I in chapters 14-17 the narrator leaves his primary thread and begins to tell us of his brother’s experiences. This radically changes the point of view. We can easily understand this as a second-hand narrative. These chapters are more authoritative than hear-say, because the narrator takes time to build his ethos—or his credibility for telling his brother’s tale. How does the narrator build his ethos/credibility throughout the text? Why are we inclined to believe him? Does he sustain his credibility? How does his continued introspection lend itself to the narrative and to his credibility?
