After describing the disorder of psychopathy, I examine the theories and the evidence concerning the psychopaths’ deficient moral capacities. I first examine whether or not psychopaths can pass tests of moral knowledge. Most of the evidence suggests that they can. If there is a lack of moral understanding, then it has to be due to an incapacity that affects not their declarative knowledge of moral norms, but their deeper understanding of them. I then examine two suggestions: it is their deficient (...) practical reason or their stunted emotions that are at fault. The evidence supports both explanations. I conclude with an overview of the debate concerning whether they are morally or legally responsible for their actions. (shrink)

This is an attempt to propose the shift of bioethics from traditional and global levels up to the ‘cosmist personal’ —universal—level of considering the problems of individual's health. This approach in bioethics is likewise characterised as a health-centric and cosmist functional one. Substantially, this original bioethical approach relies on its own cosmological and ontological bases. Furthermore, novel bioethics needs its own realm of application—within the sphere of cosmist anthropology, which treats man as the bio-social-cosmist creature, but not merely a bio-social (...) one.

Most attempts to craft a definition of disease seem to have tackled two tasks simultaneously: 1) trying to create a series of inclusion and exclusion criteria that correspond to medical usage of the word disease and 2) using this definition to understand the essence of what disease is. The first task has been somewhat accomplished, but cannot reach closure because the concept of “disease” is based on a prototype, not a logical category. The second task cannot be accomplished by deduction, (...) but only by understanding how the body works and what each component is for, in evolutionary detail. An evolutionary view of the origins of the body and its vulnerabilities that result in disease provides an objective foundation for recognizing pathology. Our social definition of disease will remain contentious, however, because values vary, and because the label “disease” changes judgments about the moral status of people with various conditions, and their rights to medical and social resources.

In recent years, an increasing number of medical books and papers attempting to analyse the concepts of health and disease from the perspective of evolutionary biology have been published.This paper introduces the evolutionary approach to health and disease in an attempt to illuminate the premisses and the framework of Darwinian medicine. My primary aim is to analyse to what extent evolutionary theory provides for a biological definition of the concept of disease. This analysis reveals some important differences between functional explanations (...) in the field of evolutionary biology and functional explanations in the field of medicine. Moreover, I shall argue that the biological functions relevant to the health of an organism cannot be determined on the basis of evolutionary theory. Accordingly, it seems that Darwinian medicine does not provide for the definition of a biological concept of disease. Still,Darwinian medicine may suggest why we are susceptible to certain diseases; it might also prove a suggestive heuristic on the basis of which new hypotheses concerning relevant treatments of various diseases might be advanced.

The definitions and conceptualizations of health, and the management of healthcare have been challenged by the current global scenarios (e.g., new diseases, new geographical distribution of diseases, effects of climate change on health, etc.) and by the ongoing scholarship in humanities and science. In this paper we question the mainstream definition of health adopted by the WHO—‘a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity’ (WHO in Preamble to the constitution of (...) the World Health Organization as adopted by the international health conference, The World Health Organization, 1948)—and its role in providing tools to understand what health is in the contemporary context. More specifically, we argue that this context requires to take into account the role of the environment both in medical theory and in the healthcare practice. To do so, we analyse WHO documents dated 1984 and 1986 which define health as ‘coping with the environment’. We develop the idea of ‘coping with the environment’, by focusing on two cardinal concepts: adaptation in public health and adaptivity in philosophy of biology. We argue that the notions of adaptation and adaptivity can be of major benefit for the characterization of health, and have practical implications. We explore some of these implications by discussing two recent case studies of adaptivity in public health, which can be valuable to further develop adaptive strategies in the current pandemic scenario: community-centred care and microbiologically healthier buildings.

Human enhancement is ontologically, epistemologically, and ethically challenging and has stirred a wide range of scholarly and public debates. This article focuses on some conceptual issues with HE that have important ethical implications. In particular it scrutinizes how the concept of human enhancement relates to and challenges the concept of health. In order to do so, it addresses three specific questions: Q1. What do conceptions of HE say about health? Q2. Does HE challenge traditional conceptions of health? Q3. Do concepts (...) of health set limits to or direct HE? Addressing Q1 reveals that HE tends to frame and form our conception of health. Thereby it challenges traditional conceptions of health. Accordingly, health does not provide strong sources for setting limits to HE. On the contrary HE seems to define and expand the concept of health. Common to the concepts of HE and health is that both depend on vague value concepts, such as happiness, well-being, or goodness. There seems to be a tendency in the HE literature to define the goal of human life in terms of what is bigger, stronger, faster, more intelligent, and more resilient. However, this is confusing “goodness” with “more” and quality with quantity. Until HE more appropriately defines happiness, HE will fail to provide a relevant compass for improving the life of human beings. On the contrary, if we let simplified conceptions of “enhancement” come to define goodness or health, we may do more harm than good. Until doing so, we may well learn from Tithonus, listen to Douglas Adams’ Wowbagger, and pay attention to Virginia Woolf’s Orlando. Enhanced life may not be better. The same goes for health.

This essay replies to critics since 1995 of my “biostatistical theory” of health. According to the BST, a pathological condition is a state of statistically species-subnormal biological part-functional ability, relative to sex and age. Theoretical health, the total absence of pathological conditions, is then a value-free scientific notion. Recent critics offer a mixture of old and new objections to this analysis. Some new ones relate to choice of reference class, situation-specificity of function, common diseases and healthy populations, improvements in population (...) health, the practice of pathologists, “Cambridge changes” in health status, and comparative vs. absolute health concepts. I make no changes in doctrine, except to consider treating “normal aging” as pathological by taking young adults as the standard for all adults. (shrink)

Theorists of health have, to this point, focused exclusively on trying to define a state—health—that an organism might be in. I argue that they have overlooked the possibility of a comparativist theory of health, which would begin by defining a relation—healthier than—that holds between two organisms or two possible states of the same organism. I show that a comparativist approach to health has a number of attractive features, and has important implications for philosophers of medicine, bioethicists, health economists, and policy (...) makers.

