Structural functionalism explains a social item by identifying what it does for the system in which it is embedded. Society is conceived as a system whose institutions — family, economy, polity, religion, education — are interdependent, so that a change in one reverberates through the others, and each persists because it satisfies some requirement of the whole. Explanation runs from part to whole: to ask what marriage is sociologically is to ask what work it performs in sustaining the arrangement of which it is a part.

The perspective couples a structural question with a functional one. Structure is the relatively stable pattern of relationships and positions that outlasts the individuals occupying them; function is the consequence of an activity for the maintenance of that pattern. Its founding image is the organic analogy: as heart, liver and lungs differ yet each keeps the organism alive, so institutions differ in form while cooperating in the survival of society. The analogy carries commitments that shaped everything the perspective later did — the whole exceeds the sum of its parts, systems tend towards equilibrium, normal states can be told from pathological ones — and it carries the difficulties too, since a body has no internal groups with opposed interests.

The lineage

Auguste Comte supplied the division between social statics and dynamics; Herbert Spencer developed the organic analogy, comparing the differentiation of institutions to that of organs as an organism grows in complexity. Émile Durkheim made the approach sociological rather than biological: in The Division of Labour in Society he distinguished the cause of a phenomenon from its function, argued that the function of the division of labour was solidarity rather than output, and read punishment as a reaffirmation of the collective conscience.

British social anthropology turned this into fieldwork practice. Bronisław Malinowski anchored institutions in basic and derived human needs, so that magic, myth and kinship each met a requirement of people living together. A. R. Radcliffe-Brown rejected the psychological detour, defining function as the contribution of a partial activity to the total activity of which it is part, with social integration as the condition to be explained. In American sociology Talcott Parsons built the most ambitious version — functional prerequisites, institutionalised roles, pattern variables and shared values — while Robert K. Merton, his student and critic, pulled the perspective back towards empirical research.

Core ideas

Four propositions recur. System needs or functional prerequisites: any society must reproduce its members, produce and distribute goods, allocate authority, transmit culture and manage tension, and its institutions are the answers it has found. Value consensus: members broadly share the ends their institutions embody. Socialisation: values are internalised in childhood, so conformity becomes preference rather than compulsion, and where internalisation fails social control restores the pattern. Together these yield equilibrium — not stasis, but a tendency to return towards balance after disturbance and to adapt through orderly differentiation rather than rupture.

Merton's refinements

Merton dismantled three postulates the perspective had carried uncritically: that every item is functional for the whole, that all items are indispensable, and that society forms a functionally unified whole. In their place he offered a working vocabulary. Manifest functions are recognised and intended consequences; latent functions are unrecognised and unintended, and it is these that reward sociological attention — as in his reading of the Hopi rain dance, which fails as meteorology while succeeding in reinforcing group identity. Dysfunction admits that an item may impair adjustment, and that what serves one group may damage another, which reopens the question of interests. Functional alternatives deny indispensability, since the same need may be met by different arrangements. Finally, a net balance of consequences replaces any simple verdict, and analysis is scaled down to the middle range.

Dominance and the Indian village studies

For roughly three decades after the Second World War this was the mainstream of sociology, framing studies of stratification, religion, deviance and the family. In India it arrived through social anthropology and shaped the village studies of the 1950s and 1960s. M. N. Srinivas in Rampura and S. C. Dube in Shamirpet described villages as functioning wholes in which caste specialisation, ritual hierarchy and the jajmani exchange of services fitted into a working order. The ethnographic detail was unmatched, but integrative assumptions made caste look like a division of labour sustained by consensus; later work attentive to class and to Dalit experience corrected the balance.

The critiques

Conflict theorists — Dahrendorf, Mills and Marxists more broadly — argued that consensus is manufactured rather than given, that what is called integration is often the settled dominance of one group, and that the perspective has no account of interests. Conservatism: explaining institutions through their usefulness tends to justify what exists, and Gouldner charged that the equilibrium bias served the postwar order. Teleology: to say an institution exists because it performs a function is to explain a cause by its effect, and functions identified after the fact cannot be falsified. Reification: societies are credited with needs that only actors possess. Interpretive critics objected that the improvised character of action disappears when actors become role-players executing system requirements, and feminist critics read the instrumental and expressive roles of Parsons's family as an arrangement of power dressed up as functional necessity. Change remains the standing weakness: a perspective built to explain persistence handles revolution and colonial rupture poorly.

For the UPSC answer

Set out the perspective as structure plus function joined by the organic analogy, then move through the lineage — Comte and Spencer, Durkheim's separation of cause from function, Malinowski and Radcliffe-Brown, Parsons, Merton — since examiners reward the genealogy. Give Merton the pivotal place: latent function, dysfunction and functional alternatives are the repairs that make functional analysis usable. Close with the critique of conservatism, teleology, reification and neglect of power and change, using the village studies of Srinivas and Dube to illustrate both the perspective's descriptive strength and its blindness to conflict.
