Psychoanalytic criticism views literature through the lens of Sigmund Freud's theories of the mind. According to this reading of Arthur Miller's Death of a Salesman, Willy Loman unconsciously uses defense mechanisms like denial, avoidance, and regression to protect his fragile identity and avoid admitting his and his son's failure in the business world. Marxist criticism sees the play as critiquing capitalism's promotion of consumerism and false ideals of self-worth through economic success, which keeps Willy striving to live up to his predatory brother and buying what he cannot afford.
