Objective Story Line • the plot as it concerns the story goal • The Objective Story Line is a distinct act by act sequence of events that involves all of the Objective Story appreciations and none of the Subjective Story appreciations. It represents the dispassionate argument of the story, emphasizing events and relationships in a purely cause and effect way. This is not to say that it has nothing to do with the meaning of a story, only that it is not the WHOLE story. Meaning in stories comes from comparing the Objective view of a story with the Subjective view that comes from within the story.
