Ernest Bormann called the wide-ranging body of people who shared a common symbolic reality as a rhetorical community.
Symbolic convergence theory (SCT), a general communication theory, explains how people in a small group , organization , or other rhetorical community come to share meanings, emotions, values, and reasons for doing things. Ernest Bormann, John Cragan, Donald Shields, and others came up with SCT. It is a message-centred theory that is based on observing symbolic facts in communication. Observers noticed that dramatised messages, which they called "fantasy themes," were shared in small-group communication, in mediated communication, and among the communicating members of organizations and other large publics ( Rhetoric and Narrativity; Storytelling and Narration). In each situation, researchers found that people shared, repeated, and wove together fantasy themes to create a larger, more complex view of reality called a rhetorical vision (e.g., the Cold War, global warming, or neo-conservatism). A rhetorical vision has many fantasy themes that show heroes and bad guys acting out dramatic scenes. This kind of vision gives a group its identity, unity, and culture.
