Dominic Murphy, Concepts of Disease and Health, The Stanford Encyclopedia of Philosophy (Spring 2015), Edward N. Zalta (ed.)

Health and disease are critical concepts in bioethics with far-reaching social and political implications. For instance, any attempt to educate physicians or regulate heath insurance must employ some standards that can be used to assess whether people are ill or not. Concepts of health and disease also connect in interesting ways with issues about function and explanation in philosophy of the biomedical sciences, and theories of well-being in ethics.

Introduction

Doctors are called on to deal with many states of affairs. Not all of them, on any theory, are diseases. A doctor who prescribes contraceptives or performs an abortion is not treating a disease. Although some women cannot risk pregnancy or childbirth for health reasons, women typically use contraception or abortion in the service of autonomy and control over their lives. In addition, it is very difficult to find a philosophically or scientifically interesting cleavage between diseases and other complaints (Reznek 1987, 71–73).

One dominant strand in modern medicine sees a disease as essentially a process that recurs across individuals in slightly different forms: a disease is an abstract kind that is realized in different ways (Carter 2003: Whitbeck 1977). But since a disease is a biological insult, distinguishing it from injury is very difficult. Perhaps injuries are not processes in the relevant sense but events. This essay assumes that the conceptual issues raised by illnesses, injuries and other medical conditions are similar enough to let us put this demarcation problem aside. Disability is another important and neglected topic in health and well-being. It will be addressed here only slightly, since it would take us too far afield.

Health has received less philosophical attention than disease, and this essay will correspondingly have less to say about it. The conceptual terrain in the case of health is a little more complex than that of disease; one way of thinking about health says that it is just the absence of disease, so if disease is biological malfunction or abnormality, it follows that a healthy person is someone whose biological systems are all in order. But another way of looking at health insists that it is not just the absence of disease but the presence of something more; a positive state. The constitution of the World Health Organization (WHO) defines health “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity” (WHO 1948). According to views like this, we should think in terms not of health and disease alone, but in terms of health, disease and normality. This essay will look at theories of health after first discussing disease.

Naturalism and Constructivism

The tendency in recent philosophy has been to see disease concepts as involving empirical judgments about human physiology and normative judgments about human behavior or well-being (Bloomfield 2001, Boorse 1975, Ereshefsky 2009, Culver and Gert 1982, Thagard 1999). First, we have beliefs about the natural functioning of humans—both our common sense expectations about the body and scientific theories of human biology. Second, we make judgments about whether some particular condition or way of life is or is not undesirable, in some relevant way. This second set of concerns obviously involves normative criteria, to do with the extent to which a life is unnatural, undesirable or failing to flourish in some way. (There is not a clear consensus among writers here.) One important and controversial question is whether the judgments we make concerning our biology are also normative in some way. A further large question concerns the relationship between the two types of judgments, in both medicine and common sense.

Another strain in recent scholarship suggests that our normative judgments alone determine who falls under the concepts of health and disease. This view has been less influential in philosophy, but commands widespread adherence in other areas of the humanities and social sciences (e.g. Kennedy 1983, Brown 1990). Kitcher (1997, 208–9) summarizes the debate as follows:

Some scholars, objectivists about disease, think that there are facts about the human body on which the notion of disease is founded, and that those with a clear grasp of those facts would have no trouble drawing lines, even in the challenging cases. Their opponents, constructivists about disease, maintain that this is an illusion, that the disputed cases reveal how the values of different social groups conflict, rather than exposing any ignorance of facts, and that agreement is sometimes even produced because of universal acceptance of a system of values.

Kitcher's objectivism is more often called naturalism: I will provide a slightly more elaborate taxonomy of analyses of disease,starting with forms of constructivism and the difficulties they face will be discussed. Then naturalism will be similarly treated, before the discussion moves to health.

Kitcher's claim that an objectivist analysis, as he puts it, is “grounded” on facts about the human body is perhaps not as clear as it might be. Before arriving at some qualifications, then, we should have straightforward statements of naturalism and constructivism in hand. (Although, since the qualifications are not yet in place, perhaps no theorist would fully endorse these bald versions of the positions.)

The naturalist conception of disease (perhaps most clearly stated in Boorse 1975,1997) is that the human body comprises organ systems that have natural functions from which they can depart in many ways. Some of these departures from normal functioning are harmless or beneficial, but others are not. The latter are ‘diseases’. So to call something a disease involves both a claim about the abnormal functioning of some bodily system and a judgment that the resulting abnormality is a bad one. Naturalists contend that the determination of bodily malfunction is an objective matter to be determined by science. They may also argue (Boorse 1997) that determining whether a malfunction is detrimental to human well-being is also an objective matter, but often they concede that normative considerations are the basis for that judgment. So the naturalist position is that a disease is a bodily malfunction that causes one's life to deteriorate. This malfunction could take many forms: it is not a necessary part of the naturalist case that diseases constitute a natural kind.

Rather, they could be a set of naturally occurring processes that are held together in virtue of our interest in grouping them as a class. Kinds that work like this include “weed” or “vermin” (Murphy 2006): the existence of the superordinate class depends on human interests but the subordinate members are natural kinds whose natures can be investigated scientifically.

Constructivism, however, argues that human interests do not just define the superordinate class of diseases. It is human interests, not biological malfunctions, that explain the judgments that subordinate members have the relevant biological character. Although constructivists accept that disease categories refer to known or unknown biological processes they deny that these processes can be identified independently of human values by, for example, a science of normal human nature. Constructivist conceptions of disease are normative through and through, although the precise account of the relevant norms will vary between scholars.

The key constructivist contention is that there is no natural, objectively definable set of human malfunctions that cause disease. Rather, constructivists assert that to call a condition a disease is to make a judgment that someone in that condition is undergoing a specific kind of harm that we explain in terms of bodily processes. But the bodily processes are not objectively malfunctioning; rather, they are merely judged by us to be unusual or abnormal because they depart from some shared, usually culturally specific, conception of human nature. The crucial difference between the positions then is that for naturalists, diseases are objectively malfunctioning biological processes that cause harms. For constructivists, diseases are harms that we blame on some biological process because it causes the harm, not because it is objectively dysfunctional.

However, constructivism is hard to define satisfactorily, for two reasons. First, its core claim is a denial of the naturalist thesis that disease necessarily involves bodily malfunction. Since there are many views one might hold about the nature of the biological processes involved in disease that are compatible with the denial of malfunction, the positive constructivist claim varies across theories and is often elusive. Reznek (1987) for example, explicitly denies that malfunction is a necessary condition for disease. He does assert (ch 9) that diseases involve “abnormal” bodily processes, but he does not say what that means. Constructivists often, as we will see later, argue that disease judgments appeal to biological processes that are to be understood in terms of human practices rather than membership in some biologically definable class of abnormalities or malfunctions. We have decided that some harmful conditions are the province of the medical profession, and those are diseases.

That brings up the second reason why constructivism can be an elusive target: it has often rested on (perfectly reasonable) claims about the role that value judgments have played in medical practice, or on the prevalence of culturally specific disagreements about abnormal human behavior or physiology. This means, as we shall see, that constructivists, especially in the social sciences, do not tend to offer necessary and sufficient conditions. Rather, they often seek to reconstruct the concept of disease as revealed by our practices. Constructivism, therefore, often looks like a thesis about how inquiry is carried on: first we identify a condition we disvalue, then we look for a biological process that causes it and say that, whatever it is, it is abnormal. This stress on our practices is a common constructivist trope, whereas objectivists more often seek to analyse a concept that will clarify what disease really is, however fumbling and biased our attempts to uncover it may have been.

That both medical practice and lay thought shape disease concepts is undeniable. Because of this, we need to introduce a second distinction. Both naturalism and constructivism can take either a revisionist or a conservative form. A conservative view says that our folk concept of illness should constrain a theoretical picture of health and disease worked out by scientists and clinicians. A revisionist thinks that our existing concepts should be amended in the light of what inquiry uncovers. One could be a conservative or revisionist naturalist, as well as a conservative or revisionist constructivist.

Health and disease, like many other concepts, are neither purely scientific nor exclusively a part of common sense. They have a home in both scientific theories and everyday thought. That raises a problem for any philosophical account: suppose we try to say what health and disease really amount to, from which it follows that the scientific concept should fit the facts about world. If the picture we end up with deviates too far from folk thought, should we worry? You might think that everyday language puts constraints on a concept of health that need to respected, and that if we move too far from ordinary usage we have stopped talking about health and started talking about something else. Furthermore, it is not really possible to argue that scientific and vernacular uses of the concepts are fully independent, since the development of science influences everyday thought, and many scientific concepts begin in pre-scientific contexts and carry the marks of those origins deep into their careers.

Although there is a thriving body of work that tries to analyse the concept of disease – as we'll see in a moment – other theorists dispute the prospects for a successful analysis of the concept of disease. Schwartz (2007) contends that the biomedical sciences do not share a general concept of disease that is coherent enough to be analyzed. He recommends seeing the proposed analyses as introducing new concepts of disease that are related to existing usage but not bound by it. Concepts so introduced may work in some concepts but not others, and different concepts of disease could be needed for different medical purposes. Hesslow (1993) argues that diseases are not interesting theoretical entities in medicine and are irrelevant to most clinical decisions. These focus on how to improve a patient's condition and do not need to depend on a judgment of disease.

