ABSTRACT:

As global warming became a cause of concern in the 1980s, researchers and climate activists initially paid little attention to the possible health effects of a warmer world. This changed quickly between 1985 and 1989, when scientists working on contracts with the US Department of Energy and the Environmental Protection Agency extrapolated from existing knowledge about the impact of weather on health to speculate about how global warming would impact health. However, they downplayed the impact of their contributions by highlighting the uncertainty in their models and the adaptability of human societies. Since that time, physicians and other health scientists have maintained a steady drumbeat of warnings about the health effects of global warming. They have published widely in the medical literature and participated actively in international scientific collaborations. Their research has significantly increased the breadth and depth of climate-health science and shown that measurable impacts of global warming have already begun. But as the many climate crises of 2023 show, action against global warming remains inadequate. Is it still reasonable to hope that health advocacy will incite communities and politicians to act? The history of climate and health advocacy reveals many obstacles that must be overcome.

ABSTRACT:

How does the diagnosis process work? This essay traces the philosophical underpinnings of diagnosis from Hume through Kant, Peirce, and Popper, analyzing how pathologists amalgamate sensibility, intuition, and imagination to form new hypotheses that can be tested by evidence and experience.

ABSTRACT:

Psychedelic substances have great promise for the treatment of many conditions, and they are the subject of intensive research. As with other medical treatments, both research and clinical use of psychedelics depend on our ability to ensure informed consent by patients and research participants. However, some have argued that informed consent for psychedelic use may be impossible, because psychedelic experiences can be transformative in the sense articulated by L. A. Paul (2014). For Paul, transformative experiences involve either the acquisition of knowledge that cannot be obtained in any other way or changes in the self. Either of these characteristics may appear to undermine informed consent. This article argues, however, that there is limited evidence that psychedelic experiences are transformative in Paul's sense, and that they may not differ in their transformative features from other common medical experiences for which informed consent is clearly possible. Further, even if psychedelic experiences can be transformative, informed consent is still possible. Because psychedelic experiences are importantly different in several respects from other medical experiences, this article closes with recommendations for how these differences should be reflected in informed consent processes.

Against a backdrop of post-pandemic malaise, diseases of despair, and a fragmented mental health care system, psychedelics have enjoyed a resurgence of interest as powerful psychotherapeutic agents and as catalysts of personal growth. The true power of these substances—some of which are considered sacramental by Indigenous peoples—has been shrouded for half a century by cultural mythology, political propaganda, and misuse. From about 1940 to 1970, psychedelics including psilocybin and LSD were studied and used by clinicians to treat a range of psychiatric disorders from alcoholism and depression in adults to "autistic schizophrenia" in children.

In June 1971, the Nixon administration's racist and illiberal War on Drugs inaugurated what was essentially a total ban on psychedelics. Society was robbed of half a century of scientific progress, and one can only speculate how differently our society might now function, and how many people might have been spared the trauma of mental illness and incarceration. Thankfully, it appears the time has arrived for psychedelic medicines to be decriminalized and included again in the pharmacopeia.

In June 2023, a group of psychedelic researchers, therapists, bioethicists, Indigenous scholars, and advocates met at the Banbury Conference Center at Cold Spring Harbor Laboratory. There, this interdisciplinary group discussed several pressing ethical issues in psychedelics research and treatment that continue to [End Page 114] challenge the field. The aim of this meeting was to develop a bioethical framework for the use of psychedelics in mainstream medical settings. That is, how should psychedelics be employed responsibly by everyday clinicians, including psychiatrists, psychologists, social workers, and other behavioral health-care providers? This special section offers a sampling of three topics in psychedelic bioethics raised by the Banbury group, several of whom appear as coauthors.

In our first paper, Logan Neitzke-Spruill and colleagues offer an overview of explanatory models describing the therapeutic mechanisms of psychedelic substances and how each of these models generates unique ethical quandaries. Starting from molecular biology and moving to neural circuitry and networks, neurobiological models now propel contemporary scientific research into psychedelics. Knowing how these substances work on a molecular level may offer promising ways forward in the development of new molecules designed to treat serious mental illnesses and other neurologic conditions. Perhaps neuroplastic mechanisms will be harnessed to develop new therapies without necessitating a psychedelic trip—a controversial premise discussed in our third paper, by Katherine Cheung, Brian Earp, and David Yaden.

ABSTRACT:

This article presents a case for transforming traditional bioethics into "Bios-ethics." This exposition relies on three propositions: (1) the climate emergency is the "Bios emergency"; (2) in the Bios emergency, bioethics must be replaced by Bios-ethics; and (3) the top and overwhelming priority of Bios-ethics is to address the Bios emergency. Biocentrism, habitat, and environmental ethics are discussed in light of their contribution to the development of Bios-ethics, and potential lines of research in Bios-ethics are outlined. The urgency of undertaking substantive conceptual and practical innovations in response to our current danger is emphasized throughout.

