It's hard to see where understanding might come from (if it exists). It's hard to see where consciousness might come from (if it exists). It's hard to see where meaning might come from (if it exists). I know why it's hard. These things don't exist. There are theories to the contrary that are embedded in the way we ordinarily talk about people and their behavior. Meaning is the most obvious case. When two sentences are paraphrases, we say they 'mean the same thing'. Then there must be a thing that they both mean, right? Thinking of that as a theory, it might be right, or it might be wrong. We ought to devise alternative theories and look for evidence. We have. I think it's wrong, myself, but opinions differ. If it does turn out to be wrong, then the effort to program meaning into a machine can never be successful -- not because meaning is essentially human, or essentially organic, or essentially analogue, or essentially denotational, or any of the other straws that have been grasped at in this discussion. But because there's simply no such thing in the world to be found in us or to be put into a machine. Greg, lee@uhccux.uhcc.hawaii.edu
