At the Back of the Black Man's Mind by R. E. Dennett is a seminal ethnographic work that explores the religious beliefs, customs, and spiritual worldview of West African peoples, particularly those in the Congo region. Drawing from firsthand observation and native accounts, Dennett examines the deep-rooted traditions, folklore, ancestor worship, and mythologies that shaped the moral and metaphysical understanding of African societies. Though written in the early 20th century and reflective of its colonial-era perspective, the book remains a valuable resource for understanding indigenous African cosmologies and cultural expressions. It offers readers insight into the complexity, symbolism, and rich oral traditions that lie "at the back of the Black man's mind," while also inviting critical reflection on the lenses through which such cultures have been studied and represented.
