The party that had nominated Lincoln for the Senate was not prepared to endorse his restriction of the coming struggle to the single issue of the slavery question. His friends dreaded the result of his uncompromising frankness, while politicians quite generally condemned it. Even so stanch a friend as Leonard Swett, whose devotion to Lincoln never wavered throughout his whole career, shared these apprehensions. Says Mr. Swett: "The first ten lines of that speech defeated him. The sentiment of the 'house divided against itself' seemed wholly inappropriate. It was a speech made at the commencement of a campaign, and apparently made for the campaign. Viewing it in this light alone, nothing could have been more unfortunate or inappropriate. It was saying the wrong thing first; yet he felt that it was an abstract truth, and that standing by the speech would ultimately find him in the right place. I was inclined at the time to believe these words were hastily and inconsiderately uttered; but subsequent facts have convinced me they were deliberate and had been well matured."

A few days after the delivery of this speech, a gentleman named Dr. Long called on Lincoln and gave him a foretaste of the remarks he was to hear during the next few months. "Well, Lincoln," said he, "that foolish speech of yours will kill you—will defeat you in this contest, and probably for all offices for all time to come. I am sorry, sorry, very sorry. I wish it was wiped out of existence. Don't you wish so too?" Laying down the pen with which he had been writing, and slowly raising his head and adjusting his spectacles, Lincoln replied: "Well, Doctor, if I had to draw a pen across and erase my whole life from existence, and I had one poor gift or choice left as to what I should save from the wreck, I should choose that speech, and leave it to the world unerased."

The Senatorial campaign was now well begun. Douglas opened it by a speech at Chicago on the 9th of July. Lincoln was present, and on the next evening spoke in reply from the same place—the balcony of the Tremont House. A week later Douglas spoke at Bloomington, with Lincoln again in the audience. The notion of a joint discussion seems to have originated with Lincoln, who on the 24th of July addressed a note to Douglas as follows:

HON. S.A. DOUGLAS—My Dear Sir:—Will it be agreeable to you to make an arrangement for you and myself to divide time, and address the same audiences during the present canvass? Mr. Judd, who will hand you this, is authorized to receive your answer, and, if agreeable to you, to enter into the terms of such arrangement. Your obedient servant, A. LINCOLN.

The result of this proposal was an agreement that there should be a joint discussion between the two candidates in each of the seven Congressional districts in which they had not both already been heard. Places were named and dates fixed extending to the middle of October. It was agreed that the opening speech on each occasion should occupy one hour; the reply, one hour and a half; the close, half an hour; and that Mr. Douglas should have the first and last voice in four of the seven meetings.

The champions who were thus to enter the lists in a decisive trial of forensic strength and skill are forcibly contrasted by Mr. Speed, who says: "They were the respective leaders of their parties in the State. They were as opposite in character as they were unlike in their persons. Lincoln was long and ungainly; Douglas was short and compact. Douglas, in all elections, was the moving spirit and manager. He was content with nothing short of a blind submission to himself. He could not tolerate opposition to his will within his party organization. He held the reins and controlled the movements of the Democratic chariot. With a large State majority, with many able and ambitious men in it, he stepped to the front in his youth and held his place till his death. Lincoln, on the other hand, shrank from any controversy with his friends. His party being in a minority in the State, he was forced to the front because his friends thought he was the only man with whom they could win. In a canvass his friends had to do all the management. He knew nothing of how to reach the people except by addressing their reason. If the situation had been reversed—Lincoln representing the majority and Douglas the minority—I think it most likely Lincoln would never have had the place. He had no heart for a fight with friends."

