We seek to change the conversation about brain death by highlighting the distinction between brain death as a biological concept versus brain death as a legal status. The fact that brain death does not cohere with any biologically plausible definition of death has been known for decades. Nevertheless, this fact has not threatened the acceptance of brain death as a legal status that permits individuals to be treated as if they are dead. The similarities between “legally dead” and “legally blind” (...) demonstrate how we may legitimately choose bright-line legal definitions that do not cohere with biological reality. Not only does this distinction bring conceptual coherence to the conversation about brain death, but it has practical implications as well. Once brain death is recognized as a social construction not grounded in biological reality, we create the possibility of changing the social construction in ways that may better serve both organ donors and recipients alike.

In lieu of an abstract, here is a brief excerpt of the content:The Incoherence of Determining Death by Neurological Criteria: A Commentary on Controversies in the Determination of Death, A White Paper by the President’s Council on Bioethics*Franklin G. Miller** (bio) and Robert D. Truog (bio)Traditionally the cessation of breathing and heart beat has marked the passage from life to death. Shortly after death was determined, the body became a cold corpse, suitable for burial or cremation. Two technological (...) changes in the second half of the twentieth century prompted calls for a new, or at least expanded, definition of death: the development of intensive care medicine, especially the use of mechanical ventilators, and the advent of successful transplantation of vital organs. Patients with profound neurological damage, leaving them incapable of breathing on their own and in an irreversible coma, could be maintained for some period of time with the aid of mechanical ventilation. The situation of these patients posed two ethical questions. Is it appropriate to stop life-sustaining treatment? If so, is it acceptable to retrieve vital organs for transplantation to save the lives of others before stopping treatment?In 1968, the Ad Hoc Committee of the Harvard Medical School to Examine the Definition of Brain Death proposed that death could be determined on the basis of neurological criteria, thus providing a positive answer to these two questions (Ad Hoc Committee 1968). According to the position of this committee, patients diagnosed with the cessation of brain function are dead, despite the fact that they breathe and circulate blood with the aid of mechanical ventilation. [End Page 185] Because they are dead, it is appropriate, indeed imperative, to stop mechanical ventilation. And because they are dead, it becomes ethical to procure vital organs for transplantation before stopping what otherwise would be life-sustaining treatment. Remarkably, this innovative neurological determination of death became, with little debate or controversy, the established position in medical ethics and the law throughout the United States.The Harvard Committee articulated the diagnosis of “irreversible coma,” but merely asserted that this condition constituted death. No explanatory rationale was provided. It fell to the President’s Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research to provide an authoritative rationale in its 1981 report, Defining Death. The second paragraph of the report set the stage as follows: “The question addressed here is not inherently difficult or complicated. Simply, it is whether the law ought to recognize new means for establishing that the death of a human being has occurred” (President’s Commission 1981, p. 3). The Commission claimed that “death is a unitary phenomenon” (p. 7) and that the determination of death by neurological criteria, in terms of the absence of all brain function, is consistent with the traditional conception of death as the cessation of vital functioning of the organism as a whole. The key issue is the integrative functioning of the human organism, which ceases to exist, according to the Commission, when the whole brain, including higher cortical areas and the brain stem, fails to function. Although “brain-dead” patients do not appear to be dead—i.e., the reality of their death is “masked” by the activity of mechanical ventilation—the patient’s body has irreversibly lost all capacity for integrative functioning. In the words of the Commission: “When artificial means of support mask this loss of integration as measured by the old methods [cessation of respiration and heart beat], brain-oriented criteria and tests provide a new window on the same phenomenon” (p. 33). The President’s Commission was instrumental in developing and establishing “The Uniform Definition of Death Act”: “An individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead” (p. 2).Although the question posed by the President’s Commission was easy to articulate, the answer, over time, has proved complicated and controversial. The coherence and cogency of determining death by neurological criteria has been challenged. Various experts have demonstrated that “brain-dead” patients maintained on mechanical ventilation display a range of vital, integrative, functioning, which conflicts with the judgment that they are dead (Truog and...

