The Southern States, standing on the basis of the Constitution, have a right to demand this act of justice from the States of the North. Should it be refused, then the Constitution, to which all the States are parties, will have been willfully violated by one portion of them in a provision essential to the domestic security and happiness of the remainder. In that event the injured States, after having first used all peaceful and constitutional means to obtain redress, would be justified in revolutionary resistance to the Government of the Union. I have purposely confined my remarks to revolutionary resistance, because it has been claimed within the last few years that any State, whenever this shall be its sovereign will and pleasure, may secede from the Union in accordance with the Constitution and without any violation of the constitutional rights of the other members of the Confederacy; that as each became parties to the Union by the vote of its own people assembled in convention, so any one of them may retire from the Union in a similar manner by the vote of such a convention. In order to justify secession as a constitutional remedy, it must be on the principle that the Federal Government is a mere voluntary association of States, to be dissolved at pleasure by any one of the contracting parties. If this be so, the Confederacy is a rope of sand, to be penetrated and dissolved by the first adverse wave of public opinion in any of the States. In this manner our thirty-three States may, resolve themselves into as many petty, jarring, and hostile republics, each one retiring from the Union without responsibility whenever any sudden excitement might impel them to such a course. By this process a Union might be entirely broken into fragments in a few weeks which cost our forefathers many years of toil, privation, and blood to establish.
