Religion is an important aspect of human life for most people in the world. It can provide meaning and purpose, give a sense of belonging to a group, encourage social change, help to cope with death and loss, and offer comfort in the face of suffering and difficulty. However, religion is also a source of conflict and violence in many societies. The concept of religion is complex and difficult to define. Some scholars see it as a genus of social phenomena that has distinguishing characteristics, such as intensity and comprehensiveness, that separate it from other forms of valuation in human life. Others define religion as a particular set of beliefs and practices that are considered sacred by its adherents. This definition includes elements such as veneration of gods, a belief in the afterlife, and an emphasis on morality.
Various approaches to the study of religion have evolved over time, influenced by such developments as the rise of social sciences, including history, archaeology, and anthropology, as well as the growth of scientific knowledge about different cultures throughout the world. Emile Durkheim, for example, saw religion as a form of solidarity that creates a common ground for people to unite and share their concerns. This view continues to shape sociological thinking on the nature of religion.
Another approach to the study of religion focuses on the ways that religious beliefs and practices are interpreted by individuals. This is known as the symbolic interactionist approach to religion. It argues that religious beliefs and practices are not necessarily true or false, but they become so for their believers because of the special meaning they hold for them. The works of Friedrich Schelling, Ludwig Feuerbach, and Sigmund Freud are examples of this perspective.
A third approach to the study of religion focuses on its functions in society. The work of Paul Tillich, for example, relies on a functional analysis that looks at the way in which a religion organizes a person’s values rather than examining whether or not it involves belief in unusual realities.
In a modern context, the concept of religion is most often used as a taxon for sets of social behaviors, a category that has paradigmatic examples in the so-called world religions such as Judaism, Christianity, Islam, Hinduism, Buddhism, Confucianism, and Daoism. The world’s 6.5 billion people practice one of the religions, and many more participate in non-religious rituals that serve similar functions, such as music, art, architecture, and other aspects of culture. Despite its inability to be defined with certainty, religion remains an important and influential aspect of human lives. For this reason it deserves careful attention from professionals, policymakers, and the media. If nothing else, a greater understanding of the role of religion in the world can help reduce the conflict, hostility, and violence that is spawned by it.