This paper uses several case studies to suggest that (1) two prominent definitions of data do not on their own capture how scientists use data and (2) a novel perspectival account of data is needed. It then outlines some key features of what this account could look like. Those prominent views, the relational and representational, do not fully capture what data are and how they function in science. The representational view is insensitive to the scientific context in which data are (...) used. The relational account does not fully account for the empirical nature of data and how it is possible for data to be evidentially useful. The perspectival account surmounts these problems by accommodating a representational element to data. At the same time, data depend upon the epistemic context because they are the product of situated and informed judgements. (shrink)

Accepted medical practice already violates the dead donor rule. Explicitly jettisoning the rule—allowing vital organs to be extracted, under certain conditions, from living patients—is a radical change only at the conceptual level. But it would expand the pools of eligible organ donors.

Epistemic standards purport to tell us under what conditions we should adopt specific beliefs. In the scientific case, we might understand an epistemic standard as telling us what beliefs we should or even must adopt when faced with such-and-such evidence. It is an open question whether and to what extent science, or scientists, form beliefs based upon standards so construed. Epistemic relativism gives two strong arguments against a robust role for epistemic standards in science. This paper assesses these arguments and (...) argues that even if we accept them, epistemic standards play a strong, normative role and that failure to adhere to epistemic standards, in a sense to be clarified, risks irrationality. To make this argument, we must abandon the idea that standards determine in a strong sense what beliefs scientists must adopt and instead think of them as a guide for choosing between beliefs. If we think of standards in this way, then they can play a role in rational scientific discourse. This conception of standards is inspired by Kuhnian values and helps arbitrate between relativism and more rational conceptions of evidence and justification. The Chemical Revolution provides illustration of this view. (shrink)

Conventional medical ethics and the law draw a bright line distinguishing the permitted practice of withdrawing life-sustaining treatment from the forbidden practice of active euthanasia by means of a lethal injection. When clinicians justifiably withdraw life-sustaining treatment, they allow patients to die but do not cause, intend, or have moral responsibility for, the patient's death. In contrast, physicians unjustifiably kill patients whenever they intentionally administer a lethal dose of medication. We argue that the differential moral assessment of these two practices (...) is based on a series of moral fictions – motivated false beliefs that erroneously characterize withdrawing life-sustaining treatment in order to bring accepted end-of-life practices in line with the prevailing moral norm that doctors must never kill patients. When these moral fictions are exposed, it becomes apparent that conventional medical ethics relating to end-of-life decisions is radically mistaken. (shrink)

Controversies about the diagnosis and meaning of brain death have existed as long as the concept itself. Here we review the historical development of brain death, and then evaluate the various attempts to justify the claim that patients who are diagnosed as brain dead can be considered dead for all legal and social purposes, and especially with regard to procuring their vital organs for transplantation. While we agree with most commentators that death should be defined as the loss of integration (...) of the functioning of the organism as a whole, we conclude that patients diagnosed as brain dead have not, in fact, lost this integrated functioning. We close with reflections on the implications of this conclusion generally and particularly with regard to organ transplantation, and briefly make reference to alternative approaches to justifying the procurement of transplantable organs that do not depend upon a flawed approach to the diagnosis of death.

Perspectivism in Science Perspectivism, or perspectival realism, has been discussed in philosophy for many centuries, but as a view about science, it is a twenty-first-century topic. Although it has taken many forms and even though there is no agreed definition, perspectivism at its heart uses a visual metaphor to help us understand the scope and … Continue reading Perspectivism in Science →.

This paper uses scientific perspectivism as a lens for understanding acid experiments from the Chemical Revolution. I argue that this account has several advantages over several recent interpretations of this period, interpretations that do not neatly capture some of the historical experiments on acids. The perspectival view is distinctive in that it avoids discontinuity, allows for the rational resolution of disagreement, and is sensitive to the historical epistemic context.

The aim of this article is to use a model from the origin of life studies to provide some depth and detail to our understanding of exploratory models by suggesting that some of these models should be understood as indeterminate. Models that are indeterminate are a type of exploratory model and therefore have extensive potential and can prompt new lines of research. They are distinctive in that, given the current state of scientific understanding, we cannot specify how and where the (...) model will be useful in understanding the natural world: in this case, the origin of life on Earth. The purpose of introducing indeterminacy is to emphasize the epistemic uncertainty associated with modeling, a feature of this practice that has been under emphasized in the literature in favor of attempts to understand the more specific epistemic successes afforded by models.

