Emotion.

In the third chapter of Leonard Schlain's book, he talks about the evolution of males in the use of emotion. While hunting they perfected the use of the left brain which allowed them to kill without emotion. This of course, lent the male population to excel at the task of speech and writing.

When reading this, I started thinking about certain types of writing that induce emotion. Some very emotional pieces must use some characteristics of the oral based thought process to induce such reactions. This is another example of how the literate and oral traditions are not opposing, but are seen together.
