Macrostructure 1 and its descent into evil
Macrostructure one used to be a kindhearted, loving soul whose only purpose in life was to create a heirarchy in order to increase comprehension among basal readers by using the powerful gift that he was born with: rhetorical function. However, rhetorical function can be used both for good and for evil. In the good old days, phrase-structure grammars applied to all sentences, so that story schemata would specify a set of rewrite rules for decomposing relations among propositions in a story. However, a new wind was blowing: all that was about to change.
Macrostructure 1 was born on his family's tree farm. As a child, he would wake up and take care of the trees in order to preserve their health. These trees were later used to benefit the basal readers in order to improve their understanding. His parents' dream was to improve the social-economic status of all and to create equality. When macrostructure 1 hit puberty, however, his attitude began to change. He stopped getting along with his sister, Causation. One day Macrostructure 1 took Causation out clamming, to a beach she had never been to before. Here, he was able to lose her. He returned home and told his parents that she hadn't come home from school that day and didn't know where she was.
Without Causation, the tree farm ceased to flourish. Implied links between higher and immediately lower level events were disabled, not allowing or compelling B to occur after A. In addition, some grammars ceased to establish intracategory connectors to allow for explicit logical connection between events or states at the same level in the heirarchy. This was a sad, sad turn of events. The trees withered and died. The story grammarians, noticing a violation in the well-fomedness of stories, shut down the tree farm and forced the family to move away from their beloved home.
Causation, in the meantime, had established herself by opening a small clamming restaurant in the harbor. She learned about the closing of the tree farm in the papers and realized that she had to do something in order to save text-comprehension. However, as she didn't have any trees to work with, she realized she would have to come up with a new method. Brilliant as she was from years of studying by the firelight, she came up with canonical story structure. First, she used her canons to destroy hopelessly incoherent themes. Then, she knitted themes that would coherently function with the schemata of the basal readers to distribute to the public. She realized that Macrostructure 1 had hopelessly descended into evil, but realized that she had the power, if she kept trying, to vertically and horizontally imply heirarchical relations by explicit links in grammar.
The moral of this story is obviously that if you are true to yourself, then attention to cohesion rather than atomization of sentence elements will pay greater dividends.
The end.
