How the Culture Idea Traveled — and What Each Vehicle Changed

2026-07-24 · AI-generated insight

These notes trace a single idea — human difference is not biological — through three vehicles of diffusion, and each vehicle reshaped both its speed and its content.

Degler describes the first stage: Boas's culture concept "conquered his own field" and spread to neighboring disciplines with remarkable speed. Within academic circles, where the currency is argument and the audience is small and primed, a genuinely seminal idea can diffuse in years.

Duedahl's account of UNESCO is the sobering counterpoint. Even with an international institution deliberately amplifying essentially the same idea — expert statements, publications infiltrating school systems, testimony before the Supreme Court — turning it into something with "truly global appeal" took decades and repeatedly stalled. The obstacles weren't intellectual but logistical and political: translation costs, no non-Western scholars located, no control over national distribution channels, and urgency perceived only where segregation was most visible. The contrast is instructive: ideas conquer disciplines fast and publics slowly, because disciplines are networks of peers while publics are fragmented terrains that institutions must physically traverse.

But the Diamond note reveals something subtler: diffusion changed the idea itself. Boas's claim, per Degler, was that group differences are "the product of different histories" — an open-ended, contingent explanation that resists law-like prediction. Diamond's bestselling version keeps the anti-racist conclusion but swaps the mechanism: not different histories but "differences among peoples' environments." That's a determinism — geography as destiny — of exactly the kind Boas's culture concept was built to escape. It's arguably what made the idea popularizable: a single causal law travels better than an insistence on contingency. A reader can hold "geography determines fates" in one hand; "every people's trajectory is a unique historical accumulation" doesn't fit in a hand at all.

So the price of mass diffusion may have been re-determinization. UNESCO struggled to spread the nuanced version; Diamond succeeded by flattening it. The pattern suggests a general trade-off: an idea's reach and its fidelity to contingency pull in opposite directions.

Woven from these notes

Until the 1890s Boas used the term as his fellow anthropologists did: as another word for civilization or “high culture.” Franz Boas’s exposition of the concept of culture as an alternative to race in accounting for differences among human groups was a genuine seminal contribution. The idea not only conquered his own field of anthropolgy but spread as well to other social science disciplines. The diffusion was remarkably rapid. Again and again in the early years of the new century American social scientists outside of anthropology testified to the influence of his writings on their conception of human nature and the place of biology or race within it.

In 1997, Akira Iriye characterized UNESCO as a hub for cultural internationalism in the wake of World War II, and recent research has confirmed the impression of the organization as an excellent prism reflecting ways of thinking that became popular on a global scale and that it has sometimes even served as the initiating and powerful promotor of concepts that became popular and widely used, such as ‘world heritage’ and ‘global citizenship’. In this article, I have sought to demonstrate another example of the proactive role of UNESCO. The articles has focused on the organization’sefforts to launch a program supposed to combat racial inequality, which is not mentioned by Iriye, but which according to other scholars, placed the organization in the middle of a dispute in international scientific circles over the correct definition of the concept of race. Thus, in the article I have combined Iriye’s focus on the importance of cultural internationalism for global peace-making and UNESCO’s important role with the studies of the organization’s work within the field of race as well as my archival findings in order to draw a conclusion as to whether its showdown with the race concept had a global impact. What we see is that, from 1950 to 1967, UNESCO managed to issue four statements of race formulated by some of the world’s leading yet simultaneously carefully-chosen scientists, most Western and all stressing human equality. The organization’s preference for social scientists rather than physical anthropologists at the same time made the organization a centre of a dispute organized around the question of whether the natural or social sciences should take precedence in determining the origins of human difference, of social division, and the attribution of value. Outside of UNESCO headquarters, the statements for the same reasons caused severe criticism in a time still characterized by European colonialism, American segregation, and South African apartheid policies. Only on one occasion, in 1964, was a researcher chosen despite being overtly critical towards the organization’s work and only in 1967 could the panel of scientists be characterized as truly global in its scope and composition. UNESCO also issued a series of publications that were able to infiltrate national educational systems and which represented a steady bombardment of publications that at least physical anthropologists had to deal with. Critique of their content nonetheless only added to public awareness of the organization’s work. As the cases on segregation reached the U.S. Supreme Court, the outcome of UNESCO’s race program would also play a role. This article shows that experts affiliated with the organization were on several occasions brought in as expert witnesses and that the statements on race highlighted as the newest available research, paving the 16 P. DUEDAHL way towards the eradication of state-approved segregation in the U.S., whereas South Africa chose to withdraw from UNESCO. In sum, the statements and the authority with which the experts spoke had an impact and came to play a major part in imposing the new post-war view of man in several countries. However, it is only after 1960 that UNESCO’s cultural internationalism within the field of race can be said to focus on racism as a problem that had to be solved on a global scale. The main reasons for this was that discussions within academic circles ahead of UNESCO’s race efforts had mainly been going on among Western scholars, that UNESCO failed to locate non-Western scholars, and that dealing with racism was perceived as most urgent in the U.S. and South Africa. Also the expensiveness of translating UNESCO’s findings into all languages, the difficulties of promoting the content in a way that would have an impact on a larger group of people, and the lack of control over the many national environments that received and were supposed to distribute news from UNESCO made a difference. Only after a range of anti-Semitic incidents, the demands of a number of new Asian and African member states, and pressure from the UN, did the initiative gradually change. Altogether, it proved to be more difficult and to take a considerably longer time than initially imagined by UNESCO to turn a few scholar’s idea of race into one with a truly global appeal and impact.

History followed different courses for different peoples because of differences among peoples’ environments, not because of biological differences among peoples themselves.

Boas’s rejection of the traditional view was truly radical; it simply denied the existence of any significant innate differences between savage, colored people and civilized, white people. The differences in physical appearance, in short, did not lead to any significant difference in mental or social function. That there were observable social differences was undeniable, but the explanation for those differences. Boas maintained, was that they were the product of different histories, not different biological experiences.
