If you believe that climate change is a boutique issue prioritized only by out-of-touch liberal elites, as one poll found, then this bill, should it pass, represents a political achievement of astonishing magnitude: the triumph of a moral crusade against long odds.

if you believe there is quite a lot of public support for climate action, as other polls suggest — then this bill marks the success of outsider activists in holding establishment forces to account, both to their own rhetoric and to the demands of their voters.

whatever your read of public sentiment, what is most striking about the news this week is not just that there is now some climate action on the table but also how fast the landscape for climate policy has changed, shifting all of our standards for success and failure along with it

The bill may well prove inadequate, even if it passes. It also represents a generational achievement — achieved, from the point of view of activists, in a lot less time than a full generation.

Technological progress has driven the cost of renewable energy down so quickly, it should now seem irresistible to anyone making long-term policy plans or public investments. There has been rapid policy innovation among centrists and policy wonks, too, dramatically expanding the climate tool kit beyond carbon taxes and cap-and-trade systems to what has been called a whole-of-government approach to decarbonizing.

To trust the math of its architects, this deal between Manchin and the Senate majority leader, Chuck Schumer, splits the difference — the United States won’t be leading the pack on decarbonization, but it probably won’t be seen by the rest of the world as a laughingstock or climate criminal, either.

None of this is exclusively the work of the climate left

The present-day climate left was effectively born, in the United States, with the November 2018 Sunrise Movement sit-in. At the time, hardly anyone on the planet had heard of Greta Thunberg, who had just begun striking outside Swedish Parliament — a lonely, socially awkward 15-year-old holding up a single sign. Not four years later, her existential rhetoric is routinely echoed by presidents and prime ministers and C.E.O.s and secretaries general, and more than 80 percent of the world’s economic activity and emissions are now, theoretically, governed by net-zero pledges pointing the way to a carbon-neutral future in just decades.

as the political scientist Matto Mildenberger has pointed out, the legislation hadn’t failed at the ballot box; it had stalled on Manchin’s desk

He also pointed to research showing climate is driving the voting behavior of Democrats much more than it is driving Republicans into opposition and that most polling shows high levels of baseline concern about warming and climate policy all across the country. (It is perhaps notable that as the Democrats were hashing out a series of possible compromises, there wasn’t much noise about any of them from Republicans, who appeared to prefer to make hay about inflation, pandemic policy and critical race theory.)

It is hard not to talk about warming without evoking any fear, but the president was famous, on the campaign trail and in office, for saying, “When I think ‘climate change,’ I think ‘jobs.’”

He focused on green growth and the opportunities and benefits of a rapid transition.

In the primaries, Sunrise gave Biden an F for his climate plan, but after he sewed up the nomination, its co-founder Varshini Prakash joined his policy task force to help write his climate plan. As the plan evolved and shrank over time, there were squeaks and complaints here and there but nothing like a concerted, oppositional movement to punish the White House for its accommodating approach to political realities.

over the past 18 months, since the inauguration, whenever activists chose to protest, they were almost always protesting not the inadequacy of proposed legislation but the worrying possibility of no legislation at all

When they showed up at Manchin’s yacht, they were there to tell him not that they didn’t want his support but that they needed him to act. They didn’t urge Biden to throw the baby out with the bathwater; they were urging him not to.

When, last week, they thought they’d lost, Democratic congressional staff members staged an unprecedented sit-in at Schumer’s office, hoping to pressure the Senate majority leader back into negotiations with Manchin. And what did they say? They didn’t say, “We have eight years to save the earth.” They didn’t say, “The blood of the future is on your hands.” What their protest sign said was “Keep negotiating, Chuck.” As far as I can tell, this was code for “Give Joe more.”

They got their wish. And as a result, we got a bill. That’s not naïveté but the opposite.

The deal, if it holds, is very big, several times as large as anything on climate the United States passed into law before. The architects and supporters of the $369 billion in climate and clean-energy provisions in Joe Manchin’s Inflation Reduction Act of 2022, announced Wednesday, are already calculating that it could reduce American carbon emissions by 40 percent, compared with 2005 levels, by 2030. That’s close enough to President Biden’s pledge of 50 percent that exhausted advocates seem prepared to count it as a victory

My high level of vaccine antibodies probably explains my success more than my behavior. I make some effort to avoid Covid, but have been far from perfect. And I’ve been potentially exposed at least twice: Once last December, when someone at a small holiday gathering I’d attended developed symptoms the next day, and more recently, when I shared a large indoor space with two people who later tested positive. But according to my lab work, I’ve never had even a silent infection.

But one piece of advice almost no one is giving? Be lucky. Pediatrician Neil Stone says that there’s no “secret” for staying Covid-19 free because there’s just too much luck involved.

As for me, I have some data that can, to an extent, quantify and explain my own good luck in avoiding Covid so far. I’m participating in a study on immunity which allowed me to learn that my blood still carries loads of antibodies induced by my vaccine and December booster shot, and no signs of any prior infection. Not everyone’s antibodies wane at the same rate, and in some people, the antibodies don’t wane much at all. (At some point it should become routine to collect this information to help people decide whether to get additional booster shots.)

It’s possible I was protected by my high antibodies, or that some quirk of air flow meant I never breathed in enough virus to get sick. Or perhaps I benefited from a different form of luck. There’s another facet to immunity called the innate immune system, which acts as a first line of defense and sometimes knocks out a virus or other pathogen before it replicates enough to elicit the production of antibodies. Good innate immunity might help explain something many of us have experienced — not getting a cold or flu even when sleeping in the same bed with the sick person through the whole illness.

Stress, diet, general health and even sunlight might all affect innate immunity. So could other factors. There’s so much we still don’t know about the immune system. And that’s one reason we talk about “luck.”

understanding how the luck works could help other people avoid Covid, whether for the first time or for the second or third time. Taking a closer look at what passed for luck helped researchers like Gary Taubes discover that public health had obesity all wrong, and the standard high carb/low fat diets were causing people to gain weight.

it is also the continuation of a remarkably consistent German attitude toward Europe and the world since 1945. Think about how different the world would look if we did not have, at the center of Europe, its most powerful nation — the country that is the largest net contributor to the E.U. — totally committed to democratic and liberal values and willing to make sacrifices for them. Germany today is the rock on which a new Europe is being built.

the sacrifices are real and deep. Natural gas prices are up tenfold in Europe compared to last year. The price of electricity for 2023 is more than 15 times higher than it has been in recent years, by one estimate. Vladimir Putin is ramping up the pressure by slowing and even stopping gas exports to Germany

But Germany has not given in. Confronted with these massive challenges, it has patiently sought to diversify away from a dependence on Russia, investing even more in green technology, buying liquefied natural gas, reopening coal-fired plants and even debating whether to keep its last three nuclear power plants running longer than planned.

The European Union has suggested a 15 percent reduction in the consumption of natural gas this winter. Germany is trying to achieve a 20 percent cut just to be safe. German industry is being resourceful about energy efficiency, and companies are even thinking about sharing resources with competitors, all to get through the crisis.

