Um. I'm not totally sure what relevance this has to what I posted.

Popper showed that an infinite number of theories is compatible is any
given set of finite observations.  Mere algorithmic shuffling to
calculate Pr(B) probablities according to the Bayes formula won't help
much. Successful induction needs principles to set the priors are set
correctly.

Which is largely based on aesthetic judgements.  Read the Graham
essay:
http://www.paulgraham.com/taste.html

You'll get it some day - unfortunately, I suspect, the mererely
Bayesian probablity shuffling you're using to update your beliefs may
take an inifinite time to converge to my beliefs ;)

>But what is aesthetics the study of? Of beauty? That's it isn't it?
But how can something as plastic as "beauty" have any kind of
terminal
value that you and I can both share?  Do aesthetic terminal values
decide where something fits into "aesthetic reality" or something
like
that? By the way, thanks for showing that "artistic intelligence"
may
actually represent a form of scientific understanding, a thought
dear
to my heart.

I would agree with you that aesthetics is an important driving
principle, and the top scientist _do_ recognize this (see for
instance
many quotes by Albert Einstein in this direction).
Also, you should have a look at Nietzsche - science and the aesthetic
pervade his work!

Yes, good Kim and Gunther- I’m now adopting the radical belief that
intelligence has a lot more to do with art, than math ;)

Good initial link on aesthetics:
http://en.wikipedia.org/wiki/Aesthetics

So throw away all those math books , forget about Bayes, and start
studying the arts: painting, music and so on and so forth.

We’ll finally solve the AI stuff…with art.

Yes, I was partially agreeing with you. Psychotic people often still
manage very well with deductive reasoning, but they get the big
picture wrong, obviously and ridiculously wrong. So there must be more
to discovering truth about the world than mere algorithmic shuffling.

The idea is that good mathematics is beautiful. Good music and paintings 
often have a deep mathematical structure.

No reason to throw away the math.
