Religion is a complex topic that cannot be defined easily. Some people claim that religion is only a system of beliefs or faith, but others suggest that it has more to do with cultural attitudes, ethics, and morality than with a particular deity or cosmology. Still others argue that a definition of religion must take into account the impact of various social forces, such as morality and authority.
Sociologists use several tools to study the phenomenon of religion, including survey research, interviewing, historical analysis, and observation. They may also apply a variety of social scientific methods, such as comparative and contrast analysis, cause-effect modeling, and interactionist perspectives. However, sociologists generally agree that the most important aspect of religion is how it affects society.
Throughout history, religion has been a significant part of many cultures. People have used religion to give meaning and purpose to their lives, strengthen family ties, foster social cohesion and stability, control behavior, promote health and wellbeing, and inspire people to work for positive social change.
Some people define religion as a belief in spiritual beings that are not human and that exist outside the material universe. Others say that religion is the set of practices that people use to make sense of the world and their place in it. Still others insist that a definition of religion must include the observance of rituals and ceremonies.
Trying to understand how and why some activities or beliefs are considered religious raises profound questions about the nature of reality and the human condition. Several philosophical issues arise for this contested concept that are probably similar to those that would be raised by other abstract concepts, such as literature or democracy, when studied in the same way.
Substantive definitions of religion are often thought to resist a certain ideological image of humans as passive, indoctrinated, and unable to make their own decisions. Functional definitions, on the other hand, tend to emphasize a role for religion in promoting or reinforcing certain aspects of human society.
The debate over the appropriate approach to the study of religion has centered on whether to define it substantively or functionally and, if substantively, how to draw the line between something that is considered religious and something that is not. Some scholars have favored the former, holding that any social phenomenon can be accurately described by a word or phrase that shares a defining property with that phenomenon. Others have favored the latter, adopting a prototype theory of concepts. These approaches are not mutually exclusive and can be combined to create a hybrid of the two. Ultimately, the debate over how to study religion will help to shape the future of the discipline. A key question will be the extent to which social scientists will adopt a mixture of these approaches. This will be determined, in part, by the extent to which political and economic factors in a country encourage or discourage the practice of religion.
