The book "Elementary Forms of Religious Life" by Emile Durkheim is a classic study in the field of sociology of religion. In his work, Durkheim studies the religious ideas and practices of primitive societies, considering religion as a key element of social life. The leading idea of the book is that religion is not a simple illusion or fiction, but has deep roots in social structures and human psychology. Durkheim analyzes religious rituals, symbols, and creeds, arguing that they reflect society's basic needs for unity, meaning, and interaction. This book is an important contribution to understanding the nature of religion and society and is designed to expand our understanding of how religious beliefs shape our worldviews and actions.
