Consider the real implementation of most programs though.  THey are written
in a high-level language like C, Pascal, FORTRAN, or COBOL. That's what the
programmer knew about.  The Compiler turns those symbols into symbols
that no human (usually) ever looks at or understands.  The end user sees
neither of these, he sees the user interface and understands what the 
{{program is doing from yet another perspective.  What is the intelligence
that understands the machine language symbols?

One more step higher in complexity is to consider systems with complex
memories that load memory as they go (virtual memory kinds of systems)
which have a different physical configuration each time they are executed.

One more step takes us to self-modifying languages like LISP which can 
execute and build statements in their own language.  No human ever sees 
these intermediate symbols, but those constructs are processed and
are reflected in the behavior of the program.

Finally, we have really dynamic systems like neural networks that aren't
so much "loaded with a program" as "taught" what to do.  They like us,
don't have a static program controling the behavior outputs.  In a sense
our brains become "different machines" from minute to minute as we 
learn and act.  (Some might say that large portions of the population
remain changeless through video stimulation, but this effect has not
yet been proven :-)

Are all of these working with "symbols"?  If not which are? Is it 
only humans that can identify a symbol?  What if all of the records
about punched cards were destroyed while card readers still existed,
would the little holes in card decks still be symbols? After the readers
were destroyed?
