Abstract
The entirety of African cosmology among all other things embraces their whole fields of sciences, metaphysics and arts but the point of concentration for analysis and clarification is on their sciences (Scientific knowledge). Going by the history of the western science, it appears that the tendency of nationalizing science could be justifiable depending on how one sees it. Science could be taken as objective and universal with respect to the goals it intends to achieve. But the approach could vary from one culture to another basically because it is a methodology. This implies that the growth of scientific knowledge is not limited only to the western world but inherent to every set of people irrespective of the color or race. This paper, however, is of the view that there are sciences of which African scientific knowledge represents a phase in the progress of science; and that the western science and that of the African science are on equal race of achieving the truth. We also assert that both scientific knowledge of African system and Karl Popper’s philosophy of science operate on the same epistemological foundation. Thus, we shall use the modern terms and ideas of Karl Popper to argue that African methodology of attaining the truth is a science in its own right and that it has also helped them to advance in their knowledge.
