We were told that violence in itself is evil, and that, whatever the cause, it is unjustified morally. By what standard of morality can the violence … - Walter Rodney

It can be noted that Shaka was challenged to create the heavy stabbing when he realized that the throwing spear broke when used as a stabbing weapon. More important still, what Shaka came up with depended upon the collective effort of the Ama-Zulu. Shaka could ask that a better assegai be forged, because the Ama-Ngoni had been working iron for a long time, and specialist black-smiths had arisen within certain clans. It was a tribute to the organizational and agricultural capacity of the society as a whole that it could feed and maintain a standing army of thirty thousand men, re-equip them with iron weapons, and issue each soldier with the full-length Zulu shield made from cattle hide. Because the scientific basis and experimental preconditions were lacking in Zulu society, Shaka could not have devised a firearm—no matter how much genius he possessed. But, he could get his people to forge better weapons, as explained above; and he found them receptive to better selective breeding practices when he set up special royal herds, because the people already had a vast fund of empirical knowledge about cattle and a love of the cattle-herding profession.

It is only the organization and resoluteness of the working class which protects it from the natural tendency of the capitalist to exploit to the utmost.

One major problem in Africa from a capitalist viewpoint was how to induce Africans to become laborers or cash-crop farmers. In some areas, such as West Africa, Africans had become so attached to European manufactures during the early period of trade that, on their own initiative, they were prepared to go to great lengths to participate in the colonial money economy. But that was not the universal response. In many instances, Africans did not consider the monetary incentives great enough to justify changing their way of life so as to become laborer or cash-crop farmers. In such cases, the colonial state intervened to use law, taxation, and outright force to make Africans pursue a line favorable to capitalist profits. When colonial governments seized African lands, they achieved two things simultaneously. They satisfied their own citizens (who wanted mining concessions or farming land) and they created the conditions whereby landless Africans had to work not just to pay taxes but also to survive. In settler areas such as Kenya and Rhodesia the colonial government also prevented Africans from growing cash crops so that their labor would be available directly for the whites. One of the Kenya white settlers, Colonel Grogan, put it bluntly when he said of the Kikuyu: “We have stolen his land. Now we must steal his limbs. Compulsory labor is the corollary of our occupation of the country.”
