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)
