No, there is no data processing in the hand. The brain is a big data
processor, of sorts. The fact that we are aware of the meaning of the
data we process, the fact that the processing is accessable to
processing, and that each concept is part of a conceptual background
is what makes us beleive we are free agents. There is no need to
postulate a prime mover, no more than it is necessary to postulate an
initiator neurone. No neurone fires whithout input, so where is the
initiator? It dosn't exist. Think of the concept of the grandmother
neurone.

And we do. It is just that I maintain the expirience of self-awareness
to be a computable process.

OK, but do you or not? Do you think the rat is thinking, in the same
way we think, about food, and the *meaning* of the red light? Or it it
a learned mechanism in the rats NN?

Why dont you ?

There is an infinate regress weather you want to *solve* it or not. I
think that the infinate regress is only what makes thinking about
thinking so confusing.

Right you are. But I find it all interesting though. Wherever you go,
there is intuition staring you in your face. There is no way to
rationally explain you intuitions.
