    Joe -
    As I said in an earlier posting, I am reading the paper you posted,
    and I am finding it very
    interesting. For example, I had never seen the distinction of making
    tools that are mere
    extensions of self and making tools that make tools. I find that a
    convincing and useful
    distinction that might go a long way. I wish I had known about it
    before.

    But I am so far uncomfortable with the notion of applying Godel's
    logical notions of logical
    systems to an understanding of consciousness. Pinker uses the
    analogy of a computer when he
    suggests that consciousness is just a type of monitor. Any PC has
    these monitors. It's true that
    these monitors are not entirely accurate because their very usage
    distorts the event being
    monitored, but they are nevertheless accurate enough in the
    competition for life's necessities. As
    one example, we know that one of the monitors in the upper cortex
    that monitors probability of
    events after the events have been processed somewhere in the
    lower brain distorts the actual
    probabilities quite a bit -- which is why only people with split brains
    can accurately estimate
    the probability of events. Nevertheless, given that the system
    needs a monitor, the positive
    outcome (rough estimation) evidently outweighs the negative (some
    error). PC monitors also have a
    certain amount of innaccuracy built in, but they are good enough
    the purpose they were designed
    for.

    So what I am asking is Since computers have monitors, why not
    brains? How does Godel's theory
    apply to the monitor function of a computer program? He predicts
    there would be some inaccuracies,
    but that might be quite tolerable if the advantages are sufficient.

    Joe: This goes to the problem of the necessity of postulating a
    "little guy/gal in our heads" whose job it woold be to watch such a
    monitor. Of course, such a homunculus would require a smaller
    homunculus of its own, etc., and we fall into infinite regress. This
    is why Cartesian Dualism fails.

    If this or any question is better left until after I read your entire
    article, than please
    indicate that. These are just some immediate thoughts - I'll be
    more complete later.

    Joe: I'm looking forward to it.
