Religions have been one of the major forces in human history, shaping knowledge, the arts and science, and the development of social and political institutions. They have been instruments of liberation and coercion. They have been a source of inspiration for art and architecture, music and dance, poetry, drama and the explorations of nature that issued as the natural sciences. They have provided moral criteria and regular practice that inoculate individuals against a variety of social problems, including suicide, drug addiction, out-of-wedlock births, crime and marital breakdown. They are a source of strength for people in times of need and provide the hope of an afterlife.
Sociologists use the term religion to describe a broad range of belief systems that are shared by a group. These beliefs and practices can vary widely from one culture to another, but they all share certain characteristics. These include beliefs about the nature and origin of life, morality and the afterlife, the role of community and the significance of certain rituals or ceremonies. Most of the world’s population today belongs to a religious organization.
The term religion has been challenged in a number of ways, and it is possible to argue that there is no such thing as a religion. Some critics have gone so far as to say that the word religion is an invention of modern European colonialism, and therefore that people should stop treating it as if it corresponded to something real.
Others have argued that religion is an intrinsic part of human nature, and that humans are born with the urge to seek meaning in their lives and to develop protective systems against the dangers that surround them. Religions are early and successful examples of these protective systems, and they also serve as vehicles for the exploration of the human mind, body, environment and society.
A key function of any religion is the provision of a set of values that can guide an individual’s behavior in difficult circumstances. Religions may also offer a framework for moral evaluation, and they may teach about the responsibilities of family members, colleagues and citizens in the service of society. In addition, most religions include a promise of rewards in the afterlife for those who live according to its teachings and rules. These rewards may be material, psychological or spiritual. For many people, these rewards are the reason for their devotion to a particular religion.
