Tylor also theorized about the origins of religious beliefs in human beings, proposing a theory of animism as the earliest stage, and noting that "religion" has many components, of which he believed the most important to be belief in supernatural beings (as opposed to moral systems, cosmology, etc.). Frazer, a Scottish scholar with a broad knowledge of Classics, also concerned himself with religion, myth, and magic. His comparative studies, most influentially in the numerous editions of "The Golden Bough", analyzed similarities in religious belief and symbolism globally. Neither Tylor nor Frazer, however, was particularly interested in fieldwork, nor were they interested in examining how the cultural elements and institutions fit together. The Golden Bough was abridged drastically in subsequent editions after his first.
