Animals have maps of reality but no grammar (well at least complex grammar, with the recent advances in etology one never knows).

The grammar coming from the interaction of the brain with the surroundings/soceity/people, of course.

However I wanted to emaphazise that  this map is changed by changes in technology or in personal narratives or with a brilliant fraeaking guy (or groups of guys) coming with a brilliant history to tell (Shakespeare, Rosseau) which spread like fire. But they need a lot of time to take hold.

Keynnes and Friedman economic theories can soon become structural mappings of the world for different groups of people but they are still not. Friedman was an almost structural mythlogy in Washington and the rich elite for quite some decades (a certain subgroup of our culture like the punks, so it was a very high in the heirarchy of mappings for some people) but it was not universal and encompassing enough. So, hopefully we still have tiem to reverse it... given that in Europe it never took hold until very late and only as an alterantive narrative to the common social european consensus.

A pleasure

I therefore claim to show, not how men think in myths, but how myths operate in men's minds without their being aware of the fact. Levi-Strauss, Claude
