“Iwill say then that I am not, nor ever have been in favor of bringingabout in anyway the social and political equality of the white andblack races – that I am not nor ever have been in favor of makingvoters or jurors of Negroes, nor of qualifying them to hold office, norto intermarry with white people; and I will say in addition to thisthat there is a physical difference between the white and black raceswhich I believe will forever forbid the two races living together onterms of social and political equality.” — Abraham Lincoln, Source: September 18, 1858 – Fourth Debate with Stephen A. Douglas at Charleston, Illinois
