Introduction
Classical Evolutionism and Diffusionism emerged in 19th and early 20th-century anthropology as competing macro-theoretical frameworks to account for human cultural variability and cultural change. While both paradigms addressed the historical development and cross-cultural similarities of societies, they fundamentally diverged in their assumptions regarding human creativity, trajectories of progress, and investigative methods.
Core Differences Between Evolutionism and Diffusionism
Both classical paradigms sought to explain macro-cultural similarities but adopted antithetical premises regarding the driving forces of culture change.
- Mechanism of Change:
- Evolutionism: Cultural change is driven primarily by internal growth and independent invention (parallelism). It rests on the foundational assumption of the psychic unity of mankind, postulating that uniform human cognitive capabilities inevitably produce similar cultural inventions under similar environmental conditions.
- Diffusionism: Cultural change is driven by external borrowing and contact. Diffusionists presumed that human beings are fundamentally uninventive and that cultural traits originate in a few innovation centres before spreading outward across societies.
- Sequence and Trajectory:
- Evolutionism: Cultural progression follows a deterministic, unilinear sequence progressing through universal hierarchical stages, famously formulated as Savagery to Barbarism to Civilization.
- Diffusionism: Rejects predetermined universal evolutionary sequences. Cultural traits radiate unevenly and non-linearly across geographical spaces through trade, migration, and conquest.
- Methodological Orientation:
- Evolutionism: Employs the deductive Comparative Method, arranging ethnographic data gathered from varied contemporary societies into a reconstructed historical sequence from simple to complex ('armchair anthropology').
- Diffusionism: Uses an inductive, historical-geographical method involving trait mapping, spatial distribution analysis, and the reconstruction of historical migration routes.
- Prominent Schools and Proponents:
- Evolutionism: British school led by Edward Burnett Tylor and James George Frazer; American school led by Lewis Henry Morgan, emphasizing concepts like 'survivals' and evolutionary stages.
- Diffusionism: Comprises the British School (Pan-Egyptian Heliocentrism of G.E. Smith and W.J. Perry), the German-Austrian School (Kulturkreise or culture circles doctrine of Fritz Graebner and Wilhelm Schmidt), and the American School (Culture Area and Culture Complex concepts developed by Clark Wissler and A.L. Kroeber).
Conclusion
While both theoretical frameworks were critiqued for historical conjecturalism and macro-determinism, contemporary anthropological thought synthesizes their valid insights. Modern understandings of globalization recognize that cultural dynamics entail both local independent adaptations and rapid transnational cultural diffusion.
