Who can say that we have yet seen the end of this process of national development? Centuries have been required for all great changes affecting the destiny of man: the centuries of the great Future may yet develop a unity among the nations themselves--a distinct political organism for the regulation of national interests, which are constantly becoming more interrelated and complex. As cities, states, and baronies were developed from individuals and tribes, and as kingdoms were developed from cities, states, and baronies, so may a mightier political fabric than has yet been known be developed from the family of nations! The law, we repeat, is, that with the advance of social dependence and complexity, the principle of unitization becomes practically more intimate and comprehensive. _It is to this law that nations owe that vitality_ of which diplomatists and constitutional lawyers take cognizance. By virtue of this law, a nation is a living organism, resisting with all its vital force whatever may threaten it with dissolution. Hence the utter folly of cherishing the idea of a 'peaceable separation' of confederated states. There can be no such thing in the order of nature. The rupture and division of a nation is a reaction against the spirit of social progress, a backward movement against the current of civilization, a terrible outrage to the organizing forces of the political realm, and can only be effected through violence and bloodshed. The more mature civilization becomes, the more difficult to effect disunion, the more terrible the penalty, and the more enduring, discordant, and wretched the consequences. The law of unitization is a universal one, being an accompaniment of all unfolding, and man worse than wastes his energy in fighting against it. It is a great law of Universal Progress; and in lifting our hands against it, we are presuming to measure arms with a Power which will be sure to overwhelm us with confusion and defeat. We must consent to go with the grand movements of the Universe, and to march to the step of Destiny, or be crushed under the resistless tread of advancing peoples! The course of industrial, mechanical, and commercial progress from savage to civilized life, goes to illustrate and confirm the view which we have taken of the course of political development.
