In How Native Think, philosopher-sociologist Lucien Levy-Bruhi explores the nature of primitive mental-the tribal concepts, the psychic responses, the language, myth and ritual of non-literate societies. From his studies, Levy-Bruhl notes the prevalence of mysticism in the early stages of human thinking, and demonstrates how this mystical thought is a distinct kind of metal process, rather than a result of faulty perception, or a product of irrational thinking.
