Religion is human beings’ relation to that which they regard as holy, sacred, absolute, spiritual, divine, or worthy of especial reverence. Often, these concerns are focused on a god or gods (monotheism) or may be broader in scope, involving humankind and the natural world (hell or heaven). It is also commonly viewed as the way people deal with ultimate questions about life and death.
The concept of religion has long evoked intense feelings among those who discuss it. It is difficult to define, although it seems to include everything that a person believes in, regardless of whether the beliefs are based on a specific god or not. In scholarly analysis, it is often classified as a sociocultural phenomenon, one of the many aspects of human society that are culturally shaped and maintained.
Sociologists, anthropologists, and historians have various theories on the origin of religion. Some, such as the anthropologists William James and Charles Horton Cooley, believe that religion was created to serve an evolutionary need; that is, it provided people with an explanation for the existence of life, death, and other natural phenomena. Others, including the theologian Karl Marx, have argued that religion evolved as an expression of the human need to find meaning in life.
Religious beliefs and practices vary widely from one culture to another, but some of the key elements are generally shared by all religions. They involve a belief in a supernatural being or beings, a belief in an afterlife, and a ritualized way of life that includes worship, prayer, meditation, morality, and participation in religious institutions. Religious practices may also involve sacred texts, symbols, and holy places, and may attempt to explain the creation of the universe and other phenomena in terms of a higher power or order.
Moreover, most religions are designed to protect and transmit goals that are perceived as of profound importance by their followers. Some of these goals are proximate and can be attained during this life, such as a more meaningful and fruitful way of living; others are ultimate in nature and have to do with the final condition of the individual or the cosmos (eschatology).
In addition, religion teaches a system of morality that is intended to guide behavior and foster a positive social structure. Because of its wide range of functions, religion is an important aspect of most societies throughout the world and has significant consequences for both individuals and groups. Sociological perspectives on the study of religion expand on these effects and provide further insight into this complex phenomenon.
