The Secret of the Totem is one of Andrew Lang's most important works on anthropology and comparative religion. First published in 1905 the book investigates the origins meanings and evolution of totemism—the ancient system in which clans or tribes identify themselves with particular animals plants or natural objects. Lang critically examines the leading anthropological theories of his day including those of J. G. Frazer Émile Durkheim and other prominent scholars while presenting his own interpretation of how totemic societies developed. Drawing extensively from the customs and social structures of Australian Aboriginal communities and other Indigenous cultures Lang explores subjects such as kinship exogamy clan organization marriage rules ancestor beliefs and the symbolic role of totems in early human societies. Rather than merely describing customs he evaluates competing theories through historical and comparative analysis. A foundational work in the history of anthropology The Secret of the Totem remains valuable for students and researchers interested in cultural anthropology sociology comparative religion folklore mythology and the intellectual development of early social science.