Furthermore, the concept of disease that is currently employed in most areas of medicine has undergone a process of development. For much of the modern era there has been a dialectic between two concepts of disease. On the one hand, there has been the idea that a disease is just an observable suite of symptoms with a predictable course unfolding. This notion dates back to Sydenham in the late seventeenth century. Kraepelin applied it to psychiatry as the basis for differential diagnosis, for example between hebephrenia and dementia praecox (schizophrenia) (1899, 173–175). The approach was supplanted as medicine matured by the concept of diseases as destructive processes in bodily organs which “divert part of the substance of the individual from the actions which are natural to the species to another kind of action” (Snow 1853, 155; for discussion see Whitbeck 1977, Carter 2003, Broome 2006). This is perhaps still the core medical conception of disease. It seeks explanations that cite pathological processes in bodily systems. More recent medicine has tended to weaken this slightly by adopting what Green (2007, ch, 2) calls an ‘actuarial’ model of disease. This model takes the presence of elevated risk, for example as indicated by high blood pressure, to be a disease even in the absence of overt symptoms or a clearly destructive pathological process.

Medicine recognizes illnesses like hypertension and Cushing's disease that are the outcome of systems in a poorly regulated state that is stable, albeit suboptimal. The idea of a specific pathogenic process in medicine includes dysregulation, but this may not accord with folk thought.

Modern medicine looks naturalistic about disease. One question, then, concerns the extent to which common sense and biomedical concepts are related. Perhaps both have naturalist commitments, or perhaps common sense is driven by values and medicine is not, or perhaps physicians are really constructivists who are self-deceived or arguing in bad faith.

There is little reason to expect scientific and common sense concepts to agree in general, so if medicine and everyday thought disagree about disease, we may ask which concept should be adopted. If we wish to distil a concept that can play a role in medical inquiry, we may side with the scientists. But such proposals, which argue for a sharp separation between scientific and folk uses, are not neutral pieces of observation about the language. They are proposals for purging science from commonsense constraints that hinder its development. A revisionist view of this sort, in this case, says that our concepts of health and disease might be a necessary starting point but should not constrain where the inquiry ends up. Other forms of revisionism are possible. A revisionist naturalist argues that we should follow the science where it takes us and come up with concepts that further scientific inquiry, for example, even if that means that we eventually use the language in ways that look bizarre from the standpoint of current common sense. But a revisionist constructivist could argue that our thought, whether medical or lay, should be reformed in the service of other goals, such as emancipation for hitherto oppressed groups. Such revisionist thought was important in overturning the psychiatric view, dominant until the 1970s, that homosexuality is a mental illness. Activists argued that homosexuality was diagnosed for offensive moral reasons and not for medical ones and the classification of homosexuality as a disease was changed as a result of lobbying on moral grounds rather than on the basis of any new discovery. Naturalists will respond that this was not an example of using constructivism for emancipatory ends, but of bringing psychiatrists to understand that they were not obeying their own naturalist principles about mental disorder, and showing them that there was no good reason to retain the diagnosis. Much debate between naturalists and constructivists involves competing histories in just this way. Constructivists strive to uncover the role that moral and social values have always played in medical diagnosis and argue that our disease categories are hence not properly naturalistic. Naturalists, though they must concede that many diagnoses have been based on moral values that we would now renounce, still insist that the concept of disease, when correctly applied, as it often is, is thoroughly naturalistic and not impugned by past failures by the medical profession to live up to its own scientific ambitions.

Naturalists tend towards conceptual conservatism. They typically appeal to our intuitions about illness as support for their own emphasis on underlying bodily malfunction. This assumes that our current concept is in good shape, that common sense and medicine share a concept of disease, and that medicine should respect lay intuitions about what is or is not a disease. Like many philosophers who think about other concepts with both scientific and common sense uses, conservative naturalists about disease think that folk concepts specify what counts as health and disease. The job of medicine is to look at the world and see if anything in nature falls under the concept as revealed by analysis (cf the “Canberra plan” of Jackson 1998) For revisionists, this understanding of common sense's in its relation to science is needlessly submissive to folk intuitions.

Revisionist naturalists argue that facts about physiological and psychological functioning, like other biological facts, obtain independently of human conceptions of the world. Our intuitions might tell us that a condition is not a disease. But scientific inquiry might conclude that people with the condition are really suffering from a biological malfunction. In that case, a conservative would recommend finessing the analysis to ensure that the concept of disease does not cover this case. A revisionist would say that we must bite the bullet and judge that this case falls under the concept even if that judgment is counterintuitive. A revisionist naturalist regards health and disease as features of the world to be discovered by biomedical investigation, and therefore loosely constrained, at best, by our everyday concepts of health and disease. Lemoine (2013) argues that conceptual analysis always involves a stipulative element concerning controversial or borderline cases. Because contending parties will be led by their intuitions to see different stipulations as reasonable, conceptual analysis will be very unlikely to decide between competing analyses that are all reasonably successful at capturing core cases. He suggests that instead philosophers should aim to naturalize disease by trying to first understand general features of theories in the medical sciences and then looking for perspicuous and coherent accounts of different disease types, with a view to eventually establishing an overall picture of the role disease thinking plays in medicine. This approach treats diseases as putative natural kinds and could be highly revisionist, while also leaving open the possibility that some diagnoses represent contingent historical outcomes that have left us with an incoherent category. Lange (2007) starts his account of disease from a similar impulse, insisting that diseases play an absolutely essential role in explaining a patient's symptoms. He argues that this explanatory role is characteristic of natural kinds elsewhere in science, and warrants thinking of diseases as natural kinds. Lange views diseases as natural kinds of incapacities.

Constructivists are usually revisionists. They tend to say that concepts of health and disease medicalize behavior that breaks norms or fails in some way to accord with our values; we don't like pain, so painful states count as diseases: we don't like fat people or drunks, so obesity and alcoholism count as diseases. Constructivists will often make this case with special vigor when it comes to mental disorder.

Constructivists are often social scientists and their interests may not map neatly on to philosophical concerns. They are not usually interested in conceptual analysis so much as in tracing the social processes by which categories are formulated and changed over time. Conrad (2007, 7–8), for example, says he is “not interested in adjudicating whether any particular problem is really a medical problem… I am interested in the social underpinnings of this expansion of medical jurisdiction”.

But constructivists often present their theories as unmasking common sense or medical conceptions of disease, and hence as a kind of revisionism. They may accept that diagnoses of ill-health involve objective facts that people appeal to, or presume that they can appeal to, when they say that somebody is sick. The assumption might be that germs or other medically relevant causal factors are present in a person and have given rise to visible phenomena that indicate ill-health. But a constructivist will claim that the actual, often unacknowledged, judgments driving the initial assertion that someone is unhealthy are derived from social norms. We may discover facts about obesity and its relationship to blood pressure or life expectancy. But the constructivist says that our search for the relevant biological findings is undertaken because we have already decided that fat people are disgusting and we are trying to find a set of medically significant properties in order to make our wish to stigmatize them look like a medical decision rather than a moral or aesthetic one. The crucial constructivist claim is that we look for the biological facts that ground disease judgments selectively, based on prior condemnations of some people and not others. Because they claim that social norms rather than disinterested inquiry drive medicine (and especially, psychiatry), constructivists tend to be revisionists about folk concepts, seeking to bring to light the unacknowledged sources of our concepts of health and disease. But constructivism could be a conservative view, aimed at uncovering our folk theory of health and disease. A constructivist who takes this view says that our folk concept of disease is that of a pattern of behavior or bodily activity that violates social norms.

One could be a constructivist about some diseases, and a naturalist about others. For example, one could be a naturalist about bodily disease but a constructivist about psychiatry. Thomas Szasz (1960, 1973, 1987), for instance, is usually read as a constructivist who denies that mental illness exists. But in fact Szasz has a very strict objectivist concept of disease as no more than damage to bodily structures.

He argues that mental disorders cannot exist because they are not the result of tissue damage. He is a naturalist about disease, which leads him to deny that mental illness is real and to offer a constructivist and revisionist analysis of our psychiatric practices. And indeed claims that we are merely taking conduct we don't like and calling it pathological are more plausible in psychiatry than in other parts of medicine, since there is a long history of psychiatrists who have done just that. Samuel Cartwright argued in 1843 that American slaves who tried to escape were afflicted with “drapetomania” or the “disease causing slaves to run away” (Cartwright 2004, 33); slaves were also found uniquely prone to “dyesthaesia Aethiopica”, which made them neglect the property rights of their masters (Brown 1990). Nineteenth century physicians regularly practiced cliterodectomy to cure women of sexual desire, which everybody knew never afflicted normal females of good family (Reznek 1987, 5–6). More recently, Soviet psychiatrists found that political dissidents suffered from “sluggish schizophrenia”. And Horwitz and Wakefield (2007) have suggested that depression has been severely overdiagnosed by recent generations of American psychiatrists, leading to the pathologizing of ordinary sadness.

Our current taxonomy of illness could involve both naturalist intuitions about some conditions and constructivist rationalizations about others. You could use this depiction of everyday thought as a premise in an argument for revisionism, on the grounds that our folk concepts are too confused to serve as constraints (Murphy 2006 makes this argument with respect to psychiatry).

Problems for Constructivism

Constructivism seems correct about some diseases; that is, societies have at times thought that some human activities were pathological because of values rather than scientific evidence. However, it is another task to show that constructivism is correct about our concept of disease. And this would be true even if there were no diseases; it might still be the case that our concept of disorder is naturalist even if nothing falls under it. There are no unicorns, but an analysis of the concept of unicorn that says that unicorns are giant purple cows that live on human flesh would be a faulty analysis all the same.

The chief problem for constructivism is that we routinely make a distinction between the sick and the deviant, or between pathological conditions and those that we just disapprove of. Our disease concepts cannot just be matter of disvaluing certain people or their properties. It must involve a reason for disvaluing them in a medical way rather than some other way. Illness has never been the only way to be deviant. So Szasz is just wrong to claim that “when a person does something bad, like shoot the president, it is immediately assumed that he might be mad” (1974, 91). Most of the time when people do bad things nobody doubts their sanity, just their morals. Physically or mentally ill people, even if they are seen as norm-breakers, are seen as a distinctive class of norm-breakers. What's distinctive about them?

