The defining qualities of a hero are constantly changing. At one time, the ideal hero might be courageous. At another time they might be passive. It all depends on what the people need in that moment.

The heroes of the various periods throughout time help to shape the American voice, and this is reflected in the literature. When the hero is bold, the voice of the people is bold. If the hero changes the voice changes, and if the voice changes, the writing changes. These elements are tightly woven and can provide a better understanding of America at different points in time.
