The Portuguese stand out because they boasted the most and did the least. Portugal boasted that Angola, Guinea, and Mozambique have been their posses… - Walter Rodney

More far-reaching than just trade is the actual ownership of the means of production in one country by the citizens of another. When citizens of Europe own the land and the mines of Africa, this is the most direct way of sucking the African continent. Under colonialism the ownership was complete and backed by military domination. Today, in many African countries the foreign ownership is still present, although the armies and flags of foreign powers have been removed. So long as foreigners own land, mines, factories, banks, insurance companies, means of transportation, newspapers, power stations, then for so long will the wealth of Africa flow outwards into the hands of those elements. In other words, in the absence of direct political control, foreign investment insures that the natural resources and the labor of Africa produce economic value which is lost to the continent.

So long as there is political power, so long as a people can be mobilized to use weapons, and so long as a society has the opportunity to define its own ideology and culture, then the people of that society have some control over their own destinies, in spite of constraints such as those imposed as the African continent slipped into orbit as a satellite of capitalist Europe. After all, although historical development is inseparable from material conditions and the state of technology, it is also partially controlled by a people’s consciousness at various stages.

Science and technology derive from the effort to understand and control the natural environment. Familiarity with the history of science is essential to an awareness of the development of society.
