Thanks for the link to @mattclarke's post - very interesting and I agree entirely :) ...... it's interesting to think just how much is the product of 'man-made' stuff. All man-made structuring, organising, writing (including religious texts, regardless of origin :) etc etc are products of thought, all divisions and groupings too. Matt's observation is astute - cities and continents, but no countries. Cities and continents retain a continuity that 'countries' do not. Pre WW1 or WW2 cities and continents no different (in location anyway :) than post, yet country lines re-drawn out of some bureaucrat's backside and onto a 'map'.

Goodness, given how some of the oldies in the UK still haven't forgiven the Germans, I don't think it would've been a good idea post WW2. Oh the insanity of it all!!
