"Totem and Taboo: Resemblances between the psychic lives of savages and..." by Sigmund Freud is a collection of four essays published in 1913. Freud applies psychoanalytic concepts to anthropology, archaeology, and religion, drawing controversial parallels between primitive societies and neurotic patients. Through examining incest taboos, totemism, animism, and the origins of social organization, he explores ambivalence, projection, and the "omnipotence of thoughts." The work proposes a provocative theory about the primal origins of human society and religious guilt, though its conclusions remain hotly debated among anthropologists.
