Camp Statement

The UMSITW concept asserts that subjective awareness is what it is like to be the proceess of updating the model of self-in-the-world [1] which has been created within the brain of each individual. The model exists and the continual updating of it occurs as a primary survival mechanism of the individual.
The model constitutes a navigational device by means of which the self - as a living body in the first instance - keeps track of where it is within its physical and social environments. The individual is able to compare outcomes of behaviour with what was planned or predicted, assess any discrepancies, and amend current movement plans or other expectations.
A key component of this theory is that subjectivity - ie an awareness of being, however rudimentary - arises from a reflexive process in which the environment is represented, the "self" is represented, and currently significant relationships between self and environment are represented. For us humans there will be a potentially reportable subjective experience, such as we loosely refer to as consciousness, whenever these three representational processes are linked and to the extent that they are linked.
This accounts for why we can have dreams at night, including lucid dreams, and why we can have hallucinations, near death experiences and so forth.
UMSITW is fairly compatibe with David Chalmers' Functional Computational Equivalence idea but requires that "functional" really mean what it says. In other words, all discussion of ineffability notwithstanding, the effective outcome is what counts so that similar inputs - physical experience - will result in the same outputs - behaviours - and the same, spontaneous, reports of personal subjectivity.
Philosophical mind games, of which the most extreme are the mathematical ontologists example the Google Groups "Everything" list contributors, and popular sci-fi, as exemplified in movies such as the "Matrix" trilogy or "The Thirteenth Floor", all tend to assume that complete emulation is possible in principle. UMSITW however holds that the essence of what is subjectively reported as consciousness is what-it-is-like-to-be the model of self in the world, or more specifically the updating of the model. That is to say the ""quality"" of the experience is "precisely" what it is like to be the of the model of the moment.
Matrix-like theories suffer from a burden of proof concerning the belief that all aspects of what is occurring within a human brain "can" be modelled within an alternative computational system. Statements to this effect are assertions of faith only and all rest on beliefs that such modelling can surmount the limitations of digital algorithms attempting to emulate analogue processes, for example:
  • the truncations of digital numbers will almost certainly cause unpredictable, non linear, excursions from the natural patterns of massively recursive signalling processes which occur in the brain, and
  • synergies and modulations within the brain arise from the proximity and overlap of physical processes such as ion channel currents across cell membranes and larger scale electrostatic and electromagnetic field changes.
favourite analogy for the interaction of all the little ion channel currents with the electromagnetic fields is the mutual interaction of small scale vibrations in domestic water valves and the large scale resonances of the piping.
A key understanding here is that *the model exists* and like all models all things it has to "be" somewhere now. The updating model within the brain is thus limited by its medium and any of it's "emulations" will be limited even more so. For those of us with a sense of humour it is worth meditating now and again on the likely dimensions of any system intended to emulate one or more human minds. I favour gravitational collapse and implosion as the greatest limiting factor. From a practical point of view it is highly unlikely there will ever be any real *emulations* of the human mind, but there almost certainly will be some very creative artificial intelligences coming into being in future. Maybe there will be millions of them or maybe just one in each self sustaining ecological/economic community. Whatever,they will not be human minds but they will surely demand, and get, the vote!
