        That's something evolution explains.


    Evolution can be used to retrospectively judge that it would be convenient 
if there
    were such things as representations, but it offers no such thing as a

    ontology of it. Evolution can also 'explain' why we have teleportation, time
    travel, and telepathy in the same way.

    If you want a causal explanation then I recommend you study computer 
science and
    learn how a computer can have representations of cities and faces.


I have taught computer classes professionally actually. I'm certified MCSE and CCEA and have been using computers on a daily basis since 1981. Computers have no representations. It is us who use pixels to represent images or transistors to represent bits of information,

...and images (in computers) represent objects.

not a computer. A computer wouldn't know the difference between a city and a face if it scanned every image of a face and a city in existence.

Then how does one manage to negotiate the surface of Mars and another to drive through the streets of Los Angeles.

I recommend you study semiotics and learn how symbols and subjects relate.

When it comes to semiotics, I'm a pragmatist. The meaning of a symbol is how it effects the perceiver. I think it's amusing that what is taken as serious academic philosophy in France is done in the U.S. as marketing research.
