Disunion is a violent disruption of great material interests that now are wedded together. The dream of separate State sovereignty, our great Union split into two or more confederacies, prosperous and peaceable, is Utopian. So far from the secession doctrine carried out leading to peace and prosperity, it can only lead to perpetual war and adversity. The request to be 'let alone,' is simply a request that the nation should consent to see the Constitution and Union overthrown, slavery triumphant, and the great problem that a free people can not choose its own rulers against the will of a minority prove a disgraceful failure. It is a request that a nation should purchase a temporary peace at the price of all that is dear to its liberty and self-respect. The arrogance of the demand '_to be let alone_,' is only equaled by the iniquity of the means resorted to, to break up the best Government under the sun. The question of disunion, of separate State sovereignty, was fully discussed by our fathers. Thus Hamilton, whose foresight history has proved to be prophetic, says: 'If these States should be either wholly disunited, or only united in partial Confederacies, a man must be far gone in Utopian speculations, who can seriously doubt that the subdivisions into which they might be thrown would have frequent and violent contests with each other. To presume a want of motives for such contests, as an argument against their existence, would be to forget that men are ambitious, vindictive, and rapacious. To look for a continuation of harmony between a number of independent, unconnected sovereignties, situated in the same neighborhood, would be to disregard the uniform course of human events, and to set at defiance the accumulated experience of ages.'
