Interview with Louis Theroux on Weird Weekends (2 June 1999)
“After half a century of co-operation – difficult, at times very difficult – a stage has been reached when both groups [i. e. Afrikaans and English-speaking whites] as never before are faced with a challenge to bury the past, to let it become the combined history of a unified volk/people. Today we are faced with threats for the future of our civilization, for our prosperity, for the contribution of the white man of Africa to the struggle of the white man of Europe and America to retain his hegemony in the world. Also to make Christianity victorious, sacrifices must be made, and nowhere is Christianity more threatened than in Africa. Sacrifices of sentiment is expected of everybody. There must not only be a union of provinces in South Africa. There must also be a union of hearts.”
Verwoerd in 1963, as quoted and translated by J. J. Venter in H.F. Verwoerd: Foundational aspects of his thought, Koers 64(4) 1999: 415–442

Preface
The Mis-Education of the Negro (1933)
Context: The educational system as it has developed both in Europe and America an antiquated process which does not hit the mark even in the case of the needs of the white man himself. If the white man wants to hold on to it, let him do so; but the Negro, so far as he is able, should develop and carry out a program of his own.
The so-called modern education, with all its defects, however, does others so much more good than it does the Negro, because it has been worked out in conformity to the needs of those who have enslaved and oppressed weaker peoples. For example, the philosophy and ethics resulting from our educational system have justified slavery, peonage, segregation, and lynching. The oppressor has the right to exploit, to handicap, and to kill the oppressed. Negroes daily educated in the tenets of such a religion of the strong have accepted the status of the weak as divinely ordained, and during the last three generations of their nominal freedom they have done practically nothing to change it.

This has usually been presented as something "said shortly before his death" without any definite source, but appears to be entirely spurious. The "FAQ about the life and thoughts of Albert Schweitzer" http://www.schweitzer.org/faq?lang=en#rasist asserts "This quote is utterly false and is an outrageously inaccurate picture of Dr. Schweitzer’s view of Africans. Dr. Schweitzer never said or wrote anything remotely like this. It does NOT appear in the book African Notebook." This refers to some citations of it being from Afrikanische Geschichten (1938), which was translated as From My African Notebook (1939) by Mrs. C. E. B Russell

1870s, Oratory in Memory of Abraham Lincoln (1876)
Context: Few facts could better illustrate the vast and wonderful change which has taken place in our condition as a people than the fact of our assembling here for the purpose we have today. Harmless, beautiful, proper, and praiseworthy as this demonstration is, I cannot forget that no such demonstration would have been tolerated here twenty years ago. The spirit of slavery and barbarism, which still lingers to blight and destroy in some dark and distant parts of our country, would have made our assembling here the signal and excuse for opening upon us all the flood-gates of wrath and violence. That we are here in peace today is a compliment and a credit to American civilization, and a prophecy of still greater national enlightenment and progress in the future. I refer to the past not in malice, for this is no day for malice, but simply to place more distinctly in front the gratifying and glorious change which has come both to our white fellow citizens and ourselves, and to congratulate all upon the contrast between now and then, the new dispensation of freedom with its thousand blessings to both races, and the old dispensation of slavery with its ten thousand evils to both races, white and black. In view, then, of the past, the present, and the future, with the long and dark history of our bondage behind us, and with liberty, progress, and enlightenment before us, I again congratulate you upon this auspicious day and hour.
