Great social and political results have thus been attained without consciously intending them, or seeing how they were to be brought about. Our Government, without professing great moral purposes, may yet accomplish more in that direction, and this, too, by the relentless and bloody hand of war, than has ever been the result of purely moral design by the most approved moral means, on the part of any combination of mankind. It may be a crisis in history, and the ushering in of a new era. Our Government proposes to recover lost possessions, and restore the integrity of the Union. Wherefore? Ours is the most beneficent Government upon the earth, blessing the most human beings, and it should be sustained. The whole nation has contributed to the acquisition of Southern territory, and it is not meet that the Northern people should surrender their interest in the same. The Mississippi River belongs as naturally to the great West as to the South, and it should be under the control of the same sovereign power, to be used for the good of one great people. There is no natural division line between the North and South, and it would be fatal to the future peace and prosperity of this continent to attempt to make one. These are some of the reasons ordinarily given for the prosecution of this war--for our great effort to reestablish the Union. They are practical, readily comprehended, and to urge them is well--enough, really, for present practical purposes; but may there not be in the idea of political unity a meaning--a philosophical significance, if you please, which these practical and obvious considerations do not reveal? It is the confirmed conviction of the Northern people, with certain unnatural exceptions, that it is our true policy to maintain the integrity of the Union at any cost, however great; the people of the South evidently take a different view of it; the political thinkers of Europe appear to be divided in their sympathies between the North and South. An article appears in a British quarterly to prove that it is the fate of great empires to fall to pieces; and that China, Turkey, Russia, and the United States show signs of approaching dissolution. It is observed that French writers of authority in the Government have issued pamphlets to prove that the peace and stability of nations require the dismemberment of the United States. The 'fire eaters' of the South are not the only people who would like to see the United States in fragments. We have such even in the North; and in Europe, especially near the thrones, 'their name is legion.'
