A very interesting two volume set on the history of the supernatural. King was an American anthropologist who suggested that religion and magic evolved as an attempt by primitive man to bring some control over the unfathomable natural forces that seemingly control life. The book discusses the concepts of the supernatural and soul, of spirits and ghosts, that can arise through dreams and hallucinations, and from them comes the idea of Gods. Featuring chapters on The Evolution of Charms and Spells, The Origin of Ghosts, The Evolution of Ancestral Worship, and Animal Concepts of the Supernatural.
