"A Farewell To Arms" : This essay shows how existentialism ties into the novel and gives description of important events.

This novel shows the existentialist way of thinking in the way that each person's life in the war was unique and the existence of that individual is unexplainable. Each move and each act is that person's responsibility, which may lead to something else, sometimes the difference between life and death. There is no God to watch over man, to dictate morality, or to reassure justice. Instead, the universe is indifferent and hostile to a soldier's …

…way of thinking that was being portrayed throughout the story, because it was so unexplained, and unorderly. Things like this happen without reasoning and shows how random the world's events can be. In the end this book seems to show that even the heroes cant always win. It is impossible to win this struggle. The world challenges Henry and Catherine's love many times, and in the end they seem to win, until Henry loses everything.
