How worried should Catholics be about the pope’s health?
Pope Leo XIV announced on Sunday that he will undergo surgery this week to remove a “nodule” from his lung. The pope made the announcement at the end of his Sunday Angelus address, asking for prayers. “Dear all, recently, during some checkups, the doctors discovered a nodule in my lung. It was detected at a very early stage and was well-localized,” Leo said. “The doctors felt it was necessary to intervene, and so, following their advice, I decided to have surgery to remove it. The procedure is already scheduled for the next few days. I thank you for your spiritual support and I entrust myself to your prayers.” The Vatican press office subsequently added that Leo is scheduled to undergo surgery at the Gamelli hospital on Tuesday, Oct. 13. The pope is expected to spend up to a week in the Gamelli recovering, after which, for the moment, he is still expected to undertake his largest and longest to-date Apostolic journey, heading to Argentina, Uruguay, and Peru, beginning Nov. 6. Prayers have, understandably, poured in from dioceses around the world, accompanied by the best wishes of heads of state and international institutions. So how worried should Catholics be for the health of the pope? The Vatican’s messaging around Leo’s pending surgery is, in many ways, a new approach to papal health issues. But, despite the pope’s personal candour, the Holy See’s messaging perhaps raises as many questions as it answers. Subscribe — Leo’s decision to announce his own medical status and pending hospital stay during the Sunday Angelus is, it should be said, already something of a big deal. Traditionally, the health of popes simply hasn’t been discussed publicly or officially, until circumstances made it absolutely necessary. Memorably, in 2023 Pope Francis was rushed to the Gemelli in an ambulance, exhibiting signs of cardiac arrest according to many close to him, only for the Sala Stampa to put out a statement insisting he was merely going in for “pre-scheduled” tests. That Pope Leo has decided to announce his condition himself, with remarkable frankness, is a significant comms policy shift around the Apostolic Palace. This might reflect a deliberately more open posture, as opposed to the traditional, otiose evasiveness, and the first fruits of an American pope and American prefect of the Dicastery for Communications favoring honesty as a baseline. Equally, it must be allowed, it could be that the pope’s situation is serious enough that there would be no keeping it under wraps or playing it off, and the decision was made to be as open as possible to head off speculation about the papal health. Certainly, Leo appeared to make every effort to sound reassuring — stressing that, whatever the diagnosis is, exactly, it is “well-localized” and “early stage.” Of course, for everyone listening, talk of a “nodule” in a lung will immediately send thoughts — and prayers — running to concerns about words not used, like “cancer,” “tumor,” “begnin” or “malignant.” To be clear, none of those words may yet be medically appropriate. And there is every reason to believe and assume that Leo is giving almost as much information as he may have himself at this stage. But the context of the pope’s announcement and the timing of his surgery do reasonably raise reasonably serious concerns for Leo. We don’t know, and this isn’t to say anyone has the right to expect to know, when the routine medical checks made this discovery. It could have been last week, last month, or even earlier. As such, it isn’t really possible to say with what kind of urgency Leo is being brought in for surgery. However, there is clearly some serious urgency to the matter. Leo making the announcement and going into hospital this week, of all weeks, means he is having to miss the balance and conclusion of his global meeting of the heads of the world’s bishops conferences, which he convened in Rome this week. That, as the Vatican has announced, has meant some serious changes to the schedule, with the newly minted dean of the College of Cardinals, Cardinal Tagle, subbing in for the closing Mass on Wednesday, and the meeting’s organizers announcing that the final working document/summary of the meeting being delayed until Leo can read and feed into it. Those changes suggest that the timing of Leo’s surgery isn’t of his own choosing, and he is acting on the best medical advice he can get by moving urgently. Had this issue been discovered weeks ago, it seems reasonable to assume the pope would have seen it dealt with before the meeting began. And were it possible to delay it, even by a few days to allow the meeting to conclude as scheduled, the expectation would surely be he’d have opted for that. It cannot be excluded that Leo is simply having to fit in with the schedules of his medical team, but a man who occupies arguably the most important and prominent role in Italy, if not Western Europe, could generally be assumed to be the one whose calendar others work around. All this points to a very recent medical discovery leading to a “days matter” diagnosis, or at least suspected possible diagnosis. Of course, another factor weighing in the balance is Leo’s upcoming apostolic visit to three South American countries, including a return to Peru, where he spent many years as a priest and bishop. It is entirely possible that the doctors, and the pope himself, are more concerned about the potential knock-on effects of surgery, and the time needed for recovery, for a 71-year-old — even one as physically sound and actively sporty as Leo. The pope is due to depart Rome November 6 for his 10-day