Miller examined both the psychological and sociological makeup of his troubled characters. His heroes are common men who relentlessly pursue either their firm convictions or their misguided illusions. Using family relationships as starting points, Miller’s plays confront moral dilemmas, focusing on the individual’s responsibility to be true to himself or herself as well as part of the human race. His concern with the ordinary individual’s struggle for self-definition in a troubled world not only made him a renowned American playwright but gained for him a worldwide reputation as well. He is one of the most frequently studied playwrights in the American canon.
