When Frankl first arrives at Auschwitz, he is forced to surrender his unpublished manuscript on logotherapy. Over the course of his time in the four camps in which he is imprisoned, Frankl realized that he badly wanted to rewrite this manuscript, and further, that he wanted to write another manuscript about psychology within concentration camps. Frankl turned his thoughts toward the manuscript when he was struggling, and used it as way to keep himself motivated to stay alive. For example, when one of his camps was infected with typhoid, Frankl wrote keywords from his manuscript on scraps of paper to keep his mind alert. In the second half of the book, Frankl uses the manuscript to symbolize hope for the future and the importance of having something outside of oneself to live for.