three-country trip, returning on Nov. 17. It may be that Leo has simply made the decision to allow maximum time for his own post-op recovery, and even allow for potentially unforeseen circumstances, so that he is at full strength for the landmark trip. While it might be an inconvenience, and clearly a last-minute wrench in the works for the Amoris meeting, it is possible that Leo simply weighs the importance of that conference more lightly in the balance than even the possibility of missing his homecoming trip to Peru, or even having to scale back his itinerary for the trip. If that is the case, it would suggest a real abundance of caution by the pope approaching his Latin American tour, and a sobering indication of where Leo ranks the non-synodal meeting currently underway in Rome. In any event, what can be said for certain is that the pope having to take this, of all weeks, out of his schedule for surgery and an extended hospital stay is extremely unfortunate timing. It is clear that this is a decision Leo has made on the advice of his doctors. Together, they clearly consider that the risks of delaying, even by a little as a few days, represents an unacceptable risk for the pope. Even expecting and allowing for Leo’s full and speedy recovery, that should be a very sobering thought for Catholics everywhere. Subscribe

Studying Science in an Anti-Scientific Time
This Chronicle Review Deep Cut was first published in 2025. By Julianne Werlin Thanks for reading The Chronicle Review! Subscribe for free to receive new posts and support my work. Subscribe The last two decades have not been kind to science studies. Already bruised and battered by the “science wars” of the 1990s, by the 2000s sociologists of science — who had long argued that science had to be understood in its human context — were encountering the funhouse-mirror version of their own views in right-wing critiques of climate scientists. It was enough to give some prominent scholars pause. “Was I wrong to participate in the invention of this field known as science studies?” asked Bruno Latour, the most famous sociologist of science in the world, in 2003. “Should we apologize for having been wrong all along? Or should we rather bring the sword of criticism to criticism itself and do a bit of soul-searching here: What were we really after when we were so intent on showing the social construction of scientific facts?” In response, Latour proposed a change of method and attitude. Science studies, now chastened and contrite, would no longer seek to strip facts of their authority, but to enrich and enhance them. What this meant in practice was never fully clear. But his diagnosis of problems resonated, even if his solutions did not. Latour’s exercise in public hand-wringing signaled a shift in mood. By 2016, with the first election of Donald Trump, the idea that skepticism of science was a right-wing position, not a left-wing one, had become a commonplace, discussed eagerly in The New York Times. For liberals, vaccine denial during the Covid era and Trump’s second-term attacks on the funding of scientific research, covered extensively in these pages, added a new urgency to the defense of science on both practical and principled grounds. There was little appetite for a sociology or philosophy of science that emphasized the messiness and missteps of the scientific process rather than its integrity and triumphs. The distinguished historian of science Peter Dear’s new book, The World as We Know It: From Natural Philosophy to Modern Science (Princeton University Press, 2025), which seeks to tell the story of 18th- and 19th-century science for a general public, may seem comfortably remote from these bitter contests. In its 16 short chapters, Dear draws swift, sure sketches of major discoveries from Newton to Einstein, ably guiding the reader through debates on stellar nebulae, animal taxonomy, atomic chemistry, evolution, and other flashpoints in the history of science. But though a work of history, Dear’s book must still negotiate our polarized present. In a blurb on its back cover, the historian of biology Lynn K. Nyhart alludes to the “present moment, when scientific knowledge is being swamped by misinformation and its institutions are under siege.” Dear himself, in his conclusion, refers to the “yard signs” and “bumper stickers” that proclaim “Science Is Real.” One antidote to both anti-science propaganda and to reductive slogans in science’s defense is a robust history and philosophy of science: exactly what Dear’s scholarship has long offered. But his new book illustrates how difficult such work has become. Dear, an emeritus professor of history at Cornell University, is best known as a creative and philosophically minded historian of the Scientific Revolution. His edited volume The Literary Structure of Scientific Argument (1991) analyzed the rhetoric of Galileo’s thought experiments to brilliant effect. Discipline and Experience: The Mathematical Way in the Scientific Revolution (1995) was a major contribution to the analysis of scientific experiments in early modern Europe and beyond, while Revolutionizing the Sciences: European Knowledge in Transition, 1500-1700 (2001), now in its third edition, remains one of the best overviews of the profound epistemological upheavals of 16th- and 17th-century science. But Dear has also ventured into later periods. Nearly two decades ago, in The Intelligibility of Nature: How Science Makes Sense of the World (2006), he turned to the 18th and 19th centuries to sketch a history and theory of scientific knowledge. Aimed at a generalist audience, Dear’s simple prose belied serious