"This speech," says Mr. Arnold, "was the text of the great debate between Lincoln and Douglas." It states the question in the United States as between slavery and freedom, with very great strength and plainness, and lays down the principles that apply to it with equal power. It had been carefully prepared beforehand, as a manifesto for which the times were ripe. For the first time it placed the speaker publicly upon advanced anti-slavery ground; and it is by no means improbable that in taking that ground, Mr. Lincoln had some secret conscious or half conscious feeling not only that he was marking out the place that his party must occupy in the coming struggle, but that in doing so he assumed the place of standard-bearer. He explained the doctrines of the Nebraska Act, and the Dred Scott decision; showed how the Democratic party had become ranged on the side of slavery; explained how the result of the Dred Scott decision, together with the indifferent policy so jauntily vaunted by Douglas, of "not caring whether slavery were voted up or down," must result in a final victory of slavery; and showed how Mr. Douglas' doctrines permitted and invited that final victory. And having thus showed "where we are, and whither we are tending," he ended with a solemn but cheering exhortation, "what to do and how to do it." "The result," he said, "is not doubtful. We shall not fail, if we stand firm we shall not fail. Wise counsels may accelerate, or mistakes delay it, but sooner or later, THE VICTORY IS SURE TO COME." That is the language, not of a party politician, recommending expedient nostrums, but of a statesman who feels profoundly that his people are sound at heart, and will assuredly one day do full justice; who proclaims in advance the eternal victory of the right side, and boldly calls on all who hear him to advance up to the line of their own consciences. Before delivering this speech, Mr. Lincoln locked himself into a room with his partner, Mr. Herndon, and read him the first paragraph of the speech. "What do you think of it?" said he. Herndon answered, "I think it is all true, but I doubt whether it is good policy to say it now." Mr. Lincoln replied, "That makes no difference; it is the truth, and the nation is entitled to it." This was both honest and politic; for if the ground of principle as against expediency had not been taken, there was none left to oppose the reasonings of Mr. Douglas, which were extremely adroit, and so far as expediency admitted, indeed unanswerable.
