In the book "Why I Don't Write Like Franz Kafka" by William S. Wilson, the author explores the concept of pain as a source of knowledge and self-discovery. He describes an experience where he identifies a specific pain in his side, which he methodically examines and categorizes alongside other discomforts. This act of isolating the pain allows him to develop a deeper understanding of his body and its sensations.

Wilson conveys that pain serves a purpose; it provides valuable insights into the condition of his body. As he reflects on this process, he realizes that the overwhelming feelings associated with pain can blur his awareness, making it difficult to maintain a clear perception of his bodily boundaries. In this way, the text articulates a journey of mapping personal experiences through the lens of physical pain.
