future"). Nevertheless, it is said, "God will outlive eternity." History is seen as vitally important ("One ignorant of his origin is nonhuman"), and historians (known as "sons of the soil") are highly revered ("The son of the soil has the python's keen eyes"). However, these arguments must be taken with a grain of cultural relativism, as the span of culture in Africa is incredibly vast, with patriarchies, matriarchies, monotheists and traditional religionists among the population, and as such the attitudes of groups of the Niger Delta cannot be applied to the whole of Africa. Another more controversial application of this approach is embodied in the concept of Negritude. Leopold Senghor, a proponent of Negritude, argued that the distinctly African approach to reality is based on emotion rather than logic, works itself out in participation rather than analysis, and manifests itself through the arts rather than the sciences. Cheikh Anta Diop and Mubabinge Bilolo, on the other hand, while agreeing that African culture is unique, challenged the view of Africans as essentially emotional and artistic, arguing that Egypt was an African culture whose achievements in science, mathematics, architecture, and philosophy were pre-eminent. This philosophy may also be maligned as overly reductionist due to the obvious scientific and scholarly triumphs of not only ancient Egypt, but also Nubia, Meroe, as well as the great library of Timbuktu, the extensive trade networks and kingdoms of North Africa, West Africa, Central Africa, the Horn of Africa and Great Zimbabwe and the other major empires of Southern, Southeast and Central Africa. Critics of this approach argue that the actual philosophical work in producing a coherent philosophical position is being done by the academic philosopher (such as Alagoa), and that the sayings of the same culture can be selected from and organised in many different ways in order to produce very different, often contradictory systems of thought. Philosophical sagacity is a sort of individualist version of ethnophilosophy, in which one records the beliefs of certain special members of a community. The premise here is that, although most societies demand some degree of conformity of belief and behaviour from their members, a certain few of those members reach a particularly high level of knowledge and understanding of their cultures' worldviews; such people are sages. In some cases, the sage goes beyond mere knowledge and understanding to reflection and questioning—these become the targets of philosophical sagacity. Critics of
