Abraham Lincoln and integration

Having all been seated, the President, after a few preliminary observations, informed them that a sum of money had been appropriated by Congress, and placed at his disposition for the purpose of aiding the colonization in some country of the people, or a portion of them, of African descent, thereby making it his duty, as it had for a long time been his inclination, to favor that cause; and why, he asked, should the people of your race be colonized, and where? Why should they leave this country? 

This is, perhaps, the first question for proper consideration. You and we are different races. We have between us a broader difference than exists between almost any other two races. Whether it is right or wrong I need not discuss, but this physical difference is a great disadvantage to us both, as I think your race suffer very greatly, many of them by living among us, while ours suffer from your presence. In a word we suffer on each side. If this is admitted, it affords a reason at least why we should be separated.

I can hardly believe that the South and North can live in peace, unless we can get rid of the negroes ... I believe that it would be better to export them all to some fertile country with a good climate, which they could have to themselves.

I have no purpose to introduce political and social equality between the white and the black races. There is a 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.

I will say then, that I am not nor ever have been in favor of making voters of the negroes, or jurors, or qualifying them to hold office, of having them to marry with white people. I will say in addition, that there is a physical difference between the white and black races, which I suppose, will forever forbid the two races living together upon terms of social and political equality, and inasmuch, as they cannot so live, that while they do remain together, there must be the position of superior and inferior, that I as much as any other man am in favor of the superior position being assigned to the white man.