philosophical ambitions. Science, Dear argued, has two aspects: “natural philosophy,” the quest to understand the true nature of the universe, and “instrumentality,” the applied skills and technologies that allow us to manipulate the world for human advantage. Both strands are ancient, but the innovation of the phenomenon we call “science” was to yoke them together. As Francis Bacon wrote, “Human knowledge and human power meet in one; for where the cause is not known, the effect cannot be produced,” an insight typically abridged to “knowledge is power.” Or, in Bertrand Russell’s characteristically blunt phrase, science has two functions, “1. to enable us to know things, and 2., to enable us to do things.” So far, so conventional. But Dear took issue with this familiar story in one respect. Bacon’s formula implied that theory and practice could be fused in a single method. In fact, Dear argued, the quest to understand nature and the desire to manipulate it were coupled only loosely. They could come together, but they could also pull apart. Focusing on natural philosophy, the “knowing” half of the scientific circle, he used a series of case studies from cosmology, taxonomy, chemistry, electromagnetism, and quantum theory to show how theories changed over time, in dialogue with practice, but never reducible to it. Take the case of matter, the basic substrate of the physical world. In the 18th and 19th centuries, scientists not only disagreed about what it was, but also about how well it could be known. In 1789, the chemist Antoine Lavoisier dismissed speculation about the atomic composition of chemicals as “discussions entirely of a metaphysical nature,” as he sought to orient chemistry away from philosophical abstraction and toward laboratory results. But in the 19th century, atoms returned with a vengeance in the atomic chemistry of John Dalton, who wanted to explain the underlying structure of nature. It was not just that Dalton and Lavoisier had a different set of experimental results, or even a different theory, Dear showed. What counted as an explanation had changed. In arguing that scientific theories depended on their intelligibility to human beings with complex arrays of beliefs and commitments, Dear was in sympathy with science studies. Key figures such as the sociologist Steven Shapin emphasized the importance of psychological mechanisms like trust in the formation and acceptance of scientific ideas. But in focusing on the scientific pursuit of knowledge, not its politics or economics, Dear resisted the more cynical perspective of some of his colleagues. The Intelligibility of Nature strikes a very different note than Shapin’s collection of a few years later, Never Pure: Historical Studies of Science as If It Was Produced by People With Bodies, Situated in Time, Space, Culture, and Society, and Struggling for Credibility and Authority (2010), to name just one example. Walking a very fine line, Dear depicted science as driven at once by complex social dynamics and by the intellectual power of real discoveries. It was a testament not only to his own acumen but also to the vitality of the field that he was able to do so. Nearly two decades later, The World as We Know It returns to the questions broached in The Intelligibility of Nature. Like Dear’s earlier study, it begins with the Newtonian cosmos and ends with debates between Einstein and Bohr on quantum physics. Beyond its terminal figures, many of the same characters appear in both studies, including the naturalists John Ray and the Comte de Buffon; the chemists Étienne François Geoffroy, Antoine Lavoisier, and John Dalton; as well as Charles Darwin and Michael Faraday, among others. Its subject is nearly identical: As in The Intelligibility of Nature, The World as We Know It considers natural philosophy as opposed to instrumentality, here defined as the “desire to create a picture of what the world is really like — the world as God knows it — rather than simply having instrumental or operational control over it.” The two books also overlap in insights — and sometimes even in language. The reader who has learned in The Intelligibility of Nature that Buffon’s method of classifying animals “reflected his belief in the importance of the senses and empiricism in learning about nature (a doctrine associated with Newton and the philosopher John Locke)” will experience a sense of déjà vu on reading, in The World as We Know It, that the classification “reflects Buffon’s commitment to the epistemological stance of Newton and his philosophical underlaborer John Locke, who stressed the role of the senses in creating natural knowledge.” Later in the passage, we read that, “because of its stress on understanding the ways of life of animals in their environments, Buffon’s approach could almost be labeled (anachronistically) as ‘ecological.’” And again, “an anachronistic way of putting it would be to say that Buffon recommends an ecological mode of understanding.” Likewise, in The Intelligibility of Nature we read of Dalton that he was initially drawn to meteorology, and that: He did a bit of experimental work on these things, especially having to do with the water-holding capacity of gases, but his real interest lay in understanding what, at an underlying natural-philosophical level, was really going on physically.” Whereas, in The World as We Know It: He did experimental work on these things, especially concerning the water-holding capacity of gases — although not at a very refined level quantitatively — but he was continually trying to develop a theoretical conception of what was happening physically. The final full