Our Government has never given out that its object in the prosecution of the war is the extinction of slavery. It claims to have adopted emancipation only as a war measure; the great purpose of the war being avowedly the recovery of Governmental possessions and the restoration of the Union. Many moralists, failing, as we believe, to see the real significance of the idea of political unity, have looked upon the proposed object of the Government as a low and unworthy one; but have, nevertheless, rejoiced that the hand of Providence is in the work, and overruling it to bring out of these meaner aims a great and noble result. It may be well to recollect in this connection that it is not always when great moral ends are the real aim and purpose of a movement that the greatest good has been accomplished. The greatest moral results have often followed when the movement proposed no moral end whatever; while efforts having a direct moral aim have resulted in signal failure, and sometimes in disaster even to the very end proposed. Well-meant efforts to save the heathen in a spiritual way have sometimes resulted in their physical destruction, through the stealthy obtrusion of the pests of civilization. It is by no means as yet a settled question that emancipation will enhance the happiness of our negro population, or that it may not be the beginning of a series of disasters to the race which will eventuate in its extinction on this continent. The settlement of the slave question may be the beginning of the negro question; and the end of one difficulty the beginning of another. It may be that sympathy for the negro is seeking to put in train a series of changes which would terribly revulse those same sympathies, if the end could be seen from the beginning. Yet these sympathies, even if mistaken in their direct object, may be working to a great and desirable end, which they do not as yet recognize. The Crusaders aimed at what they considered a good, but, failing in that, accomplished a real good of which they had no conception. They did not make themselves permanent masters of the Holy Land, but through their intercourse with each other and with the more cultivated people of the East, they nourished the germs of a forthcoming civilization in the West.
