Religion is a broad category of cultural systems of beliefs, practices and ethics. Belief in a deity or divine beings is at the heart of many religions, and some of them include doctrines and rituals around prayer, devotion and worship. For some people, a religious system provides a sense of belonging to a community, and many religions encourage moral conduct and social action. For others, the practice of religion serves as a comfort in hard times or a source of spiritual guidance.
The word “religion” derives from the Latin “religio,” meaning “to bind.” The concept of religion evolved as a way to describe social groups that bound together through a common identity, purpose or worldview. In the modern world, religions often have a smaller role to play than they did in earlier eras. Only one member of the United States Congress, for example, claims any religious affiliation and fewer people in general claim any particular religion. However, the human need to belong is strong, and research has shown that social connections can help individuals live longer and happier lives.
Scholars have debated the concept of religion for centuries. For instance, Edward Burnett Tylor used the term to describe the belief in spiritual beings. Later, Emile Durkheim focused on how religion creates a sense of community and how it influences people’s values and life choices. In addition, scholars like Paul Tillich emphasized the function of religion as an overall orientation to life and defined it as whatever dominant concern organizes a person’s values regardless of whether or not those concerns involve belief in unusual realities.
More recently, anthropologists like Clifford Geertz and Talal Asad have questioned the assumptions baked into the concept of religion. They have called for scholars to shift their attention from hidden mental states to the visible institutional structures that inculcate those states. They argue that a Foucauldian approach to understanding religion is needed, and they emphasize the role of power in shaping the nature of religiosity.
Despite such critical work, scholars continue to use the term “religion” in their research. But they also recognize that the semantic range of what is called a religion has shifted over time and that the concept is problematic. This is because a shift in what counts as a religion changes the meaning of the word, and it also reveals that there are political underpinnings to how the concept is used.
A number of scholars have argued that to define a religion by its beliefs or even its activities is a form of Protestant essentialism. Others, such as Talal Asad, have applied Michel Foucault’s genealogical approach to studying cultures to the study of religion. They have argued that a social kind called “religion” exists in the world and has its own existence independent of how it is categorized, and they have criticized the way that modern anthropology has treated concepts like religion as tools invented for the purposes of European colonialism.
