The term orthogenetic change was used by Indian sociologist D. P. Mukerji to describe change that arises from within the cultural and social traditions of a society, as opposed to heterogenetic change, which is externally induced (e.g., by colonialism or Westernization).
Thus:
Orthogenetic change = endogenous, internal evolution
Heterogenetic change = exogenous, externally influenced
In India, social change is rarely purely one or the other — rather, orthogenetic change operates through differentiation within traditional institutions, maintaining a sense of continuity even as transformations occur.
Orthogenetic Change through Differentiation
1. Meaning of Differentiation
Differentiation refers to the process by which social structures, roles, or institutions become more specialized and functionally distinct over time. It is a central mechanism of change in sociological theory — seen in Spencer’s evolutionary theory, Durkheim’s transition from mechanical to organic solidarity, and Parsons’ structural differentiation.
In India, differentiation within traditional institutions — caste, kinship, religion, and economy — has been the main pathway for internal or orthogenetic change.
2. Orthogenetic Differentiation in Indian Society — Examples
(a) Caste System
- The caste system has undergone functional differentiation without being completely dismantled.
- For instance, jati-based occupations have diversified — Brahmins now work as teachers, bureaucrats, and engineers rather than only priests.
- M. N. Srinivas’s concept of ‘Sanskritization’ also represents an orthogenetic process: lower castes adopt the rituals and lifestyles of higher castes to achieve upward mobility within the Hindu social framework, not outside it.
- This shows change from within tradition — not revolution, but evolutionary differentiation.
(b) Family and Kinship
- The Indian joint family is slowly differentiating into nuclear families due to industrialization, migration, and education, yet the ideological core of kinship solidarity remains strong.
- Rituals like shraddha and wedding alliances still preserve the sense of joint family identity — showing continuity within change.
(c) Religion and Reform Movements
- Reform movements such as Arya Samaj, Brahmo Samaj, and Bhakti movements exemplify orthogenetic change.
- They sought moral and spiritual regeneration from within Hinduism, not rejection of it.
- For instance, Swami Dayananda Saraswati called for “Back to the Vedas”, not Western secularism.
- This shows differentiation of religious ideology — more rational, ethical, and individual-centered — yet continuity with ancient roots.
(d) Village and Panchayat System
- The Panchayati Raj system (post-1952) is a modernized differentiation of the traditional village panchayat.
- The structural form changed — constitutional recognition, elections, inclusion of women and Scheduled Castes — but the ethos of community decision-making continues.
→ Hence, a perfect example of orthogenetic evolution through differentiation.
3. Continuities in Orthogenetic Processes
Yes, we observe strong continuities in the Indian orthogenetic process — the change remains organic, gradual, and culturally rooted.
| Traditional Institution | Old Function | New Function | Continuity |
|---|---|---|---|
| Caste | Ritual hierarchy | Socio-political identity (vote-bank, reservation) | Group solidarity, endogamy |
| Family | Economic + social unit | Emotional + symbolic unit | Kinship obligations persist |
| Religion | Ritualistic | Ethical–spiritual and identity-based | Central to cultural life |
| Village Panchayat | Customary justice | Local governance | Participatory ethos retained |
Thus, India’s modernization has been cultural modernization rather than structural rupture — a process Yogendra Singh called “modernization of tradition.”
4. Theoretical Interpretations
| Thinker | Concept | Relevance |
|---|---|---|
| D. P. Mukerji | Orthogenetic vs. heterogenetic change | Indian society changes from within its tradition |
| M. N. Srinivas | Sanskritization and Westernization | Dual process — internal and external change |
| Yogendra Singh | Modernization of tradition | Differentiation occurs within cultural continuity |
| Louis Dumont | Homo Hierarchicus | Despite differentiation, hierarchy remains the guiding principle |
| Parsons | Structural differentiation | Explains institutional specialization in modernization |
Hence, India’s social evolution is a hybrid: internally generated differentiation with adaptive continuity.
5. Illustrative Continuities in Modern India
- Caste politics: Differentiated from ritual hierarchy to political mobilization (e.g., Yadavs, Dalits, Jats) → internal transformation, not abolition.
- Education: Earlier pathshalas and gurukulas → modern schools → but moral-spiritual education remains valued.
- Economic life: Traditional merchant castes (e.g., Marwaris, Chettiars) adapt to global capitalism → continuity of community-based networks.
6. Critical Note
- Orthogenetic differentiation may preserve inequalities by adapting hierarchy to new contexts.
- E.g., caste endogamy and patriarchy persist even in urban, modern sectors.
- Thus, continuity sometimes means rearticulation of domination, not emancipation.
Conclusion
In a society like India, orthogenetic changes indeed take place through differentiation — that is, social transformation emerges from the internal reorganization of traditional institutions rather than through external imposition.
At the same time, these processes show remarkable continuity, reflecting India’s ability to integrate change within its civilizational framework.
As D. P. Mukerji emphasized, India’s modernization is neither imitation nor rupture but creative adaptation — a process where continuity and change coexist, driven by the differentiation of tradition itself.
