本文以亞瑟•米勒之現代劇《推銷員之死》爲探究對象，分析亞瑟•米勒文本中所勾勒的成功夢，探討米勒如何瓦解美國成功今財夢的神話、如何營造一個屬於二十世紀美國平几小人物之現代悲劇。藉此觀察，本文將更進一步檢視美國成功夢與美國現實之間的巨大鴻溝。

Arthur Miller's Death of a Salesman delineates a tragedy of a common man in the twentieth-century American society. Willy Loman, the protagonist of the play, is a believer of the American dream of success. His fidelity to the great dream of success constitutes the very heart of the play. However, championing these ideals of success, Willy is driven to madness and despair by his inability to achieve success economically in a society that seems to guarantee success. In this paper, what I am attempting to explore is the reasons why Arthur Miller arranges such an ending. How does Arthur Miller present Willy's dream of success and his nightmare of defeat? And what exactly is Arthur Miller's attitude toward Willy and his society? Thus I am inquiring into the immense gap between the American dream of success and the American reality.
