My own justification, the proof that my treatment of the Africans is correct, I think I will provide later; I will then wait calmly to see whom future developments will prove right. I did not go to Africa to make the natives happy. I had no internal or external reason to do so—just as I have not found that the Africans feel a special need to go to Europe to make us happy. Rather, I have pursued colonial policy in order to serve my own countrymen and the power of the German Empire. But I have always believed that this indirectly benefits the interests of the Negro world as well; and all the more so the more resolutely it is transferred to the new economic order, whereby, of course, violent measures cannot always be avoided. I am convinced that in every colonial policy everything depends on the economic advantages that the colonizing people gain from it, and such advantages can only be utilized if the exploitation and development of the new countries is carried out according to the principles of common sense. As far as I know world history, no great successes have ever been achieved with academic theories and utopias.