The Hon. James G. Blaine has given a masterly description and analysis of the comparative powers of the two illustrious debaters. Douglas, says Mr. Blaine, "was everywhere known as a debater of singular skill. His mind was fertile in resources. He was a master of logic. No man perceived more quickly than he the strength or the weakness of an argument, and no one excelled him in the use of sophistry and fallacy. Where he could not elucidate a point to his own advantage, he would fatally becloud it for his opponent. In that peculiar style of debate which in intensity resembles a physical combat, he had no equal. He spoke with extraordinary readiness. There was no halting in his phrase. He used good English, terse, vigorous, pointed. He disregarded the adornments of rhetoric—rarely used a simile. He was utterly destitute of humor, and had slight appreciation of wit. He never cited historical precedents except from the domain of American politics. Inside that field his knowledge was comprehensive, minute, critical; beyond it his learning was limited. He was not a reader. His recreations were not in literature. In the whole range of his voluminous speaking, it would be difficult to find either a line of poetry or a classical allusion. But he was by nature an orator, and by long practice a debater. He could lead a crowd almost irresistibly to his own conclusions. He could, if he wished, incite a mob to desperate deeds. He was, in short, an able, audacious, almost unconquerable opponent in public discussion. It would have been impossible to find any man of the same type able to meet him before the people of Illinois. Whoever attempted it would probably have been destroyed in the first encounter. But the man who was chosen to meet him, who challenged him to the combat, was radically different in every phase of character. Scarcely could two men be more unlike in mental and moral constitution than Abraham Lincoln and Stephen A. Douglas. Lincoln was calm and philosophic. He loved the truth for the truth's sake. He would not argue from a false premise, or be deceived himself or deceive others by a false conclusion. He had pondered deeply on the issues which aroused him to action. He had given anxious thought to the problems of free government, and to the destiny of the Republic. He had marked out a path of duty for himself, and he walked it fearlessly. His mental processes were slower but more profound than those of Douglas. He did not seek to say merely the thing which was best for that day's debate, but the thing which would stand the test of time and square itself with eternal justice. He wished nothing to appear white unless it was white. His logic was severe and faultless. He did not resort to fallacy, and could detect it in his opponent and expose it with merciless directness. He had an abounding sense of humor, and always employed it in illustration of his argument—but never for the mere sake of provoking merriment. In this respect he had the wonderful aptness of Franklin. He often taught a great truth with the felicitous brevity of an Aesop fable. His words did not flow in an impetuous torrent, as did those of Douglas; but they were always well chosen, deliberate and conclusive."

Mr. Arnold, in the course of an extended comparison, says: "At the time of these discussions, both Lincoln and Douglas were in the full maturity of their powers. Douglas was forty-five and Lincoln forty-nine years of age. Physically and mentally, they were as unlike as possible. Douglas was short, not much more than five feet high, with a large head, massive brain, broad shoulders, a wide, deep chest, and features strongly marked. He impressed every one, at first sight, as a strong, sturdy, resolute, fearless man. Lincoln's herculean stature has already been described. A stranger who listened to him for five minutes would say: 'This is a kind, genial, sincere, genuine man; a man you can trust, plain, straightforward, honest, and true.' If this stranger were to hear him make a speech, he would be impressed with his clear good sense, by his wit and humor, by his general intelligence, and by the simple, homely, but pure and accurate language he used. In his long residence at Washington, Douglas had acquired the bearing and manners of a gentleman and a man of the world. But he was always a fascinating and attractive man, and always and everywhere personally popular. He had been for years carefully and thoroughly trained on the stump, in Congress, and in the Senate, to meet in debate the ablest speakers in the State and Nation. For years he had been accustomed to meet on the floor of the Capitol the leaders of the old Whig and Free-soil parties. Among them were Webster and Seward, Fessenden and Crittenden, Chase, Trumbull, Hale and others of nearly equal eminence; and his enthusiastic friends insisted that never, either in single conflict or when receiving the assault of the senatorial leaders of a whole party, had he been discomfited. His style was bold, vigorous, and aggressive; at times even defiant. He was ready, fluent, fertile in resources, familiar with national and party history, severe in denunciation, and he handled with skill nearly all the weapons of debate. His iron will and restless energy, together with great personal magnetism, made him the idol of his friends and party. His long, brilliant, and almost universally successful career, gave him perfect confidence in himself, and at times he was arrogant and overbearing.... Lincoln also was a thoroughly trained speaker. He had met successfully, year after year, at the bar and on the stump, the ablest men of Illinois and the Northwest, including Lamborn, Stephen T. Logan, John Calhoun, and many others. He had contended, in generous emulation, with Hardin, Baker, Logan, and Browning; and had very often met Douglas, a conflict with whom he always courted rather than shunned. His speeches, as we read them to-day, show a more familiar knowledge of the slavery question than those of any other statesman of our country. This is especially true of the Peoria speech and the Cooper Institute speech. Lincoln was powerful in argument, always seizing the strong points, and demonstrating his propositions with a clearness and logic approaching the certainty of mathematics. He had, in wit and humor, a great advantage over Douglas. Then he had the better temper; he was always good humored, while Douglas, when hard pressed, was sometimes irritable. Douglas perhaps carried away the more popular applause; Lincoln made the deeper and more lasting impression. Douglas did not disdain an immediate ad captandum triumph; while Lincoln aimed at permanent conviction. Sometimes, when Lincoln's friends urged him to raise a storm of applause, which he could always do by his happy illustrations and amusing stories, he refused, saying, 'The occasion is too serious; the issues are too grave. I do not seek applause, or to amuse the people, but to convince them.' It was observed in the canvass that while Douglas was greeted with the loudest cheers, when Lincoln closed the people seemed serious and thoughtful, and could be heard all through the crowd, gravely and anxiously discussing the subjects on which he had been speaking."

