"Under that principle we have become, from a feeble nation, the most powerful on the face of the earth; and if we only adhere to that principle, we can go forward increasing in territory, in power, in strength and in glory, until the Republic of America shall be the North Star that shall guide the friends of freedom throughout the civilized world. * * * I believe that this new doctrine preached by Mr. Lincoln and his party will dissolve the Union if it succeeds. They are trying to array all the Northern States in one body against the South, to excite a sectional war between the free States and the slave States, in order that the one or the other may be driven to the wall." When the applause subsided, Lincoln rose to reply. Addressing himself first to the personal matters contained in Douglas' speech, he denied the charge of a secret bargain between himself and Trumbull dividing the two seats in the Senate between them. "All I have to say upon that subject is, that I think no man--not even Judge Douglas--can prove it, because it is not true." He denied utterly that he had anything to do with the Republican platform drafted by the party leaders in 1854, having refused to meet with the committee or take any part in the organization. "I have no means," he said, " of totally disproving such charges as this. I cannot prove a negative; but have a right to say that, when he makes an affirmative charge, he must offer some proof of its truth. Douglas' argument about 'perfect social and political equality with the negro' is but a specious and fantastic arrangement of words by which a man can prove a horse chestnut to be a chestnut horse. I will say here, while upon the subject, that I have no purpose directly or indirectly, to interfere with the institution of slavery in the States where it exists. I believe I have no lawful right to do so. I have no purpose to introduce political and social equality between the white and black races. There is a physical difference between the two, which in my judgement will forever forbid their living together upon a footing of perfect equality; and inasmuch as it becomes a necessity that there must be a difference, I am in favor of the race to which I belong having the superior position. I agree with Judge Douglas that the negro is not my equal in many respects--certainly not in color--perhaps not in moral or intellectual endowment. But in the right to eat the bread, without the leave of anybody else, which his own hand earns, he is my equal and the equal of Judge Douglas and the equal of every living man. * * *
