This article investigates five kinds of vagueness in medicine: disciplinary, ontological, conceptual, epistemic, and vagueness with respect to descriptive-prescriptive connections. First, medicine is a discipline with unclear borders, as it builds on a wide range of other disciplines and subjects. Second, medicine deals with many indistinct phenomena resulting in borderline cases. Third, medicine uses a variety of vague concepts, making it unclear which situations, conditions, and processes that fall under them. Fourth, medicine is based on and produces uncertain knowledge and (...) evidence. Fifth, vagueness emerges in medicine as a result of a wide range of fact-value-interactions. The various kinds of vagueness in medicine can explain many of the basic challenges of modern medicine, such as overdiagnosis, underdiagnosis, and medicalization. Even more, it illustrates how complex and challenging the field of medicine is, but also how important contributions from the philosophy can be for the practice of medicine. By clarifying and, where possible, reducing or limiting vagueness, philosophy can help improving care. Reducing the various types of vagueness can improve clinical decision-making, informing individuals, and health policy making. (shrink)

What is it to be mentally healthy? In the ongoing movement to promote mental health, to reduce stigma, and to establish parity between mental and physical health, there is a clear enthusiasm about this concept and a recognition of its value in human life. However, it is often unclear what mental health means in all these efforts and whether there is a single concept underlying them. Sometimes, the initiatives for the sake of mental health are aimed just at reducing mental (...) illness, thus implicitly identifying mental health with the absence of diagnosable psychiatric disease. More ambitiously, there are high-profile proposals to adopt a positive definition, identifying mental health with psychic or even overall well-being. We argue against both: a definition of mental health as mere absence of mental illness is too thin, too undemanding, and too closely linked to psychiatric value judgments, while the definition in terms of well-being is too demanding and potentially oppressive. As a compromise, we sketch out a middle position. On this view, mental health is a primary good, that is, the psychological preconditions of pursuing any conception of the good life, including well-being, without being identical to well-being.

Anya Plutynski’s Explaining Cancer extends the insights of contemporary philosophy of biology to research on cancer and cancer treatment. Cancer is conceptualized as a complex process for which a pluralist theoretical approach is the most appropriate. This review essay explores implications for philosophy of science and cancer research.

In the traditional philosophical debate over different conceptual analyses of “disease,” it is often presupposed that “disease” is univocally definable and that there are clear boundaries which distinguish this univocal category “disease” from the category of “nondisease.” In this paper, I will argue for a shift in the discussion on the concept of “disease” and propose an alternative, pragmatic approach that is based on the conviction that “disease” is not a theoretical concept but a practical term. I develop a view (...) on which our use of the term “disease” is determined by two interacting factors, namely, value-laden considerations about the desirabilty of certain states and discoveries of cause which is/are explanatorily relevant. I show how these factors interact with regard to a taxonomy of kinds of diseases. This pragmatic approach will not lead me to a final definition of “disease,” but will result in a more realistic description of the way we build, use, apply, and change our concept of “disease.” Meanwhile, it is useful as a basis for critical reflection on disease-labeling in medicine.

Recently, concerns have been raised about the phenomenon of ‘overdiagnosis’, the diagnosis of a condition that is not causing harm, and will not come to cause harm. Along with practical, ethical, and scientific questions, overdiagnosis raises questions about our concept of disease. In this paper, we analyse overdiagnosis as an epistemic problem and show how it challenges many existing accounts of disease. In particular, it raises ques- tions about conceptual links drawn between disease and dysfunction, harm, and risk. We argue (...) that ‘disease’ should be considered a vague concept with a non-classical structure. On this view, overdiagnosed cases are ‘borderline’ cases of disease, falling in the zone between cases that are clearly disease, and cases that are clearly not disease. We then develop a pre ́cising definition of disease designed to provide practical help in preventing and limiting overdiagnosis. We argue that for this purpose, we can define disease as dysfunction that has a significant risk of causing severe harm to the patient. (shrink)

