Goethe on Europe/Germany

Goethe said in his conversation with Eckermann:

"I do not fear that Germany will not be united; our excellent streets and future railroads will do their own. Germany is united in her patriotism and opposition to external enemies. She is united, because the German Taler and Groschen have the same value throughout the entire Empire, and because my suitcase can pass through all thirty-six states without being opened. It is united, because the municipal travel documents of a resident of Weimar are accepted everywhere on a par with the passports of the citizens of her mighty foreign neighbors. With regard to the German states, there is no longer any talk of domestic and foreign lands. Further, Germany is united in the areas of weights and measures, trade and migration, and a hundred similar things which I neither can nor wish to mention."
