YKY/MT>>
Mary says Clinton had sex with her.
Clinton says he wouldn't call that sex.
LOL...
But your examples are still symbolic in nature. I don't see why they
can't be reasoned via logic.
In the above example the concept "sex" may be a fuzzy concept. So
certain forms of sex may be construed as "0.75 sex" or something like
that.
YKY,
That you and others "don't see why they can't be reasoned via logic" is one
reason why my interjections are [contrary to Jim] valid even here.
Why isn't science done via logic? Why don't physicists, chemists,
biologists, psychologists and sociologists just use logic to find out about
the world? Do you see why?And bear in mind that scientists are only formal
representatives of every human being - IOW we all reason like scientists as
individuals, however crudely, if we want to find out the truth about events
in the world - & what happened with Mary & Bill, or why the car broke down.
Try suggesting that any scientist just use logic - or follow the reasoning
principles of your AGI. It would be laughable.
The reason is: all the symbols you use refer to real world objects, and the
only definitive way to find out their truth is by looking at their real
objects not just the symbols - "the evidence" - as science does.
There are then various secondhand ways - getting other people's
opinions/reports, looking at scientific data etc etc - but the only way to
assess the reliability of those is by comparing their success with respect
to other real world objects. You can't as you guys seem to - (correct me) -
quite arbitrarily -* "programmer ex machina" * - assign degrees of
confidence/certainty to information - "0.75 sex".
What is needed here - for any true General Intelligence - is a whole new
branch of metacognition to supplement logic that will set out the main
principles by which we actually reason about the world most of the time.
Logic is a v. limited form of reasoning and metacognition. It alone cannot
and never wll refer to reality. What Russell said of maths applies equally
to logic (and he was even better than you guys at both) :
Mathematics may be defined as the subject in which we never know what we are
talking about, nor whether what we are saying is true.
Bertrand Russell
The new branch of metacognition will explain how we know that Russell's
statement is, broadly, true. Logic certainly can't explain to us its own
imperfections.
