Paragraphs 15–16 assist to build the fundamental theme since Wiesel refers to the Holocaust in Auschwitz by suggesting, ironically, that if governments throughout the globe had realized what was happening to Jews under Hitler's authority, they would have aided them. By doing so, Wiesel claims that they would have saved many more lives than they did. Paragraphs 15 and 16 also relate to the central idea because they both deal with explaining why it is important to remember history. Paragraph 15 explains that remembering history prevents it from happening again, while paragraph 16 states that forgetting history leads to more violence. These two ideas are opposite sides of the same coin; if we forget what happened in the past, then it cannot prevent something like it from happening again. However, if we remember what happened then it may help stop future violence. Finally, paragraphs 15 and 16 contribute to the development of the central idea because they both explain how remembering history can help us avoid future violence. Paragraph 15 suggests that remembering history can help us avoid future violence by preventing it from happening again. This makes sense because if we forget what happened in the past, then we can't take steps to prevent something similar to it happening again. Paragraph 16 adds that remembering history can also help us avoid future violence by helping us resolve our differences peacefully.
