《土生子》的主人公别格通过对白人和命运的反抗刷新了读者一直以来心目中逆来顺受的黑人形象,然而最终还是难逃命运的魔爪。后殖民语境中的东西方二元对立关系为分析别格的身份认同问题提供了一个切入点。白人眼里的别格即西方眼里的东方,而“他者”是美国主流社会对别格的定位,在此前提下塑造出的是别格非正常的“自我意识”。因此,别格及其所代表的广大黑人的悲剧是“自我”与“他者”双重身份建构下的悲剧。 The protagonist of “native son” flirted with the fate of the whites and refuted the black image that readers had long been obsessed with, but in the end they were still unable to escape the fate of fate. The dichotomy between East and West in the context of post-colonialism provides an entry point for the analysis of Pythagorean identity issues. In the eyes of the white man is the east in the eyes of the West, while “the other” is the dominant position of the mainstream American society on the basis of which the abnormal “self-awareness” is shaped. Therefore, the tragedy of Biege and the majority of Negroes represented by it is the tragedy under the dual identities of “self” and “other”.
