In the centre of the American continent the same sort of thing happens. The bulk of the population feels that American ways are the only natural ways, American forms of government the natural forms of government, and American abuses only such as human nature makes inevitable. The same sort of thing would be found in the centre of China or of any large homogeneous continental area. It would seem, therefore, that 'insularity', so far from being a characteristic of islanders, is, on the contrary, most often to be found among the inhabitants of vast inland countries.
