In discussing the definition and history of cults, the author notes that the basic meaning of "cult" is "the worship of a deity or the rituals of that worship." Historically, the term cult has been used to refer to unorthodox or unconventional groups whose beliefs are different from the traditional and dominant religions of the society in the which the cults exist. The use of the term as a derogatory stereotype increased through the 1970s as the anticult movement grew. Descriptions of particular cult movements encompass "The Children of God," cults based on eastern religious ideas, transcendental meditation, the Unification Church, magic and occult groups, Satanism, Santeria and religious freedom, and cults and violence. The second chapter examines reasons why people join cults, followed by a chapter on the nature of life in a cult. Another chapter focuses on the organization of a cult, with attention to the role of leaders, authority, and dissent. The fifth chapter addresses how cult leaders and members view the world outside the cult and how the outside world views cults. The final chapter discusses issues involved in leaving a cult, including typical reasons for leaving, fears about leaving, difficulties in leaving, and adjustments required after leaving the cult.
