It is spiritually-rooted and entirely visceral, an emotion rather than a choice, an unquantifiable connection to place, to earth, to people and their deeds. It is like love, or religion or any other inexplicable need which springs from the soul and defines us as human.

But do you only get that in *your* place then? I get that in Yorkshire, in Andalucia and in Florence. I get it when I think of the North Bank but I dont get it anywhere else in London, I dont get it when I see a union jack or hear the anthem, quite the opposite in those cases.
