Ethnophilosophy is the study of indigenous philosophical systems. The implicit concept is that a specific culture can have a philosophy that is not applicable and accessible to all peoples and cultures in the world; however, this concept is disputed by traditional philosophers.  An example of ethnophilosophy is African philosophy.
