In 1934 the great Austrian writer Joseph Roth, in The White Cities wrote a remarkable passage about this subject:
"One might say: patriotism has killed Europe...European culture is much older than the European nation-states. Greece, Rome, Israel, Christendom and Renaissance, the French Revolution and Germany's eighteenth century, the polyglot music of Austria and the poetry of the the Slavs: these are the forces that have formed Europe...All are naturally opposed to the barbarity of so-called national pride. The imbecile love of the 'soil' kills the love of the earth. The pride of being born in a particular country, within a particular nation, wrecks the feeling of European universality."