The problem is that we routinely judge that people are worse off without thinking they are ill in any way—for example, the ugly, the poor, people with no sense of humor or lousy taste or a propensity for destructive relationships. We don't treat these judgments of comparative disadvantage as a prelude to medical inquiry, so why do we do so in some other cases?

Notice that the problem is not just one of establishing that someone is badly off or is in some other disvalued state. Rather, the trouble is caused by the requirement that someone is badly off in a specific, health-related or medically significant way. Rachel Cooper, for example (2002, 272–74), analyzes the concept of disease as a bad thing to have that is judged to require medical attention. She deals with the objection that specifying when someone is badly off is very difficult. Cooper admits that it is a hard problem, but replies that it is a widespread problem, one which crops up in many areas of moral philosophy.

This response is correct as a general point but does not touch the present objection. The objection is not that it is hard to say when someone is badly off, but that it is hard to isolate the specific class of ways of being badly off that we regard as medically relevant without relying on a notion of natural malfunction.

John Harris, for example, posits an “ER test” (2007, 91) according to which we can think of a disorder as a condition that makes someone worse off and is such that emergency room personnel would be negligent if they did not remedy it if they could. But as it stands the ER test is much too broad. Taken literally the ER tests requires medical personnel to teach the local language to immigrants whose lives are worsened by a lack of competence in it. A general theory of ill-being would be as desirable as a theory of well-being. But without further elaboration it would not discriminate between medical and non-medical forms of ill-being. Cooper and Harris face the difficulty of specifying what is distinctively medical about the conditions that we expect medical personnel to treat: of course, a thesis about what counts as a medical intervention that was put in terms of combating disease or pathology would be circular. Reznek (1987, 163) argues that we can delimit a purely medical sphere “enumeratively without reference to the concept of disease—in terms of pharmacological and surgical interventions.” However, as we saw at the start of this essay, a lot of medical attention is directed at conditions which we do not call diseases. Prescribing contraceptive pills is a pharmacological intervention, but it is not directed against a disease; going on the pill is not like beginning a course of anti-malarial tablets.

The naturalist answer to the question what makes some medical interventions directed against disease is that conditions which doctors treat are diseases in so far as they involve natural malfunctions. The constructivist view is that the class of what we call malfunctions is picked out by its involvement in medical practice, and not the other way round. Cooper and Harris try to base their analysis on our practices, but they are unable to distinguish medical practices from non-medical ones.

The constructivist needs to explain why the value judgments that we direct at putative sick people form a special class of value judgments. And that explanation has to show, in addition, why we think the conditions that we single out as diseases with those special value judgments are candidates for a particular set of causal explanations. It's all very well to point out, as Reznek does (p.88) that an etiology only explains a pathology if we have already decided that it is a pathology. This is correct, but it dodges the conceptual question of why we first decide that only some people or conditions are pathological. The naturalist says this: we think some people are worse off because of a special kind of causal process, namely a disturbance of normal physical or psychological function. It is that causal judgment that has conceptual priority, even if, as a matter of timing, the violation of a norm is what is detected first. Note that it does not refute naturalism to point out that the concept of disease is sometimes misapplied, so that we think people are sick but discover that they are not. In such cases (e.g. homosexuality) the explanation for why it happened may be that our values caused the initial judgment, but that does not show that the concept of disease is constructivist, rather than naturalist. No concept is correctly applied every time.

Reznek, for instance, argues that to judge “that homosexuality is a disease we first have to make a value-judgment. We have first to judge that we would be worse off being homosexual” (1987, 212). Reznek then says that we could discover that homosexuality is not a disease if we find out that it develops by a normal psychological process. Reznek calls this is a form of constructivism (or normativism, in his terms) because value judgments have conceptual priority: but in fact in the case he describes it seems that value judgments are actually only heuristics, drawing our attention to whether something might be wrong with someone. If the initial judgment can be overturned by a biological discovery, then it seems that biological facts are necessary for a final judgment. That is to say that our concept of disease necessarily involves both biological and evaluative judgments. That is a version of naturalism, since the biological facts are the ultimate foundation for the judgment. Indeed, naturalism seems to explain why constructivist interpretations are sometimes correct. We say now that homosexuality was never a disease, and was just diagnosed on moral grounds, because it was not caused by malfunctions according to any even moderately correct theory of human biology or psychology. Values stopped people from getting the science right, but homosexuality was correctly understood, and no longer seen as a disease, when the science was done in a properly disinterested way.

Naturalism embodies the important insight that we do in fact think that disease involves a causal process that includes biological abnormalities. It does not mean, however, that all diseases have to receive the same biological explanation. The class of diseases will include a variety of different conditions that receive different causal explanations. That is, even if diseases are natural kinds, the superordinate category of disease may not be. Not just any sort of story about the causes of abnormal behavior will do, and it is difficult to reach a satisfactory specification of the sorts of causes that common sense might recognize. We also distinguish, based on our common sense understanding of human biology, between pathological and non-pathological versions of the same outward phenomena. Because aging is normal we acknowledge that an elderly person will differ from a young adult, so our assumptions about normality are sensitive to background conditions. But when aging is abnormal, we call it a disease. Hutchinson-Gilford progeria syndrome, for instance, causes children to undergo all the stages of human aging at a bizarrely accelerated rate. They nearly always die by seventeen, far gone in senescence. Even though we don't know much about it, we think of Hutchinson-Gilford as a disease not just because we don't like being old but because we think it is different from getting old in a way that must be caused by some underlying pathology. The concept of disease necessarily requires, just as naturalism insists, that a condition have a causal history involving abnormal biological systems. So let's turn to naturalism, and see whether it should be a conservative or revisionist position.

Naturalism

Forms of Naturalism

When we have decided that someone's biological systems do not function properly, we still face the question, how should we think about that person's condition? Naturalists usually admit that there is more to the concept of disease than biological malfunction even if they think that biological malfunction is a necessary condition for disease. This involves a two-stage picture (Murphy 2006, ch 2) which inverts the constructivist portrayal of our practice. Naturalists who buy the two stage picture think that, first, we agree on the biological facts about malfunction. At the second stage we make the normative judgment that the person with the malfunction is suffering in some way. (This is the order of conceptual priority, not the chronological sequence in which judgments are made.) Spitzer and Endicott (1978, 18) for example, say that disease categories are “calls to action”; assertions that something has gone wrong within a person's body in a way that produces consequences we think we need to remedy (see also Papineau 1994).

Normative considerations, on this account, inform our judgments about disease but do not have the conceptual priority accorded them by constructivists. We make judgments that someone is suffering in ways we associate with inner malfunction. We also see people who are suffering but who we don't think are ill or injured, because we do not regard their bodily dysfunction as symptoms of disease: vaccination, surgical incisions, ear-piercing or childbirth are examples. Or imagine a skin condition that in some cultures causes the sufferer to be worshiped as a god, or become a sought-after sexual partner. The two-stage picture is designed to distinguish between the physical abnormality and the difference it makes to the life of the person who has it. The idea is that whether someone's body is not functioning correctly is a separate question from whether it is bad to be like that.

The second stage, the question about whether life is worsened by a malfunction, is omitted by simple naturalism. Simple naturalists say that all there is to disease is the failure of someone's physiology (or psychology) to work normally. The view has few adherents, but as noted above, Szasz (1987) uses simple objectivism about disease to justify his claims that mental disorder is a myth.

Specifying Causes

We have arrived at a generic naturalism that says judgments of illness are sensitive to causal antecedents of the right sort, as well as to value judgments about the effects of those causes. What are the right causal antecedents? Culver and Gert's (1982) requirement that the antecedents be a “nondistinct sustaining cause” is a biologically noncommittal criterion. Culver and Gert analyze the concept of a malady, which involves suffering evils, or increased risk of evil, due to “a condition not sustained by something distinct” from oneself (1982, 72). The cause can be physical or mental, (p.87), provided it is a sustaining cause that is not distinct from the sufferer (p.88). A wrestler's hammerlock, because its effects come and go with the presence or absence of the cause itself, is an example of a sustaining cause. But because the wrestler is a distinct entity from the sufferer, someone in a hammerlock does not have a malady. If the cause is inside the body it is nondistinct just in case it is difficult to remove (e.g. a surgical implement left behind in the body) or it is biologically integrated in the body (e.g. a retrovirus). This is an attractively simple solution but it is too inclusive. Culver and Gert (p.71) say that loss of freedom, opportunity or pleasure count as evils. But if that is so, then black citizens of South Africa and Mississippi (among many other places) used to suffer from maladies, since they were unfree, unhappy and oppressed. And they suffered these evils because of black skin, which was a nondistinct sustaining aspect of their nature. But it wasn't a disease. Of course, the presence of racism, backed up by coercive social structures, was also necessary, but aspects of the environment are implicated in many maladies.

