The question of material reality throughout postcolonial fiction often seems shrouded in contention because of postcolonialism’s reliance upon poststructuralism; however, as evident throughout postcolonial fiction, materiality has always and continues to be a major component of poststructuralism, which becomes recognizable through the often-systemic approach to deconstructing colonial logic. This project approaches materiality through an analysis of the materiality throughout poststructuralism and application of new materialism, particularly regarding the insight quantum physics creates ontologically and epistemologically. By reading four postcolonial novels, I argue that postcolonial fiction makes and marks a post-Cartesian logic that coincides with the revelations of quantum physics.