Merkel herself was seen in similar ways when she came to power. Over time she developed the skills and stature to gain respect from all quarters. She might have erred in trying to develop too conciliatory a relationship with Moscow

but when Russia invaded Ukraine in 2014, she was at the forefront in condemning it and persuading Europe to impose an ambitious program of sanctions. She also led the world in responding to the Syrian refugee crisis, reassuring her country by declaring, “We can do this.” As of mid-2021, Germany hosts more than 1.2 million refugees, half of whom are from Syria. In fact, Germany has managed this stunning act of integration with minimal problems.

We always underestimate modern-day Germany and its leadership. The federal republic has had a remarkable run of leaders in the post-World War II era, from its first chancellor, Konrad Adenauer, to Willy Brandt to Helmut Schmidt to Merkel — and now, let’s hope, to Scholz. Can any other country compare over the past seven decades?

In 1945, no one would have predicted that Germany would develop as it has. It came out of the war utterly destroyed, its cities flattened, its population starving. Around 12 million ethnic Germans who had been expelled from other countries poured into Germany. Above all, postwar Germany was scarred by the gruesome legacy of Adolf Hitler and the Holocaust. But the country found a way to overcome its past, to become, in Henry Kissinger’s words, “a normal country … with an abnormal memory.” And that much larger Zeitenwende is one of the great good news stories of our times.

The oldest of the books of the Hebrew Bible date to roughly 3,000 years ago; the pyramids of Egypt go back about 5,000 years. These were not prehumans or near relatives. They were like us: complex, organized, alive to meaning and living at a time beyond reckoning.

Ruth Tringham of the University of California, Berkeley, who has devoted years to humanizing the remnants of this city of the dim past by focusing on one skeleton, of a woman she has dubbed Dido. Dido replastered her walls regularly, kept her home swept clean, covered the floor in reed mats and decorated the place with art: clay figures of animals and stylized human females. In other words: much like us.

Catalhoyuk was founded by pioneers of urban living. “When the earliest construction began,” Newitz writes, “many people coming to live at Catalhoyuk were only a generation or two removed from nomadism.” It was brand-new, this fixed settlement thing, but it proved remarkably successful. By the time Dido was born, the city was about 600 years old

A thousand years ago, meanwhile, East St. Louis, Ill., was the site of an urban sanctuary that archaeologists today call Cahokia. With a population of 30,000, it was larger than Paris was at the time. Like Paris, with its Eiffel Tower and Notre-Dame, it had distinguishing physical landmarks in the form of black earthen pyramids. It sprawled across both sides of the Mississippi River, beckoning visitors from all over the present-day Southern United States.

Cahokia seems to have been a place of spiritual pilgrimage, which drew diverse groups of Native American peoples, who spoke different languages and worshiped in various ways but came to share a reverence for this city and its ceremonial customs, which included human sacrifice. Its multiethnic, year-round population apparently serviced the religious pilgrims and, in the off-season, went about their own affairs.

Cahokia died not as a result of sudden catastrophe, like Pompeii, but seemingly because it lost its spiritual significance over time. Its people didn’t perish. The pilgrims just stopped coming; the local residents merged with other tribes. There is linguistic and other evidence that the Sioux are their descendants.

Newitz devotes space to debunking the popular notion that civilizations of the past “collapse” and become “lost,” pointing instead to indications of gradual change.

The operative lesson from the past, at least from this curated offering of former metropolises, seems to be that human culture is a plastic thing. Rather than lamenting the fragility of our current urban structures, we might do better figuring out how to bend and shape society for the future.

the effect of reading “Four Lost Cities” was more meditative. This is a long, long, long ride we are on. Much is beyond our control. Humanity trundles on.

A culture that separated intellect from integrity would stop granting undue moral mystique to graduates of elite colleges.

It would stop implicitly deriding occupations that are essential for our collective functioning but don’t require an extensive education.

such a society could better recognize that there are different forms of intelligence beyond book learning and test taking—from sound judgment to emotional awareness to practical handiness—and cultivate those attributes in our children and leaders.

This makes it especially useful in classrooms, where it can help students understand different perspectives and imagine themselves in distant situations

Once maligned as lowbrow, the genre has gained popularity over the past two decades. In 2009, Jay Parini hypothesized one reason for this: “In our high-velocity, high-volume world, the present can seem just too bright, too close. We need the filter of memory to pull reality into focus.”

the Cromwell of Mantel’s creation begins to “double” Mantel by the end of the series. He spends much of the trilogy’s final book looking at himself “with a novelist’s wonderment at a character who defies understanding.” Mantel’s resurrected version of the man, unlike the real Cromwell, seems to know that he’s a character in a narrative—and the effect is thrilling.

Thanks to social-science research, we now know that children’s life chances are profoundly affected by their context—not only income and family circumstances but also their community—more so than by their genetic profile or the medical care they receive.

With this in mind, we created what we call the Index of Deep Disadvantage, which reflects two traditional measures of income (the poverty rate and the “deep poverty rate,” meaning those with incomes below half the poverty line), two markers of health (birth weight and life expectancy), and the rate of social mobility for children who grow up in low-income families. We used this index to rank the roughly 3,100 counties in the United States along with the 500 most populous cities.

Immediately, the rankings revealed a stark geographical pattern.

the most disadvantaged places on our index were primarily rural

Though some of these were majority white, most were majority Black or Hispanic.

these places resembled, well, colonies—internal colonies within the U.S.

Considerable poverty exists in Chicago, Los Angeles, and New York. But in our apples-to-apples comparison, none of those cities ranked among even the 600 most disadvantaged places in the nation

The only cities on that list were a relatively small number of industrial municipalities such as Cleveland, Detroit, and Rochester.

Those living in the 200 most disadvantaged places on our index were just as likely to have major difficulties paying for housing as those in America’s 500 largest cities.

The places that our index identified as the 200 most disadvantaged are concentrated in three regions—Appalachia, South Texas, and the southern Cotton Belt.

hese places share a history of intensive resource extraction and human exploitation not seen to the same degree elsewhere in the United States

In each place, this economic pattern emerged (or, in the case of the Cotton Belt, fully flourished) in the late 19th or early 20th century. In each place, one industry came to dominate the economy, a pattern that held, broadly, until the 1960s, when King Cotton, King Tobacco, King Coal, and South Texas agriculture, would bow to the twin forces of automation and global competition.

many places with large Native American populations ranked among the most disadvantaged in the nation

While visiting many of the nation’s most disadvantaged places, we set out to build on this work through historical research, ethnographic observations, and in-depth interviews.

For generations, the appearance of towns in South Texas followed a pattern of social hierarchy: sturdy wood-frame houses, paved streets, and enclosed sewers in the white neighborhoods; shacks, dirt roads, and privies in the Mexican parts of town. Forced to migrate to find work during the off-season, generations of Mexican American children lost their right to a decent education. Even today, adult-illiteracy rates in these places are among the highest in the nation.

in Leflore County, Mississippi, for example, Black residents told us that violence was the No. 1 problem they face. The rate of death due to interpersonal violence there was nearly four times the national average, and well above that of Cook County, Illinois, home to Chicago

Throughout these regions, we saw the same themes emerge again and again—unequal schooling, the collapse of social infrastructure, violence, entrenched public corruption, and structural racism embedded in government programs.