This counterexample is instructive, however, since there are two ways of amending the proposal in the light of it. First, perhaps the principle of nondistinct sustaining causes fails to capture our intuitions about causes of disease. A second possibility is that the principle is a good causal condition, but that the account of evils is too broad, and needs to be restricted to a more intuitively medical set of evils, rather than the broader class of impediments to well-being. The section on health will go over the terrain that's relevant for the second option; the current discussion is about the causal condition. Boorse (1975, 1976, 1977, 1997) and his followers have opted for a more restrictive view of the causes of disease. They contend that disease necessarily involves biological malfunction. Boorse distinguished “disease” from “illness”. The former is the failure to conform to the “species-typical design” of humans, and the latter is a matter of judgments that a disease is undesirable, entitles one to special treatment, or excuses bad behavior. An account of malfunction must be parasitic on a theory of function. Boorse thinks a function is a ‘species-typical’ contribution to survival and reproduction (1976, 62–63). Disease is failure to function according to a species design, in which functional efficiency is either degraded below the typical level or limited by environmental agents (1977, 550, 555, 567; 1997, 32). Boorse understands this as functioning “more than a certain distance below the population mean” (1977, 559) for the relevant set of humans. (Since not all members of a species have the same design in every respect, we need to specify reference classes according to biologically relevant subgroups.) This cutoff point, he thinks, can only be specified as a matter of convention, but this conventional element does not threaten the objectivity of diagnoses. Responses to Boorse since the original theory was formulated have concentrated on two issues. First is the apparent existence of states like tooth decay that are widespread, so apparently statistically normal, yet definitely pathologies. The second is the“line-drawing problem” Schwartz (2007) which comes in two related guises: how we are to reference classes and how we can distinguish between normal and abnormal levels of functional efficiency.

Boorse's position has been very influential and shaped the entire recent literature. In psychiatry, for instance, Wakefield (1992, 1997a, 1997b), follows Boorse (1976) in assuming that humans have a species-typical design, which he assumes is a product of natural selection. Wakefield applies the picture to both mental and physical illness: first, we judge that a psychological mechanism is not performing the function for which natural selection designed it; second, we judge that the malfunction is harmful. An appeal to natural function, by adding extra commitments to the idea of a cause of illness, rules out skin pigment as a cause of evil.

Cooper (2002, 265) suggests that a straightforward appeal to dysfunction must be qualified in light of some apparent counterexamples. A woman taking contraceptive pills, for example, may be interfering with typical functioning, but ingesting contraceptives is not a disease. (Boorse would have to call it a self-inflicted disease that does not make the woman ill.) Cooper also raises the problem of individuals with chronic conditions that are controlled by drugs. She argues that these are cases of diseased subjects who nonetheless function normally and suggests that the analysis must be amended to talk of a disposition to malfunction. But, as Cooper sees, the big problem faced by Boorsian accounts is that of coming up with an acceptable conception of normal function in the first place.

Functions

The Boorsian analysis is of a commonsense concept of disease which bottoms out in a notion of malfunction as the cause of illness. The view is that conceptual analysis determines the empirical commitments of our disease concepts and then hands over to the biomedical sciences the problem of finding biological functions and malfunctions. Some recent theorists, notably Wakefield, have argued for an evolutionary account of function as that which has historically been spread by natural selection. This stress on a distinctively evolutionary account of function is unattractive, since the biomedical sciences seem to employ a different conception of function. Two other problems affect the whole naturalist community. A reliance on scientific, functional decomposition as the ultimate justification of judgments of health and disease requires a revisionist, rather than a conservative, account. Also, it may not always be possible to settle contested cases by an appeal to a notion of normal human nature, because that notion is itself contested.

First, why suppose that the relevant concept of function is an adaptive one, and that dysfunction is a failure of a biological system to fulfill its adaptive function? This analysis of function is often termed the etiological account, and although it is widespread in philosophy of biology it seems to be conceptually tied to fitness rather than health (Methot 2011). Advocates of a thoroughgoing evolutionary approach to medicine (such as Gluckman, Beedle and Hanson 2009) can be read as providing a framework within which we can make sense of a number of processes that have an effect on health and disease, but not as offering analyses of health and disease that are tied to fitness. Gluckman et al. (p.5) consider the difference between lactose intolerance, which develops after weaning and is normal for most human populations, and congenital hypolactasia, a condition in which newborns cannot digest maternal milk. The former is a consequence of the absence of pastoralism in most historical human populations and does not affect fitness in those populations, whereas the latter would have been fatal in the past and thus was selected against. However, they do not define disease in terms of fitness-lowering: they note rather that an evolutionary perspective can make us sensitive to hitherto neglected causes of pathology and also sensitive to over-hasty judgments of pathology in cases where the condition is normal among populations with a given evolutionary trajectory.

Wakefield's approach is not that of throughgoing evolutionary theorist of disease. Rather, he plugs an etiological account of function into a Boorsian model, and his approach has been developed with little attempt to argue that medicine does in fact use an evolutionary, teleological account of function. In opposition, Schaffner (1993) has argued very convincingly that although medicine might use teleological talk in its attempts to develop a mechanistic picture of how humans work, the teleology is just heuristic. It can be completely dispensed with when the mechanistic explanation of a given organ or process is complete. Schaffner argues that as we learn more about the causal role a structure plays in the overall functioning of the organism, the need for teleological talk of any kind drops out and is superseded by the vocabulary of mechanistic explanation, and that evolutionary functional ascriptions are merely heuristic; they focus our attention on “entities that satisfy the secondary [i.e. mechanistic] sense of function and that it is important for us to know more about” (1993, 390).

In effect, Schaffner is arguing that the biomedical sciences employ a causal, rather than a teleological, concept of function. This is in the spirit of Cummins's (1975) systemic analysis of function as the causal contribution a structure makes to the overall operation of the system that includes it. Cummins's concept of function is not a historical or evolutionary concept. According to Cummins, a component of a system may have a function even it was not designed or selected for.. Wakefield has tied disease conceptually to an evolutionary concept of function as a naturally selected capacity. It is doubtful if this connection can be found in either science or common sense about disease. Perhaps in some areas of biology functional ascription is indeed teleological. However, most theorists who have attended to biomedical contexts agree with Boorse and Schaffner that the function of an organ or structure can be understood without thinking of it as an adaptation. Medical understanding requires that functional structures can be identified and analyzed in terms of their contribution to the overall maintenance of the organism as a living system. Explanation in medicine takes a model of the normal realization of a biological process and uses the model to show how abnormalities stem from the failure of normal relations to apply between components of the model. This requires a non-historical function concept, one that is at home in casual-mechanistic, rather than evolutionary, explanation.

Functional attributions in medicine appear to get their sense from the role they play in showing how the overall performance of a biological system depends on the contributions of its component systems, without further tying the systems to an overall goal. Lange (2007) explicitly follows the systemic approach to function. He argues that diseases are incapacities that explain symptoms in causal-analytic terms. An evolutionary approach faces problems in specifying what the overall evolved function of a system might be and showing how functions contribute to it. First, it is very difficult to assess the relevant evidence that a given biological systems is — as in Wakefield's treatment — the product of natural selection (Davies 2001, Chapter 5). Since many ailments do not prevent one from living and having children, it is even harder to show that a disease is necessarily the product of a malfunction that lowers fitness or — as in Boorse — interferes with survival and reproduction. Another problem for Wakefield is that if you regard evolutionary dysfunction as partly constitutive of disease then if an illness depends on structures that have no evolved function, it cannot really be an illness. A biological structure might be a spandrel or a by-product, or have some other non-selective history. Such a structure cannot malfunction in Wakefield's sense, and so it cannot be diseased.

Objections to an evolutionary notion of medical malfunction do not show that there is anything wrong with the general idea of basing judgments of health and disease on a scientifically established picture of the normal functional decomposition of human beings. However, on this account, it becomes harder to retain the conservative project that looks for the natural phenomena that fall under, and are therefore constrained by, our folk concepts of health and disease. Wakefield, for instance, thinks some psychiatric diagnoses flout our intuitions by attributing disorder on the basis of behavior alone without looking for malfunctioning mental mechanisms (1997a). He appeals to intuitions to derive necessary and sufficient conditions for the folk concept of mental disorder, and assumes that science should search for the psychological processes that fit the concept thus defined. But it is one thing to take intuitions as a starting point, and another to say that they are hegemonic. Boorse, too, adduces everyday linguistic usage and commonsense intuitions as evidence, even though he claims to be discussing the clinical concepts of health and disease.

A revisionist can say that a condition we currently disvalue but do not regard as a disease may turn out to involve malfunction and hence to be a disease, whatever our intuitions say. Conversely, we may think something is a disease but we might be wrong, just as we were wrong about drapetomania or masturbation, which do not causally depend on any biological malfunction. Conservatives resist this possibility. Wakefield claims that we have intuitions about human nature that make it “obvious from surface features” whether underlying mechanisms are functional or dysfunctional (Wakefield 1997b, 256). But it is an empirical discovery whether one's physiology or psychology is functioning properly, not something to be decided from the armchair, or even from inspecting surface features.

Once we hand over the task of uncovering malfunction to the sciences we can no longer make common sense the ultimate arbiter, unless we wish to explicitly import, into the concept of disease, considerations derived from folk theories of what normal human nature amounts to.

The normative and scientific components of the analysis are in tension. The analysis of disease as depending on malfunctioning biological components requires a functional decomposition of human biology. If that decomposition is to be independent of what we think people should be like, it should not be regulated by common sense theories of human nature, but discovered by science. We must be able to ascertain, within acceptable limits of variation, the biological standards that nature has imposed on humans. The goal of finding out how a biological system works is fixed by our interests in health and well-being, but the naturalist's assumption is that the goal is met by discovering empirical facts about human biology, not our own, culturally defined, norms. So, we diagnose someone as suffering from mesenteric adenitis not just because they are in discomfort due to fever, abdominal pain and diarrhea, but because the lower right quadrant of the mesenteric lymphatic system displays abnormal inflammation. This thickening of the nodes is not just the objective cause of the discomfort, it is an objective failure of the lymphatic system to make its normal contribution to the overall system. For the naturalist's program to work, the biological roles of human organs must be natural facts just as empirically discoverable as the atomic weights of chemical elements. That may result in the overturning of common sense.

This raises a further issue. It is widely believed that function concepts are intrinsically normative, since they are teleological. Therefore, the objection continues, claims about natural functional and malfunction introduce normative considerations into the foundations of medicine, which are supposed to be purely scientific.

