can have a >>> feedback on some of its low level implementations, which is not a problem >>> at all, as this already exist, in both biology and computer science, or it >>> would be like saying that a brain can break the physical laws, or the >>> arithmetical laws and it would be like pseudo-philosophy. >>> >> >> What about the relation between high level arithmetic laws - like the >> ones which allow for 1p subjectivity in UM, LM, etc and the programs which >> support them? >> >> >> To eat or to be eaten relatively to the most probable universal >> neighbors.

The second way is ultimate the more desirable route to developing technology to serve the quality of public human life, but the first way is the only way to understand the physics of privacy and experience.
