Habitat, Economy and Society in the Central Africa Rain Forest [PDF ebook] 

Over 50 years ago, the renowned anthropologist Daryll Forde strongly advocated comparative anthropological studies. Professor Vansina argues that 50 years later, Forde’s criticisms still apply despite both Forde’s considerable intellectual legacy and an exponential increase in available information. Using the example of Central African peoples, Professor Vansina challenges the current scholarship of sociologists and anthropologists, and makes a compelling case for broad, historical, comparative studies.