The view that the correct functional decomposition of humans can be discovered in nature is very strong. It's the view that natural functional standards for human nature exist independently of what people think. The idea is that in cases where we can ascribe function to a physiological mechanism the standards of good performance are supplied by nature and not by human values. If that can be done, then malfunction can be understood as a failure of the system to function as it is naturally supposed to. Whether or not this should be seen as normative, it is not the socially relative normativity appealed to by constructivists. The crucial point is that in the life sciences, some biological system can fail to behave as a theory predicts without impugning the prediction: we can say that the system is malfunctioning. This contrasts with other sciences, in which, if a system fails to behave as predicted, the fault lies with the science, not the system.

But where is an account of malfunction to be found? Supporters of an evolutionary account of function advertise the ease with which an account of malfunction follows from the theory as one of its virtues. Their idea is that we can say when a system is malfunctioning by observing that it is not carrying out the job which natural selection designed it to perform. In contrast, it is widely believed that systemic accounts of function cannot deal with malfunction at all. The argument goes like this: what a system is taken to do is relative to our explanatory interests, and that a putative malfunction can just be understood as a contribution to a different property of the system. Davies (2001) argues that the first of these claims can be defeated by restricting functional ascriptions to hierarchically organized systems in which lower level capacities realize upper level ones. That gives us a characterization of function independent of our explanatory interests.

Godfrey-Smith (1993) argues that systemic concepts of function do permit attributions of malfunction. He argues that a token component in a system is malfunctioning when it cannot play the role that lets other tokens of the same type feature in the explanation of the larger system. Davies (2003, 212) denies this. He says that functional types are defined in terms of what they can do and that if a component cannot carry out its normal contribution to the overall system then it ceases to be a member of a type. However, Davies' objection appears to fail, at least in medical contexts, if we can identify components apart from their functional roles. Suppose we can identify biological components in terms of their anatomical position and relationships to other organs. If so, we can say that an organ in the position characteristic of its type remains a member of that type even though it has lost some capacity characteristic of that type, and hence is malfunctioning. Reasoning like this permits doctors to identify organs as normal or abnormal during autopsies, even though every system in a corpse no longer possesses its normal function in Davies's sense.

This leaves unaddressed the issue of how we determine what normal function is. Wachbroit (1994) argues that when we say that an organ is normal, we employ a biomedical concept of normality that is an idealized description of a component of a biological system in an unperturbed state that may never be attained in actual systems. Boorse (1977, 1997) insists that the notion of normality in biomedical concepts is statistical — how things usually are in a reference class, but this view faces the problem of specifying the reference classes in an informative way. But given the amount of variation within a species, it will always be hard to find reference classes which share a design. As Ereshefsky (2009) puts it, Boorse assumes that statistical normality coincides with the kind of normality that medicine cares about, but this looks wrong. Wachbroit (1994, 588) argues convincingly that the role of normality in physiology is like the role that pure states or ideal entities play in physical theories.

Normality and Variation

Statistically, a textbook heart, for example, may be very rare indeed. But it is the account of the organ that gets into the physiology textbook. The textbook tells you what a healthy organ is like by reference to an abstraction—an idealized organ. This concept of normality is not justified by appeal to a conceptual analysis that aims to capture intuitions about what's normal. It draws all its authority from its predictive and explanatory utility: against the background of assuming normal heart function, for example, we account for variation in actual hearts (a particular rhythm, say), by citing the textbook rhythmic pattern (which may be very unusual statistically) and identifying other patterns as arrhythmic. The point of textbook depictions of human physiology is to identify an ideal system that enables us to answer “what if things had been different questions” (Woodward 2003, Murphy 2006). The role of an idealization, in this system, is to let us classify real systems according to their departure from the ideal. So normal human biological nature, in this sense, is an idealization designed to let us impose order on variation.

Variation in biological traits is ubiquitous, and so establishing whether a mechanism is functioning normally is difficult: nonetheless, biologists do it all the time. But not all diagnoses can be tied to a break between normal and abnormal functioning of an underlying mechanism, such as a failure of the kidneys to conserve electrolytes. Nor can we always discover some other abnormality, such as the elevated levels of helicobacter pylori bacteria that have been found to be causally implicated in stomach ulcers (discussed in detail by Thagard 1999). Some conditions, such as hypertension, involve cutting between normal and pathological parts of a continuous variation, even in the absence of clear underlying malfunctions that separate the populations. The Boorsian tradition has tried to deal with the problem of variation by tying assessments of function and malfunction to reference classes, which Boorse (1977) treated as natural classes of organisms that share a uniform blueprint. Kingma (2007, 2010) has recently argued that reference classes cannot be established without normative judgements, contra Boorse, who believed them to be objectively discoverable parts of the natural order. Kingma contends that Boorse's account of function needs to capture not only the qualitative causal contribution made by a system to overall functioning, but also the quantitative features of its contribution: a healthy heart is not just a pump, but a pump that works at a given rate. In addition, a system must be capable of working in a variety of situations, including rare ones that require a physiological response to a crisis. Kingma argues that Boorse's Biostatistical theory cannot capture statistically unusual yet functional situations, and concludes that we need to appeal to situation-specific functions. (Cf. Canguilhem (1991 p.196)who argued that disease is only abnormal relative to a clearly defined context.

Kingma also points out that organs can become diseased even if they do act in a situationally appropriate way. Liver damage due to paracetamol overdose is obviously not healthy, she says, but the liver is not doing anything situationally inappropriate. That is, a reduced level of function in the context of paracetamol overdose is the situationally appropriate way for the liver to perform. Kingma offers Boorse a dilemma. First, he can either abandon the notion of situationally specific functions. This means failing to recognize the dynamic nature of physiology and leading to absurdities such as the claim that a gut which is not currently digesting because it is empty of food is, in fact, diseased. Or, second, Boorse can acknowledge situation-specific functions, in which case he must say that some systems are healthy (because they are acting as they should in that situation) even though our intuitions insist that they are unhealthy, because there are diseases that are statistically the norm in some situations. Hausman (2011) responds that from a Boorsian perspective the crucial question is whether the normal response – the organism doing its job under stress – renders the system incapable. The digestive system may respond appropriately to poison but in doing so it becomes incapable of normal function on average. If a victim of a poisoning were to a eat a large unpoisoned meal, her digestive system would function much less well than that of the average unpoisoned person in similar circumstances.

Following Boorse, Hausman assumes that there is an average range of performance within a normal population in normal circumstances that can tell us what physiological profile a healthy system ought to have. His reply is developed and expanded by Garson and Piccinini (2014). The issue is whether these normal circumstances can be specified without begging the question, or whether Wachbroit is correct to think of medical normality as an idealization that is unrelated to statistical normality. On any approach, a worry is that if we cite behavioral factors in establishing normality they will reflect contested conceptions of human flourishing. Distinguishing failures to flourish from functional abnormalities will always be a special problem for psychiatry. For example, judgments of irrationality are central to many psychiatric diagnoses, and our standards of rational thought reflect not biological findings but standards derived from normative reflection. The possibility of psychiatric explanation employing the methods and models of physical medicine, then, depends on how much of our psychology is like the visual system—i.e. decomposable into structures to which we can ascribe a natural function (Murphy 2006). Within medicine more generally, the prospects for a general naturalism about disease depend on our ability to understand human biology as a set of structures whose functions we can discover empirically, and our capacity to understand disease causally as the product of failures of those structures to perform their natural functions.

Health

Health and Biology

As noted above, conceptions of health, like conceptions of disease, tend to go beyond the simple condition that one is biologically in some state. In the case of health, one view is that a healthy individual is just someone whose biology works as our theories say it should. This is the counterpart, in theories of health, to simple objectivism about disease. As with disease, however, most scholars who write about health and add further conditions having to do with quality of life. On this view, we need a threefold distinction between disease, normality and health, where health involves some properties of a person's life that enable us to evaluate how well it is going for them. Carel (2007, 2008), for example, thinks that the important thing about health is one's lived experience of one's own body, and in particular, that one should not feel estranged or alienated from one's body. Carel argues that health should be understood phenomenologically as the experience of being at home in one's lived body, rather than merely the normal functioning of the body seen as a biological unit.

From the naturalist perspective, one problem with this proposal is that it ignores the fact that one can feel perfectly at ease with one's lived body even if one harbors, unaware, a diseased system. Indeed, Carel argues that someone who is ill can be, in her sense, healthy, if they are adapted to their bodily predicament; from her perspective, objections like the one just mentioned miss the point, since they privilege a biological perspective rather than a phenomenological one. Her project is avowedly revisionist: she wishes to replace existing concepts of health with views that aim to capture the experience of being healthy (or unwell).

Carel's stress on experience is directly challenged by views like Gadamer's. He insists (1996, 113) that it is absurd to ask someone if they feel healthy, since health is “not a condition that one introspectively feels in oneself. Rather, it is a condition of being involved, of being in the world, of being together with one's fellow human beings, of active and rewarding engagement in one's everyday tasks”. Gadamer's healthy person is someone who is in harmony with their social and natural environment, and disease is a disturbance of this harmony. Canguilhem (1991, 2012) thinks of health as flexibility, in the sense that a healthy organism can tolerate environmental impacts, adapts to new situations and possesses a store of energy and audacity. This is not something that can be measured by physiology (2012, p.49). Canguilhem's approach suggests what is wrong with Gadamer's objection to phenomenological accounts of health. There does not have to be a special feeling that is the feeling of being healthy. Rather, for a view like Canguilhem or Carel's, healthy people experience the world as an arena to express themselves in rather than a bunch of threats. It may well be that perspectives like Carel's are neglected in contemporary medicine, and that they are especially important in disability studies. However, it does not follow that the concepts of health and disease, rather than aspects of our practices that employ those concepts, should be reformed along the lines she suggests. In general, though, accounts of health, compared to those of disease, are less concerned with trying to capture a scientific or clinical concept.