Overall, poverty rates in these places are very low, babies are born healthy, people live to a ripe old age, and a low-income child usually has a similar chance of making it into the middle class as any other kid.

er they were forcibly relocated onto land mostly inhospitable to human habit

hey have enjoyed the lowest rates of violent crime, income inequality, and public corruption in the nation. These counties are unusually rich in social capital: Residents are connected to one another through volunteerism, membership in civic organizations, and participation in other community activities.

Counties that rank among those of greatest advantage began as agricultural communities with modestly sized farms, many originally secured through the 1862 Homestead Act that made landownership widely available. Many of these places have built on this history of broad-based wealth by making significant investments in schools, which has contributed to high graduation and college enrollment rates over generations.

One cannot fully understand the benefits enjoyed in America’s most advantaged places without considering the historic (and ongoing) exploitation of migrant labor that has gone on in them, mostly drawn from the U.S. border regions.

these communities have been more successful than most in preventing poverty, promoting health, and ensuring a level playing field for their children.

The upper Midwest is also overwhelmingly white. When we examined the relationship between whiteness and rank on the index, we found that a higher percentage of white residents is a significant predictor of a place’s rank, which is not at all surprising when one considers that the good schools and the good jobs have long been bestowed liberally on whites while being denied to Hispanic and Black Americans.

What makes the communities that are most advantaged unique is their histories as places of broad-based wealth. How different would conditions be in other parts of the country had they followed a similar, equitable course?

The lesson is that people seem to thrive—not always in high salaries but in health and life chances—when inequality is low; when landownership is widespread; when social connection is high; and when corruption and violence are rare.

The social leveling that is characteristic of communities in the upper Midwest is more than just a quaint cultural feature. It is the foundation of a community’s well-being. Until these regions’ virtues are shared nationwide, poverty and disadvantage will continue to haunt America.

Biden’s approval ratings are stubbornly low. In a recent ABC poll, only 30 percent of voters approve of his handling of the economy and only 23 percent approve of his handling of immigration at the southern border. Roughly three-quarters of American voters say that Biden, at 80, is too old to seek a second term. There have been a string of polls showing that large majorities in his own party don’t want him to run again. In one survey from 2022, an astounding 94 percent of Democrats under 30 said they wanted a different nominee.

I thought Biden’s favorability ratings would climb as economic growth has remained relatively strong and as inflation has come down. But it just hasn’t happened.

don’t find this passive fatalism compelling. The party’s elected officials are basically urging rank-and-file Democrats not to be anxious about a situation that is genuinely anxiety-inducing. Last month Gov. Phil Murphy of New Jersey told The Times, “This is only a matter of time until the broad party, and broadly speaking, Americans, converge with the opinions of folks like myself.” Really? Surely if there’s a lesson we should have learned from the last decade, it’s that we should all be listening harder to what the electorate is trying to say.

The Republicans who portray him as a doddering old man based on highly selective YouTube clips are wrong. In my interviews with him, he’s like a pitcher who used to throw 94 miles an hour who now throws 87. He is clearly still an effective pitcher.

People who work with him allow that he does tire more easily, but they say that he is very much the dynamic force driving this administration

In fact, I’ve noticed some improvements in his communication style as he’s aged. He used to try to cram every fact in the known universe into every answer; now he’s more disciplined. When he’s describing some national problem, he is more crisp and focused than he used to be, clearer on what is the essential point here — more confidence-inspiring, not less.

What about four or five years from now, at the end of a second term? Will he still be competent enough to lead? Biden is fit, does not smoke or drink alcohol, exercises frequently and has no serious health conditions, according to the White House

A study in The Journal on Active Aging of Biden’s and Trump’s health records from before the 2020 elections found that both men could qualify as “super-agers” — the demographic that maintains physical and mental functioning beyond age 80.

if the president I see in interviews and at speeches is out campaigning next year against an overweight man roughly his own age, then my guess is that public anxieties on this front will diminish.

To me, age isn’t Biden’s key weakness. Inflation is. I agree with what Michael Tomasky wrote in The New Republic: Biden’s domestic legislative accomplishments are as impressive as any other president’s in my adult life. Exactly as he should have, he has directed huge amounts of resources to the people and the places that have been left behind by the global economy. By one Treasury Department estimate, more than 80 percent of the investments sparked by the Inflation Reduction Act are going to counties with below-average college graduation rates and nearly 90 percent are being made in counties with below-average wages. That was the medicine a riven country needed.

it is also true that Biden’s team overlearned the lessons of the Obama years. If Barack Obama didn’t stimulate the economy enough during the Great Recession, Biden stimulated it too much, contributing to inflation and the sticker shock people are feeling.

Anger about inflation is ripping across the world, and has no doubt helped lower the approval ratings of leaders left, right and center. Biden’s 40 percent approval rating may look bad, but in Canada, Justin Trudeau’s approval rating is 36; in Germany Olaf Scholz is at 29; in Britain Rishi Sunak is at 28; in France Emmanuel Macron is at 23; and in Japan Fumio Kishida is also at 23. This is a global phenomenon

“Inflation is the reason Biden could not deliver on his core promise to return the country to normal and the main reason his poll numbers are bad.”

voters are looking back and retroactively elevating their opinion of Trump’s presidency. When he left office only 38 percent of Americans approved of his performance as president. Today, 48 percent do, his high-water mark.

Bitterness, cynicism and distrust pervade the body politic. People perceive reality through negative lenses, seeing everything as much worse than it is. At 3.8 percent, America’s unemployment rate is objectively low, but 57 percent of voters say that the unemployment rate is “not so good” or “poor.”

The nation’s bitter state of mind is a self-perpetuating negativity machine. Younger people feel dismissed; the older generations are hogging power. Faith in major institutions is nearing record lows. The country is hungry for some kind of change but is unclear about what that might look like. As the incumbent, Biden will be tasked with trying to tell a good news story of American revival, which is just a tough story to sell in this environment. And Biden is not out there selling it convincingly.

The bracing reality is that Trump’s cynicism and fury match the national mood more than Biden’s faithful optimism.

“They seem hell bent on nominating the one Democrat who would lose to Donald Trump,” Karl Rove told me recently. “They’ve got a lot of talent on their side, let’s not kid ourselves,” he continued, pointing to younger Democrats like Gretchen Whitmer, Mitch Landrieu, Gavin Newsom and Cory Booker.

A lot of the dump-Biden conversations are based on a false premise: that the Democratic Party brand and agenda are somehow strong and popular enough that any number of younger candidates could win the White House in 2024, and that if Biden were just to retire, all sorts of obstacles and troubles would go with him.

But Biden is not the sole or even primary problem here. To the extent that these things are separable, it’s the Democratic Party as a whole that’s ailing. The generic congressional ballot is a broad measure of the strength of the congressional party. Democrats are now behind. According to a Morning Consult poll, Americans rate the Democratic Party as a whole as the more ideologically extreme party by a nine-point margin.

