The Death of Truth. Michiko Kakutani

lockstep over knowledge is on display throughout the administration. Unqualified judges and agency heads were appointed because of cronyism, political connections, or a determination to undercut agencies that stood in the way of Trump’s massive deregulatory plans benefiting the fossil fuel industry and wealthy corporate donors. Rick Perry, who was famous for wanting to abolish the Department of Energy, was named to head it, presiding over cutbacks to renewable energy programs; and the new EPA head, Scott Pruitt, who had repeatedly sued the Environmental Protection Agency over the years, swiftly began dismantling and slow walking legislation designed to protect the environment.

      The public—which opposed the GOP tax bill and worried that its health care would be taken away—was high-handedly ignored when its views failed to accord with Trump administration objectives or those of the Republican Congress. And when experts in a given field—like climate change, fiscal policy, or national security—raised inconvenient questions, they were sidelined, or worse. This, for instance, is what happened to the Congressional Budget Office (created decades ago as an independent, nonpartisan provider of cost estimates for legislation) when it reported that a proposed GOP health-care bill would leave millions more uninsured. Republicans began attacking the agency—not just its report, but its very existence. Trump’s director of the Office of Management and Budget, Mick Mulvaney, asked whether the CBO’s time had “come and gone,” and other Republicans proposed slashing its budget and cutting its staff of 235 by 89 employees.

      For that matter, the normal machinery of policy making—and the normal process of analysis and review—were routinely circumvented by the Trump administration, which violated such norms with knee-jerk predictability. Many moves were the irrational result of a kind of reverse engineering: deciding on an outcome the White House or the Republican Congress wanted, then trying to come up with rationales or selling points afterward. This was the very opposite of the scientific method, whereby data is systematically gathered and assessed to formulate and test hypotheses—a method the administration clearly had contempt for, given its orders to CDC analysts to avoid using the terms “science-based” and “evidence-based.” And it was a reminder that in Orwell’s dystopia in 1984 there is no word for “science,” because “the empirical method of thought, on which all the scientific achievements of the past were founded,” represents an objective reality that threatens the power of Big Brother to determine what truth is.

      In addition to announcing that it was withdrawing from the Paris climate accord (after Syria signed on, the United States was left as the lone country repudiating the global agreement), the Trump administration vowed to terminate President Obama’s Clean Power Plan and reverse a ban on offshore oil and gas drilling. Scientists were dismissed from government advisory boards, and plans were made to cut funding for an array of research programs in such fields as biomedicine, environmental science, engineering, and data analysis. The EPA alone was facing proposed cuts from the White House of $2.5 billion from its annual budget—a reduction of more than 23 percent.

      IN APRIL 2017, the March for Science, organized in Washington to protest the Trump administration’s antiscience policies, grew into more than four hundred marches in more than thirty-five nations, participants marching out of solidarity with colleagues in the United States and also out of concern for the status of science and reason in their own countries. Decisions made by the U.S. government about climate change and other global problems, after all, have a domino effect around the world—affecting joint enterprises and collaborative research, as well as efforts to find international solutions to crises affecting the planet.

      British scientists worry about how Brexit will affect universities and research institutions in the U.K. and the ability of British students to study in Europe. Scientists in countries from Australia to Germany to Mexico worry about the spread of attitudes devaluing science, evidence, and peer review. And doctors in Latin America and Africa worry that fake news about Zika and Ebola are spreading misinformation and fear.

      Mike MacFerrin, a graduate student in glaciology working in Kangerlussuaq, a town of five hundred in Greenland, told Science magazine that the residents there had practical reasons to worry about climate change because runoff from the ice sheet had partially washed out a local bridge. “I liken the attacks on science to turning off the headlights,” he said. “We’re driving fast and people don’t want to see what’s coming up. Scientists—we’re the headlights.”

      ONE OF THE most harrowing accounts of just how quickly “the rule of raison”—faith in science, humanism, progress, and liberty—can give way to “its very opposite, terror and mass emotion,” was laid out by the Austrian writer Stefan Zweig in his 1942 memoir, The World of Yesterday. Zweig witnessed two globe-shaking calamities in his life—World War I, followed by a brief respite, and then the cataclysmic rise of Hitler and descent into World War II. His memoir is an act of bearing witness to how Europe tore itself apart suicidally twice within decades—the story of the terrible “defeat of reason” and “the wildest triumph of brutality,” and a lesson, he hoped, for future generations.

      Zweig wrote about growing up in a place and time when the miracles of science—the conquest of diseases, “the transmission of the human word in a second around the globe”—made progress seem inevitable, and even dire problems like poverty “no longer seemed insurmountable.” An optimism (which may remind some readers of the hopes that surged through the Western world after the fall of the Berlin Wall in 1989) informed his father’s generation, Zweig recalled: “They honestly believed that the divergencies and the boundaries between nations and sects would gradually melt away into a common humanity and that peace and security, the highest of treasures, would be shared by all mankind.”

      When he was young, Zweig and his friends spent hours hanging out at coffeehouses, talking about art and personal concerns: “We had a passion to be the first to discover the latest, the newest, the most extravagant, the unusual.” There was a sense of security in those years for the upper and middle classes: “One’s house was insured against fire and theft, one’s field against hail and storm, one’s person against accident and sickness.”

      People were slow to recognize the danger Hitler represented. “The few among writers who had taken the trouble to read Hitler’s book,” Zweig writes, “ridiculed the bombast of his stilted prose instead of occupying themselves with his program.” Newspapers reassured readers that the Nazi movement would “collapse in no time.” And many assumed that if “an anti-semitic agitator” actually did become chancellor, he “would as a matter of course throw off such vulgarities.”

      Ominous signs were piling up. Groups of menacing young men near the German border “preached their gospel to the accompaniment of threats that whoever did not join promptly, would have to pay for it later.” And “the underground cracks and crevices between the classes and races, which the age of conciliation had so laboriously patched up,” were breaking open again and soon “widened into abysses and chasms.”

      But the Nazis were careful, Zweig remembers, not to disclose the full extent of their aims right away. “They practiced their method carefully: only a small dose to begin with, then a brief pause. Only a single pill at a time and then a moment of waiting to observe the effect of its strength”—to see whether the public and the “world conscience would still digest this dose.”

      And because they were reluctant to abandon their accustomed lives, their daily routines and habits, Zweig wrote, people did not want to believe how rapidly their freedoms were being stolen. People asked what Germany’s new leader could possibly “put through by force in a State where law was securely anchored, where the majority in parliament was against him, and where every citizen believed his liberty and equal rights secured by the solemnly affirmed constitution”—this eruption of madness, they told themselves, “could not last in the twentieth century.”
