The purpose of the present article is to explore Homi Bhabha's notion of ambivalence in J. M. Coetzee's Disgrace, one of Coetzee's most popular works. The main concern of the article is to demonstrate how colonial authority is evidenced in Coetzee's Disgrace. After giving a general summary of Bhabha's postcolonial ideas and a brief synopsis of Disgrace, the researchers analyse the main character's conduct and relationships with other characters in terms of Bhabha's concept of ambivalence. The article shows that ambivalence destabilises the discourse of colonial authority and discloses the uncertainties and anxieties within colonial powers. It reveals that not only does Coetzee show traces of the coloniser's authority and white supremacy through David's demeanour and his relationship with non-white people, he also emphasises David's anxiety and uncertainty.
