This paper looks at the meaning and formation of the diasporic identity using the analogy of the body in British diaspora literature. Futhermore, it examines how the body can move in any direction in order to seek a positive multi-cultural society. This paper analyzes the body of diaspora from the colonial era to the recent past through diasporic writer Zadie Smith’s White Teeth. First, the way in which the body in the Biritish colonial era is portrayed as a “suffering body”, an “imprisoned body”, and then as a “treated body” is assessed through different perspectives. Second, the voluntarily diaspora for the UK’s industrial workforce after World War II is analyzed in terms of the social and cultural conflicts of the diaspora between their home country and their assimilation into their host country. Finally the “body” of the second generation of the diaspora is portrayed. This “body” undergoes much more complex patterns of change than the first generation so the analysis of this takes into account how this complex aspect is represented by its identity, and relationships between the diasporic community and traditional societies in Smith’s work. This study furthers the understanding of the identity and problems diaspora through use of the analogy with the body and it helps provide an opportunity to recognize the value of “harmony” in the age of globalization.
