From the beginning, Europe assumed the power to make decisions within the international trading system. An excellent illustration of that is the fact that the so-called international law which governed the conduct of nations on the high seas was nothing else but European law. Africans did not participate in its making, and in many instances, African people were simply the victims, for the law recognized them only as transportable merchandise. If the African slave was thrown overboard at sea, the only legal problem that arose was whether or not the slave ship could claim compensation from the insurers! Above all, European decision-making power was exercised in selecting what Africa should export – in accordance with European needs. Pg. 77

The truth is that any figure of Africans imported into the Americas which is narrowly based on the surviving records is bound to be low, because there were so many people at the time who had a vested interest in smuggling slaves (and withholding data. Nevertheless, if the low figure of ten million was accepted as basis for evaluating the impact of slaving on Africa as a whole, the conclusions that could legitimately be drawn would confound those who attempt to make light of the experience of the rape of Africans from 1445 to 1870. Pg. 96

On any basic figure of the Africans landed alive in the Americas, one would have to make several extensions- starting with a calculation to cover mortality in transshipment. The Atlantic crossing, or “Middle Passage,” as it was called by European slavers, was notorious for the number of deaths incurred, averaging in the vicinity of 15-20 per cent. There were also numerous deaths in Africa between time of capture and time of embarkation, especially in cases where captives had to travel hundreds of miles to the coast. Most important of all (given that warfare was the principal means of obtaining captives) it is necessary to make some estimate of the number of people killed and injured so as to extract the millions who were taken alive and sound. The resultant figure would be many times the millions landed alive outside of Africa, and it is that figure which represents the number of Africans directly removed from the population and labor force of Africa because of the establishment of slave production by Europeans.

Development means a capacity for self-sustaining growth. It means that an economy must register advances which in turn will promote further progress. The loss of industry and skill in Africa was extremely small, if we measure it from the viewpoint of modern scientific achievements or even by the standards of England in the late eighteenth century. However, it must be borne in mind that to be held back at one stage means that it is impossible to go on to a further stage. When a person is forced to leave school after only two years of primary school education, it is no reflection on him that he is academically and intellectually less developed than someone who had the opportunity to be schooled right through to university level. What Africa experienced in the early centuries of trade was precisely a loss of development opportunity, and this is of greatest importance. Pg. 105
