This study aims to explore Toni Morrison’s cosmopolitan vision in Tar Baby by focusing on the construction of Jadine’s identity as a cosmopolitan subject. In most novels, Toni Morrison usually deals with issues of African American identity in the white-dominated American society, pursuing the identity politics. However, she reveals a cosmopolitan vision in Tar Baby by exploring the conflicts of two opposite values, Black nationalism and cosmopolitan ideas represented by two main characters. Morrison criticizes exclusive and male-centered Black nationalism represented by Son, and characterizes Jadine as a ‘restless’ subject on the ‘routes’ of identity in the conflict and hybridity of black and white cultures. Morrison shows a cosmopolitan vision by stressing Jadine’s unstable identity on the ‘routes’ in the conflicts of various values related to race and sex. Jadine resists the black traditional values which oppress female sexuality and force women to prioritize the roles as a mother and a daughter. She pursues a cosmopolitan life in which she makes a success by utilizing the benefits provided by the white world and being willing to accept the unstable but independent life. Seemingly, the process of her identity and self-realization is dominated by white values, but Morrison suggests the possibility of her change by emphasizing her contact with the black culture and the powerful impact it has on the construction of her identity.