When pollsters ask which party is best positioned to address your concerns, here too, Democrats are trailing. In a recent Gallup poll 53 percent of Americans say Republicans will do a better job of keeping America prosperous over the short term while only 39 percent thought that of the Democrats.

Fifty-seven percent of Americans said that the Republicans would do a better job keeping America safe, while only 35 percent favor the Democrats. These are historically high Republican advantages.

Here are the hard, unpleasant facts: The Republicans have a likely nominee who is facing 91 charges. The Republicans in Congress are so controlled by a group of performative narcissists, the whole House has been reduced to chaos. And yet they are still leading the Democrats in these sorts of polling measures

There is no other potential nominee who is so credibly steeped in knowing what life is like for working- and middle-class people, just as there was no other potential nominee in 2020. After watching him for a quarter-century, I think he is genuinely most comfortable when he is hanging around the kinds of people he grew up with. He doesn’t send out any off-putting faculty lounge vibes. On cultural matters he is most defined by what he doesn’t do — needlessly offend people with overly academic verbiage and virtue signaling. That is why I worry when he talks too stridently about people on the right, when he name-calls and denounces wide swaths of people as MAGA.

Over the last half-century, the Democrats have become increasingly the party of the well-educated metropolitan class.

This is about something deeper than Joe Biden’s age. More and more people are telling pollsters that the Republicans, not the Democrats, care about people like me.

But Democrats are losing something arguably more important than a reliable base of supporters. The party is in danger of letting go of an ethos, a heritage, a tradition. The working-class heart and soul the Democrats cultivated through the Roosevelt, Truman and Kennedy years rooted Democratic progressivism in a set of values that emphasized hard work, neighborhood, faith, family and flag. Being connected to Americans’ everyday experiences kept the party pinioned to the mainstream.

. It grew prone to taking flights of fancy in policy and rhetoric, be it Medicare for All or “defund the police,” going to places where middle-of-the-road voters would not follow. It became more vulnerable to the insular outlooks of its most privileged and educated members.

And that is the fact I keep returning to. Biden is not what ails the party. As things stand, he is the Democrats’ best shot at curing what ails the party.

today, the party is bleeding working-class voters of all varieties. As John B. Judis and Ruy Teixeira point out in their forthcoming book, “Where Have All the Democrats Gone?” Democrats have been losing ground among Hispanics for the last few years. In 2012, Barack Obama carried nonwhite voters without a college degree by a 67-point margin. In 2020, Biden carried this group with a 48-point margin. Today, the Democratic ticket leads among this group by a paltry 16 points

These cultural and spiritual roots give him not just a style but a governing agenda. He has used the presidency to direct resources to those who live in the parts of the country where wages are lower, where education levels are lower, where opportunities are skimpier. Biden’s ethos harks back to the ethos of the New Deal Democratic Party, but it also harks forward to something — to a form of center-left politics that is culturally moderate and economically aggressive

Something almost spiritual is at play here, not just about whether the Democrats can win in 2024, but who the Democrats are.

I also find myself arriving foursquare at the conclusion that rejecting the president now would be, in the first place, a mistake. He offers the most plausible route toward winning the working- and middle-class groups the Democrats need, the most plausible route toward building a broad-based majority party

But it would be worse than a mistake. It would be a renunciation of the living stream of people, ideas and values that flow at the living depths of the party, a stream that propelled its past glories and still points toward future ones.

the decreasing importance of the printed word, over the past decades, in favour of visual and hyper-concise forms of media, from TV to TikTok. Televised debates require fast reaction times, whereas scientists are used to studying issues at length and only talking about them after thinking.

a successful visual performance is not just about being correct but evoking sympathy in the viewer – about performing. This doesn’t always come easy to scientists.

Whereas once it was thought that the future would necessarily be better than the present, faith in progress – in the magnificent and progressive fortunes of humans – has been eroded

And just as science used to get the credit for progress, so now it receives the blame for decline (real or just perceived, it doesn’t matter). Science is sometimes felt to be a bad teacher who has led us in the wrong direction, and changing this perception is not easy.

In a nutshell, scientists are thought to be part of the elite and, therefore, not trustworthy. And the increasing interest by a fraction of scientists in patenting knowledge and making individual financial gains from discoveries reinforces this identification with the elite

a fundamental reality: science makes fair predictions that become reliable after the gradual formation of a scientific consensus. The construction of consensus is the process that makes the real difference – it involves the whole scientific community and that cannot be manipulated.

this lack of trust can have disastrous effects: if citizens do not trust science, we will not be able to fight global warming, infectious diseases, poverty and hunger, and the depletion of the planet’s natural resources.

A great coordinated effort is needed, and this will only be possible if there is a full understanding of the dramatic nature of the problem

A part of the human and financial resources devoted to the advancement of science must be used to discuss with citizens, through education and media and outreach programmes, what science really is: the most reliable and honest tool for understanding the world and predicting the future.

It is also important that we scientists talk about not just our successes, but our mistakes, doubts and hesitations. Often there is no trace, in the public scientific discourse, of the toil of the scientific process and the doubts that accompany it.

So, too, does the view that the strongest defense of the humanities lies not in the appeal to their utility — that literature majors may find good jobs, that theaters may economically revitalize neighborhoods

— but rather in the appeal to their defiantly nonutilitarian character, so that individuals can know more than how things work, and develop their powers of discernment and judgment, their competence in matters of truth and goodness and beauty, to equip themselves adequately for the choices and the crucibles of private and public life.

We are not becoming transhumanists, obviously. We are too singular for the Singularity. But are we becoming posthumanists?

In American culture right now, as I say, the worldview that is ascendant may be described as posthumanism.

The posthumanism of the 1970s and 1980s was more insular, an academic affair of “theory,” an insurgency of professors; our posthumanism is a way of life, a social fate.

In “The Age of the Crisis of Man: Thought and Fiction in America, 1933-1973,” the gifted essayist Mark Greif, who reveals himself to be also a skillful historian of ideas, charts the history of the 20th-century reckonings with the definition of “man.

Here is his conclusion: “Anytime your inquiries lead you to say, ‘At this moment we must ask and decide who we fundamentally are, our solution and salvation must lie in a new picture of ourselves and humanity, this is our profound responsibility and a new opportunity’ — just stop.” Greif seems not to realize that his own book is a lasting monument to precisely such inquiry, and to its grandeur

“Answer, rather, the practical matters,” he counsels, in accordance with the current pragmatist orthodoxy. “Find the immediate actions necessary to achieve an aim.” But before an aim is achieved, should it not be justified? And the activity of justification may require a “picture of ourselves.” Don’t just stop. Think harder. Get it right.

