The first thing that must be grasped about it is the total difference of view which now existed between North and South in regard to the very nature of their connection. The divergence had taken place so completely and in the main so quietly that each side now realised with surprise and indignation that the other held an opposite opinion. In the North the Union was regarded as constituting a permanent and unquestionable national unity from which it was flat rebellion for a State or any other combination of persons to secede. In the South the Union appeared merely as a peculiarly venerable treaty of alliance, of which the dissolution would be very painful, but which left each State a sovereign body with an indefeasible right to secede if in the last resort it judged that the painful necessity had come. In a few border States there was division and doubt on this subject, a fact which must have helped to hide from each side the true strength of opinion on the other. But, setting aside these border States, there were in the North some who doubted whether it was expedient to fight for the Union, but none of any consequence who doubted that it was constitutionally correct; and there were in the South men who insisted that no occasion to secede had arisen, but these very men, when outvoted in their States, maintained most passionately the absolute right of secession. The two sides contended for two contrary doctrines of constitutional law. It is natural when parties are disputing over a question of political wisdom and of moral right that each should claim for its contention if possible the sanction of acknowledged legal principle. So it was with the parties to the English Civil War, and the tendency to regard matters from a legal point of view is to this day deeply engrained in the mental habits of America. But North and South were really divided by something other than legal opinion, a difference in the objects to which their feelings of loyalty and patriotism were directed. This difference found apt expression in the Cabinet of President Buchanan, who of course remained in office between the election of Lincoln in November and his inauguration in March. General Cass of Michigan had formerly stood for the Presidency with the support of the South, and he held Cabinet office now as a sympathiser with the South upon slavery, but he was a Northerner. "I see how it is," he said to two of his colleagues; "you are a Virginian, and you are a South Carolinian; I am not a Michigander, I am an American."
