A work of literature can be defined as a classic because it promotes an in-depth understanding of human behavior. The Scarlet Letter, by Nathaniel Hawthorne, and One Flew Over the Cuckoo's Nest, by Ken Kesey give the reader a complete understanding of what is going on in the heads of the characters. This character overview can be used as a general overview of human behavior. One idea is that a person's physical abilities can be controlled by their mental awareness and state of being. Another is that they perceive themselves in relation to those around them. In The Scarlet Letter, the reader is confronted with the feelings of Chillingworth, Hester's husband (the main character), and Dimmesdale (Hester's adulterous partner), as they are also mentally destroyed. asphysically. Chillingworth is afraid of being disgraced by being known as the husband of a whore. He also wants revenge on Dimmesdale for corrupting Hester. His thoughts are read by the reader and his actions represent the evil ways that defeated him. The way he torments Dimmesdale is visible when he acts as a doctor. Chillingworth knows that Dimmesdale was the father of Hester's daughter Pearl. But he wants to torment and take revenge on Reverend Dimmesdale, who has suddenly fallen ill. Chillingworth uses his knowledge of the human mind and medicine to deduce that Dimmesdale's illness did not reside in his body, but in his mind: he held a secret, a deep, dark, secret, that was destroying him. Asking Dimmesdale if he was hiding something in the middle of a paper, I realized that people sometimes seem different because of the power or freedom they hold. Perhaps he knew that they only saw themselves in relation to others around them. It is possible that he expressed these ideas in his book, using the Chief and McMurphy as subjects in the situations previously described. If a work of literature shows a deep understanding of human behavior, as The Scarlet Letter and One Flew Over the Cuckoo's Nest do, then that work can be considered a classic, as those of Hawthorne and Kesey are. The main commonality is that both authors realized that mental and physical conditions are interrelated and dependent on each other. Kesey also showed how a person sees things in perspective in relation to their surroundings..