Surprisingly, the 1977 "Russian flu" H1N1 pandemic influenza virus was genetically indistinguishable from strains that had circulated decades earlier but had gone extinct in 1957. This essay puts forward the most plausible chronology to explain the reemergence of the 1977 H1N1 pandemic virus: (1) in January-February 1976, a self-limited small outbreak of a swine H1N1 influenza virus occurred among Army personnel at Fort Dix, New Jersey; (2) in March 1976, the US launched a nationwide H1N1 swine influenza vaccine program; (3) other countries then also launched their own H1N1 R&D efforts; (4) a new H1N1 outbreak, genetically unrelated to the Fort Dix swine virus but indistinguishable from previously extinct H1N1 viruses, was detected early in 1977 in China; (5) the leading Chinese influenza virologist later disclosed that the Chinese military had conducted large H1N1 vaccine R&D studies in 1976. It is likely that the resurrected H1N1 influenza viruses were laboratory-stored strains that were unfrozen and studied as part of the emergency response to a perceived epidemic threat, and that accidentally escaped. The fear of a possible H1N1 pandemic was the critical factor that gave rise to the actual H1N1 pandemic, resulting in an avoidable "self-fulfilling prophecy pandemic."

This essay discusses how two physicians in Britain's National Health Service describe and analyze the conditions of their work: how algorithms and protocols structure the care they can provide and create the dilemmas they and their patients face. In these issues, the NHS is a canary in the mineshaft of contemporary Western health care. NHS practices are understood as how states and state-like entities, Leviathans, seek to render their subjects legible; in this instance, to make both physicians and patients transparently visible to surveillance and administration by standardizing medical work and patient need. Physicians respond by engaging in workarounds, finding ways to provide care despite systemic restrictions.

The Hippocratic oath is such an enduring icon of medical morality that physicians in Nazi Germany invoked it to protest Euthanasie, the systematized killing of weak or sick children, people with incurable diseases, hospitalized criminals (a category applicable to gays), geriatric patients, long-term patients, patients not of German blood (Jews and Romani), and people with disabilities. Several expert witnesses at the 1945 Nuremberg Medical Trial also cited the oath to condemn Nazi physicians' abuse of human research subjects. Noting these invocations, in 1947 the physicians who founded the World Medical Association modernized the Hippocratic oath to convey to future medical students its foundational precepts: benefitting the sick, not harming them, not breaching confidentiality, and not treating patients unjustly, irrespective of their gender or social status. This article presents a historically accurate reading of the oath's strange-seeming passages to show that it does not prohibit abortion, euthanasia (medical aid in dying), or surgery. The article also contends that oath-swearing remains an important asset in teaching clinicians their role responsibilities, and that its ethics supports women's rights to reproductive health care and can valorize challenges to venture-capitalist and for-profit managements that prioritize profitability over providing quality health care for patients.

This article discusses relics housed in the Ringling Circus Museum in Sarasota, Florida: photos, works of art, newspaper clippings, performance records, and scrapbooks of mostly 19th- and 20th-century circus performers with varied, often "unusual," bodies that have been all but forgotten. Encountering these artifacts left the author wonderstruck-a feeling sometimes so abrupt that it heaves us into the conscious presence of others-and left him with a string of complex emotions. In this article, the author attempts to recreate the affective experience of wonder as the performers' images were lifted before him, and to reflect on the ways disability prompts that affective experience of wonder and functions in moral development.

The integration of postmodern thinking in the sciences, especially in biology, has been subject to harsh criticism. Contrary to Enlightenment ideals of objectivity and neutrality in the scientific method, the postmodern stance holds that truth is relative, not universal, and therefore progress is ambiguous. The effect of postmodern thought has ramifications that extend from the distrust of preexisting scientific conclusions to questions about the impact of progress in society. It also reflects skepticism about the scientific endeavor. Especially when postmodern ideas are considered to have gained traction, the anti-postmodern critique has become harsher. At stake is whether postmodern notions are indeed irrelevant, and-even more important-whether they compromise scientific progress. The conditional significance of universals in biology and the role of historicity in the evolutionary process makes biology different from the other natural sciences and subjects it to the postmodern critique. This article argues that rather than being viewed as a science that seeks universals, biology should be viewed as a construct, more relevant to a technology, aiming to attain functionalities. Such recognition may fuel progress and assist biology in attaining its ultimate goal, which is to address the most intricate questions about the living world.
