Things do not (always) have the same meaning everywhere; when we insist that only "our" meaning is the "true" meaning, we silence other people's meanings. What passes as universality is someone else's culture and just enough power to spread it, even force it, upon others. The things that words denote never start as universal or available everywhere, their meanings already stabilized; they originate from a particular place, community, society, culture, and nation and then, through travel or mobility, become universal, global. The issue to address is why specific words get to be used when, how, and where they are.Today, our definitions of science, technology, and innovation (STI) originate from countries and cultures that have acquired their dominance of others through global empires-military, capital, and media-and are able to purvey to or even impose upon those without such power their definitions. This asymmetry of definitional power was never lost to commentators in the West, like Edward H. Carr, who emphasized that people care to know and enquire into an event if it is worth knowing. If it is not, they forget about it (Carr 1961, 11). In that same discussion, Carr concluded: "When we take up a work of history, our first concern should be not with the facts which it contains but with the historian who wrote it" (22).Similarly, in this volume the question is neither what the concepts of science, technology, and innovation mean universally or all the time nor what Western STI transferred or diffused to Africa means to Africans. Instead, we seek to put the concepts of STI up for grabs, on sale epistemologically, so that there is no universal or spatiotemporally transcendent definition. We seek to explore what the technological, the scientific, and the innovative might mean from Africa in lieu of outside introductions or influences. It is important to do this now because we feel that the importation and consumption of rigid Western meanings of STI are a serious and dangerous threat to a self-determined African path to the future.The concepts of STI matter at this specific historical moment in Africa because there seems to be a feeling that Africa's time has come. This Africa is rising narrative is all over the World Wide Web, often under the name Afrofuturism. As if to capture its spirit, in 2014 the African Union issued a Science, Technology, and Innovation Strategy for Africa (STISA 2024), with science, technology, and innovation as the centerpiece of modernity. In the document, the
