Now the nineteenth century phrased this conception by talking about the "principle of nationality." Such interesting survivals of the nineteenth century as Mr. C.R. Buxton still talk of settling human affairs by that "principle." But unhappily for him the world is not so simply divided. There are tribal regions with no national sense. There are extensive regions of the earth's surface where the population is not homogeneous, where people of different languages or different incompatible creeds live village against village, a kind of human emulsion, incapable of any true mixture or unity. Consider, for example, Central Africa, Tyrone, Albania, Bombay, Constantinople or Transylvania. Here are regions and cities with either no nationality or with as much nationality as a patchwork quilt has colour.... Now so far as the homogeneous regions of the world go, I am quite prepared to sustain the thesis that they can only be tranquil, they can only develop their possibilities freely and be harmless to their neighbours, when they are governed by local men, by men of the local race, religion and tradition, and with a form of government that, unlike a monarchy or a plutocracy, does not crystallise commercial or national ambition. So far I go with those who would appeal to the "principle of nationality." But I would stipulate, further, that it would enormously increase the stability of the arrangement if such "nations" could be grouped together into "United States" wherever there were possibilities of inter-state rivalries and commercial friction. Where, however, one deals with a region of mixed nationality, there is need of a subtler system of adjustments. Such a system has already been worked out in the case of Switzerland, where we have the community not in countries but cantons, each with its own religion, its culture and self-government, and all at peace under a polyglot and impartial common government. It is as plain as daylight to anyone who is not blinded by patriotic or private interests that such a country as Albania, which is mono-lingual indeed, but hopelessly divided religiously, will never be tranquil, never contented, unless it is under a cantonal system, and that the only solution of the Irish difficulty along the belt between Ulster and Catholic Ireland lies in the same arrangement. Then; thirdly, there are the regions and cities possessing no nationality, such as Constantinople or Bombay, which manifestly appertain not to one nation but many; the former to all the Black Sea nations, the latter to all India. Disregarding ambitions and traditions, it is fairly obvious that such international places would be best under the joint control of, and form a basis of union between, all the peoples affected.
