"IT seems to me very odd that internationalists, who rebuke the narrowness of national things, seldom sympathize with really international things. Thus the man who is always hoping that a Europe without flags or frontiers will exist in the future, is quite annoyed to discover that a Europe without flags or frontiers really existed in the past. He wants to get nearer to a World State and he hates the nearest that the world ever came to a World State—the Roman Empire."
~G.K. Chesterton: The Glass Walking-Stick and Other Essays from the Illustrated London News 1905-1936.
