James George Frazer attempted to define the shared elements of religious belief and scientific thought, discussing fertility rites, human sacrifice, the dying god, the scapegoat, and many other symbols and practices whose influences had extended into 20th-century culture. His thesis is that old religions were fertility cults that revolved around the worship and periodic sacrifice of a sacred king. Frazer proposed that mankind progresses from magic through religious belief to scientific thought. (Excerpt from Wikipedia)
Sir James George Frazer; (1 January 1854 – 7 May 1941) was a Scottish social anthropologist and folklorist[3] influential in the early stages of the modern studies of mythology and comparative religion.[4] He is often considered one of the founding fathers of modern anthropology. His most famous work, The Golden Bough (1890), documents and details the similarities among magical and religious beliefs around the globe. Frazer posited that human belief progressed through three stages: primitive magic, replaced by religion, in turn replaced by science. (Wikipedia)
