In 2012, both Kiplinger and Forbes ranked anthropology as the least valuable undergraduate major, unleashing a small wave of indignation as many outside the field rushed to defend the study of culture as ideal preparation for any life or career in an interconnected and globalized world. The response from professional anthropologists, confronted by both an existential challenge and public humiliation, was earnest but largely ineffective, for the voice of the discipline had been muted by a generation of self-absorption, tempered by a disregard for popular engagement that borders on contempt.

Ruth Benedict, acolyte of the great Franz Boas and in 1947 president of the American Anthropological Association (AAA), reputedly said that the very purpose of anthropology was to make the world safe for human differences.

Today, such activism seems as passé as a pith helmet. In the immediate aftermath of 9/11, the AAA met in Washington, D.C. Four thousand anthropologists were in the nation's capital in the wake of the biggest story of culture they or the country would ever encounter. The entire gathering earned but a mention in The Washington Post, a few lines in the gossip section essentially noting that the nutcases were back in town. It was hard to know who was more remiss, the government for failing to listen to the one profession that could have answered the question on everyone’s lips—Why do they hate us?—or the profession itself for failing to reach outside itself to bring its considerable insights to the attention of the nation.

Perhaps fittingly it took an outsider to remind anthropologists why anthropology matters. Charles King, professor of international affairs at Georgetown University, begins his remarkable book The Reinvention of Humanity by asking us to envision the world as it existed in the minds of our grandparents, perhaps your great-grandparents. Race, he notes, was accepted as a given, a biological fact, with lineages dividing white from Black reaching back through primordial time. Differences in customs and beliefs reflected differences in intelligence and destiny, with every culture finding its rung on an evolutionary ladder rising from the savage to the barbarian to the civilized of the Strand in London, with technological wizardry, the great achievement of the West, being the sole measure of progress and success.

Sexual and behavioral characteristics were presumed fixed. Whites were smart and industrious, Blacks physically strong but lazy, and some people were barely distinguishable from animals; as late as 1902 it was debated in parliament in Australia whether aborigines were human beings. Politics was the domain of men, charity work and the home the realm of women. Women’s suffrage only came in 1919. Immigrants were seen as a threat, even by those who had themselves only just managed to claw their way ashore. The poor were responsible for their own miseries, even as the British army reported that the height of officers recruited in 1914 was on average six inches taller than that of enlisted men, simply because of nutrition. As for the blind, deaf and dumb, the cripples, morons, Mongoloids, and the mad, they were best locked away, lobotomized and even killed to remove them from the gene pool.

The superiority of the white man was accepted with such assurance that the Oxford English Dictionary in 1911 had no entries for racism or colonialism. As recently as 1965, Carleton Coon completed a set of two books, The Origin of Races and The Living Races of Man, in which he advanced the theory that the political and technological dominance of Europeans was a natural consequence of their evolved genetic superiority. He even asserted that “racial intermixture can upset the genetic as well as the social equilibrium of a group.” Coon at the time of his retirement in 1963 was a respected professor and curator at the University of Pennsylvania. Interracial marriage remained illegal across much of the United States until 1967.

Today, not two generations on, it goes without saying that no educated person would share any of these bankrupt certitudes. By the same token, what we take for granted would be unimaginable to those who fiercely defended convictions that appear to the modern eye both transparently wrong and morally reprehensible. All of which raises a question. What was it that allowed our culture to go from zero to 60 in a generation, as women moved from the kitchen to the boardroom, people of color from the woodshed to the White House, gay men and women from the closet to the altar?

Political movements are built upon the possibility of change, possibilities brought into being by new ways of thinking. Before any of these struggles could flourish, something fundamental, some flash of insight, had to challenge and, in time, shatter the intellectual foundations that supported archaic beliefs as irrelevant to our lives today as the notions of 19th-century clergymen, certain that the earth was but 6,000 years old.

The catalyst, as Charles King reminds us, was the wisdom and scientific genius of Franz Boas and a small band of courageous scholars—Margaret Mead, Alfred Kroeber, Elsie Clews Parsons, Melville Herskovits, Edward Sapir, Robert Lowie, Ruth Benedict, Zora Neale Hurston and many others— contrarians all, who came into his orbit, destined to change the world. We live today in the social landscape of their dreams. If you find it normal, for example, that an Irish boy would have an Asian girlfriend, or that a Jewish friend might find solace in the Buddhist dharma, or that a person born into a male body could self-identify as a woman, then you are a child of anthropology.

If you recognize that marriage need not exclusively imply a man and a woman, that single mothers can be good mothers, and that two men or two women can raise good families as long as there is love in the home, it’s because you’ve embraced values and intuitions inconceivable to your great-grandparents. And if you believe that wisdom may be found in all spiritual traditions, that people in all places are always dancing with new possibilities for life, that one preserves jam but not culture, then you share a vision of compassion and inclusion that represents perhaps the most sublime revelation of our species, the scientific realization that all of humanity is one interconnected and undivided whole.

Widely acknowledged as the father of American cultural anthropology, Franz Boas was the first scholar to explore in a truly open and neutral manner how human social perceptions are formed, and how members of distinct societies become conditioned to see and interpret the world. What, he asked, was the nature of knowing? Who decided what was to be known? How do seemingly random beliefs and convictions converge into this thing called culture, a term that he was the first to promote as an organizing principle, a useful point of intellectual departure.

