AMERICA TO-DAY
"Pax Romana" was a great idea in its day, but it was imposed from without, and by military methods, upon a number of subject peoples, who did not realise and intelligently co-operate in it, but merely submitted to it. It has its modern analogue in the "Pax Britannica" of India. The idea of the United States, on the other hand, gives what may be called psychological unity to one of the largest political aggregates, both in territory and population, ever known to history. In the modern world there are only two political aggregates in any wise comparable to it: the British Empire, whereof the idea is not as yet quite clearly formulated; and the Russian Empire, whereof the idea, in so far as it belongs to the people at all, is a blind and slavish superstition. Holy Russia is a formidable idea, Greater Britain is a picturesque and pregnant idea; but the United States is a self-conscious, clearly defined and heroically vindicated idea, in whose further vindication the whole world is concerned.
