Breaking down the question
This is a conceptual comparison question wearing the clothes of an empirical one. The two key terms — hierarchy and differentiation — carry precise sociological meanings, and the whole answer turns on defining them correctly before you judge the direction of change.
Hierarchy, in Louis Dumont's usage, is a specifically Indian principle in which society is ordered by a single, encompassing value — the ritual opposition of the pure and the impure. Castes are ranked on one continuous scale, and the whole is prior to its parts. Differentiation, by contrast, is a feature of modern societies in which distinct spheres — economy, polity, religion, kinship — become functionally separate and are governed by their own principles. Occupations detach from ritual status; political power detaches from priestly rank.
The question — is Indian society moving from one towards the other — asks you to assess a structural transformation. The word illustrate is a direct instruction to supply concrete examples, so an answer built on abstractions alone will be marked down however elegant it sounds.
How to approach it
Begin by establishing the two concepts with their theoretical parentage — Dumont on hierarchy, and the broader theory of structural differentiation associated with modernisation. Yogendra Singh's framing of modernisation as differentiation-cum-integration is especially useful here and lets you anchor the answer in an Indian sociologist.
Then argue a qualified thesis rather than a simple yes. The evidence points towards increasing differentiation — but hierarchy has proved remarkably resilient, sometimes reasserting itself in new forms. The best answers hold both truths together. Supply examples on each side: the separation of ritual status from occupation, the rise of achievement-based mobility, and secularisation on one hand; the persistence of endogamy, caste in electoral politics and the substantialisation of caste on the other.

Model answer
Whether Indian society is moving from hierarchy towards differentiation depends first on how we understand those terms. For Louis Dumont, hierarchy is the organising principle of the caste system — a single ideological scale founded on the opposition of purity and pollution, in which every group finds its ranked place and the whole encompasses its parts. Differentiation, the hallmark of modern societies, refers instead to the separation of institutional spheres, each operating by its own logic and none subsuming the rest.
Judged by this standard, several powerful trends do point towards differentiation. The colonial economy, industrial employment and the modern occupational structure have detached work from ritual status; a person's caste no longer determines their trade, and new occupations carry no ritual ranking at all. The state has become a secular sphere in which political power is legitimised by votes rather than by priestly sanction, so authority is differentiated from ritual purity. Education, the professions and urban labour markets increasingly reward achievement over ascription, producing genuine social mobility. André Béteille's classic study of a Tanjore village captured exactly this — the historical convergence of caste, class and power giving way to their growing separation.
Yet it would be an error to read this as the simple replacement of hierarchy by differentiation. Hierarchy has shown striking resilience, and has in some respects adapted rather than dissolved. Endogamy — the marriage rule that anchors caste — remains overwhelmingly strong, so the reproductive core of the system persists even where its ritual functions weaken. M. N. Srinivas noted that caste, far from disappearing, became horizontally consolidated and politically mobilised; Dumont himself spoke of the substantialisation of caste, whereby castes come to behave less like ranked ritual orders and more like competing collective blocs. In electoral politics, caste identity has become a resource rather than an embarrassment, which is differentiation of function coexisting with the persistence of the group.
The honest conclusion is that Indian society exhibits both movements at once. Structurally, differentiation is unmistakable — the economy, polity and religion no longer form a single encompassing order governed by ritual value. Ideologically and in the sphere of kinship, however, hierarchy survives and mutates. Yogendra Singh's formula of modernisation as differentiation-cum-integration captures this well — the parts become distinct, yet older principles reassert themselves to re-integrate the whole in altered form.
Indian society is therefore not moving in a straight line from hierarchy to differentiation. It is undergoing differentiation of institutions alongside the transformation, rather than the erasure, of hierarchy. The pure-impure logic recedes from the occupational and political spheres even as caste consolidates as a horizontal identity — a dual process that any adequate answer must acknowledge.
Examiner's perspective
The commonest failure is treating the two terms loosely, as if hierarchy simply meant inequality and differentiation meant equality. Examiners want Dumont's precise sense of hierarchy and the structural sense of differentiation. The second discriminator is the thesis — a flat yes or no scores poorly, whereas a qualified argument that both processes operate simultaneously reads as mature sociology. Third, every claim needs an illustration, since the question demands it explicitly. Finish by naming Indian scholars — Béteille, Srinivas, Yogendra Singh — to show command of the domestic tradition rather than reliance on Dumont alone.
