Ethnophilosophy’s damning flaw is its interdisciplinary method, which makes it insufficiently technical for philosophy

Evidence

The most pertinent problem that rears its head with Tempels’s relationship to ethnophilosophy has to do with the accusation that ethnophilosophy is not sufficiently technical to count as a philosophical discourse. This lack of technical nuance may be traced to Tempels’s desire to understand the Muntu through a confluence of disciplines, such as anthropology and psychology. — Frans Dokman, Beyond Bantu Philosophy_…, 440
