Death of a Salesman addresses loss of identity and a man's inability to accept change within himself and society. The play is a montage of memories, dreams, confrontations, and arguments, all of which make up the last 24 hours of Willy Loman's life. The three major themes within the play are denial, contradiction, and order versus disorder.
Each member of the Loman family is living in denial or perpetuating a cycle of denial for others. Willy Loman is incapable of accepting the fact that he is a mediocre salesman. Instead Willy strives for his version of the American dreamsuccess and notorietyeven if he is forced to deny reality in order to achieve it. Instead of acknowledging that he is not a well-known success, Willy retreats into the past and chooses to relive past memories and events in which he is perceived as successful.
For example, Willy's favorite memory is of Biff's last football game because Biff vows to make a touchdown just for him. In this scene in the past, Willy can hardly wait to tell the story to his buyers. He considers himself famous as a result of his son's pride in him. Willy's sons, Biff and Happy, adopt Willy's habit of denying or manipulating reality and practice it all of their lives, much to their detriment. It is only at the end of the play that Biff admits he has been a "phony" too, just like Willy. Linda is the only character that recognizes the Loman family lives in denial; however, she goes along with Willy's fantasies in order to preserve his fragile mental state.
The second major theme of the play is contradiction. Throughout the play, Willy's behavior is riddled with inconsistencies. In fact, the only thing consistent about Willy is his inconsistency. From the very beginning of Act I, Scene 1, Willy reveals this tendency. He labels Biff a "lazy bum" but then contradicts himself two lines later when he states, "And such a hard worker. There's one thing about Biffhe's not lazy."
