Oruka classified African philosophy into four distinct trends

Evidence

One of the major challenges Oruka undertook was to structure the issues of the discourse on African philosophy in an orderly manner. He contributes to this debate by identifying four trends in current African philosophy (Oruka, 1990): ethnophilosophy, professional philosophy, nationalist–ideological philosophy, and philosophic sagacity. — Frans Dokman, Beyond Bantu Philosophy_…, 575
