The Elementary Forms of Religious Life (French: "Les formes élémentaires de la vie religieuse" ), published by French sociologist Émile Durkheim in 1912, is a book that analyzes religion as a social phenomenon.
 Durkheim attributes the development of religion to the emotional security attained through communal living.
 His study of totemic societies in Australia led to a conclusion that the animal or plant that each clan worshipped as a sacred power was in fact that society itself.
 Halfway through the text, Durkheim inquisites that, "So if [the totem animal] is at once the symbol of the god and of the society, is that not because the god and the society are only one."
