This article is a general overview of the ideas that teachers could use to teach the numerous slave narratives in U.S. literature by highlighting the similarities and differences that the authors used to depict the audacities of slavery. One of the main ideas is that the author does not have to go into grave detail of the violence that slaves experience to get the point across that it is morally unacceptable. This is another way of framing the experiences of slaves to where the expected silence is not broken, but they story is still heard.  Dunham's A Journey to Brazil cannot be a decided anti-slavery text, but the examples of the brutality inside slave systems has an abolitionist undertone. The contemporary readers of Dunham will take his humanitarian ideas and apply them to the relevant issue of slavery, breaking the ignorance cycle that is occurring all over America at this time. This is contradictory to American literature pieces like Uncle Tom's Cabin and Incident's of a Slave Girl, which are obvious anti-slavery pieces that depict every detail of the cruel violence that slaves encountered in everyday life. 
Even though A Journey to Brazil is a tale of slavery in the Americas outside of the U.S., it is related to how the stories of the United States slaves impacted the views of foreigners on various slave systems. The slave narratives of the American slaves give light to the inside cruelty, and it is impossible for this system to continue without the dependence of the "transitional exchange of people, ideas and technologies.” The slavery inside the U.S. is often compared to slavery in other countries as being more degrading and cruel than the foreign slave systems. This voiced to the American public that the ignorant ideas of African Americans being complacent with their state in life.
