Because it is such an important social institution, religion has long been a key sociological topic. Émile Durkheim (1915/1947) [1] observed long ago that every society has beliefs about things that are supernatural and awe-inspiring and beliefs about things that are more practical and down-to-earth. He called the former beliefs sacred beliefs and the latter beliefs profane beliefs. Religious beliefs and practices involve the sacred: they involve things our senses cannot readily observe, and they involve things that inspire in us awe, reverence, and even fear.
