"But our conversations, like so many about the war, focused on people and battles, not on why the confrontation happened in the first place. There remains enormous denial over the fact that the central cause of the war was our national disagreement about race and slavery, not states' rights or anything else."
Really E.J.? Just slavery? Then why did the Civil War not break out when the slave trade was Constitutionally outlawed in 1808? Why did it not break out at the time of the Missouri Compromise? The Kansas Nebraska Act? The Compromise of 1850? The Civil War was kept in check because the political systems at the time of these great compromises was resilient enough to accommodate them. By the election of 1860, that system had lost its resilience. Was the Civil War caused by slavery? Of course. Was it caused only by slavery? Not by a long shot.

"I would save the Union. I would save it the shortest way under the Constitution. The sooner the national authority can be restored; the nearer the Union will be "the Union as it was." If there be those who would not save the Union, unless they could at the same time save slavery, I do not agree with them. If there be those who would not save the Union unless they could at the same time destroy slavery, I do not agree with them. My paramount object in this struggle is to save the Union, and is not either to save or to destroy slavery. If I could save the Union without freeing any slave I would do it, and if I could save it by freeing all the slaves I would do it; and if I could save it by freeing some and leaving others alone I would also do that. What I do about slavery, and the colored race, I do because I believe it helps to save the Union; and what I forbear, I forbear because I do not believe it would help to save the Union. I shall do less whenever I shall believe what I am doing hurts the cause, and I shall do more whenever I shall believe doing more will help the cause. I shall try to correct errors when shown to be errors; and I shall adopt new views so fast as they shall appear to be true views. I have here stated my purpose according to my view of official duty; and I intend no modification of my oft-expressed personal wish that all men everywhere could be free."