Overdiagnosis and disease are related concepts. Widened conceptions of disease increase overdiagnosis and vice versa. This is partly because there is a close and complex relationship between disease and overdiagnosis. In order to address the problems with overdiagnosis, we may benefit from a closer understanding this relationship. Accordingly, the objective of this article is to elucidate the relationship between disease and overdiagnosis. To do so, the article starts with scrutinizing how overdiagnosis can explain the expansion of the concept of disease. (...) Then it investigates how definitions of disease address various challenges of overdiagnosis. The article specifically investigates recent attempts to clarify the relationship between the concepts of disease and overdiagnosis. Several shortcomings are identified and lead to a closer analysis of overdiagnosis in the diagnostic process. Contrary to recent contributions to the field, it is argued that cases of overdiagnosis are not cases of disease. They are non-verified labelling of disease. It is revealed how overdiagnosis establishes an unwarranted link between indicative phenomena, such as polyps or cell changes, and harm, and thereby generates a link to disease. One implication of this study is that we should stop attributing disease language to indicative phenomena. That is, we should stop calling it “cancer screening” when we are actually searching for polyps. Another implications is that we should strive for scientific progress in differentiating phenomena that are of negative value to us from those that are not. In overdiagnosis we diagnose something that is not disease: it is over-diagnosis. (shrink)

ZusammenfassungDer Krankheitsbegriff soll aus der Perspektive der klinischen Medizin am Beispiel der Radioonkologie dargestellt werden. Als theoretisches Modell zum ganzheitlichen Verständnis wird zunächst der interaktive Dualismus eingeführt. Danach wird die Interaktion zwischen Geist und Körper als wesentlich angesehen, um den Patienten mit Würde und Mitgefühl zu behandeln. Auch die Strahlentherapie erfordert nach ihrem Selbstverständnis einen ganzheitlichen Zugang zum Patienten. Demgegenüber zeigt die Analyse der aktuellen radioonkologischen Literatur einen reduktionistischen Krankheitsbegriff, der in erster Linie objektive Kriterien aus ärztlicher Sicht zur Definition (...) von Krankheit heranzieht. Im Dialog könnten stattdessen Arzt und Patient einen gemeinsamen Krankheitsbegriff entwickeln; hierbei finden im Sinne des interaktiven Dualismus gleichermaßen objektive ärztliche wie subjektive patientenbezogene Kriterien Berücksichtigung. Grenzen dieses neuen Konzepts erfordern eine besondere Beachtung und werden zuletzt erläutert. (shrink)

The concept of disease has been the subject ofa vast, vivid and versatile debate. Categoriessuch as ``realist'', ``nominalist'', ``ontologist'',``physiologist'', ``normativist'' and``descriptivist'' have been applied to classifydisease concepts. These categories refer tounderlying theoretical frameworks of thedebate. The objective of this review is toanalyse these frameworks. It is argued that thecategories applied in the debate refer toprofound philosophical issues, and that thecomplexity of the debate reflects thecomplexity of the concept itself: disease is acomplex concept, and does not easily lenditself to definition.

In this paper, I will argue that ageing can be construed as disease. First, the concept of disease is discussed, where the distinction is made between two lines of thought, an objectivist and a subjectivist one. After determining the disease conception to be used throughout the argument, it is proposed that senescence could be seen as disease. Three common counterarguments are discussed, none of which appears strong enough to effectively counter the advocated view. In the third section, two potential implications (...) of the view advocated here will be briefly touched upon. These are the quest for a cure or treatment for ageing and the general attitude towards the elderly. It is concluded that, utilizing an objective disease concept, ageing could be seen as a disease. None of the considered counterarguments packs enough of a punch to discard this. The implications are complex and intertwined, but need not be negative. (shrink)

This article claims that health promotion is best practised in the light of an Aristotelian conception of the good life for humans and of the place of health within it.

Although natural selection might be expected to reduce the incidence and severity of disease, disease persists. Natural selection leads to increases in the mean fitness of populations and so will reduce the frequency of disease-associated alleles, but other evolutionary processes, such as mutation and gene flow, may introduce or increase the frequency of these deleterious alleles. The pleiotropic actions of genes and the epistatic interactions between them complicate the relationship between genotype and phenotype, and may result in the preservation of (...) disease-associated alleles. Deleterious alleles may also be maintained because of linkage to beneficial alleles. The inability of natural selection to eliminate diseases of aging is a reminder that fitness – success in producing progeny, or in contributing genes to the population gene pool – is not equivalent to the absence of disease. Nutritional or psychosocial cues may lead to life history strategies that maximize survival to reproductive maturity at the expense of disease later in life. Natural selection acts on genes, cells, and groups, as well as on organisms; the outcome of evolution reflects selection at different levels of biological organization. Finally, the human environment is constantly changing, largely because of the evolution of our parasites and because of changes in cultural beliefs and practices; genetic evolution is comparatively slow and lags behind environmental change. An evolutionary nosology complements traditional medical nosologies and enhances our understanding of the persistence of disease and the meaning of human variation. (shrink)
