《孤独的伦敦人》揭示了生活在伦敦的特立尼达离散群体面对多元文化冲突时作出的不同选择及后果。本文在文本细读的基础上结合霍米巴巴的后殖民理论,试图分析离散群体的不同选择如何导致身份危机以及如何相反地促成身份构建。离散群体在面临文化冲突时应积极化解二元对立,做双方文化沟通的桥梁,在文化融合中构建新身份。 Alone Londoners reveal the different choices and consequences of discrete Trinidad groups living in London in the face of multicultural conflicts. This article, based on a close reading of the text, combines with Homoebal’s postcolonial theory to try to analyze how the different choices of discrete groups lead to identity crises and how, on the contrary, they lead to identity building. In the face of cultural conflicts, the dispersed groups should actively resolve the binary opposition, build a bridge of cultural communication between both parties and build a new identity in cultural integration.
