"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."

- Abe Lincoln