In this paper, we examine recent critiques of the debate about defining disease, which claim that its use of conceptual analysis embeds the problematic assumption that the concept is classically structured. These critiques suggest, instead, developing plural stipulative definitions. Although we substantially agree with these critiques, we resist their implication that no general definition of “disease” is possible. We offer an alternative, inductive argument that disease cannot be classically defined and that the best explanation for this is that the concept (...) is structured as a cluster. We further argue that we do not need to reject the possibility of defining the general concept “disease” to legitimate developing stipulative definitions of disease that are relative to particular purposes. A cluster definition of disease is compatible with contextually motivated definitions, which may be considered précisifications of the more general cluster concept. (shrink)

This thesis is about the notions of health and pathology in medical theory. I develop a theory, which defines ‘health’ and ‘pathology’ in a way that solves several problems with earlier suggestions of how to define these terms. I call the theory ‘the disposition profile efficiency theory’, abbreviated ‘the DPE-theory’. According to the DPE-theory, a trait token is healthy, roughly, if and only if all of its dispositions for performing physiological functions are efficient enough. A trait token is pathological, roughly, (...) if and only if at least one of its dispositions for performing a physiological function is not efficient enough. The notion of efficiency, I suggest, is reference class-relative: the efficiency of a trait token’s disposition for performing a physiological function expresses a relation between the trait token and a health standard for the trait token’s bearer’s reference class. The thesis also examines the most discussed theory of health and pathology, “the biostatistical theory” proposed by Boorse. Both the DPE-theory and the biostatistical theory are evaluated against a number of desiderata: the theory should be theoretically sound; only use empirical, statistical, and logical terms; not involve values; be clear; both account for health and pathology as reference class-relative properties, and account for the importance of integration of different physiological functions for health; and have reasonable implications. It is argued that the DPE-theory satisfies the desiderata, and that it does so better than the biostatistical theory. The main contributions of the thesis are the DPE-theory’s models of dispositions, its approach to defining reference classes, its efficiency measure, and its way of drawing the line between high enough efficiencies and too low efficiencies. Other important contributions concern the desideratum about reasonable implications. It is shown how the DPE-theory contributes to solving two much discussed objections directed towards the biostatistical theory, “the problem of common diseases” and “Kingma’s dilemma”. Further, the DPE-theory is used to illuminate discussions about certain types of conditions for which it is contested whether they should count as healthy or pathological. (shrink)

Science and technology have vastly expanded the realm of medicine. The numbers of and knowledge about diseases has greatly increased, and we can help more people in many more ways than ever before. At the same time, the extensive expansion has also augmented harms, professional responsibility, and ethical concerns. While these challenges have been studied from a wide range of perspectives, the problems prevail. This article adds value to previous analyses by identifying how the moral imperative of medicine has expanded (...) in three ways: (1) from targeting experienced phenomena, such as pain and suffering, to non-experienced phenomena (paraclinical signs and indicators); (2) from addressing present pain to potential future suffering; and (3) from reducing negative wellbeing (pain and suffering) to promoting positive wellbeing. These expansions create and aggravate problems in medicine: medicalization, overdiagnosis, overtreatment, risk aversion, stigmatization, and healthism. Moreover, they threaten to infringe ethical principles, to distract attention and responsibility from other competent agents and institutions, to enhance the power and responsibility of professionals, and to change the professional-beneficiary relationship. In order to find ways to manage the moral expansion of medicine, four traditional ways of setting limits are analyzed and dismissed. However, basic asymmetries in ethics suggest that it is more justified to address people’s negative wellbeing (pain and suffering) than their positive wellbeing. Moreover, differences in epistemology, indicate that it is less uncertain to address present pain and suffering than future wellbeing and happiness. Based on these insights the article concludes that the moral imperative of medicine has a gradient from pain and suffering to wellbeing and happiness, and from the present to the future. Hence, in general present pain and suffering have normative priority over future positive wellbeing. (shrink)

