Seward's address on the "Irrepressible Conflict," which closes this volume, is representative of the division between the two sections, as it stood just before the actual shock of conflict. Labor systems are delicate things; and that which the South had adopted, of enslaving the laboring class, was one whose influence could not help being universal and aggressive. Every form of energy and prosperity which tended to advance a citizen into the class of representative rulers tended also to make him a slave owner, and to shackle his official policy and purposes with considerations inseparable from his heavy personal interests. Men might divide on other questions at the South; but on this question of slavery the action of the individual had to follow the decisions of a majority which, by the influence of ambitious aspirants for the lead, was continually becoming more aggressive. In constitutional countries, defections to the minority are a steady check upon an aggressive majority; but the southern majority was a steam engine without a safety valve.
In this sense Seward and Lincoln, in 1858, were correct; the labor system of the South was not only a menace to the whole country, but one which could neither decrease nor stand still. It was intolerable by the laws of its being; and it could be got rid of only by allowing a peaceable secession, or by abolishing it through war. The material prosperity which has followed the adoption of the latter alternative, apart from the moral aspects of the case, is enough to show that the South has gained more than all that slavery lost.
ON THE MISSOURI BILL--UNITED STATES SENATE,
The Constitution declares "that Congress shall have power to dispose of, and make all needful rules and regulations respecting the territory and other property of the United States." Under this power Congress have passed laws for the survey and sale of the public lands; for the division of the same into separate territories; and have ordained for each of them a constitution, a plan of temporary government, whereby the civil and political rights of the inhabitants are regulated, and the rights of conscience and other natural rights are protected.
The power to make all needful regulations, includes the power to determine what regulations are needful; and if a regulation prohibiting slavery within any territory of the United States be, as it has been, deemed needful, Congress possess the power to make the same, and, moreover, to pass all laws necessary to carry this power into execution.
