As to the vaunted popular sovereignty principle, Lincoln declared it "the most arrant Quixotism that was ever enacted before a community.... Does he mean to say that he has been devoting his life to securing to the people of the Territories the right to exclude slavery from the Territories? If he means so to say, he means to deceive; because he and every one knows that the decision of the Supreme Court, which he approves and makes especial ground of attack upon me for disapproving, forbids the people of a Territory to exclude slavery. This covers the whole ground from the settlement of a Territory till it reaches the degree of maturity entitling it to form a State constitution. So far as all that ground is concerned, the Judge is not sustaining popular sovereignty, but absolutely opposing it. He sustains the decision which declares that the popular will of the Territories has no constitutional power to exclude slavery during their territorial existence."
By no means the least interesting of the many points touched in these debates is Lincoln's own estimate of the probable duration of slavery, or rather of the least possible period in which "ultimate extinction" could be effected, even under the most favorable circumstances.
Lincoln-Douglas Debates, p. 157.
Now, at this day in the history of the world [said he, in the Charleston debate], we can no more foretell where the end of this slavery agitation will be than we can see the end of the world itself. The Nebraska-Kansas bill was introduced four years and a half ago, and if the agitation is ever to come to an end, we may say we are four years and a half nearer the end. So too we can say we are four years and a half nearer the end of the world; and we can just as clearly see the end of the world as we can see the end of this agitation. The Kansas settlement did not conclude it. If Kansas should sink to-day, and leave a great vacant space in the earth's surface, this vexed question would still be among us. I say then there is no way of putting an end to the slavery agitation amongst us, but to put it back upon the basis where our fathers placed it, no way but to keep it out of our new Territories—to restrict it forever to the old States where it now exists. Then the public mind will rest in the belief that it is in the course of ultimate extinction. That is one way of putting an end to the slavery agitation.
The other way is for us to surrender and let Judge Douglas and his friends have their way and plant slavery over all the States; cease speaking of it as in any way a wrong; regard slavery as one of the common matters of property and speak of negroes as we do of our horses and cattle. But while it drives on in its state of progress as it is now driving, and as it has driven for the last five years, I have ventured the opinion, and I say to-day that we will have no end to the slavery agitation until it takes one turn or the other. I do not mean to say that when it takes a turn towards ultimate extinction it will be in a day, nor in a year, nor in two years. I do not suppose that in the most peaceful way ultimate extinction would occur in less than a hundred years at least; but that it will occur in the best way for both races, in God's own good time, I have no doubt.
But the one dominating characteristic of Lincoln's speeches is their constant recurrence to broad and enduring principles, their unremitting effort to lead public opinion to loftier and nobler conceptions of political duty; and nothing in his career stamps him so distinctively an American as his constant eulogy and defense of the philosophical precepts of the Declaration of Independence. The following is one of his indictments of his political opponents on this point:
Lincoln-Douglas Debates, p. 225.
At Galesburg the other day, I said, in answer to Judge Douglas, that three years ago there never had been a man, so far as I knew or believed, in the whole world, who had said that the Declaration of Independence did not include negroes in the term "all men." I re-assert it to-day. I assert that Judge Douglas and all his friends may search the whole records of the country, and it will be a matter of great astonishment to me if they shall be able to find that one human being three years ago had ever uttered the astounding sentiment that the term "all men" in the Declaration did not include the negro. Do not let me be misunderstood. I know that more than three years ago there were men who, finding this assertion constantly in the way of their schemes to bring about the ascendency and perpetuation of slavery, denied the truth of it. I know that Mr. Calhoun and all the politicians of his school denied the truth of the Declaration. I know that it ran along in the mouth of some Southern men for a period of years, ending at last in that shameful though rather forcible declaration of Pettit, of Indiana, upon the floor of the United States Senate, that the Declaration of Independence was in that respect "a self-evident lie" rather than a self-evident truth. But I say, with a perfect knowledge of all this hawking at the Declaration without directly attacking it, that three years ago there never had lived a man who had ventured to assail it in the sneaking way of pretending to believe it and then asserting it did not include the negro. I believe the first man who ever said it was Chief-Justice Taney in the Dred Scott case, and the next to him was our friend, Stephen A. Douglas. And now it has become the catchword of the entire party. I would like to call upon his friends everywhere to consider how they have come in so short a time to view this matter in a way so entirely different from their former belief; to ask whether they are not being borne along by an irresistible current, whither they know not?
In the joint debates, however, argument and oratory were both hampered by the inexorable limit of time. For the full development of his thought, the speeches Lincoln made separately at other places afforded him a freer opportunity. A quotation from his language on one of these occasions is therefore here added, as a better illustration of his style and logic, where his sublime theme carried him into one of his more impassioned moods:
The Declaration of Independence was formed by the representatives of American liberty from thirteen States of the Confederacy, twelve of which were slave-holding communities. We need not discuss the way or the reason of their becoming slave-holding communities. It is sufficient for our purpose that all of them greatly deplored the evil and that they placed a provision in the Constitution which they supposed would gradually remove the disease by cutting off its source. This was the abolition of the slave trade. So general was the conviction, the public determination, to abolish the African slave trade, that the provision which I have referred to as being placed in the Constitution declared that it should not be abolished prior to the year 1808. A constitutional provision was necessary to prevent the people, through Congress, from putting a stop to the traffic immediately at the close of the war. Now if slavery had been a good thing, would the fathers of the republic have taken a step calculated to diminish its beneficent influences among themselves, and snatch the boon wholly from their posterity? These communities, by their representatives in old Independence Hall, said to the whole world of men: "We hold these truths to be self-evident: that all men are created equal; that they are endowed by their Creator with certain inalienable rights; that among these are life, liberty, and the pursuit of happiness." This was their majestic interpretation of the economy of the Universe. This was their lofty, and wise, and noble understanding of the justice of the Creator to his creatures. Yes, gentlemen, to all his creatures, to the whole great family of man. In their enlightened belief, nothing stamped with the Divine image and likeness was sent into the world to be trodden on and degraded, and imbruted by its fellows. They grasped not only the whole race of man then living, but they reached forward and seized upon the farthest posterity. They erected a beacon to guide their children, and their children's children, and the countless myriads who should inhabit the earth in other ages. Wise statesmen as they were, they knew the tendency of prosperity to breed tyrants, and so they established these great self-evident truths, that when in the distant future some man, some faction, some interest, should set up the doctrine that none but rich men, or none but white men, or none but Anglo-Saxon white men, were entitled to life, liberty, and the pursuit of happiness, their posterity might look up again to the Declaration of Independence and take courage to renew the battle which their fathers began, so that truth and justice and mercy and all the humane and Christian virtues might not be extinguished from the land; so that no man would hereafter dare to limit and circumscribe the great principles on which the temple of liberty was being built.