Greif’s book is a prehistory of our predicament, of our own “crisis of man.” (The “man” is archaic, the “crisis” is not.) It recognizes that the intellectual history of modernity may be written in part as the epic tale of a series of rebellions against humanism

Who has not felt superior to humanism? It is the cheapest target of all: Humanism is sentimental, flabby, bourgeois, hypocritical, complacent, middlebrow, liberal, sanctimonious, constricting and often an alibi for power

what is humanism? For a start, humanism is not the antithesis of religion, as Pope Francis is exquisitely demonstrating

The worldview takes many forms: a philosophical claim about the centrality of humankind to the universe, and about the irreducibility of the human difference to any aspect of our animality

And posthumanism? It elects to understand the world in terms of impersonal forces and structures, and to deny the importance, and even the legitimacy, of human agency.

a methodological claim about the most illuminating way to explain history and human affairs, and about the essential inability of the natural sciences to offer a satisfactory explanation; a moral claim about the priority, and the universal nature, of certain values, not least tolerance and compassion

There have been humane posthumanists and there have been inhumane humanists. But the inhumanity of humanists may be refuted on the basis of their own worldview

the condemnation of cruelty toward “man the machine,” to borrow the old but enduring notion of an 18th-century French materialist, requires the importation of another framework of judgment. The same is true about universalism, which every critic of humanism has arraigned for its failure to live up to the promise of a perfect inclusiveness

there has never been a universalism that did not exclude. Yet the same is plainly the case about every particularism, which is nothing but a doctrine of exclusion; and the correction of particularism, the extension of its concept and its care, cannot be accomplished in its own name. It requires an idea from outside, an idea external to itself, a universalistic idea, a humanistic idea.

Asking universalism to keep faith with its own principles is a perennial activity of moral life. Asking particularism to keep faith with its own principles is asking for trouble.

there is no more urgent task for American intellectuals and writers than to think critically about the salience, even the tyranny, of technology in individual and collective life

Here is a humanist proposition for the age of Google: The processing of information is not the highest aim to which the human spirit can aspire, and neither is competitiveness in a global economy. The character of our society cannot be determined by engineers.

“Our very mastery seems to escape our mastery,” Michel Serres has anxiously remarked. “How can we dominate our domination; how can we master our own mastery?”

universal accessibility is not the end of the story, it is the beginning. The humanistic methods that were practiced before digitalization will be even more urgent after digitalization, because we will need help in navigating the unprecedented welter

Searches for keywords will not provide contexts for keywords. Patterns that are revealed by searches will not identify their own causes and reasons

The new order will not relieve us of the old burdens, and the old pleasures, of erudition and interpretation.

Is all this — is humanism — sentimental? But sentimentality is not always a counterfeit emotion. Sometimes sentiment is warranted by reality.

The persistence of humanism through the centuries, in the face of formidable intellectual and social obstacles, has been owed to the truth of its representations of our complexly beating hearts, and to the guidance that it has offered, in its variegated and conflicting versions, for a soulful and sensitive existence

a complacent humanist is a humanist who has not read his books closely, since they teach disquiet and difficulty. In a society rife with theories and practices that flatten and shrink and chill the human subject, the humanist is the dissenter.

That requires a movement that takes innovation as seriously as it takes affordability.

what Bastani sees clearly is that the world we should want requires more than redistribution. It requires inventions and advances that render old problems obsolete and new possibilities manifold.

the authors urge conservatives to tackle costs directly. Too often, Republican proposals to cut government spending are just shell games that shift costs onto individuals. The conservative enthusiasm for moving Medicare beneficiaries onto (often more expensive!) private plans “risks being little more than an accounting trick — a purely nominal change in ‘who pays’ that would do little to address the underlying sources of cost growth.”

For now, though, it’s Democrats who are starting to take supply-side concerns seriously.

A problem of our era is there’s too little utopian thinking, but one worthy exception is Aaron Bastani’s “Fully Automated Luxury Communism,” a leftist tract that puts the technologies in development right now — artificial intelligence, renewable energy, asteroid mining, plant- and cell-based meats, and genetic editing — at the center of a postwork, postscarcity vision.

“What if everything could change?” he asks. “What if, more than simply meeting the great challenges of our time — from climate change to inequality and aging — we went far beyond them, putting today’s problems behind us like we did before with large predators and, for the most part, illness? What if, rather than having no sense of a different future, we decided history hadn’t actually begun?”

There are sharp limits on supply in all of these sectors because regulators make it hard to increase supply (zoning laws make it difficult to build housing), training and hiring workers is expensive (adding classrooms means adding teachers and teacher aides, and expanding health insurance requires more doctors and nurses) or both. “This can result in a vicious cycle in which subsidies for supply-constrained goods or services merely push up prices, necessitating greater subsidies, which then push up prices, ad infinitum,” they write.

Progressives have long known to look for problems on the demand side of the economy — to ask whether there are goods and services people need that they cannot afford. That will make today fairer, but to ensure tomorrow is radically better, we need to look for the choke points in the future we imagine, the places where the economy can’t or won’t supply the things we need. And then we need to fix them.

In a world where two-thirds of emissions now come from middle-income countries like China and India, the only way for humanity to both address climate change and poverty is to invent our way to clean energy that is plentiful and cheap and then spend enough to rapidly deploy it.

It is true that European countries free-ride off the high cost we pay for drugs, because it’s the U.S. market that drives innovation. But that doesn’t mean we’d be better off paying their prices, if that meant new drug development slowed. We don’t just want everyone to have health insurance in the future. We want them to be healthier, freed from diseases and pain that even the best health insurance today cannot cure or ease.

It’s ludicrous to say that the pharmaceutical system we have now is oriented toward innovation. It’s oriented toward profit; sometimes that intersects with innovation and sometimes it doesn’t.

We should combine price controls with new policies to encourage drug development. That could include everything from more funding of basic research to huge prizes for discovering drugs that treat particular conditions to more public funding for drug trials.

Years ago, Bernie Sanders had an interesting proposal for creating a system of pharmaceutical prizes in which companies could make millions or billions for inventing drugs that cured certain conditions, and those drugs would be immediately released without exclusive patent protections. Focusing on the need to make new drugs affordable while ignoring the need to make more of them exist is like trimming a garden you’ve stopped watering.

this is a lesson progressives are, increasingly, learning. This is clearest on climate. Much of the spending in the Biden agenda is dedicated to increasing the supply of renewable energy and advanced batteries while building the supply of carbon-neutral transportation options.

In a blog post, Jared Bernstein, a member of President Biden’s Council of Economic Advisers, and Ernie Tedeschi, a senior policy economist for the council, framed the Biden agenda as “an antidote for inflationary pressure” because much of it expands the long-term supply of the economy.

Climate change is the most pressing example

look closely and you can see something new and overdue emerging in American politics: supply-side progressivism.