Embedded Instrumentalism

Gadamer's view is reminiscent of what Richman (2003) calls “embedded instrumentalist” theories, which claim that health is indexed to goals: how healthy you are depends on how well you can fulfill your goals. Such theories are very popular. Nordenfelt (1995) considered two versions of this approach. One version defines the goals relevant to health as needs, which are understood as having a biological basis. Another view defines goals in terms of the ambitions and desires of the individual. Nordenfelt (1995, 90) argues that a healthy person is one who can satisfy her “vital goals”, which are those that are necessary and sufficient for her to be minimally happy.

Embedded instrumentalist theories of health have an obvious appeal. Once we argue that health involves judgments about how well a person's life is going, we need a way to evaluate that, and an immediately attractive idea is that someone's life goes well if they can achieve their ambitions or satisfy their goals. An apparent difficulty, however, is that much the same terrain is covered by theories of well-being, and while people think that being healthy is important to their well-being (Eid and Larsen 2007), they do not identify the two. Rather, they think of health as a component of well-being.

Some embedded instrumentalist theories, though, appear to be in danger of defining health in such a way that it is synonymous with well-being. Richman (2003), for example, develops his view, (the “Richman-Budson view”) to deal with objections that Nordenfelt raises against goal-based views, such as the worry that someone with very low ambitions will count as healthy just because she is easily satisfied. Richman (2003, 56–57) supposes that someone is healthy if she can strive for a consistent set of goals that would be chosen by an idealized version of herself if she were fully aware of her “objectified subjective interest” (p.45). That is, they are the goals she would choose if she had complete knowledge of herself and her environment and perfect rationality.

In this case it seems that a theory of health is in danger of becoming a general theory of well-being, and Richman does not discuss the relationship between the two. A further complication is the relationship between medical interventions designed to cure diseases, and other medical interventions which are “enhancement technologies” (Elliott 2003). The line between enhancement and therapy is very hard to draw: Harris (2007, 21) for example, uses the example of vaccination, which is both a therapeutic protection against infection and an enhancement of our natural immune system. Perhaps, too, many of us would benefit from a boost to our powers of concentration, or a lift in our mood, which pharmaceuticals might supply. But neurological enhancements, unlike vaccines, can help us to meet our goals without guarding against disease. Perhaps what is needed is a weaker view of the relation between health and goal-directedness, such as that offered by Whitbeck (1981, 620). Whitbeck defines health in terms of the psychophysiological capacities of an individual that support her “goals, projects and aspirations in a wide variety of situations”. This view loosens the tight Richman-Budson connection between health and goal-directed action, and suggests a view on which we can see biological capacities as at the core of health in so far as they help people's lives to go better.

Schroeder (2013) has taken issue with this whole approach. He argues that “health” is a fundamentally comparative term like tall. Two human beings can both be tall even if one is taller than the other, whereas it makes no sense to think of two straight lines, one of which is straighter than the other. Schroeder argues that if we see health as fundamentally comparative in this way we can recast several conceptual, ethical and policy debates. For example, instead of thinking in terms of non health-related differences among the healthy we could think in terms of gradations of health. Schroeder also thinks that his approach makes intergenerational or cross-temporal comparisons more easy, since we could say that a medieval serf was healthy in their time, but nonetheless less healthy than a modern person who is, by our standards, chronically ill. An approach like this might offer some traction on the reference class problem outlined above.

Conclusions

Naturalism and constructivism have been distinguished for analytic purposes in this essay but they are not always easy to tell apart in practice. The difficulty comes from the fact that there is widespread agreement that our thinking about disease pays attention to both human values and biological phenomena, and it is not always easy to tell how a theorist explains the interactions of these factors, nor whether a given analysis is descriptive or prescriptive. For naturalists the relevant biological processes are departures from good human functioning, to be determined by the relevant science. These biological problems result in what we judge to be difficulties in living. For a constructivist, it is the problems people face in their lives that take priority. Their biological underpinnings are ones we count as abnormal because we have judged them to be both relevant to the conditions we disvalue and also the subject matter of a specific, medical, class of interventions, therapies and other practices. The obstacle to a successful development of naturalism is the problem of establishing a satisfactory, science-based, distinction between normal and abnormal human functioning. Overcoming this difficulty will require a closer engagement by theorists of disease with the relevant debates in the philosophy of biology.

For constructivists, the big problem is to say why we judge some human phenomena to be symptoms of disease whereas others are taken as evidence that someone is criminal or ugly or possessed by demons or something else we do not admire. It is not generally true that we think that if someone's life goes badly it is because he or she is unhealthy, so constructivists owe us an account of what makes a certain class of judgments distinctively medicalized. Many theorists have traced the changes in medicalization over time, but a satisfactory constructivist concept of disease requires an analysis of how medical thinking comes to play a role in human societies to begin with.

Ronald W. Pies, What Is “Disease”? Implications of Chronic Fatigue Syndrome, Psychiatric Times (March 2, 2015)

What do physicians intend by the term “disease”? This may strike many clinicians as a philosophical question more suited to medieval scholastics than to practicing physicians. But the recent 235-page report on “systemic exertion intolerance disease” (SEID) from the Institute of Medicine1 (IOM) casts this question in a new light and has many practical implications for patients, physicians, and third-party payers.

The definition of “disease” has been a matter of contention since the dawn of clinical medicine. For example, the ancient Greek academies of Knidos and Kos had differing views of disease.2 Knidos, the school of Aesculapius, recognized the discrete morbid entity—such as an abscess or tumor—as the defining feature of disease, subservient to the general rules of pathology. The more empirical school of Kos, associated with Hippocrates, emphasized the sick individual with his particular kind of misery. In effect, these two schools saw disease either as a specific pathological process or as a particular human experience whose character was determined by the patient’s manner of presentation.

In the 19th century, medical science was revolutionized by the German pathologist Rudolf Virchow and his famous pronouncement: Es gibt keine Allgemein krankheiten, es gibt nur Local krankheiten—“There is no general, only local, disease.” But Ludwig Aschoff, Virchow’s colleague, argued that Virchow wished merely to localize lesions, not diseases.3 There are indeed reasons to believe that Virchow conceptualized disease as a generalized condition of the living organism, which, unlike lesions, disappears when the organism dies.

To this day, the definition of disease remains controversial. Recently, in its deliberations on obesity, the AMA requested an advisory opinion from its Council on Science and Public Health. The question before the Council was, “Is obesity a disease?” The Council’s considered response was a lesson in both the limits of language and the merits of humility: “Without a single, clear, authoritative, and widely accepted definition of disease, it is difficult to determine conclusively whether or not obesity is a medical disease state.”4

IOM's clinical criteria for SEID diagnosis:

Substantial reduction or impairment in the ability to engage in pre-illness levels of occupational, educational, social, or personal activities

Postexertional malaise

Unrefreshing sleep

Either cognitive impairment or orthostatic intolerance (or both)

Note that the SEID criteria do not require the identification of any specific biological, biochemical, or neuroanatomical abnormality. Rather, they entail a substantial degree of distress and impairment.

Unfortunately, in the past 50 years, narrow interpretations of Virchow, such as those of the late psychiatrist Thomas Szasz, have dominated discussions of what constitutes “disease.”5 This has led to the claim—mistaken, in my view—that only those conditions with specific and identifiable pathophysiology or anatomical abnormalities “count” as disease.

Yet these criteria fly in the face of medical diagnosis throughout the ages and are not consistent with several modern-day diagnoses in the fields of neurology, psychiatry, and pain medicine. Physicians in these fields recognize that many states of severe suffering and incapacity cannot yet be causally linked with specific biochemical or anatomical findings.5 For example, migraine headache, trigeminal neuralgia, and even epilepsy remain clinical diagnoses—made primarily on the basis of the patient’s history and subjective reports. (Physical examination and imaging studies, of course, are important in ruling out certain lesions, such as a brain tumor.)

This is also true for the vast majority of psychiatric disorders. It is the patient’s degree of suffering and incapacity—or distress and dysfunction—that defines a state of disease (etymologically, di-sease). Of course, pathophysiologic correlates, imaging studies, and biomarkers can help us understand the underlying biological nature of the specific disease process and devise appropriate treatments. However, such abnormalities are neither necessary nor sufficient for the recognition of “disease” as a profound and troubling human experience.5

Indeed, in the edition of Harrison’s Principles of Internal Medicine that I used when I was a resident, the following breathtakingly broad definition of disease was put forth:

The clinical method has as its object the collection of accurate data concerning all the diseases to which human beings are subject; namely, all conditions that limit life in its powers, enjoyment, and duration [italics added].6

The editors went on to say that the physician’s “. . . primary and traditional objectives are utilitarian—the prevention and cure of disease and the relief of suffering, whether of body or of mind . . . [italics added]”6

Now comes the IOM report, which has renamed so-called chronic fatigue syndrome (also called “myalgic encephalomyelitis”) as “systemic exertion intolerance disease” (SEID) and proposed essentially clinical criteria for its diagnosis. (Our word “clinical” is derived from the Greek klinikē “bedside”—so, diagnosis made at the bedside). In brief, the SEID criteria entail the following:

Substantial reduction or impairment in the ability to engage in pre-illness levels of occupational, educational, social, or personal activities

Postexertional malaise

Unrefreshing sleep

Either cognitive impairment or orthostatic intolerance (or both)

Note that the SEID criteria do not require the identification of any specific biological, biochemical, or neuroanatomical abnormality. Rather, they entail a substantial degree of distress and impairment. To be clear: the report did find evidence of a strong association of SEID with diminished natural killer cell function; Epstein-Barr virus infection; decreased cardiopulmonary function; and neuropsychiatric testing abnormalities—but these correlates are not required for diagnosis of SEID.1 Similar biomarkers and associated abnormalities have been found in several psychiatric disorders. For example, abnormal eye movements can distinguish persons with schizophrenia from normal persons with considerable accuracy.7 Nevertheless, current diagnostic criteria for schizophrenia remain clinical, as with SEID.

