Hi Eray - 

I certainly agree with what you note here. The problem with arguments,
rationales, etc. is that they are only about as useful as people's
comprehension of them. I think they are conclusive once understood but
Neil considers them totally or mostly word salad and you seem to be
somewhere in the middle.

But I'll say one thing for the arguments, they're brief. So they admit
of evaluation in pretty straightforward terms. The only complicated
rationale is for S "differences between differences" resolution of
Russell's paradox and I'll be posting more on that in a few days.

The unfortunate thing is they don't have any obvious direct relevance
to immediate issues in ai as the subject stands. The only significance
I can think of at the moment is that these ideas indicate that the
idea of actual sentience in ai is really something more than programs
and whatever one chooses to project as ai in turing terms.

This latter is more on the order of robotics or in cognitive arenas
what I refer to as artificial neural turologies - ants. Which I find
nothing wrong with because it will probably prove more useful than
actual models of general cognition. However as Jim Bromer points out
in his Re: Reasoning and AI yesterday, it has been the case that
designers and programmers have thought they were more or less
discovering and writing equations of cognitive behavior and sentience
with their programs and that has definitely not proven to be the case.
So I consider that it would behoove ai architects to understand why so
they can reconsider whether they are aiming at actual cognition or
just robotics and the difference between the two.