“Once again, we saw that what voters say in polls can be very different than what they do when faced with the stark choice between Democrats who are fighting for a better life for families and dangerous candidates who are dead set on taking away their rights and freedoms,”

But the common thread through most of the major contests was the Democrats’ continuing strength in racially diverse, well-educated major metropolitan areas, which tend to support liberal positions on cultural issues such as abortion and LGBTQ rights. Those large population centers have trended Democratic for much of the 21st century. But that process accelerated after Trump emerged as the GOP’s leader in 2016, and has further intensified

From a national perspective, the battle for control of the Virginia state legislature probably offered the most important signal. The Virginia race presented the same competing dynamics that are present nationally. Though Biden won the state by 10 percentage points in 2020, recent polls indicate that more voters there now disapprove than approve of his performance

t Virginia voters gave Republicans a double-digit advantage on economy and crime. Beyond all that, Youngkin raised enormous sums to support GOP legislative candidates and campaigned tirelessly for them.

he results made clear that most Virginia voters did not want to roll back access to abortion in the commonwealth, where it is now legal through 26 weeks of pregnancy. “What Virginia showed us is that the Glenn Youngkin playbook failed,” Mini Timmaraju, the CEO of Reproductive Freedom for All, an abortion-rights group, told me last night. “We showed that even Republican voters in Virginia weren’t buying it, didn’t go for it, saw right through it.”

a clear message from the party’s performance yesterday is that, however disenchanted voters are with the country’s direction under Biden, Democrats can still win elections by running campaigns that prompt voters to consider what Republicans would do with power. “We have an opening here with the effective framing around protecting people’s freedoms,” Fernandez Ancona told me. “Now we can push forward on the economy.”

Degrowth

notice I said the word “some”. Many progressive visions, like greater economic equality, the closing of racial wealth gaps, and the reversal of climate change, are things I want!

what I’m arguing is that some of the big ideas progressives embraced in the heady rush of the 2010s are misguided and should be discarded, in order to work toward utopias that human beings would actually like to live in.

Here’s a list of four such visions.

When Brad challenged me to list some examples of dystopian progressive visions, I immediately said “degrowth”, and he agreed.

halting or reversing economic growth — an idea that has become fashionable among some progressive circles in the past decade — is both unworkable and undesirable as a way to limit humanity’s environmental impact

First, I argued that the drop in living standards that degrowth would require makes it a political nonstarter, and the amount of global central planning involved would be impossible to implement:

I also argued that solving climate change requires growth, since it’ll take a lot of economic output to replace our energy sources with solar and wind and batteries. And then once we do switch to those energy sources, they’ll be so cheap (thanks to learning curves) that we’ll actually have sustainably higher consumption than before.

As I explained in that second post, I view degrowth partly as an attempt to valorize national decline, which is why the idea is much more popular in Europe than in the U.S.

The expulsion of “colonizers”

ome progressives in the U.S. have begun to talk about an entirely different type of “decolonization” — the expulsion of “settler colonial” populations from regions that their ancestors settled in.

“When you show people deepfakes and generative AI, a lot of times they come out of the experiment saying, ‘I just don’t trust anything anymore,’” says David Rand, a professor at MIT Sloan who studies the creation, spread and impact of misinformation.

The signs that an image is AI-generated are easy to miss for a user simply scrolling past, who has an instant to decide whether to like or boost a post on social media. And as generative AI continues to improve, it’s likely that such signs will be harder to spot in the future.

The combination of easily-generated fake content and the suspicion that anything might be fake allows people to choose what they want to believe, adds DiResta, leading to what she calls “bespoke realities.”

Examples of misleading content created by generative AI are not hard to come by, especially on social media

This problem, which has grown more acute in the age of generative AI, is known as the “liar’s dividend,

“What our work suggests is that most regular people do not want to share false things—the problem is they are not paying attention,”

People’s attention is already limited, and the way social media works—encouraging us to gorge on content, while quickly deciding whether or not to share it—leaves us precious little capacity to determine whether or not something is true

are now using its existence as a pretext to dismiss accurate information

in the course of a lawsuit over the death of a man using Tesla’s “full self-driving” system, Elon Musk’s lawyers responded to video evidence of Musk making claims about this software by suggesting that the proliferation of “deepfakes” of Musk was grounds to dismiss such evidence. They advanced that argument even though the clip of Musk was verifiably real

If the crisis of authenticity were limited to social media, we might be able to take solace in communication with those closest to us. But even those interactions are now potentially rife with AI-generated fakes.

what sounds like a call from a grandchild requesting bail money may be scammers who have scraped recordings of the grandchild’s voice from social media to dupe a grandparent into sending money.

companies like Alphabet, the parent company of Google, are trying to spin the altering of personal images as a good thing. 

With its latest Pixel phone, the company unveiled a suite of new and upgraded tools that can automatically replace a person’s face in one image with their face from another, or quickly remove someone from a photo entirely.

Joseph Stalin, who was fond of erasing people he didn’t like from official photos, would have loved this technology.

In Google’s defense, it is adding a record of whether an image was altered to data attached to it. But such metadata is only accessible in the original photo and some copies, and is easy enough to strip out.

The rapid adoption of many different AI tools means that we are now forced to question everything that we are exposed to in any medium, from our immediate communities to the geopolitical, said Hany Farid, a professor at the University of California, Berkeley who

To put our current moment in historical context, he notes that the PC revolution made it easy to store and replicate information, the internet made it easy to publish it, the mobile revolution made it easier than ever to access and spread, and the rise of AI has made creating misinformation a cinch. And each revolution arrived faster than the one before it.

Not everyone agrees that arming the public with easy access to AI will exacerbate our current difficulties with misinformation. The primary argument of such experts is that there is already vastly more misinformation on the internet than a person can consume, so throwing more into the mix won’t make things worse.

it’s not exactly reassuring, especially given that trust in institutions is already at one of the lowest points in the past 70 years, according to the nonpartisan Pew Research Center, and polarization—a measure of how much we distrust one another—is at a high point.

“What happens when we have eroded trust in media, government, and experts?” says Farid. “If you don’t trust me and I don’t trust you, how do we respond to pandemics, or climate change, or have fair and open elections? This is how authoritarianism arises—when you erode trust in institutions.”

Though Ms. Ocasio-Cortez struggled early on to articulate her views on the Middle East and has never visited the region, the 34-year-old congresswoman has come to embody that generational shift.

She uses terms like “apartheid” and “oppression,” loathed by Israel’s defenders, to describe the treatment of Palestinians. Last week, she called the American Israel Public Affairs Committee, the most powerful pro-Israel lobby and one of Mr. Torres’s top campaign donors, “racist and bigoted.”

“This is pursuing a proven and failed strategy,” Ms. Ocasio-Cortez said in a recent radio interview. “So why do it, why kill kids, why put people in danger, why perpetuate these cycles when we’ve done it so many times, and it’s never kept us safe?”

Mr. Torres has reserved special vitriol for the Democratic Socialists of America, the small but influential leftist group that has pushed for boycotts of Israel and counts Ms. Ocasio-Cortez as a member. In an interview, he said that the D.S.A. was trying to infiltrate the Democratic Party “to impose the ideological litmus tests on Israel” and “cleanse” those who disagree with them. He said he was on a “publicly stated mission” to undermine it.

“You can see how hard Alexandria is trying to listen compassionately across the lines of this conflict,” said Brad Lander, the left-leaning New York City comptroller who is the highest-ranking Jewish city official. “I’m not saying anyone is doing it perfectly, but there is a difference between trying and not trying.”

Ms. Ocasio-Cortez, who did not agree to an interview, met in Washington last month with the families of Jewish hostages kidnapped by Hamas. She has repeatedly condemned the group and supports a two-state solution shunned by some on the left. And at a time when many liberal Jews feel they are being abandoned by the left, she has warned about “disgusting and unacceptable” antisemitism in a post to 8.4 million Instagram followers, saying, “No movement of integrity should tolerate it.”

