Decolonisation is being embraced as an imperative within Higher Education, yet many institutions have struggled to formulate a coherent response. This article reports on a case study of a research-intensive South African university where the call for decolonisation emerged amidst considerable conflict on campus. The research takes as its departure point the notion that the discourse on decolonisation, thus far dominated by calls to re-examine Western ways of knowing, would nonetheless benefit from perspectives grounded in the paradigm of critical realism and from a social realist analysis. It found that an intellectual and cultural solipsism, as a form of fractured reflexivity, rooted in social and cultural identity, played a causal role in constricting the collective reflexivity of the corporate agents that shape the Western academic environment, resulting in a reproduction of an exclusionary intellectual and cultural environment.