Far ahead of his time, Boas recognized that every distinct social community, every cluster of people distinguished by language or adaptive inclination, was a unique facet of the human legacy and its promise. Each was a product of its own history. None existed in an absolute sense; every culture was but a model of reality. We create our social realms, Boas would say, determine what we then define as being common sense, universal truths, the appropriate rules and codes of behavior. Beauty really does lie in the eye of the beholder. Manners don’t make the man; men and women invent the manners. Race and gender are cultural constructs, derived not from biology but born in the realm of ideas.

Critically, none of this implied an extreme relativism, as if every human behavior must be accepted simply because it exists. Boas never called for the elimination of judgment, only its suspension so that the very judgments we are ethically and morally obliged to make as human beings may be informed ones. Even as he graced the cover of Time magazine in 1936, a German Jew in exile from a homeland already dripping in blood, Boas railed against the cruel conceits and stupidity of scientific racism. Inspired by his time among the Inuit on Baffin Island, and later the Kwakwaka’wakw in the salmon forests of the Pacific Northwest, he informed all who would listen that the other peoples of the world were not failed attempts to be them, failed attempts to be modern. Every culture was a unique expression of the human imagination and heart. Each was a unique answer to a fundamental question: What does it mean to be human and alive? When asked that question, humanity responds in 7,000 different languages, voices that collectively comprise our repertoire for dealing with all the challenges that will confront us as a species.

Boas would not live to see his insights and intuitions confirmed by hard science, let alone define the zeitgeist of a new global culture. But, 80 years on, studies of the human genome have indeed revealed the genetic endowment of humanity to be a single continuum. Race truly is a fiction. We are all cut from the same genetic cloth, all descendants of common ancestors, including those who walked out of Africa some 65,000 years ago, embarking on a journey that over 40,000 years, a mere 2500 generations, carried the human spirit to every corner of the habitable world.

But here is the important idea. If we are all cut from the same fabric of life, then by definition we all share the same mental acuity, the same raw genius. Whether this intellectual potential is exercised through technological innovation, as has been the great achievement of the West, or through the untangling of complex threads of memory inherent in a myth, a priority of many other peoples in the world, is simply a matter of choice and orientation, adaptive insights and cultural emphasis. There is no hierarchy of progress in the history of culture, no evolutionary ladder to success. Boas and his students were right. The brilliance of scientific research, the revelations of modern genetics, has affirmed in an astonishing way both the unity of humanity and the essential wisdom of cultural relativism. Every culture really does have something to say; each deserves to be heard, just as none has a monopoly on the route to the divine.

As a scholar, Boas ranks with Einstein, Darwin and Freud as one of the four intellectual pillars of modernity. His core idea, distilled in the notion of cultural relativism, was a radical departure, as unique in its way as was Einstein’s theory of relativity in the discipline of physics. Everything Boas proposed ran against orthodoxy. It was a shattering of the European mind, the sociological equivalent of the splitting of the atom. And though his research took him to esoteric realms of myth and shamanism, symbolism and the spirit, he remained grounded in the politics of racial and economic justice, the promise and potential of social change. A tireless campaigner for human rights, Boas maintained always that anthropology as a science only made sense if it was practiced in the service of a higher tolerance. “It is possible,” wrote Thomas Gossett in his 1963 book Race: The History of an Idea in America, that “Boas did more to combat race prejudice than any other person in history."

Though remembered today as the giants of the discipline, Boas and his students in their time were dismissed from jobs because of their activism; denied promotion because of their beliefs; harassed by the FBI as the subversives they truly were; and attacked in the press simply for being different. And yet they stood their ground, and because they did, as Charles King writes, “anthropology came into its own on the front lines of the great moral battle of our time… [as it] anticipated and in good measure built the intellectual foundations for the seismic social changes of the last hundred years from women’s suffrage and civil rights to sexual revolution and marriage equality.”

Were Boas to be with us today, his voice would surely resound in the public square, the media, in all the halls of power. He would never sit back in silence as fully half the languages of the world hover on the brink of extinction, implying the loss within a single generation of half of humanity’s intellectual, ecological and spiritual legacy. To those who suggest that indigenous cultures are destined to fade away, he would reply that change and technology pose no threat to culture, but power does. Cultures under threat are neither fragile nor vestigial; in every instance, they are living dynamic peoples being driven out of existence by identifiable forces. If human beings are the agents of cultural loss, he would note, we can surely be facilitators of cultural survival.  

Anthropology matters because it allows us to look beneath the surface of things. The very existence of other ways of being, other ways of thinking, other visions of life itself, puts the lie to those in our own culture who say that we cannot change, as we know we must, the fundamental way in which we inhabit this planet. Anthropology is the antidote to nativism, the enemy of hate, a vaccine of understanding, tolerance and compassion that silences the rhetoric of demagogues, inoculating the world from the likes of the Proud Boys and Donald Trump. As the events of the last months have shown, the struggle long ago championed by Franz Boas is ongoing. Never has the voice of anthropology been more important.

But it must be spoken to be heard. With a million Uighurs in Chinese prison camps, the forests of the Penan in Sarawak laid waste, and the very homeland of the Inuit melting from beneath their lives, contemporary anthropologists must surely do better than indulging doctrinal grievance studies, seminars on intersectionality, the use of pronouns and other multiple expressions of woke orthodoxy if the discipline is to avoid the indictment of actually being the most worthless of undergraduate degrees.
