Breaking down the question
The statement bundles two claims that must be prised apart. The first asserts that the Indian caste system is unique — a social form with no genuine parallel elsewhere. The second, and more provocative, claim is evaluative: that this alleged uniqueness has been unhealthy for the growth of sociology of India. The directive phrase, how far do you agree, invites a graded judgement rather than a flat yes or no.
The key analytical move is to notice that uniqueness is not a self-evident fact but a proposition built by particular scholarly traditions — Orientalist, indological and, later, structuralist. If caste is treated as sui generis, then Indian society becomes exceptional, resistant to the comparative and universalising ambitions of the discipline. The examiner wants you to weigh whether the emphasis on uniqueness enriched or impoverished Indian sociology.
How to approach it
Organise the answer around three questions. Is caste unique? Did the uniqueness thesis harm sociology of India? What is a balanced position?
Begin by reconstructing the case for uniqueness. Louis Dumont, in his structuralist reading, treated caste as the expression of a distinctive ideology of hierarchy rooted in the opposition of the pure and the impure, with the Brahmin encompassing the king. For Dumont, Homo Hierarchicus stood opposed to the Homo Aequalis of the egalitarian West. G. S. Ghurye earlier catalogued features — segmental division, hierarchy, restrictions on commensality, civil and religious disabilities, endogamy — that seemed to mark caste off from class.
Then present the critique. An obsession with the unique fosters what has been called the book view — an understanding of caste drawn from Sanskrit texts and the varna model rather than from observed social life. This textual, indological bias arguably delayed empirical fieldwork, encouraged an ahistorical and static portrait, and cut Indian sociology off from comparative theory.
Finally, mount the counter-argument. The field view associated with M. N. Srinivas, and concepts such as sanskritisation, dominant caste and the jajmani system, showed that caste could be studied empirically and comparatively without denying its specificity.
Model answer
The proposition that caste is unique has a long pedigree. Orientalist scholarship and the indological method of Ghurye read caste primarily through classical texts, presenting the varna order as timeless and pan-Indian. Dumont raised this to a theoretical pinnacle: caste was the sociological embodiment of a hierarchical ideology, qualitatively different from the stratification of egalitarian, individualistic societies. On this view India is not merely different in degree but different in kind.
There is genuine warrant for the uniqueness claim. The ritual idiom of purity and pollution, the linkage of ritual status to occupation, the density of endogamous jatis, and the religious sanction of hierarchy do distinguish caste from Western class. To flatten these into a generic model of stratification would lose what is sociologically distinctive about Indian society.
Yet the second half of the statement carries real force. When uniqueness hardened into an assumption, it produced several distortions. First, it privileged the book view — caste as prescribed in the shastras — over the lived, negotiated caste of the village. Second, it encouraged a static, essentialist picture that underplayed mobility, conflict and change, and neglected the colonial state's role in reifying caste through census and ethnography. Third, and most damaging for the discipline, it fostered Indian exceptionalism, insulating the study of caste from comparative and theoretical currents in world sociology, and inviting an indigenist claim that only Indian categories could explain Indian society.
The corrective came from within. Srinivas replaced the book view with the field view, grounded in intensive village studies. His concepts — sanskritisation, dominant caste, the vertical solidarities of the jajmani system — treated caste as a dynamic, changing institution amenable to observation and generalisation. Andre Beteille, in his study of Sripuram, disentangled the axes of caste, class and power, showing that caste could be analysed with the universal tools of stratification theory while still respecting its ritual specificity. Comparative sociologists such as Gerald Berreman drew parallels between caste and race, and Leach edited comparative work on caste beyond India, demonstrating that caste need not be a conceptual island.
A balanced judgement, therefore, agrees only partially with the statement. Caste is distinctive, and to deny its specificity would be poor sociology. But uniqueness as such was not the disease. The malady lay in a particular, textual and essentialist handling of that uniqueness, which for a time tied Indian sociology to an indological and exceptionalist frame. Once the field view, the comparative method and historical sensibility were brought to bear, the very distinctiveness of caste became a resource for theory rather than an obstacle. The distinctiveness of caste enriched sociology of India; the dogma of incomparable uniqueness, for a while, constrained it.
Examiner's perspective
A strong script resists both extremes — neither celebrating caste as gloriously unique nor dismissing the uniqueness thesis outright. The examiner rewards the crucial distinction between distinctiveness (which is defensible) and incomparable uniqueness (which is problematic), and looks for the book view versus field view contrast handled with named thinkers. Weaker answers merely list features of caste from Ghurye and stop. Higher marks come from showing how the indological legacy shaped, and at times stunted, the discipline, and how Srinivas, Beteille and comparative scholars restored its analytical health. A clear, qualified verdict at the close — partial agreement with reasons — signals maturity. For the conceptual scaffolding, see the note on perspectives on caste.
