In order to formulate a thesis statement for Elie Wiesel's Night, we need to consider Wiesel's purpose for writing a memoir detailing his firsthand experience of the Holocaust. A good thesis statement will always make an original and compelling claim about the text at hand. Most importantly, a good thesis statement will always be supported by textual evidence.
Firstly, it can be argued that Wiesel needed to share his experience in the concentration camps because his act of storytelling was a powerful way for him to process the trauma he had endured. On writing Night, Wiesel questions,
Did I write it so as not to go mad or, on the contrary, to go mad in order to understand the nature of madness?
Here, Wiesel identifies two possible purposes for writing his memoir: he wrote it out of necessity, for if he did not, the memories (and not sharing those memories) would cause him to "go mad." Secondly, he wrote it to re-enter that state of madness as an attempt to better understand what happened to himself, his family, and his fellow prisoners. What's more, the act of writing, especially for Wiesel, allowed him to reclaim a voice the Nazis stole. Wiesel was deeply silenced during the Holocaust, and writing was his way of fighting against this silence.
Secondly, one could argue that Elie Wiesel felt obligated to write Night because he was one of the few survivors who lived to tell the tale. In this way, he could ensure that the memories would never vanish. Wiesel powerfully states,
For the survivor who chooses to testify, it is clear: his duty is to bear witness for the dead and for the living. He has no right to deprive future generations of a past that belongs to our collective memory. To forget would be not only dangerous but offensive; to forget the dead would be akin to killing them a second time.
Night ensures that members of future generations will never forget what happened to six million Jews and other marginalized peoples. After his liberation, Wiesel felt that he had a profound purpose for surviving, and that was to share his story and honor those who did not make it.
A final example of a thesis statement for Night would be that Wiesel's story provides a powerful example of the strength and resilience of a father-son relationship in the face of ultimate horror. Wiesel's memoir is all about relationships: his relationship with himself and his relationship with his family. Wiesel details numerous examples of how his relationship with his father in the camps both faltered and flourished—from the first harrowing day faced with the camp's dehumanizing selection process to his father's death, which left Wiesel feeling hopeless and alone. Wiesel writes,
After my father's death, nothing could touch me any more.
Night is full of poignant examples of Elie's unbreakable bond with his father, even in the most nightmarish and destructive circumstances.