This book challenges fundamental doctrines of established medical ethics. It is argued that the routine practice of stopping life support technology causes the death of patients and that donors of vital organs (hearts, liver, lungs, and both kidneys) are not really dead at the time that their organs are removed for life-saving transplantation. Although these practices are ethically legitimate, they are not compatible with traditional medical ethics: they conflict with the norms that doctors must not intentionally cause the death of (...) their patients and that vital organs can be obtained only from dead donors. The aim of this book is to undertake an ethical examination that aims to honestly face the reality of medical practices at the end of life. This involves exposing the misconception that stopping life support merely allows patients to die from their medical conditions, that there is an ethical bright line separating withdrawal of life support from active euthanasia, and that determination of death of hospitalized patients prior to vital organ donation is consistent with the established biological conception of death. A novel ethical justification is required for procuring vital organs from still-living donors. It is contended that in the context of plans to withdraw life support, donors of vital organs are not harmed or wronged by organ procurement prior to death, provided that valid consent is obtained for stopping treatment and organ donation. In view of serious practical difficulties in facing the truth regarding organ donation, an alternative pragmatic account is developed for justifying current practices that relies on the concept of transparent legal fictions. In sum, it is the thesis of this book that to preserve the legitimacy of end-of-life practices, we need to reconstruct medical ethics. (shrink)

Bioethics is a hybrid discipline. As a theoretical enterprise it stands for untrammeled inquiry and argument. Yet it aims to influence medical practice and policy. In this article we explore tensions between these two dimensions of bioethics and examine the merits and perils of a “Socratic” approach to bioethics that challenges “the conventional wisdom.”.

Drawing on a recent case report of a pregnant, brain‐dead woman who gave birth to a healthy child after over seven months of intensive care treatment, this essay rejects the established doctrine in medicine that brain death constitutes the biological death of the human being. The essay describes three policy options with respect to determination of death and vital organ transplantation in the case of patients who are irreversibly comatose but remain biologically alive.

Human life and death should be defined biologically. It is important not to conflate the definition of death with the criteria for when it has occurred. What is distinctively "human" from a scientific or normative perspective has nothing to do with what makes humans alive or dead. We are biological organisms, despite the fact that what is meaningful about human life is not defined in biological terms. Consequently, as in the rest of the realm of living beings, human beings die (...) when they no longer function biologically as organisms. In contrast, a determination of exactly when death has occurred, required to serve various social purposes, combines social and normative considerations with biological facts. (shrink)

Although informed consent is important in clinical research, questions persist regarding when it is necessary, what it requires, and how it should be obtained. The standard view in research ethics is that the function of informed consent is to respect individual autonomy. However, consent processes are multidimensional and serve other ethical functions as well. These functions deserve particular attention when barriers to consent exist. We argue that consent serves seven ethically important and conceptually distinct functions. The first four functions pertain (...) principally to individual participants: (1) providing transparency; (2) allowing control and authorization; (3) promoting concordance with participants' values; and (4) protecting and promoting welfare interests. Three other functions are systemic or policy focused: (5) promoting trust; (6) satisfying regulatory requirements; and (7) promoting integrity in research. Reframing consent around these functions can guide approaches to consent that are context sensitive and that maximize achievable goals. (shrink)

It now seems technically feasible to culture human embryos beyond the “fourteen‐day limit,” which has the potential to increase scientific understanding of human development and perhaps improve infertility treatments. The fourteen‐day limit was adopted as a compromise but subsequently has been considered an ethical line. Does it remain relevant in light of technological advances permitting embryo maturation beyond it? Should it be changed and, if so, how and why? What justifications would be necessary to expand the limit, particularly given that (...) doing so would violate some people's moral commitments regarding human embryos? Robust stakeholder engagement preceded adoption of the fourteen‐day limit and should arguably be part of efforts to reassess it. Such engagement could also consider the need for enhanced oversight of human embryo research. In the meantime, developing and implementing reliable oversight systems should help foster high‐quality research and public confidence in it. (shrink)
