Untouchability, a social practice deeply embedded in hierarchical caste systems, refers to the systematic exclusion and dehumanization of certain groups, often rationalized through religious or cultural beliefs. This theme has been examined by a range of authors, from Mahatma Gandhi, who denounced it as a moral failing intertwined with colonial exploitation, to Bhimrao Ambedkar, who contended that genuine reform necessitated the eradication of caste-based mindsets rather than merely altering superficial social customs.
Western writers like Charlotte Brontë and John Milton, although not addressing caste directly, explored themes of oppression and moral defiance, while H. B. Marriott Watson depicted societal outcasts through metaphor. These differing viewpoints highlight untouchability’s lasting significance as a critique of injustice and an appeal for ethical unity across cultures.