chapter of each book closes on the same resigned note. Intelligibility: These days, most serious work on the natural philosophical underpinnings and implications of quantum mechanics is performed not by physicists but by philosophers of science. Among scientific practitioners themselves, Bohr’s attempt to use instrumentality as sufficient grounds for a respectable science has met with a high degree of success. And again, in The World as We Know It: Bohr’s and Einstein’s concerns are now questions that are mostly discussed by philosophers of science rather than by physicists themselves. The marginalization of these sorts of questions amounts to the demise of natural philosophy, at least in physics, in the 20th century. Quantum mechanics “works,” and that’s good enough for most scientists who encounter it. Examples could be multiplied. When handling the same subject matter, some echoes are inevitable. Scholars should not feel that because they have written “Isaac Newton died in 1727” in one book, in the next they must describe him as perishing, expiring, or meeting his maker. But the repetitions of language and arguments (not to mention six reproduced images) threaded throughout The World as We Know It are more extensive than that. They should have been caught by Princeton University Press or its reviewers, and revised. Because the two books have so much in common, it is easy to see where they diverge. The World as We Know It is a less theoretical work than its predecessor. The sociology of knowledge that organized The Intelligibility of Nature has been reduced in scale and folded into readings and examples. The taut interplay between history and theory, which gave the earlier study so much interest, is there, but it is subtle. In the earlier book, the case studies demonstrated theoretical claims about the character and development of science. In the later work, each narrative of discovery is an end in itself. Insights emerge from the history, but they do not control the organization of the study. With the theory muted, it can be hard to understand the logic uniting Dear’s sprawling history of more than two centuries of scientific knowledge. The 16 brisk chapters cover an enormous amount of material. But the closer the volume edges to comprehensiveness, the more obvious the missing elements become. A chapter on “Institutions and Pedagogy,” describing the birth of the research university, illustrates the problem. Inserted roughly halfway through the book, the unnumbered chapter is designed as an “entr’acte,” in acknowledgement that it does not fit the study’s organization around scientific discoveries. Yet as Dear is well aware, no general history of the development of modern science can bracket its 19th-century institutionalization and professionalization. It was the 19th-century university, after all, that gave us the “scientist,” a term coined by the Cambridge philosopher William Whewell. Dear’s history of scientific discoveries implies a wider social and institutional history, but it remains largely subterranean, only occasionally extruded under the pressure of the narrative. It must be said that the balance is not all on the side of the earlier study. There are some advantages to the more historical, less theoretical organization of The World as We Know It. Dear’s accounts of paradigm shifts are remarkably lucid, no small accomplishment given that they span fields and centuries. He makes excellent use of the wealth of new scholarship on Darwin and his influences, to which he has himself contributed. It is satisfying to see puzzle pieces from Buffon’s natural history, Georges Cuvier’s animal taxonomy, Thomas Robert Malthus’s demography, and Charles Lyell’s geology recombined seamlessly in the Darwinian jigsaw. Likewise, Dear’s discussion of stellar nebulae, divided between chapters two and 15, shows vividly how Newton, Kant, Herschel, and Hubble reimagined insights and observations as they sought to discover whether the diffuse light that filtered through early telescopes was a glowing, gaseous substance or discrete but distant stars. Yet despite such pleasures, the book remains a more modest work than The Intelligibility of Nature. Dear has clearly not changed his views about the history of science. But in the two decades that have elapsed, the discipline and the world around it have changed, making it harder to write a sociologically and philosophically ambitious history of science for the general reader. That is a shame, because in the age of Silicon Valley and biotechnology, both the reciprocity and the tensions Dear identified between the epistemological and instrumental ambitions of science are more evident than ever. In recent years, some of the most exciting new books on the history of science in early modernity have focused precisely on this pressure point. Important studies such as Pamela H. Smith’s From Lived Experience to the Written Word (2022), James Poskett’s Horizons: The Global Origins of Modern Science (2022), and Vera Keller’s The Interlopers: Early Stuart Projects and the Undisciplining of Knowledge (2023) all shed new light on how early modern science negotiated the relationship between its instrumental and epistemological ambitions, or in Russell’s phrase, knowing and doing. There is every opportunity for a philosophically informed approach to draw new insights from this wealth of material. Dear, unfortunately, has not done so in The World as We Know It. But for future scholars of the history of science, his body of work over nearly four decades may provide just the model. Julianne Werlin is an associate professor of English at Duke University.
