Catalonia is a state of mind as well as a physical space. On our newly drawn map, it stretches roughly from the delta of the Ebro River south of Barcelona to the Mediterranean marshes and the Cevennes mountains north of Perpignan in France. It's Catalonia on both sides of the border, wherever the inhabitants think of themselves as Catalan. It is not so much a political statement, although there is some of that, but an emotional response: a matter of the heart, not the brain.
