“Among our neighbors of Central and Southern America, we see the Caucasian mingled with the Indian and the African. They have the forms of free government, because they have copied them. To its benefits they have not attained, because that standard of civilization is above their race. Revolution succeeds Revolution, and the country mourns that some petty chief may triumph, and through a sixty days' government ape the rulers of the earth.”

Context: It is in order that each of you may have through this free government which we have enjoyed, an open field and a fair chance for your industry, enterprise and intelligence; that you may all have equal privileges in the race of life, with all its desirable human aspirations. It is for this the struggle should be maintained, that we may not lose our birthright — not only for one, but for two or three years. The nation is worth fighting for, to secure such an inestimable jewel.

The Cornerstone Speech (1861)
Context: But not to be tedious in enumerating the numerous changes for the better, allow me to allude to one other though last, not least. The new constitution has put at rest, forever, all the agitating questions relating to our peculiar institution African slavery as it exists amongst us; the proper status of the negro in our form of civilization. This was the immediate cause of the late rupture and present revolution. Jefferson in his forecast, had anticipated this, as the 'rock upon which the old Union would split'. He was right. What was conjecture with him, is now a realized fact. But whether he fully comprehended the great truth upon which that rock stood and stands, may be doubted. The prevailing ideas entertained by him and most of the leading statesmen at the time of the formation of the old constitution, were that the enslavement of the African was in violation of the laws of nature; that it was wrong in principle, socially, morally, and politically. It was an evil they knew not well how to deal with, but the general opinion of the men of that day was that, somehow or other in the order of Providence, the institution would be evanescent and pass away.

As quoted in Kenya National Assembly Official Record (Hansard) Jul 23 - Nov 29, 1963. p. 1223.
Context: Unless we have a Government with capable officers to run it, then our Government will fall tomorrow. I want the people to understand this: that we have this policy of Africanization, as we have during the time we have taken over the Government; people are being trained for various posts, and when they are ready we shall give them responsibility, but we cannot take people just because they are black and say "All right, you run this, you run that." We have to learn by experience, and this is the policy of my Government. In our Kanu manifiesto, we state clearly that we are not going to discriminate because of race, colour or religion. We are going to treat Kenyans on an equal footing and the law of Kenya is going to apply to Europeans, Asians and Africans, those who are citizens of this country. They are going to be treated alike. We cannot have our cake and eat it. We have started our policy and we are going to follow it.