Soon after the arrangements for the debate had been made, Senator Douglas visited Alton, Illinois. A delegation of prominent Democrats there paid their respects to him, and during the conversation one of them congratulated Douglas on the easy task he would have in defeating Lincoln; at the same time expressing surprise at the champion whom he had selected. Douglas replied: "Gentlemen, you do not know Mr. Lincoln. I have known him long and well, and I know that I shall have anything but an easy task. I assure you I would rather meet any other man in the country than Abraham Lincoln." This was Douglas's mature opinion of the man of whom, years before, he had said, in his characteristic way: "Of all the d——d Whig rascals about Springfield, Abe Lincoln is the ablest and honestest." On another occasion, Douglas said: "I have known Lincoln for nearly twenty-five years. There were many points of sympathy between us when we first got acquainted. We were both comparatively boys, and both struggling with poverty in a strange land. I was a school-teacher in the town of Winchester, and he a flourishing grocery-keeper in the town of Salem. He was more successful in his occupation than I was in mine, and hence more fortunate in the world's goods. Lincoln is one of those peculiar men who perform with admirable skill everything they undertake. I made as good a school-teacher as I could, and when a cabinet-maker I made as good bedsteads and tables as I could—although my old boss says that I succeeded better with bureaus and secretaries than with anything else. But I believe that Lincoln was always more successful in business than I, for his business enabled him to get into the Legislature. I met him there, however, and had a sympathy with him because of the up-hill struggle we both had had in life. He was then just as good at telling an anecdote as now. He could beat any of the boys in wrestling or running a foot-race, in pitching quoits or pitching a copper; and the dignity and impartiality with which he presided at a horse-race or fist-fight excited the admiration and won the praise of everybody that was present. I sympathized with him because he was struggling with difficulties, and so was I. Mr. Lincoln served with me in the Legislature of 1836; then we both retired, and he subsided, or became submerged, and was lost sight of as a public man for some years. In 1846, when Wilmot introduced his celebrated proviso, and the Abolition tornado swept over the country, Lincoln again turned up as a Member of Congress from the Sangamon district. I was then in the Senate of the United States, and was glad to welcome my old friend."

Lincoln, in a speech delivered two years before the joint debate, had spoken thus of Senator Douglas: "Twenty-two years ago, Judge Douglas and I first became acquainted; we were both young then—he a trifle younger than I. Even then, we were both ambitious—I perhaps quite as much as he. With me, the race of ambition has been a failure—a flat failure; with him, it has been one of splendid success. His name fills the nation, and is not unknown even in foreign lands. I affect no contempt for the high eminence he has reached; so reached that the oppressed of my species might have shared with me in the elevation, I would rather stand on that eminence than wear the richest crown that ever pressed a monarch's brow."
