The Victory of an Idea Is Also Its Vulnerability

These four notes, read together, trace the complete lifecycle of a single idea — and reveal how the very machinery of its triumph becomes ammunition for its critics.

Degler documents the origin: Boas's substitution of culture for race spread with 'remarkable' speed across the social sciences. Duedahl shows the next phase, when diffusion became deliberate campaign. UNESCO didn't just reflect a scientific consensus; it manufactured one, convening 'carefully-chosen' panels, favoring social scientists over physical anthropologists, and bombarding national education systems with publications. By the time Diamond writes his one-sentence summary — differences among peoples come from environments, not biology — the idea has become common sense, the kind of thing a bestseller can assert without argument.

Derbyshire's note shows what happens at the end of this arc. His polemical move is precisely genealogical: he refuses to treat 'culturism' as a scientific finding and instead presents it as one theory among three, with a lineage (Bastian to Boas) and therefore a contingency. Meanwhile 'Biologism is just ordinary scientific method applied to humanity' — his own position gets no genealogy at all, as if it fell from the sky. The rhetorical asymmetry is the tell, but the underlying observation is uncomfortable because Duedahl's archival work partly supports it: the culture concept's global authority was engineered as much as earned, with panel composition and political urgency (Brown v. Board, apartheid) doing work that evidence alone did not.

The deeper insight is that ideas which win through institutional amplification inherit a specific fragility. An idea that spreads on evidence can be defended with evidence; an idea that spread partly through UNESCO statements and curated expert panels can always be re-described as ideology. Boas's intellectual descendants won so completely that their victory left a paper trail — and Degler and Duedahl's histories, written sympathetically, furnish the raw material for Derbyshire's hostile reading. Every successful idea eventually has to answer for how it succeeded.

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.

There are three theories of human nature enjoying widespread support at present. For convenience, I’ll tag each one of them with a single adjective. Religious. Our species Homo sapiens is the special creation of God, either as a one-off miracle or by God-guided evolution. Human nature is a mix of attributes, some natural ones arising from plain biology, some supernatural ones inserted by God. We are the Chosen Species. The God-given attributes are unique to our species. They are the same in all human populations, forming the foundation of our essential equality. Their existence is independent of our biological nature, even to the degree that they can continue to exist after our deaths. Being nonbiological, they don’t evolve, even if other features of the living world do, so that our evolution, if it ever took place, ended (except perhaps for some incidental biological features) when God decreed we have these supernatural attributes. These God-given attributes include the moral sense, which accesses transcendent truths—i.e., truths that do not dwell in the world of matter. God rules! Cultural. Our species arose, like all other species, from the ordinary processes of evolution. However, these processes ceased in the early history of the species, leaving us with a human nature uniform across all populations and unchanging over time, forming the foundation of our essential equality. This human nature has very little innate structure and is extremely plastic. By placing it in a suitable environment, or applying suitable pressures, the mind (and therefore the behavior, which issues from the mind) can be shaped in any way at all. “Human nature” does not really exist independent of the environment an individual happens to be in, especially that part of the environment made up of other human beings—“the culture.” Moral standards are arbitrary, and are taken in by the individual from the culture. Culture rules! Biological. Our species arose, like all other species, from the ordinary processes of evolution, which have continued to the present day. Human nature is a collection of characteristics all susceptible to biological explanation. Some characteristics of a person’s nature can be shaped to some degree by “cultural” (i.e., social or environmental) forces; some cannot. Human beings are a part of the living world, and nothing more. Our equality consists in being members of a single species; though our species, like any other with very wide distribution, exhibits regional differences. The characteristics of an individual human being are templated in his genome. They may be somewhat modified by womb events or life experiences; or they may need to be “instantiated” by postpartum environment. (An individual’s genome may, for example, predispose him to be eloquent or tongue-tied when using language; but which language he uses will depend on his childhood environment.) The repertoire of human behaviors, and of ideas, including moral ideas, about behavior, are innate, the result of evolutionary processes acting on our social lives across many generations. Biology rules! For convenience in what follows, I’ll label adherents of these three views with the more or less made-up words “Religionists,” “Culturists,” and “Biologians.” Each point of view has a history. Religionism emerges from core features of human thinking, as described by cognitive scientists like Pascal Boyer (Religion Explained, 2001), Scott Atran (In Gods We Trust, 2002), and Bruce Hood (Supersense, 2009). Culturism has roots in the tabula rasa (“blank slate”) theories of Aristotle and Locke. It was put into its modern form by German anthropologist Adolf Bastian (1826–1905). Bastian coined the phrase “the psychic unity of mankind.” His student Franz Boas brought these ideas to the United States, becoming the most influential American anthropologist of the early twentieth century. Biologism is just ordinary scientific method applied to humanity.

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