The article uses a producer-consumer theory from philosophy of mind and language to analyse the meaning of basic health concepts like disease, illness and sickness. The core idea of the producer-consumer perspective is that a person who has an incomplete understanding of a term can associate it with the same concept as a linguistic expert, if both of them are willing to defer to the same contextual or general norms of meaning. Using “disease” as an example, the article argues that (...) the producer-consumer theory implies that if patients were normally willing to defer to a standard expert concept of disease, it would be reasonable to assume that the concept of disease is this concept. However, it is empirically well documented that many patients are not willing to defer to health workers’ understanding of lay health concepts like “disease”. This means that the overall conceptual analysis of disease and other lay health concepts should be pluralistic—the concepts belong within what Wittgenstein calls different language-games. This conceptual pluralism is inconsistent with assumptions many theorists have made when attempting to develop general definitions of basic concepts of ill health. Furthermore, the pluralistic analysis has striking implications for how conceptions of meaning should be accepted as sound; participants in health discourses are entitled to use basic health terms like “health” and “illness” in accordance with their own language-games, and health workers should therefore acknowledge a diversity of meaning in patient communication. Nevertheless, health professionals can often secure a communicative platform of shared concepts by understanding patients’ language games, and by achieving contextual aims of agreement about meaning.

Hilary Putnam’s influential analysis of the ‘division of linguistic labour’ has a striking application in the area of doctor–patient interaction: patients typically think of themselves as consumers of technical medical terms in the sense that they normally defer to health professionals’ explanations of meaning. It is at the same time well documented that patients tend to think they are entitled to understand lay health terms like ‘sickness’ and ‘illness’ in ways that do not necessarily correspond to health professionals’ understanding. Drawing (...) on recent philosophical theories of concept possession, the article argues that this disparity between medical and lay vocabulary implies that it is, in an important range of cases, easier for doctors to create a communicative platform of shared concepts by using and explaining special medical expressions than by using common lay expressions. This conclusion is contrasted with the view that doctors and patients typically understand each other when they use lay vocabulary. Obviously, use of expressions like ‘sickness’ or ‘illness’ does not necessarily lead to poor communication, but it is important that doctors have an awareness of how patients interpret such terms.

New technologies facilitate the enhancement of a wide range of human dispositions, capacities, or abilities. While it is argued that we need to set limits to human enhancement, it is unclear where we should find resources to set such limits. Traditional routes for setting limits, such as referring to nature, the therapy-enhancement distinction, and the health-disease distinction, turn out to have some shortcomings. However, upon closer scrutiny the concept of enhancement is based on vague conceptions of what is to be (...) enhanced. Explaining why it is better to become older, stronger, and more intelligent presupposes a clear conception of goodness, which is seldom provided. In particular, the qualitative better is frequently confused with the quantitative more. We may therefore not need “external” measures for setting its limits – they are available in the concept of enhancement itself. While there may be shortcomings in traditional sources of limit setting to human enhancement, such as nature, therapy, and disease, such approaches may not be necessary. The specification-of-betterment problem inherent in the conception of human enhancement itself provides means to restrict its unwarranted proliferation. We only need to demand clear, sustainable, obtainable goals for enhancement that are based on evidence, and not on lofty speculations, hypes, analogies, or weak associations. Human enhancements that specify what will become better, and provide adequate evidence, are good and should be pursued. Others should not be accepted. (shrink)

This essay argues that what is central to Christopher Boorse’s biostatistical theory of disease as statistically subnormal part function (BST) are comparisons of the “functional efficiency” of parts and processes and that statistical considerations serve only to pick out a healthy level of functional efficiency. On this interpretation, the distinction between health and pathology is less important than comparisons of functional efficiency, which are entirely independent of statistical considerations. The clarifications or revisions of the BST that this essay offers are (...) friendly amendments that render moot some of the most prominent criticisms of Boorse’s account. (shrink)
