[T]he one unforgivable sin, according to dominant Southern public opinion, was moral condemnation of slavery. - Harry V. Jaffa

With this, we are introduced to a unique American contribution to political science: dual federalism and dual sovereignty. The states are sovereign within the spheres of the powers that are reserved to them by the Constitution. They are not sovereign in those things that are delegated to the United States as a whole.

Alexander Hamilton Stephens' Constitutional View of the War Between the States, which was and remains probably the best defense of the Confederate cause. It is all about states' rights, and the defense of the minority against the tyranny of the numerical majority, although the "silent minority", the four million slaves, are never counted. It is substantially the book that Calhoun would have written had he been alive to do so. Stephens, who was Vice President of the Confederacy, had also been widely known, north and south, as one of the intellectual luminaries of his time.

But he did want to see to it that loyal slave owners were not expropriated by his emancipation policy. But he couldn't get the Congress to adopt it. He couldn't get any Representatives, and people from Kentucky, or Missouri, or the border states to vote for it, and so he failed. This is the message to Congress which ended with those wonderful words, “Gentlemen of the Congress, we cannot escape history. The fiery trial through which we pass will light us down in honor or dishonor to the latest generation. We shall nobly save or meanly lose the last, best hope of Earth.” Well, it failed.
