When we go to the theater, we may have passing interest in the construction of the set and stage works, but we understand that the play exists in the roles of the performers. When a person comes late and asks what has happened so far, the question is not answered by information about the costume designer, script writer and the hiring of the cast. Telling the person about all that would be offering the wrong sort of origins information. Some sorts of origins are more important than other sorts of origins.