Already, the IOM report has attracted sharp criticism, with some physicians questioning the lack of specificity in the SEID criteria and worrying about the potential for overdiagnosis and even outright fraud. These risks are not trivial, but I would argue that as physicians, our first duty is the recognition and relief of human suffering and incapacity, whether we can identify the specific pathophysiology underlying the patient’s condition. With respect to SEID, the IOM report makes it abundantly clear that this condition can have profoundly adverse effects on the sufferer’s social and vocational function.1

To be sure, we must continue to investigate the biological underpinnings of SEID, just as we must in disease states such as schizophrenia and atypical facial pain. When our patients are suffering and incapacitated owing to some internal process, however, we have both clinical and ethical reasons to recognize that disease is present, and to do our utmost to treat it.

Abstract:

This paper presents a framework for understanding the relationship between rational choice and emotional behavior. Emotions are interpreted as temporary albeit predictable changes in preferences, abilities, and beliefs. People act rationally in anticipation of their own emotional reactions to provocations and other stimuli; they also act rationally when under the influence of emotion. The law needs to take account of both of these effects. The paper discusses (1) the sanction for murders committed under the influence of rage or hate, (2) the treatment of prejudicial evidence such as gory photographs, (3) safety regulation when individuals are subject to fear or dread, (4) contract and judicial remedies when parties become angry at each other, and (5) cost-benefit analysis of projects that provoke emotional responses.

Roy Richard Grinker, Reframing the Science and Anthropology of Autism, 39 Cult. Med.  Psychiatry 345 (2015)

The papers in this collection represent an important step forward in the ethnographic study of autism. Their focus on sociality and social context is especially important today as so much of the attention paid to autism in the scholarly literature and in the media concerns advances in neuroscience, cellular and molecular biology, and does not examine the non-medical aspects of autism. The field of genetics, to cite just one example, offers an enormous range of possibilities for using genetic variations to identify the alleles and mutations that influence neurological development. But as the papers in this collection suggest, we can take the medicalized, genetic approach to autism too far, to a point at which a disease construct is so profoundly fetishized that we fail to question the validity of the construct, and to see its cultural constitution. Medicalized approaches to autism, at least as autism is now conceptualized as an expansive spectrum, also risk making a disease out of traits that are likely distributed in varying degrees among the general population, obscuring the positive characteristics of autism that contribute to human diversity and creativity, neglecting the possibility for new forms of sociality to emerge, and diminishing the role that autism can play in forming new social identities.

The value of an anthropologically informed approach to autism, in my view, has less to do with relativism—in which we recognize autism as just another form of being, and then appreciate that form for its differences from an assumed norm— than with its ability to unmask the cultural foundations of scientific representations, and to comprehend both the social life of autism, as a construct, and autistic sociality. The experiences of an autistic person—whether his strengths and abilities are supported or neglected, whether he is idealized or demeaned and bullied, whether he is integrated into community life or excluded—are not written in his cells. As Olga Solomon suggests in her arguably post-humanist study in this volume, animal companionship shows that sociality is less an individual trait and more ‘‘a capacity realized through certain kinds of social interactions.’’ Yet much scientific research often depersonalizes—or perhaps de-socializes—forms of human difference by explaining them in terms of biological mechanisms.

When Francis Collins was Director of the National Human Genome Research Institute, he articulated his vision for the future:

The time is right for a focused effort to understand, and potentially to reclassify, all human illnesses on the basis of detailed molecular characterization. Systematic analyses of somatic mutations, epigenetic modifications, gene expression, protein expression, and protein modification should allow the definition of a new molecular taxonomy of illness, which would replace our present, largely empirical, classification schemes, and advance both disease prevention and treatment (Collins et al. 2003: 841).

This view expresses a problematic expectation that a genetic foundation would establish disorders as ‘‘real’’ and thus lead to a more valid genetic nosology in all areas of medicine, including psychiatry. It is problematic because while the relationship between a biomarker and a constellation of behaviors might be empirically verifiable, those behaviors only become a ‘‘disorder’’ when society constructs them as such, and a ‘‘disability’’ only when the social environment cannot accommodate them.

Biological descriptions of human differences certainly cannot help us understand the role social context plays in the identification and treatment of autism. Indeed, all of the articles in this collection stress the need to study what people experience, and how they understand their experience. As Sarrett shows in this volume, the explanatory models people develop for autism are engines for social action. They affect how people think and behave in every domain of life—from religion, kinship and marriage, to medical care, social participation, labor, education, esthetics, and play. Explanatory models can be deeply rooted in society, as when autism is conceived in terms of longstanding religious beliefs about supernatural causation. Even moribund models, like the psychoanalytic belief that autism is caused by cold, unloving mothers, can have a long legacy. One wonders how the kind of parent– child training in India described by Brezis et al. in this volume might be received in the United States where, due to the refrigerator mother hypothesis, any sort of intervention aimed at parents suggests that the providers blame the parent for the child’s autism.

Now imagine if there had been a biomarker in the early twentieth century for the group of symptoms we today call autism. In the United States at least, the condition might have been called autism. But it is likely that, apart from possessing the knowledge of, say, a DNA sequence implicated in autism, little would have been different. Parents might still have been blamed for their children’s problems. People with autism would still have been institutionalized. They would have had few educational or job opportunities, and they and their families would still have been stigmatized, because the core features of autism would still have existed in the historical context of early twentieth century psychiatry.

It is important to remember that the diagnosis of diseases made on the basis of an identified bacterium, virus, or cancer, are also grounded in society and history. Yet, biomedical approaches to diseases (and disabilities) often assume that disease constructs are stable, uniform, or grounded in nature rather than culturally and historically contingent (Wilce 2009; Hahn and Kleinman 1983). The rich metaphors societies employ to give meaning to AIDS (plague, punishment, military invasion), cancer (evil, insatiable invader, death sentence), or leprosy (corruption, decay), for example, show that even conditions one might think are based on empirically verifiable phenomena are always constituted by normative values. By reducing disease, and even identity, to biological materials and mechanisms, genetics poses a challenge to the view represented in this volume—that societies construct their own worlds—a view we should not forget is fundamental to anti-racist and other antidiscriminatory ideologies. Difference constructed on the molecular level is still difference, with all the same (and perhaps even more powerful) possibilities a purely social classification presents for shaping and entrenching inequality.

Scientific representations tend to view neuropsychiatric conditions, in general, in terms of pathology, yet even these representations do not always derive only from scientific research and writing. Robert Barrett (1998) has clearly articulated how the conceptualization of schizophrenia as the split mind (literally, skhizein, ‘‘to split,’’ and phre¯n, ‘‘mind’’) emerged out of at least two intellectual traditions in Europe. The arts and literature that emerged out of nineteenth century Europe (Faust, Dr. Jekyll and Mr. Hyde, Doppelga¨nger, Frankenstein, and The Picture of Dorian Gray, for example) proposed the existence of a binary mind, defined in large part by the oppositions dark and light, good, and evil. Similarly, in French evolutionary thought, scientists hypothesized that physical and cultural variation in the world was the result of the degeneration of the mind, or the disintegration of the mind into its parts. Europeans were models of the perfect and coherent mind, while non-Western peoples, and people with severe mental illnesses, represented the fragmentation, disintegration, and degeneration of the mind. Remarkably, more than 140 years after Dostoevsky wrote about the ‘‘second self’’ in The Raw Youth (1875), as the sign of the disintegration of the mind, even a cursory examination of advertisements for twenty-first century anti-psychotic pharmaceuticals will yield representations of psychosis as a divided mind, representations that owe their existence largely to European Romanticism, and certainly not to any scientific discoveries.

In both psychiatry and in parents’ memoirs, autism has been conceived in cultural terms as the loss of a person or the loss of soul. Consider New York University’s Child Study Center 2007–2008 outreach campaign for mental illness awareness and treatment, called ‘‘Ransom Notes’’ (Kras 2010). The advertisements, posted on bus stop shelters and in other print media, were letters from kidnappers. One letter to a parent, and signed ‘‘Autism,’’ read, ‘‘We have your son. We will make sure he will not be able to care for himself or interact socially as long as he lives. This is only the beginning.’’ This view of the autistic person as lost, abducted, kidnapped, is not the result of scientific research, but of a particular objectification of the human mind, and the idea that the person with autism has been damaged. The autistic person, from this perspective, is deficient and dysfunctional. In many memoirs of autism written by parents, diagnosis becomes both a proxy for the onset of autism and the sudden disappearance of the child. Witness the opening words to the preface of the book Strange Son, written by Portia Iversen, the founder of Cure Autism Now, and previous member of the National Advisory Mental Health Council at NIMH (2006: 1) ‘‘It was his mind they came for. They came to steal his mind….I knew it was in our house…They were very, very dark things. Night after night, I sat beside his crib. I knew he was slipping away from us, away from our world. And there was nothing I could do to stop it from happening… And then one day, it happened. He was gone.’’ The first chapter is entitled ‘‘Departure of the Mind.’’ In her book, The Accidental Teacher, Annie Lehman (2009: xvi) calls autism ‘‘a greedy disability,’’ because it takes so much away from so many areas of functioning. In the U.S., the idiom of injury has become commonplace among some anti-vaccine advocates, who narrate their child’s experiences in terms of wrong-doing, and prefer to see their child not as autistic but as ‘‘vaccine-damaged’’ or ‘‘mercury poisoned.’’

