For things that cannot be explained, legends, narratives, and myths are created to explain events that are beyond scientific measurement. When an occurrence cannot be quantified or proven, like a belief or the story of an ancient mythological creature, stories answer questions that others have, and these stories can live through many more generations. Cultures create stories that may differ even though they may be about the same subject or person. Determining the way a person acts, such as what qualifies the traits of a student, teacher, or parent cannot be scientifically quantified, therefore people create narratives based upon what they see or what their environment molds these people into.
Lyotard breaks down the barriers of beliefs and narratives that foretell the reason why things happen the way they happen. Postmodernism puts a quantification to everything, destroying these grand narratives that had once been created off mystery and seemingly elderly wisdom. He says that knowledge will cease to exist unless it can be minimized to simply computer knowledge, meaning scientically quantifiable, straight forward, and factual information that does not thrive off of questioning or derive from a story or narrative.
Narratives can marginalize minorities and their discourses because certain narratives have been created through those discourses and have remained within that society of people. Mexican cultures have narratives that explain happenings and situations to children. Even though the ancestors weren't there to see these happenings take place, the narrative makes up for the loss of their presence and that narrative can still be taken for its truth. These stories remain within these communities and, therefore, marginalize them because it has been made a part of their culture.
Computer technology and efficient productivity is the representation of the world and what it is becoming in Brave New World. Lyotard presents the argument that the world will cease to function without this preciseness, though Huxley claims quite the contrary with his satirical exaggeration of this make believe world. These differing opinions, or conspiracies, whichever you prefer, make for a great argument based upon whether imagination and narratives is the DNA of our universe, or if preciseness and efficiency will create a happier, more desirable world to reside in.
