“My strongest conviction as to the future of the negro therefore is, that he will not be expatriated nor annihilated, nor will he forever remain a separate and distinct race from the people around him, but that he will be absorbed, assimilated, and will only appear finally, as the Phoenicians now appear on the shores of the Shannon, in the features of a blended race. I cannot give at length my reasons for this conclusion, and perhaps the reader may think that the wish is father to the thought, and may in his wrath denounce my conclusion as utterly impossible. To such I would say, tarry a little, and look at the facts.”

This is from a fictional speech by Lincoln which occurs in The Clansman : An Historical Romance of the Ku Klux Klan (1905) by Thomas Dixon, Jr.. On some sites this has been declared to be something Lincoln said "soon after signing" the Emancipation Proclamation, but without any date or other indications of to whom it was stated, and there are no actual historical records of Lincoln ever saying this.

Fourth Lincoln-Douglas Debate (Charleston, 18 September 1858)
1850s, Lincoln–Douglas debates (1858)
Context: While I was at the hotel to-day, an elderly gentleman called upon me to know whether I was really in favor of producing perfect equality between the negroes and white people. While I had not proposed to myself on this occasion to say much on that subject, yet as the question was asked me, I thought I would occupy perhaps five minutes in saying something in regard to it. I will say then that I am not, nor ever have been, in favor of bringing about in any way the social and political equality of the white and black races, that I am not, nor ever have been, in favor of making voters or jurors of negroes, nor of qualifying them to hold office, nor to intermarry with white people; and I will say in addition to this that there is a physical difference between the white and black races which I believe will forever forbid the two races living together on terms of social and political equality. And inasmuch as they cannot so live, while they do remain together there must be the position of superior and inferior, and I as much as any other man am in favor of having the superior position assigned to the white race. I say upon this occasion I do not perceive that because the white man is to have the superior position the negro should be denied every thing. I do not understand that because I do not want a negro woman for a slave I must necessarily want her for a wife. My understanding is that I can just let her alone. I am now in my fiftieth year, and I certainly never had a black woman for either a slave or a wife. So it seems to me quite possible for us to get along without making either slaves or wives of negroes. I will add to this that I have never seen, to my knowledge, a man, woman, or child who was in favor of producing a perfect equality, social and political, between negroes and white men... I have never had the least apprehension that I or my friends would marry negroes if there was no law to keep them from it, but as Judge Douglas and his friends seem to be in great apprehension that they might, if there were no law to keep them from it, I give him the most solemn pledge that I will to the very last stand by the law of this State, which forbids the marrying of white people with negroes.

The Decline of the West (1918, 1923)

Celui qui ignore à quel point la fortune variable et la nécessité tiennent toute âme humaine sous leur dépendance ne peut pas regarder comme des semblables ni aimer comme soi-même ceux que le hasard a séparés de lui par un abîme. La diversité des contraintes qui pèsent sur les hommes fait naître l'illusion qu'il y a parmi eux des espèces distinctes qui ne peuvent communiquer.

Referring to Mr. Burns. Compare to Heart of Darkness' manager: "He was becoming confidential now, but I fancy my unresponsive attitude must have exasperated him at last, for he judged it necessary to inform me he feared neither God nor devil, let alone any mere man. I said I could see that very well..."
