Abstract:- Arthur Miller is one of the most successful and remarkable dramatists of the postwar era in America. His works not only throw lights on the middle class anxieties brought on by a society that emphasizes the hollow values of material success but also appeal to human hearts and minds universally. His other important works are ‘The Man Who Had all The Luck’(1944), ‘All My Sons’(1947), ‘The Crucible’(1953), ‘A View From The Bridge’(1955). He won the Pulitzer Prize and Tony Award for ‘Death of a Salesman’. The present research paper is an sincere effort made to discuss the significance of the concept of Disillusionment and the Feeling of Certitude as tragic features in the play ‘Death of a Salesman’ written in 1949 by Arthur Miller, American dramatist. In the play, the protagonist, Willy Loman who is a salesman and quite old now, possesses the dreamy desires and emotions throughout the life. He pretends to be a successful salesman but such instincts are nothing but the illusion and prejudices which turn into disillusionment and lead him towards frustration and the sense of loss of identity. The researcher intends to reveal the bitter truth of human life through the mental deterioration and superficial doctrine for success of Willy Loman due to the disillusionment and the feeling of certitude.
