In this episode of In Conversation, Lilyanna D'Amato speaks with Paul Kelton about his new book, Hidden Terrors: The Scourge of Cholera in Jackson's America (Oxford UP, 2026), which traces the arrival of the first cholera pandemic in the United States, in the 1830s. Drawing on various historical documents, including family papers, letters, and newspaper accounts from the time, Kelton examines how ordinary Americans reacted to the strange disease and how the country’s ideologies and inequalities resulted in loss of life on a mass scale.

Silence is frequently considered negative or harmful in both everyday life – for example, when we are silenced – as well as in psychiatry, where poverty of speech is a symptom of depression and pressure of speech is a symptom of mania. In Silence in Mood Disorders: A Philosophical Investigation (Routledge, 2027), Dan Degerman argues for the need to consider silence in mental disorders in a nuanced way that recognizes different forms of silence and different, including positive, ways silences of speech and inner speech can be experienced. The poverty of speech in depression may lead to the fetishizing of silence-breaking that can cause more distress to a patient who simply does not have anything they want to say, while the pressure of speech in mania may involve disruption in a multicomponent capacity to reliably initiate and maintain silence that is usually habitual and occasionally deliberate. Degerman, who is a research fellow at the University of Bristol on the Epistemic Injustice in Health Care Project, provides an analysis of different types of silence, discusses first-person experiences of being silent in depression and mania, and points to ways in which philosophers and clinicians can enrich their understandings and practices involving silences.

It has long been understood that illness is influenced not only by our bodies' physiology, but also language, culture, and meaning. Healing and the Invention of Metaphor: Towards a Poetics of Illness Experience (Cambridge UP, 2025), written by renowned cultural psychiatrist Laurence Kirmayer, explores of the influence of metaphor, narrative, and imagination in experiences of suffering and processes of healing across cultures. It emphasizes how metaphor can open a window to the hidden mechanisms of healing driven by meaning and symbolism, myth and imagination. At the same time, it offers a rigorous critical account of the metaphors embedded in the epistemology and practice of contemporary biomedicine, psychiatry, and psychotherapy. In doing so, it exposes the sociomoral and political dimensions of these dominant approaches to understanding and treating illness.

Laurence J. Kirmayer is Distinguished James McGill Professor and Director of the Division of Social and Transcultural Psychiatry at McGill University. He directs the Culture & Mental Health Research Unit at the Institute of Community and Family Psychiatry of the Jewish General Hospital in Montreal. He is a fellow of the Canadian Academy of Health Sciences and the Royal Society of Canada.

Dr. Anya Daly is Senior Lecturer in Philosophy and Ethics in the School of Arts and Society, University of Tasmania. Interdisciplinary collaborations are at the core of Anya’s research interests. She investigates the intersections of phenomenology with philosophy of mind, the philosophy of perception, the philosophy of psychiatry, embodied and social cognition, enactivism, ethics, aesthetics and Buddhist Philosophy.

As overdose deaths continue to mount and debates rage over harm reduction, drug policy, and homelessness, Hit Doctors: Care, Harm, and the Art of Survival (U California Press, 2026) offers a crucial on-the-ground perspective pointing to a humane future.

Finding a vein is difficult. As veins collapse and scar over, it becomes almost impossible. For millions of Americans who inject drugs and can’t do it alone, the solution is to find someone who can. Enter the “hit doctor.” Though uncredentialed, hit doctors develop expertise through necessity, providing injection assistance and addressing needs that dominant medical systems exclude or criminalize. They share the same conditions as the people they serve: sleeping in encampments and alleys, living in cramped single-room-occupancy hotels, suffering from untreated illness and trauma, and grieving friends who keep dying. Sarah Brothers spent more than seven years observing and interviewing hit doctors and their clients across San Francisco. Hit Doctors is an intimate portrait of the daily lives, relationships, and ethical worlds of people managing extraordinary hardship at a pivotal moment, when fentanyl arrived and thousands began dying annually. Brothers’s long-term ethnography yields critical insights. People seeking help strongly prefer women hit doctors, perceived as more careful and less likely to turn violent. But even as their expertise is valued, hit doctors are targets for abuse, and they suffer as the people they care for decline and die. That is the cost of trying to keep each other alive when formal systems of support have failed.

Brothers joins host Emily Dufton to discuss the years of work behind her new book, the people she studied and the relationships she built with them.

Emily Dufton is the author of Grass Roots: The Rise and Fall and Rise of Marijuana in America (Basic Books, 2017). Her new book, Addiction, Inc.: Medication-Assisted Treatment and America's Forgotten War on Drugs, was released in 2026.

In the early twentieth century, most US states established eugenics programs to improve the human race through selective breeding. North Carolina ran one of the nation's most aggressive programs; between 1927 and 1977, at least 5,700 people were sterilized and thousands more were committed to institutions. While sterilizations in the 1950s and 1960s disproportionately targeted Black women receiving public assistance, the program's early focus was on poor white women. These policies were framed as scientific and progressive, yet they were deeply intertwined with racial and class biases, reflecting long-standing social hierarchies in the South. Anna Krome-Lukens examines those early years and reveals how such white reformers as social workers, politicians, and activists promoted the principles of eugenics while shaping the emerging welfare state before and during the New Deal. Tracing this history, the book illuminates how North Carolina's eugenics programs influenced the modern welfare state and how their legacy continues to shape debates over social policy today.

The episode brings the Book Review Managing Editor of the Journal of Women's History, Ariel Schnee (History PhD Candidate, University of Oklahoma), into conversation with the book's author, historian and scholar of public policy Dr. Anna Krome-Lukens (University of North Carolina-Chapel Hill). Copies of Strong State, Weak Links: Eugenics and the Southern Politics of Welfare (UNC Press, 2026) can be found at the University of North Carolina Press website.

What drives someone to challenge the status quo to prevent disaster? In The Preventioneers: Diseases, Disasters, and the Discoveries That Changed Our World with Barry R Davis (JHU Press, 2026), Barry R. Davis chronicles the work of bold individuals who recognized the warning signs of catastrophe and intervened before tragedy could strike. With stories that include fire, disease, climate change, and public health, Davis illuminates the efforts of those who confronted indifference, ignorance, and inertia to shift society's focus from reaction to prevention.

Through real-world case studies and historical research, The Preventioneers introduces readers to a diverse cast of problem-solvers who identified threats, persuaded skeptics, and devised practical solutions. In colonial Boston, a young Benjamin Franklin witnessed one of the city's most devastating fires. Haunted by that memory, Franklin grew into a lifelong advocate for fire prevention. Ignaz Semmelweis and Sara Josephine Baker fought to raise awareness of and prevent child and maternal mortality. Richard Doll's work to establish the link between smoking and lung cancer revealed the danger of what many viewed as a harmless activity. These inspiring stories exemplify the central message of the book: Prevention is a powerful form of civic action. Their work underscores how principles of prevention transcend fields, whether addressing maternal mortality, auto safety, cancer, or climate change.

Davis underscores that successful prevention requires more than knowledge; it also demands courage, strategy, and relentless advocacy. In doing so, The Preventioneers introduces a framework for thinking about how societies can act early, save lives, and build a healthier, more resilient future.