“I do worry that the next generation is increasingly indoctrinated with anti-Israel hate so virulent that it renders them indifferent to the coldblooded murder of Jews in Israel,”

His views are no surprise to those who watched Mr. Torres, a proud college dropout and defender of public housing, evolve from left-aligned political upstart to more traditional Democratic congressman

It was his first trip abroad, and Mr. Torres said witnessing both the fragility of the frontier and Tel Aviv’s openness to gay life left him with “profound empathy” for Israel and a commitment to a two-state solution.

Lesson #5: Proportionality should be a guideline in war.

McNamara talks about the proportions of cities destroyed in Japan by the US before the dropping of the nuclear bomb, comparing the destroyed Japanese cities to similarly-sized cities in the US: Tokyo, roughly the size of New York City, was 51% destroyed; Toyama, the size of Chattanooga, was 99% destroyed; Nagoya, the size of Los Angeles, was 40% destroyed; Osaka, the size of Chicago, was 35% destroyed; Kobe, the size of Baltimore, was 55% destroyed; etc. He says LeMay once said that, had the United States lost the war, they would have been tried for war crimes, and agrees with this assessment.

Lesson #7: Belief and seeing are both often wrong. McNamara affirms Morris' framing of lesson 7 in relation to the Gulf of Tonkin incident: "We see what we want to believe."

Lesson #8: Be prepared to reexamine your reasoning. McNamara says that, even though the United States is the strongest nation in the world, it should never use that power unilaterally: "if we can't persuade nations with comparable values of the merit of our cause, we better reexamine our reasoning."

We, the richest nation in the world, have failed in our responsibility to our own poor and to the disadvantaged across the world to help them advance their welfare in the most fundamental terms of nutrition, literacy, health and employment.

we are not omniscient. If we cannot persuade other nations with similar interests and similar values of the merits of the proposed use of that power, we should not proceed unilaterally except in the unlikely requirement to defend directly the continental U.S., Alaska and Hawaii.

War is a blunt instrument by which to settle disputes between or within nations, and economic sanctions are rarely effective. Therefore, we should build a system of jurisprudence based on the International Court—that the U.S. has refused to support—which would hold individuals responsible for crimes against humanity.

If we are to deal effectively with terrorists across the globe, we must develop a sense of empathy—I don't mean "sympathy," but rather "understanding"—to counter their attacks on us and the Western World.

We underestimated the power of nationalism to motivate a people to fight and die for their beliefs and values.

Our misjudgments of friend and foe, alike, reflected our profound ignorance of the history, culture, and politics of the people in the area, and the personalities and habits of their leaders.

We failed then—and have since—to recognize the limitations of modern, high-technology military equipment, forces, and doctrine. We failed, as well, to adapt our military tactics to the task of winning the hearts and minds of people from a totally different culture.

We did not recognize that neither our people nor our leaders are omniscient. Our judgment of what is in another people's or country's best interest should be put to the test of open discussion in international forums. We do not have the God-given right to shape every nation in our image or as we choose.

We did not hold to the principle that U.S. military action … should be carried out only in conjunction with multinational forces supported fully (and not merely cosmetically) by the international community.

5. Proportionality should be a guideline in war

8. Be prepared to re-examine your reasoning

1. The human race will not eliminate war in this century, but we can reduce the brutality of war—the level of killing—by adhering to the principles of a "Just War," in particular to the principle of "proportionality."

5. We, the richest nation in the world, have failed in our responsibility to our own poor and to the disadvantaged across the world to help them advance their welfare in the most fundamental terms of nutrition, literacy, health and employment.

8. War is a blunt instrument by which to settle disputes between or within nations, and economic sanctions are rarely effective.

Mr. Christie’s criticism of the former president’s Middle East record is significant. The peace agreements struck by Israel with the United Arab Emirates, Bahrain, Sudan and Morocco, collectively known as the Abraham Accords, are widely seen as perhaps Mr. Trump’s most important diplomatic accomplishment. And Republicans have offered high praise for decisions like moving the United States Embassy in Israel to Jerusalem from Tel Aviv.

Mr. Christie offered higher praise for Mr. Biden’s handling of the Israel-Gaza crisis, including his Oct. 18 visit to Israel, where he met with Prime Minister Benjamin Netanyahu.

He accused Mr. Trump of cynicism in his handling of the once broadly bipartisan U.S.-Israel relationship and held him responsible for fractures over Israel within the Democratic Party.

Mr. Christie was quick to say that he did not blame Mr. Trump for the bloody hostilities in Israel. The timing of Hamas’s attack reflected larger geopolitical dynamics with Iran, Russia and China, he said.

He wholeheartedly embraced every policy pressed by Israel’s conservative government, including moving the embassy, recognizing Israel’s annexation of the Golan Heights, withdrawing from Mr. Obama’s deal with Iran to temper its nuclear ambitions and pursuing regional peace agreements between Israel and the Persian Gulf states that isolated Palestinians and marginalized their demands for political autonomy.

Mr. Christie argued that Democratic voters, in turn, had reflexively opposed anything embraced so wholeheartedly by Mr. Trump, including by electing representatives to Congress like Rashida Tlaib of Michigan and Ilhan Omar of Minnesota, whom they saw as fierce opponents of Mr. Trump. Those new lawmakers on the Democratic left then opened an anti-Israel wing of the Democratic Party that is straining the U.S.-Israel alliance.

Meanwhile, he said, the cause of Israeli-Palestinian peace, once considered the holy grail of presidential diplomacy, was all but forgotten.

Mr. Christie said that President Barack Obama’s policies had been perceived as favoring Israel’s enemies and that Mr. Trump had seized the political opening that presented:

“I don’t think he was equipped to deal in a foreign policy way with a very difficult, if not impossible, issue, right? And I don’t think he has any ambition,” Mr. Christie said. “I think he was looking for what would be relatively direct and easy scores because his view always was political.”

Before arriving in Israel, he spoke of the difficult balancing act between the vital need for Israel to defend its territory and its people and concerns about the growing backlash around the globe.

“We’ve been there after 9/11,” he said. “We understand the visceral need and the practical need to retaliate and degrade Hamas.

“But don’t have exclusively a near-term view,” he advised. “And that’s tricky for somebody like Netanyahu and the political position he’s in at the moment, because, you know, there’s certainly going to be a reckoning whenever the war is considered concluded, as to how Israel got there in the first place.”

“Ultimately, it’s in Israel’s best interest and the world’s best interest. But I think the actions that Hamas took on Oct. 7 has made that resolution significantly more difficult and more long-term. And I think that’s one of the real shames of their actions,”

“I don’t think Trump’s an antisemite,” even though he has routinely espoused stereotypes of Jews, Mr. Christie said. But, he added, Mr. Trump’s “intolerance of everybody” is “what’s contributed to” the surging bigotry.

“He says what he says, without regard to the fact that he’s perceived as a leader and that his words matter,” Mr. Christie said. The bigots “think you’re giving them permission be a bigot,” he added, “and that’s even worse than them thinking you are one.”

