The aim of this paper is to present a map of Postcolonial Feminisms which are generated by the critical consciousness of the imperialist racism of Western Feminisms. Postcolonial Feminisms are classified into Black Feminism, Third World Feminism, and Global Feminism. While exploring the difference among these three streams, this paper proposes an aesthetics of diaspora as a common ground of mapping them. This map would locate the critical meanings of sporadic literary criticisms on the english literature from the perspective of postcolonial women. Black Feminism illuminates both the racism of white men and women and the sexism of black men by focusing on the cultural politics of race and gender through the diasporic experiences of deracination and slavery. As a means of recovering black femininity, some Afro-American feminists pay attention to black women`s literature which provides new configurations of black women. This approach, however, tends to overlook the imperialistic mechanisms of the `racialized` capitalism. Third World Feminism emphasizes the locality of third world women as a site of resistance to the imperialistic capitalism. Here, the issue of how to represent the native woman exposed to the cultural discourses of third world nationalism and western imperialism is crucial. She is not pure but corrupted. This means she is already diasporic. Against the localized resistance, Global Feminism insists on the global frame of resistance and solidarity among women communities of various diasporic minorities, which makes us comprehensively recognize the literature of diaspora. To intersect globality, locality, and ethnicity from the perspective of the third world women would be a fruitful way of decolonizing.
