RE: [agi] A 1st Step To Using Your Image-inationEd:I agree a definition of 
symbol might be helpful.  

In general there is agreement here, but some people do use the term confusingly 
in an all-purpose way.

1.Symbols : Abstract signs that have NO RESEMBLANCE to the signified.    Word - 
"tree" - no resemblance to object.  Numbers "1" "2" - no resemblance to the 
objects or number of objects described.  Logic "If p then q" -   Algebra- "x + 
y=z"   No resemblance to anything being designated.

Here's where it gets a little complex - there is no agreement about this next 
category but it's v. important

2. Graphics/ "Icons"  [like computer icons rather than Peirce's]/ Image Schemas 
 -   signs that have a real if simple and sometimes distorted OUTLINE/PATTERN 
RESEMBLANCE to their signified objects -  Computer Icons, Stick Drawings, 
Geometrical Graphs, Geometrical Figures,  Cartoons, Maps, Traffic Signs

3.Images - much more DETAILED RESEMBLANCE - pseudo- or even actual-recordings - 
photographs, movies, realistic drawings, paintings, sculptures

Computers are basically symbol processors - they can only deal in 
Graphics/Icons-as-Symbolic-Formulae  and Images-as-Symbolic-Formulae. They 
cannot deal in whole forms directly as humans do - cannot literally handle them 
and reshape them and put one on top of another to see if they fit. 

Hence the celebrated imagery debate, with Pylyshyn, in order to safeguard 
current AI,  trying to maintain that the human brain also, like current 
computers, reduces images to symbolic formulae in order to process them, 
whereas others like Kosslyn deny this.
