In 1999, a young PhD candidate in philosophy named Nick Bostrom published an article in Mind entitled “The Doomsday Argument is Alive and Kicking.” The article asked whether probabilistic attempts to predict when the last human being would be born were reasonable. (They were, it argued.) The title, however, signaled something far more significant: the end of post–Cold War optimism. Human extinction was back on the menu.
In the years following the Mind article, Bostrom’s star would rise. He was instrumental in founding at Oxford the academic think tank Future of Humanity Institute, devoted to preventing human extinction. Seven years later, his work would help inspire the founding at Cambridge of a second such institute, the Centre for the Study of Existential Risk. By 2015, Bostrom had made Foreign Policy’s “Top 100 Global Thinkers” list for the second time.
X-risk preoccupations extend far beyond the ivory tower. Jaan Tallinn, formerly of Skype, co-founded both the CSER and the Future of Life Institute in Cambridge, Massachusetts, and has donated generously to the FHI and the Berkeley Existential Risk Initiative. The mercurial Elon Musk sits on the advisory board of both the CSER and the FLI and has bequeathed millions to each. The Open Philanthropy Project, a charitable organization run by Facebook co-founder Dustin Moskovitz, has pledged to donate over $15 million to the FHI. It is no exaggeration to say that billionaires are quietly bankrolling existential risk research.
A case in point: he tells us that the “discovery” of human extinction was the ultimate triumph of Enlightenment rationalism. Thanks to a series of intellectual breakthroughs — and growing awareness that the cosmos might be devoid of intelligent life — modern science and Enlightenment philosophy confronted the fact that human survival is not preordained. We alone can secure our future: “Remember, the human is a being whose vocation […] is to liberate itself from its own extinction,” he intones. Yet, while X-Risk represents an exhaustive catalog of reflections on our species’s potential demise — spanning centuries, academic disciplines, and national borders — Moynihan’s history also contains a glaring, dangerous, and obviously intentional omission: the word “eugenics” does not appear once in 424 pages.
This is no mere oversight. His book systematically glosses over the fact that human extinction was a hobbyhorse of the eugenics movement, and it has now reemerged as a fascination of the contemporary existential risk crowd, often rebranded as “bioenhancement,” “transhumanism,” and even “new eugenics.” Indeed, although he avoids the word “eugenics,” his desire to rehabilitate eugenic discourse is clear: “[T]he pathway to the future — and to maturity over extinction — is the path of bioenhancement,” Moynihan proclaims near the end of his book. He then writes: “To truly assume maturity, perhaps, is to realize that we must leave Earth and our evolutionary past behind.”
In the 19th-century Anglophone world, no single text did more to refashion thinking about human extinction than the publication of Darwin’s On the Origin of Species in 1859. It was often viewed as an “outrage” to humanity’s “naïve self-love” (as Freud famously described Darwin’s impact decades later). But an influential cross section of Darwin’s contemporaries and inheritors saw evolutionary science not as a scythe that cut humankind down to size but as heralding glorious possibilities for human supremacy. They accepted the assertion that human beings are precarious animals vulnerable to extinction, but they rejected the idea that the human species is not uniquely privileged among organic beings. After all, we are the only animal capable of being paranoid about our evolutionary future, and potentially able to safeguard it.
In 1923, J. B. S. Haldane wrote a short book, Daedalus; or, Science and the Future. The first installment in the English publisher Kegan Paul’s infamous “To-day and To-morrow” series, it imagines a future remade by eugenic enhancement. “Had it not been for ectogenesis, there can be little doubt that civilization would have collapsed […] owing to the greater fertility of the less desirable members of the population in almost all countries,” writes Haldane. The book ends with an unsettling prediction: “The scientific worker of the future will more and more resemble the lonely figure of Daedalus as he becomes conscious of his ghastly mission, and proud of it.” The following year, the prominent Oxford philosopher F. C. S. Schiller would pen the next “To-day and To-morrow” contribution. In Tantalus, or The Future of Man, he warns that humanity’s “future has always been precarious […] because it has always been uncertain whether [our species] would use its knowledge well or ill, to improve or to ruin itself.” Biological knowledge — politically mediated through eugenics — promised a means by which this improvement might be achieved and existential ruin avoided. Anthony Ludovici, a fellow British philosopher and translator of Nietzsche, would similarly maintain that the stakes of “eugenic mating” were nothing less than “the survival of human life in a desirable form.” He offered these insights in a 1926 book (part of the same series) on “woman’s future and future woman” in which he opined that birth control should ideally be replaced by “some kind of controlled and legalized infanticide.”
As the decade wound to a close, such pronouncements only grew more dire and disturbing. Charles John Bond, a doctor and euthanasia enthusiast, would deliver the 1928 Galton Lecture in which he proclaimed that the biologically feeble poor were akin to “parasitic cancer cells” that threatened humanity by out-reproducing the wealthy. Assuming that “civilized” temperament and fecundity were inversely related, he speculated that increasing the fertility of the elites “might prove to be the deciding factor in race survival in the future.” As for the lower classes? “We ought to welcome the extinction of the degenerate race,” Bond counseled.
In fleshing out this partial history of existential risk’s entanglement with eugenics, my aim is not to paint contemporary x-risk researchers as mustache-twirling villains. I had the pleasure of speaking on a panel with Moynihan a few years ago — he came across as thoughtful, modest, and unlikely to be engaged in a malicious conspiracy. Likewise, it seems a stretch to suggest that Nick Bostrom’s philosophy “contains all the ingredients necessary for a genocidal catastrophe,” as the philosopher Phil Torres recently claimed in a rather hyperbolic article for Current Affairs.
In the broadest terms, people like Moynihan, Bostrom, and even Musk are united by conviction that we — or, rather, they — have a profound moral imperative to prevent human extinction and provide a livable world for far-future human beings. These are laudable aims. Yet, we should also remember that many early eugenicists also had noble aspirations: Haldane was a staunch anti-imperialist who died an Indian citizen, and Julian Huxley was a vocal opponent of racialized eugenics who spoke vociferously against the Nazi program. Many of them viewed their work as part of the struggle against capitalistic inequality, and yet they also believed in the liberatory potential of eugenics. Any history that attempts to enlist them as Moynihan does in the fight against human extinction must reckon with this complicated legacy.
Here, it is again worth recalling Julian Huxley, who delivered a speech at Madison Square Garden not long after human shadows were transposed onto Hiroshima concrete. Speaking to an audience of some 18,000 assembled there for a “crisis meeting” on nuclear weapons, the biologist radiated optimism. In a marked departure from his earlier premonitions of dysgenic collapse, Huxley now opined that the species might yet be saved from existential peril by repurposing the split atom for the common good. A few hundred atomic bombs might usefully be dropped on the “polar regions,” Huxley cheerfully advised the crowd. He reasoned that the resulting ice melt would transform the Earth, leading to a warmer, more pleasant climate.
Tyler Harper is a literary scholar working at the intersection of environmental studies, philosophy, and the history of science. His current book project, provisionally entitled “The Paranoid Animal: Human Extinction Before the Bomb,” examines how British literary figures, scientists, and social theorists engaged with the concept of human extinction prior to the nuclear age.
