1. On the expansion of slavery:
There is a natural disgust in the minds of nearly all white people to the idea of indiscriminate amalgamation of the white and black races … A separation of the races is the only perfect preventive of amalgamation, but as an immediate separation is impossible, the next best thing is to keep them apart where they are not already together. If white and black people never get together in Kansas, they will never mix blood in Kansas …
2. On shipping blacks back to Africa:
In the language of Mr. Jefferson, uttered many years ago, “It is still in our power to direct the process of emancipation, and deportation, peaceably, and in such slow degrees, as that the evil will wear off insensibly; and in their places be, pari passu [on an equal basis], filled up by free white laborers.”
3. On outlawing slavery in the south (before the rebellion).
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, and I have no inclination to do so.
4. On equality:
I have no purpose to introduce political and social equality between the white and black races. There is physical difference between the two which, in my judgment, will probably forever forbid their living together upon the footing of perfect equality, and inasmuch as it becomes a necessity that there must be a difference, I, as well as Judge Douglas, am in favor of the race to which I belong having the superior position.
5. On inter-racial marriage:
Our republican system was meant for a homogeneous people. As long as blacks continue to live with the whites they constitute a threat to the national life. Family life may also collapse and the increase of mixed breed bastards may some day challenge the supremacy of the white man.
