One of the great dangers of dealing with language as a modality for 
communication is the concept of a definition, and the varied 
interpretations one can have of a definition.  The imprecision in a 
language lends itself to grey areas, such as

  J: Axiom == X
M: Axiom == Y

M/J: X != Y

Of course, the problem is that even with precise languages stuff like 
this happens (to wit Goedel's completeness bits).

:)

Do we really?  I expect an electron looks like every other electron (but 
never having seen one, this is of course a guess).  A foundation of our 
observational sciences include being able to discern between different 
and identical things.

I suspect that it is a little more rigorous than that.  We develop 
formalisms that allow us to test things reductio ad-absurdium to help 
define things better.  This allows us to build up rigorous and 
(hopefully) testable hypotheses.

Then again, I like the simplicity of "we do math because it is useful".
