We now see that the bifurcation of Anglo-Saxon national life which took place in 1776 was of all other events in modern history the one most pregnant with great consequences. The war of the Revolution led primarily to the foundation of the Republic of the United States. Its significance, however, is not exhausted by this fact, great though it is. The reflex action upon the thought and policy of Britain involved consequences as important and far-reaching. Revolution for once in our development had taken the place of Evolution, but in the end enabled the latter to resume its steady course. The revolt of the American colonies led to the closer study of the principles which must control national expansion. Britain strove, and not in vain, to acquire the art of bringing colonies into friendly relation with the national system. The nation-building energy of her people remained unimpaired, {7} and though one group of colonies had been lost, others, extending over areas far more extensive, were soon gained. Under new principles of government these were acquired, not to be lost, but retained as they have been up to the present time. Is that retention to be permanent? Is it desirable? Can the colonies be brought, and ought they to be brought, not merely into friendly relations, but into organic harmony with the national system? Has our capacity for political organization reached its utmost limit? For British people this is the question of questions. In the whole range of possible political variation in the future there is no issue of such far-reaching significance, not merely for our own people but for the world at large, as the question whether the British Empire shall remain a political unit for all national purposes, or, yielding to disintegrating forces, shall allow the stream of the national life to be parted into many separate channels.
