It was in January, 1854, that the accidents of a Senate debate threw into Congress and upon the country the firebrand of the repeal of the Missouri Compromise. The repeal was not consummated till the month of May; and from May until the autumn elections the flame of acrimonious discussion ran over the whole country like a wild fire. There is no record that Mr. Lincoln took any public part in the discussion until the month of September, but it is very clear that he not only carefully watched its progress, but that he studied its phases of development, its historical origins, and its legal bearings with close industry, and gathered from party literature and legislative documents a harvest of substantial facts and data, rather than the wordy campaign phrases and explosive epithets with which more impulsive students and speakers were content to produce their oratorical effects. Here we may again quote Mr. Lincoln's exact written statement of the manner in which he resumed his political activity:

"In the autumn of that year [1854] he took the stump, with no broader practical aim or object than to secure, if possible, the reëlection of Hon. Richard Yates to Congress. His speeches at once attracted a more marked attention than they had ever before done. As the canvass proceeded he was drawn to different parts of the State, outside of Mr. Yates's district. He did not abandon the law, but gave his attention by turns to that and politics. The State Agricultural Fair was at Springfield that year, and Douglas was announced to speak there."

The new question had created great excitement and uncertainty in Illinois politics, and there were abundant signs that it was beginning to break up the organization of both the Whig and the Democratic parties. This feeling brought together at the State fair an unusual number of local leaders from widely scattered counties, and almost spontaneously a sort of political tournament of speech-making broke out. In this Senator Douglas, doubly conspicuous by his championship of the Nebraska Bill in Congress, was expected to play the leading part, while the opposition, by a common impulse, called upon Lincoln to answer him. Lincoln performed the task with such aptness and force, with such freshness of argument, illustrations from history, and citations from authorities, as secured him a decided oratorical triumph, and lifted him at a single bound to the leadership of the opposition to Douglas's propagandism. Two weeks later, Douglas and Lincoln met at Peoria in a similar debate, and on his return to Springfield Lincoln wrote out and printed his speech in full.

The reader who carefully examines this speech will at once be impressed with the genius which immediately made Mr. Lincoln a power in American politics. His grasp of the subject is so comprehensive, his statement so clear, his reasoning so convincing, his language so strong and eloquent by turns, that the wonderful power he manifested in the discussions and debates of the six succeeding years does not surpass, but only amplifies this, his first examination of the whole brood of questions relating to slavery precipitated upon the country by Douglas's repeal. After a searching history of the Missouri Compromise, he attacks the demoralizing effects and portentous consequences of its repeal.

"This declared indifference," he says, "but, as I must think, covert real zeal for the spread of slavery, I cannot but hate. I hate it because of the monstrous injustice of slavery itself. I hate it because it deprives our republican example of its just influence in the world; enables the enemies of free institutions, with plausibility, to taunt us as hypocrites; causes the real friends of freedom to doubt our sincerity; and especially because it forces so many good men among ourselves into an open war with the very fundamental principles of civil liberty, criticizing the Declaration of Independence, and insisting that there is no right principle of action but self-interest.... Slavery is founded in the selfishness of man's nature—opposition to it in his love of justice. These principles are an eternal antagonism, and when brought into collision so fiercely as slavery extension brings them, shocks and throes and convulsions must ceaselessly follow. Repeal the Missouri Compromise, repeal all compromises, repeal the Declaration of Independence, repeal all past history, you still cannot repeal human nature. It still will be the abundance of man's heart that slavery extension is wrong, and out of the abundance of his heart his mouth will continue to speak."

With argument as impetuous, and logic as inexorable, he disposes of Douglas's plea of popular sovereignty:

"Here, or at Washington, I would not trouble myself with the oyster laws of Virginia, or the cranberry laws of Indiana. The doctrine of self-government is right—absolutely and eternally right—but it has no just application as here attempted. Or perhaps I should rather say, that whether it has such application depends upon whether a negro is not or is a man. If he is not a man, in that case, he who is a man may, as a matter of self-government, do just what he pleases with him. But if the negro is a man, is it not to that extent a total destruction of self-government to say that he too shall not govern himself? When the white man governs himself, that is self-government; but when he governs himself and also governs another man, that is more than self-government—that is despotism.... I particularly object to the new position which the avowed principle of this Nebraska law gives to slavery in the body politic. I object to it because it assumes that there can be moral right in the enslaving of one man by another. I object to it as a dangerous dalliance for a free people—a sad evidence that, feeling prosperity, we forget right; that liberty, as a principle, we have ceased to revere.... Little by little, but steadily as man's march to the grave, we have been giving up the old for the new faith. Near eighty years ago we began by declaring that all men are created equal; but now, from that beginning, we have run down to the other declaration, that for some men to enslave others is a 'sacred right of self-government.' These principles cannot stand together. They are as opposite as God and Mammon."

If one compares the serious tone of this speech with the hard cider and coon-skin buncombe of the Harrison campaign of 1840, and its lofty philosophical thought with the humorous declamation of the Taylor campaign of 1848, the speaker's advance in mental development at once becomes apparent. In this single effort Mr. Lincoln had risen from the class of the politician to the rank of the statesman. There is a well-founded tradition that Douglas, disconcerted and troubled by Lincoln's unexpected manifestation of power in the Springfield and Peoria debates, sought a friendly interview with his opponent, and obtained from him an agreement that neither one of them would make any further speeches before the election.

The local interest in the campaign was greatly heightened by the fact that the term of Douglas's Democratic colleague in the United States Senate was about to expire, and that the State legislature to be elected would have the choosing of his successor. It is not probable that Lincoln built much hope upon this coming political chance, as the Democratic party had been throughout the whole history of the State in decided political control. It turned out, nevertheless, that in the election held on November 7, an opposition majority of members of the legislature was chosen, and Lincoln became, to outward appearances, the most available opposition candidate. But party disintegration had been only partial. Lincoln and his party friends still called themselves Whigs, though they could muster only a minority of the total membership of the legislature. The so-called Anti-Nebraska Democrats, opposing Douglas and his followers, were still too full of traditional party prejudice to help elect a pronounced Whig to the United States Senate, though as strongly "Anti-Nebraska" as themselves. Five of them brought forward, and stubbornly voted for, Lyman Trumbull, an Anti-Nebraska Democrat of ability, who had been chosen representative in Congress from the eighth Illinois District in the recent election. On the ninth ballot it became evident to Lincoln that there was danger of a new Democratic candidate, neutral on the Nebraska question, being chosen. In this contingency, he manifested a personal generosity and political sagacity far above the comprehension of the ordinary smart politician. He advised and prevailed upon his Whig supporters to vote for Trumbull, and thus secure a vote in the United States Senate against slavery extension. He had rightly interpreted both statesmanship and human nature. His personal sacrifice on this occasion contributed essentially to the coming political regeneration of his State; and the five Anti-Nebraska Democrats, who then wrought his defeat, became his most devoted personal followers and efficient allies in his own later political triumph, which adverse currents, however, were still to delay to a tantalizing degree. The circumstances of his defeat at that critical stage of his career must have seemed especially irritating, yet he preserved a most remarkable equanimity of temper. "I regret my defeat moderately," he wrote to a sympathizing friend, "but I am not nervous about it."

We may fairly infer that while Mr. Lincoln was not "nervous," he was nevertheless deeply impressed by the circumstance as an illustration of the grave nature of the pending political controversy. A letter written by him about half a year later to a friend in Kentucky, is full of such serious reflection as to show that the existing political conditions in the United States had engaged his most profound thought and investigation.
