Suppressing either African or Western knowledge silences part of shared history.

Evidence

When indigenous knowledge is ignored or silenced in scholarship, the African voice is either suppressed or sidelined. Likewise, ignoring Western conceptualizations silences a Western part of our history, further depriving the West from benefitting from the truth that only African philosophers can tell about their African ontology. In reality, research by many African scholars has proved that Western theories are relevant to African realities and vice versa. As such, African knowledge has much to enrich existing Western knowledge and methodologies. — Frans Dokman, Beyond Bantu Philosophy_…, 905
