This thesis evaluates tragic characters from three representative tragedies, Macbeth, Antigone, and Death of a Salesman, in terms of Lawrence Kohlberg's six stage theory of moral development. A tragic character's moral judgment is described as being founded on universal values and principles which determine stage placement. The tragic situation is precipitated by conflict experienced by a character between his present stage form of evaluation and the more preferred, differentiated and integrated form of the next higher stage. Since Kohlberg's theory is cognitive-developmental with the moral principle of justice emerging autonomously at the stage six level, its application aids in supporting a view of tragedy based on a moral order having justice as its highest principle and on a continuity independent of historical and cultural influence.
