A Category Almost Every Culture Independently Reached

Belief in the persisting, sometimes visible or audible spirit of the dead is close to a human universal, appearing in societies with no historical contact with one another and taking forms specific enough to their own culture that the many named entries elsewhere in this atlas, from the Chinese gui to the Norse draugr to the Jamaican duppy, are better understood as regional elaborations of this same underlying idea than as unrelated inventions.

Edward Burnett Tylor's nineteenth-century anthropological work on animism, one of the foundational texts of comparative religious studies, proposed that belief in souls and ghosts arose from early human attempts to explain dreams, shadows, reflections and the visible difference between a living and a dead body, a theory that remains influential, if contested and refined, in the modern anthropology of religion. What varies enormously across cultures is not whether ghosts exist as a concept but what a ghost is for: a moral warning, an unresolved family obligation, a source of forbidden knowledge, or simply an acknowledgement that death does not always fully sever a person's presence from the community and places they belonged to in life.
