This book dabbles in many fields, including not only African religion and philosophy but also history, anthropology, and general African studies. Mbiti tells an African story from an African point of view, which shows depth in what they actually believed.
This book is told from an African's point of view, but it also incorporates Christianity. Indeed, Mbiti shows the problems that Africans face in the western world. This book also explores many different "universal" concepts, such as time, good vs evil, and God.
