"We are now far into this fifth year since a policy was initiated with the avowed object and confident promise of putting an end to slavery agitation. Under the operation of that policy, that agitation has not only not ceased, but has constantly augmented. In my opinion, it will not cease until a crisis shall have been reached and passed. 'A house divided against itself cannot stand.' I believe this country cannot endure permanently half slave and half free. I do not expect the Union to be dissolved--I do not expect the house to fall--but I do expect it will cease to be divided. It will become all one thing or all the other. Either the opponents of slavery will arrest the further spread of it and place it where the public mind shall rest in the belief that it is in the course of ultimate extinction, or its advocates will push it forward until it shall become alike lawful in all the States, old as well as new, North as well as South." This, at the time, was a bold utterance, and, it was believed by many, would imperil Mr. Lincoln's chances for election. Mr. Blaine in his "Twenty Years of Congress," says: "Mr. Lincoln had been warned by intimate friends to whom he had communicated the contents of his speech in advance of its delivery, that he was treading on dangerous ground, that he would be misinterpreted as a disunionist, and that he might fatally damage the Republican party by making its existence synonymous with a destruction of the Government." The opening speech of Senator Douglas at Chicago a few days later-- sounding the keynote of his campaign--was in the main an arraignment of his opponent for an attempt to precipitate an internecine conflict, and array in deadly hostility the North against the South. He said: "In other words, Mr. Lincoln advocates boldly and clearly a war of sections, a war of the North against the South, of the free States against the slave States--a war of extermination--to be continued relentlessly until the one or the other shall be subdued, and all the States shall either become free or become slave."