“I think he’s a guy of the 1960s from Queens, New York, with certain attitudes that he probably learned from his parents,” Mr. Christie said.

But he was less sympathetic about the bigotries that he said Mr. Trump had unleashed.“His rhetoric contributes to it,” he said. “By his rhetoric, I mean, his intolerance of everybody. Everybody hears that dog whistle a different way.”

“This is a small but significant step in the right direction,”

she was troubled by the court’s failure to acknowledge past transgressions and the lack of a mechanism to enforce the new restrictions.

“It’s good that they did this,” he said. “It’s good that they feel some obligation to respond to public criticism and act like they care.”But, he added, “in terms of the content, it doesn’t seem to move the ball much.”

The main difference between the new code and the one that applies to other federal judges is in its treatment of recusal. In commentary the court issued along with the code, the justices said they must be wary of disqualifying themselves from cases because — unlike judges on lower courts — they cannot be replaced when they do

“Because of the broad scope of the cases that come before the Supreme Court and the nationwide impact of its decisions,” the commentary said, the provision on recusal “should be construed narrowly.”

In all, said James Sample, a law professor at Hofstra University, the new code is a modest improvement.“Will this code of conduct solve the problems?” he asked. “No. There will certainly be questions as to enforcement. There will be questions as to details, and you can quibble over certain of the provisions. But this is a significant step.”

Friedman’s thought, she argues, is more complex and subtle than has been understood: He raised pressing questions about the market, individualism, and the role of the state that will be with us for as long as capitalism endures.

Just as important, his time at Chicago taught Friedman about the intertwining of political, intellectual, and personal loyalties. He became a regular in an informal group of graduate students and junior faculty trying to consolidate the department as a center of free-market thought

by the 1930s, the leading figures at the University of Chicago were deeply committed to what had become known as price theory, which analyzed economic behavior in terms of the incentives and information reflected in prices. The economists who left their mark on Friedman sought to create predictive models of economic decision making, and they were politically invested in the ideal of an unencumbered marketplace.

Friedman was also shaped by older traditions of economic thought, in particular the vision of political economy advanced by thinkers such as Adam Smith and Alfred Marshall. For them, as for him, economics was not a narrow social science, concerned with increasing productivity and efficiency. It was closely linked to a broader set of political ideas and values, and it necessarily dealt with basic questions of justice, freedom, and the best way to organize society.

His libertarian ethos helped seed the far more openly hierarchical social and political conservatism that fuels much of our present-day political dysfunction.

But his fundamental commitments were consistent. In his early work on consumption habits, Friedman sought to puncture the arrogance of the postwar Keynesian economists, who claimed to be able to manipulate the economy from above, using taxes and spending to turn investment, consumption, and demand on and off like so many spigots

Instead, he believed that consumption patterns were dependent on local conditions and on lifetime expectations of income. The federal government, he argued, could do much less to affect economic demand—­and hence to fight recessions—­than the Keynesian consensus suggested.

In 1946, Friedman was hired by the University of Chicago, where he shut down efforts to recruit economists who didn’t subscribe to free-market views.

He was also legendary for his brutal classroom culture. One departmental memo, trying to rectify the situation, went so far as to remind faculty to please not treat a university student “like a dog.” What had started as a freewheeling, rebellious culture among the economists in Room Seven wound up as doctrinal rigidity.

Evidence leads her to argue more pointedly that Rose (credited only with providing “assistance”) essentially co-wrote Capitalism and Freedom (1962).

Burns implicitly exposes some of the limitations of Friedman’s focus on the economic benefits of innate individual talent. He had more than nature to thank for producing associates of such high caliber, ready to benefit him in his career. Culture and institutions clearly played a large role, and sexual discrimination during the 1930s, ’40s, and ’50s ensured that professional paths were anything but fair.

The state, he acknowledged, would have to take some responsibility for managing economic life—­and thus economists would be thrust into a public role. The question was what they would do with this new prominence.

Almost as soon as the Second World War ended, Friedman began to stake out a distinctive rhetorical position, arguing that the policy goals of the welfare state could be better accomplished by the free market

in Capitalism and Freedom, Friedman made the case that the real problem lay in the methods liberals employed, which involved interfering with the competitive price mechanism of the free market. Liberals weren’t morally wrong, just foolish, despite the vaunted expertise of their economic advisers.

In a rhetorical move that seemed designed to portray liberal political leaders as incompetent, he emphasized efficiency and the importance of the price system as a tool for social policy

For Friedman, the competitive market was the realm of innovation, creativity, and freedom. In constructing his arguments, he envisioned workers and consumers as individuals in a position to exert decisive economic power, always able to seek a higher wage, a better price, an improved product

The limits of this notion emerged starkly in his contorted attempts to apply economic reasoning to the problem of racism, which he described as merely a matter of taste that should be free from the “coercive power” of the law:

Although he personally rejected racial prejudice, he considered the question of whether Black children could attend good schools—and whether, given the “taste” for prejudice in the South, Black adults could find remunerative jobs—less important than the “right” of white southerners to make economic decisions that reflected their individual preferences. In fact, Friedman compared fair-employment laws to the Nuremberg Race Laws of Nazi Germany. Not only was this tone-deaf in the context of the surging 1960s civil-rights movement; it was a sign of how restricted his idea of freedom really was.

s the conservative movement started to make electoral gains in the ’70s, Friedman emerged as a full-throated challenger of liberal goals, not just methods

He campaigned for “tax limitation” amendments that would have restricted the ability of state governments to tax or spend

n a famous New York Times Magazine essay, he suggested that corporations had no “social responsibility” at all; they were accountable only for increasing their own profit

Friedman’s free-market certainties went on to win over neoliberals. By the time he and Rose published their 1998 memoir, Two Lucky People, their ideas, once on the margin of society, had become the reigning consensus.

That consensus is now in surprising disarray in the Republican Party that was once its stronghold. The startling rise in economic inequality and the continued erosion of middle-class living standards have called into question the idea that downsizing the welfare state, ending regulations, and expanding the reach of the market really do lead to greater economic well-being—let alone freedom.

Friedman—despite being caricatured as a key intellectual architect of anti-government politics—had actually internalized an underlying assumption of the New Deal era: that government policy should be the key focus of political action. Using market theory to reshape state and federal policy was a constant theme of his career.

Still, Friedman—­and the libertarian economic tradition he advanced—­bears more responsibility for the rise of a far right in the United States than Burns’s biography would suggest. His strategy of goading the left, fully on display in the various provocations of Free to Choose and even Capitalism and Freedom, has been a staple for conservatives ever since

He zealously promoted the kind of relentless individualism that undergirds parts of today’s right, most notably the gun lobby. The hostile spirit that he brought to civil-rights laws surfaces now in the idea that reliance on court decisions and legislation to address racial hierarchy itself hems in freedom

The opposition to centralized government that he championed informs a political culture that venerates local authority and private power, even when they are oppressive

his insistence (to quote Capitalism and Freedom) that “any … use of government is fraught with danger” has nurtured a deep pessimism that democratic politics can offer any route to redressing social and economic inequalities.
