Willy is not an invincible father or a loyal husband or a fantastically successful salesman like he wants everyone to believe. He is self-centered. He fails to appreciate his wife. And he cannot acknowledge the fact that he is only marginally successful. Hence, Willy fantasizes about lost opportunities for wealth, fame, and notoriety. Even so, it would be incorrect to state that Miller solely criticizes Willy. Instead, Miller demonstrates how one individual can create a self-perpetuating cycle that expands to include other individuals. This is certainly the case within the Loman family. Until the end of the play, Willy effectively blocks the affair out of his memory and commits himself to a life of denial. He cannot remember what happened, so naturally he does not understand why his relationship with Biff has changed. Willy wants Biff's affection and adoration as before, but instead the two constantly argue. Willy vacillates, sometimes criticizing Biff's laziness and ineptitude, other times praising his physical abilities and ambition.
Linda and Happy are also drawn into the cycle of denial. Linda is aware of Willy's habit of reconstructing reality; however, she also recognizes that Willy may not be able to accept reality, as shown through his numerous suicide attempts prior to the beginning of the play. As a result, Linda chooses to protect Willy's illusions by treating them as truth, even if she must ignore reality or alienate her children in doing so. Happy is also a product of Willy's philosophy. Like Willy, he manipulates the truth to create a more favorable reality for himself. For example, when Happy tells everyone that he is the assistant buyer, even though he is only the assistant to the assistant, he proves that he has incorporated Willy's practice of editing facts.