Narratives about autism, perhaps like all ‘‘disorders,’’ are social and linguistic products. Of childhood developmental disorders in general, Danforth and Navarro note that narratives are ‘‘co-fabricated within the complex construction and contestation of cultural codes, norms, and identities’’ (Danforth and Navarro 2001: 167). Narratives are also co-fabricated through the interaction of distinct discourses. Sometimes these narratives are in antagonistic relation. This is the true in the case of Brazil, as described by Rios and Andrada in this volume. At other times, there is a merging of ideas, as when the participants in a conversation must to some extent adopt the linguistic and conceptual framework of their interlocuters. As Cascio’s analysis of the concept of rigidity in Italy illustrates, different discourses with very different intentions not only interact with each other, but can also begin to overlap.

The critique of biomedical representations, however, should not blind us to the problem of the culture concept. As the editor of this collection, Ariel Cascio, warns in her introduction, some culturalist formulations pose risks as well. Scholars who accept the idea that autism constitutes simply another way of being—a way of being that the medical establishment has pathologized—risk accepting at face value their interlocuters’ ideologies and categories (for example, ‘‘neurodiverse’’ and ‘‘neurotypical’’) or, worse, fetishizing or ‘‘othering’’ autistic individuals. There is also a risk of both simplifying and idealizing autism. Those who embrace the view that autistic people have a distinct culture tend to represent autism through selfadvocates, people who are often far more verbal, socially capable, independent, and empowered than others: autistic people who are non-verbal, self-injurious, have seizure and other comorbid disorders, and may require lifelong institutional care. It is clear that even the concept of an autism spectrum cannot easily account for the wide range of suffering that exists. Nor can suffering be accounted for in a relativist frame only as the product of a society’s norms, or intolerance of neurodiversity. Even those who challenge institutional norms and the ‘‘deficit’’ model of autism typically embrace the word itself and adopt their own view of what is ‘‘normal.’’ Scientists, it could be argued, frequently mistake social distinctions for biological ones; neurodiversity advocates, it could be argued, do the opposite.

In addition, sometimes what appears to be a product of ‘‘culture,’’ may be the result of something external to an individual or family’s everyday experience, and may not reflect values that are deeply rooted in their communities. So for example, while Brezis et al. note significant differences in the topics of concern voiced by poorer and wealthier families prior to the parent–child training intervention in India, those differences disappeared after the training. Similarly, disparities in diagnosis of autism among African-American children could be the result of cultural differences among African-Africans, but may just as likely be the result of forms of institutionalized racism, in which services are unequally distributed in a population. Lower rates of diagnosis of autism among Latinos in the U.S. could be the result of their attitudes toward child development and child care, but could also be due to the fact that there are fewer autism programs in regions, states, counties, or neighborhoods where these populations live. Or it could be because legislation in some locations where they live makes it more difficult for children who live there to become eligible for services.

The concept of culture in autism research is thus useful not just for characterizing a community’s system of meanings that influence how autism is identified, managed, experienced, etc., but for showing that those meanings are constructed and can therefore be changed. In an earlier volume on autism, published in Ethos, Nancy Bagatell (2010) describes the recent emergence of autistic communities and autistic identities as both a rejection of biomedical and deficit model, and as a new form of sociality made possible by historical conditions. In Silicon Valley, for example, autism is increasingly less stigmatized and more valued as employers begin to associate autism with the cognitive skills necessary for innovation in high technology. Bagatell (2010: 51) writes, ‘‘It is evident that as society is transformed by technology, the nature of human sociality may be scaffolded and transformed in ways that come to mirror an autistic sociality and thus reframe the disabling properties of autism itself in more positive terms.’’ Fein’s contribution in this volume similarly posits a reciprocal relationship between autism and culture. The teenage campers with whom she conducted fieldwork, most of them previously diagnosed with Asperger’s Disorder, engaged with their counselors in highly structured live-action roleplaying games (consisting of fairies, dragons, and other mythological characters) that were, in Fein’s words, ‘‘congruent with what participants needed from their cultural ecology in order to organize themselves and their interactions.’’ She reports that among the children there was a sense of belonging rather than stigma, a sense of an emerging subculture, or in the words of one teenager, ‘‘my tribe.’’ Cultural practices thus can shape the experience of autism, and autism can in turn shape cultural practices. Fein calls the camp a folk healing system and a ‘‘generative sociocultural space.’’ More than that, the camp, and all of the other ethnographic contexts described in this collection, provides opportunities for people on the autism spectrum to construct and participate in society, thus mitigating the exclusions that create stigma. All of these authors focus on what people with autism can do, rather than what they cannot do, or what might have been; and they equally focus on what societies can do to change the lives of people with autism.

Writing about a different aspect of human thought and behavior, the philosopher Paul Ricoeur (2004: 21) once warned of the tendency to think about memory as flawed, imprecise, and deficient. Memory is devalued because it is a divergence from a kind of perfection—that is, perfect knowledge of the past. For Ricoeur, memory is, paradoxically, a way of moving forward in time, and should be celebrated as a remarkable capacity. But this view is possible only if we shatter the historian’s illusion that there is a real, objective, unfiltered, unconstructed truth to be found, and the illusion that historical memory is, like the nineteenth century concept of schizophrenia, a degeneration from a point of origin. There is a lesson for autism researchers in this critique of history. The constellation of behaviors and cognitive characteristics that we call ‘‘autism’’ today existed long before we made it an object of knowledge and narrative—before we interpreted it, named it, and started the ongoing process of reinterpretation and redefinition. Our capacity for culture means we have the power to change the history of autism, as we move forward and make a new past, with new narratives.

Abstract:

Many people believe that the “mad genius” notion, which has been a favorite cultural fixture for centuries, is based on established scientific fact. Much of the evidence for the connection between great creativity and great pathology, particularly affective disorder, comes from the writings of psychiatrists Nancy Andreasen and Arnold K. Ludwig and psychologist Kay Redfield Jamison. For two decades, their studies and books have been widely referenced in both the popular and professional press without critique or comment and often without much detail, suggesting that few people have spent much time with the originals. This article examines their most influential works, encouraging readers to evaluate this evidence for themselves, because the author believes that many of their claims have had unfortunate implications for the perception of creativity and the credibility of psychological research in general. The author considers the inherent difficulties of generating any scientific findings in this area, and concludes by discussing the signs of a hopeful trend to celebrate, rather than pathologize, people with exceptional gifts.

Summary:

The American Psychiatric Association has now promulgated a revision of its diagnostic and statistical manual (DSM-5). The states of affairs classified are those occasions on which some person is judged by himself and/or others to be ‘mentally disordered’ or ‘mad.’ For those engaged in classifying these disorders, the initial problem involves specification of a principle of discernment in terms of which candidates for classes and for classification are identified. Subsequently, rules based on similarities and differences, are developed for assigning particular cases to a class of disorders, e.g., “Mr. Jones has schizophrenia.” This response to the revision concerns the initial problem - the principle of discernment in terms of which candidates for classes and for classification are identified.

DSM-5 says only the following regarding the judgment that a person is “mentally disordered:”

“A mental disorder is a syndrome characterized by clinically significant disturbance in the individual’s cognition, emotion regulation, or behavior that reflects a dysfunction the psychological, biological, or developmental processes underlying mental function. Mental disorders are usually associated with significant distress or disability in social, occupational, or other important activities.” (American Psychiatric Association, 2013, p. 20)

Is it possible to offer a more conceptually elaborate and useful account of the judgment that a person is mentally disordered? I believe so.

One school of thought depicts persons judged to be mentally disordered as suffering from diseases of the brain. States of madness should therefore be discerned and classified in keeping with knowledge of how the brain, as an element of the nervous system, functions in health and ill-health, and in keeping with the utility of this principle for the practice of medicine in treating and preventing such states. By implication, the practical aim of psychiatry, is to restore and/or maintain the normal functioning of the brain. In terms of medical specialization, psychiatry is, therefore, awaiting the discovery that it is, properly, neurology.

This approach may be adequate for classifying a subset of conditions prominently manifested in behavior and experience such as disorders due to a general medical condition, diseases of the brain, toxins and drugs, and certain developmental and cognitive disorders.

But this principle for identifying all states of madness is inadequate for several reasons. It fails to accurately portray the full range of conditions exhibited and experienced by persons who are judged to be mad. It assigns too much of clinical psychiatry as a specialty of medicine to neurology’s waiting room. And it fails to generate useful conceptual and practical guidance for the care of persons who seek aid from psychiatrists.

In this paper I offer a rationale for an alternative starting point for characterizing persons judged to be mentally ill and in need of psychiatric services. This principle is less sharply focused and less vivid than “mental disease is brain disease,” but I believe, more comprehensive with respect to the range of untoward conditions designated as ‘mental disorders’; it grounds psychiatry as a medical specialty; and, is more useful, overall, in according intelligibility to the practice of clinical psychiatry.

I argue that the conditions to which the psychiatrist attends are best portrayed as diminutions of ‘sanity’ – that form of human health a person enjoys when the elements of his personality are well enough founded, organized, developed, and integrated with one another, and with his knowledge and capacity to choose, so that a person is able, by means of his actions, to secure his prudential interests. Following an exposition of the basic tenets of neurology, I analyze the features of the practical lay judgment that someone is mad, and show that the psychiatric examination, and in particular, the use of the mental status examination presupposes tacit criteria for sanity - the principle of discernment used for identifying problems of health as mental disorders. In addition, this analysis of intended to specify and relate ideas essential to the conceptual origins of psychiatry as a medical specialty. *
