Social exclusion is a practice that is evident in human societies across ages. It had many aspects and facets based on the social, religious, political, economic and cultural parameters which were followed in the societies. With modernisation (in the sense of scientific inventions became a part of everyday life), the concept of social exclusion got more organized in human societies. Notable social psychologist Susan Tufts Fiske lays out the framework of the practice called social exclusion among five core motives which are found among people which is called the BUC[K]ET theory. This article will discuss these core motives and will investigate how they are imprinted in the socio-cultural behaviours of human beings through select twentieth-century Bengali literary texts. The article will be interdisciplinary and qualitative in nature.
