ABSTRACT:Psychedelics, including psilocybin, and other consciousness-altering compounds such as 3,4-methylenedioxymethamphetamine (MDMA), currently are being scientifically investigated for their potential therapeutic uses, with a primary focus on measurable outcomes: for example, alleviation of symptoms or increases in self-reported well-being. Accordingly, much recent discussion about the possible value of these substances has turned on estimates of the magnitude and duration of persisting positive effects in comparison to harms. However, many have described the value of a psychedelic experience with little or no reference (...) to such therapeutic benefits, instead seeming to find the experience valuable in its own right. How can we make sense of such testimony? Could a psychedelic experience be valuable even if there were no persisting beneficial effects? If so, how? Using the concept of psychological richness, combined with insights from the philosophy of aesthetics and the enhancement literature, this essay explores potential sources of value in the acute subjective experience, apart from the value derived from persisting beneficial effects.

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: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. (shrink)

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.

ABSTRACT:This essay explores a more inclusive and equitable interpretation of "religion" within the context of religious vaccine exemptions. The existing literature critiques the prevalent interpretation of the meaning of religion in religious exemption cases, but frequently overlooks the importance of incorporating the concept of "lived religion." This essay introduces the concept of lived religion from religious studies, elucidates why this lived religion approach is crucial for redefining "religion," and illustrates its application in the domain of religious vaccine exemptions. The author (...) contends that broadening the meaning of religion by employing the concept of lived religion would promote a more inclusive and equitable implementation of religious vaccine exemptions.

ABSTRACT:Organismal superposition holds that the same individual both is and is not an organism, as a consequence of organismal pluralism. When coupled with the assumption that death is the cessation of an organism, this entails that there is no unique answer as to whether brain death is biological death. This essay argues that concerns about organismal pluralism and superposition do not undermine a theory of biological death, nor entail any metaphysical indeterminacy about the biological vital status of a brain-dead individual.

ABSTRACT:Psychedelics have again become a subject of widespread interest, owing to the reinvigoration of research into their traditional uses, possible medical applications, and social implications. As evidence for psychedelics' clinical potential mounts, the field has increasingly focused on searching for mechanisms to explain the effects of psychedelics and therapeutic efficacy of psychedelic-assisted therapy (PAT). This paper reviews three general frameworks that encompass several prominent models for understanding psychedelics' effects—specifically, neurobiological, psychological, and spiritual frameworks. Following our review, the implications of each (...) framework for ethics and professional competencies in the implementation of psychedelics as medicines are explored. We suggest that interdisciplinary education may be necessary to improve communication between researchers, develop models that effectively incorporate multiple levels of analysis, and facilitate collaboration between professionals with diverse backgrounds in the implementation of psychedelic medicines. We also address pitfalls associated with overemphasis on neuro-mechanisms, risks associated with instigating vulnerable states of consciousness, and hurdles associated with the integration of spiritual frameworks in medicine. Ultimately, as psychedelics push the boundaries of explanatory frameworks focused on one level of analysis, developing new and more useful models to reflect knowledge being produced in this field should be a central aim of psychedelic science going forward.

ABSTRACT:According to the mainstream bioethical stance, death constitutes the termination of an organism. This essay argues that such an understanding of death is inappropriate in the usual context of determining death, since it also has a social bearing. There are two reasons to justify this argument. First, the mainstream bioethical definition generates an organismal superposition challenge, according to which a given patient in a single physiological state might be both alive and dead, like Schrödinger's cat. Therefore, there is no clear (...) answer as to whether organ retrieval from a brain-dead patient is an act of killing or not. Second, when combined with the dead donor rule, the mainstream position in the definition of death might lead to ethically unacceptable verdicts, since there is a discrepancy between terminating an organism and depriving someone of moral status.

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. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Introduction to the Special Section on Psychedelics Research and TreatmentDominic SistiAgainst 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.Such "neuroreductionism" risks ignoring the subjective psychological and spiritual experiences of patients that appear to be pivotal in psychedelic-assisted therapy, often described as mystical and utterly transformative. At the psychological level, these substances engender a kind of vulnerability and suggestibility requiring clear ethical standards to ensure patients' psychological and physical safety. And so too, practitioners will need structural and cultural competency to recognize the spiritual or moral values that inspire patient reactions during and after their psychedelic experiences. Ethically informed psychedelic practitioners will have to navigate between disciplinary silos and explanatory models. One practical upshot is the open question of how best to train psychedelic practitioners who hold this broad set of competencies.To that end, well-trained practitioners will need to be able to disclose in some way the transformative properties of psychedelics to prepare patients for their experiences. But how does one describe the ineffable? This raises the question of how or if it is possible for patients to truly consent to the transformative experience elicited by psychedelics, often described as one of the most important experiences of a person's life. The experience might stimulate significant emotional healing, or it might be horrifying. This sounds like a problem uniquely attached to psychedelics: after all, most pharmaceuticals don't trigger changes in one's fundamental moral values, life choices, and commitments, nor are they intended to. Yet, Brent Kious, Andrew Peterson, and Amy McGuire challenge the view that the psychedelic experience is uniquely transformative and impervious to the disclosure requirements of informed consent, a bedrock of bioethics. Ultimately, the writers show how consent is possible even if the experiences are dramatically different from most medical interventions, endorsing a practical view of consent [End... (shrink)

ABSTRACT:Most medical learned societies have endorsed both "equivalence" between all forms of withholding or withdrawing treatment and the "discontinuity" between euthanasia and practices to withhold or withdraw treatment. While the latter are morally acceptable insofar as they consist in letting the patient die, the former constitutes an illegitimate act of actively interfering with a patient's life. The moral distinction between killing and letting die has been hotly debated both conceptually and empirically, most notably by experimental philosophers, with inconclusive results. This (...) article employs a "revisionary" intuititionist perspective to discuss the results of a clinical ethics study about intensivists' perceptions of withhold or withdraw decisions. The results show that practitioners' moral experience is at odds with both the discontinuity and equivalence theses. This outcome allows us to revisit certain concepts, such as intention and causal relationship, that are prominent in the conceptual debate. Intensivists also regard end-of-life decisions as being on a scale from least to most active, and whether they regard active forms of end-of-life decisions as ethically acceptable depends on the overarching professional values they endorse: the patient's best chances of survival, or the patient's quality of life.

ABSTRACT:The relationship between philosophy and bioethics remains a matter of perennial debate, but there does appear to be a consensus on one issue: whatever bioethics might want to borrow from philosophical ethics, it won't be normative theories. This essay argues that theories can have an important role to play in bioethics, though it might not be the one traditionally assumed by philosophers.
