ABSTRACT
In Chapter 4 we considered plans in the service of goals without considering where those goals came from and how they might later be modified. Sometimes the reader of a story doesn't know or care about goal evolution, since it is permissible for storytellers to introduce more or less arbitrary goals into story fragments. Readers are prepared for the possibility that minor characters may want to go to Budapest, or punch a bartender in the nose. The reader doesn't care if he never finds out what intentions underlie these actions or what eventually happens to the characters in question. Indeed, in Chapter 7 we introduce a dragon who ‘steals Mary from the castle’ for reasons never explained beyond whatever can be vaguely inferred from the general nature of dragons.
