Ben:
  After all, I mean: preschoolers have fun and learn a lot mixing flour and 
butter and 
  eggs and so forth, but how realistic does the physics of such things really  
have to be to
  give a generally comparable learning experience???

  Ben,

  They have to be this realistic.

  !.Explain to me how I or any machine can recognize this (or any individual) 
human being:

  http://relationary.files.wordpress.com/2007/12/bengoertzel.jpg

  in a group of similar "hippies" or humans  [I hope you don't mind me using 
the word - but it's useful here as shorthand]. You can use any of the rational 
forms you currently use - language, maths, logic, or any kind of program. But 
I/ the machine must be able then to recognize that man.

  That challenge can be generalized as :

  2.explain to me how I or any machine can recognize any natural object  {to be 
distinguished from artificial objects, which have been human-made to represent 
rational forms - for example, a ring derived from a geometric circle).

  explain for example, how I can recognize the boulder at the front from the 
ones behind in:

  and, by extension, 

  3. how could I/or any machine distinguish and compare the properties of 
natural objects - (which is essential for doing physics -)

  a) whether one object or rock, say, has a rougher surface than another - 

  b) how a liquid flows, and how to distinguish the swirling flows of one 
liquid from another.

  c) describe to me, so I or any machine can recognize it, how a box tumbles 
when I kick it - or perform similar object "experiments"

  Comment: I think you'll find that you can't deal with, and compare, natural 
objects at all without images - and preferably not just the flat images of 
photographs and the like, but the "solid" images of direct, sensory experience. 
  Have you actually ever tried, and attempted to put your claims to any kind of 
test?
