Physically speaking, we cannot separate. We can not remove our respective sections from each other, nor build an impassable wall between them. A husband and wife may be divorced, and go out of the presence, and beyond the reach of each other; but the different parts of our country cannot do this. They cannot but remain face to face; and intercourse, either amicable or hostile, must continue between them. Is it possible, then, to make that intercourse more advantageous or more satisfactory, after separation than before? Can aliens make treaties easier than friends can make laws? Can treaties be more faithfully enforced between aliens than laws can among friends? Suppose you go to war, you cannot fight always; and when, after much loss on both sides, and no gain on either, you cease fighting, the identical old questions, as to terms of intercourse, are again upon you.
We know that Abraham Lincoln was one who did believe in "state rights." He states also in the first inaugural address, " That the maintenance inviolate of the rights of the States, and especially the right of each State to order and control its own domestic institutions according to its own judgment exclusively, is essential to that balance of power on which the perfection and endurance of our political fabric depend; and we denounce the lawless invasion by armed force of the soil of any State or Territory, no matter what pretext, as among the gravest of crimes." However, the issues if slavery had become far more important than to respect the rights of the states. He knew he could not just seperate the north and the south and allow the south to continue with the inequalities of slavery. It would be impossible to run a successful United States that way. I choose this passage because I like the correlation he makes between the states and a husband and wife.
