The present paper deals with the aspects of ‘Binary oppositions’ and ‘Duality’ employed by one of the most famous diasporic and post-colonialist novelists Salman Rushdie in his two popular novels Midnight’s Children and Shame. The characters are the specimen of these aspects, especially Saleem who is closely associated with Shiva, who is just like his alter ego. The duality between them is unavoidable because they cannot be separated from each other. Both these novels are rich in terms of binary oppositions as these help the readers in understanding the history. Although both these novels are different in the subject matter, yet the aspects of dualities and binary oppositions are quite apparent. These two novels have the similar historical frameworks, and have same fundamental concerns. Both these novels have the expressions of the transformations that colonialism has brought. Thus, the topic is chosen to discuss these aspects in a feasible length.
