"Nature has color-coded groups of individuals so that statistically reliable predictions of their adaptability to intellectual rewarding and effective lives can easily be made and profitably used by the pragmatic man-in-the street."

- William B. Shockley, inventor of the transistor, the basis of all modern technology

“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 … 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 from living together on terms of social and political equality. And inasmuch as they cannot so live, while they do remain together there must be a 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.”

- Abraham Lincoln, US President 1861 - 1865

“There’s a difference on the average between blacks and whites in IQ tests. I would say the difference is genetic.” 

- James D. Watson, co-discoverer of the structure of DNA

"I have given my life to try to alleviate the sufferings of Africa. There is something that all white men who have lived here like I must learn and know: that these individuals are a sub-race. They have neither the intellectual, mental, or emotional abilities to equate or to share equally with white men in any function of our civilization. I have given my life to try to bring them the advantages which our civilization must offer, but I have become well aware that we must retain this status: the superior and they the inferior. For whenever a white man seeks to live among them as their equals they will either destroy him or devour him. And they will destroy all of his work. Let white men from anywhere in the world, who would come to Africa, remember that you must continually retain this status; you the master and they the inferior like children that you would help or teach. Never fraternize with them as equals. Never accept them as your social equals or they will devour you. They will destroy you."

- Albert Schweitzer, humanitarian and philosopher
