"You and I are different races. We have between us a broader difference than exists between almost any other races. Whether it be 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 amongst 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.
"Your race are suffering, in my judgment, the greatest wrong inflicted on any people. But even when you cease to be slaves, you are yet far removed from being placed on equality with the White race. On this broad continent, not a single man of your race is made the equal of a single man of ours. Go where you are treated the best, and the ban is still upon you. I cannot alter it if I would.
"I need not recount to you the effects upon White men, growing out of the institution of slavery. See our present condition - the country engaged in war! - our White men cutting one another's throats, none knowing how far it will extend; and then consider what we know to be the truth. But for your race among us there would be no war, although many men engaged on either side do not care for you one way or the other. It is better for us both, therefore, to be separated."(The Collected Works of Abraham Lincoln, edited by Roy P. Baler, Rutgers University Press, 1953, Vol. V, pages 371-375.)
