Mental disorder is an urgent and growing public health problem.1 Scientific investigation of this problem has the pragmatic goals of identifying the causes of mental disorders and developing strategies to effectively treat them. Philosophers of psychiatry have participated in the inquiry into the empirical examination of mental disorders, predominantly by debating whether psychopathology is a legitimate target of scientific inquiry and, if so, how mental disorders should be explained, predicted, and intervened on. However, as I show in this paper, (...) these philosophical discussions have mostly neglected the actual state of inquiry in psychiatry and relevant disciplines, as well as the first-person experiences...

I propound a mechanistic theory of natural kinds in the human sciences. By examining a culture- bound psychiatric disorder, bulimia nervosa, I illustrate how partially socially constructed phenomena raise a serious challenge to traditional theories of natural kinds. As a solution to the challenge, I show how the mechanistic approach allows us to include real but partly socially sustained phenomena among natural kinds. This is desirable because the theory of natural kinds supplies (...) the human sciences with a clear normative account of concept formation. Furthermore, my theory suggests a conceptual framework for interdisciplinary research on complex phenomena. As a prerequisite for the mechanistic approach, the concept of natural kind in the philosophy of science must be distinguished from the use of the notion in other parts of philosophy. (shrink)

This paper addresses philosophical issues concerning whether mental disorders are natural kinds and how the DSM should classify mental disorders. I argue that some mental disorders (e.g., schizophrenia, depression) are natural kinds in the sense that they are natural classes constituted by a set of stable biological mechanisms. I subsequently argue that a theoretical and causal approach to classification would provide a superior method for classifying natural kinds than the purely descriptive approach adopted (...) by the DSM since DSM-III. My argument suggests that the DSM should classify natural kinds in order to provide predictively useful (i.e., projectable) diagnostic categories and that a causal approach to classification would provide a more promising method for formulating valid diagnostic categories.

In lieu of an abstract, here is a brief excerpt of the content:The Nature of Proof in PsychiatryPaul Lieberman (bio)Keywordspsychotherapy process, knowledge and psychiatry, externalism, WittgensteinThis vivid clinical report illustrates recognizably, and provocatively, a number of routine, but often unexamined, clinical questions. In its few paragraphs, it depicts challenges that each practitioner confronts, and, in the flux of clinical work, addresses, however implicitly and imperfectly, every day: From what data, and by what processes, does a clinical formulation, or way (...) of understanding, come into being? How do we appraise its accuracy and adequacy? Of what value is even a well-substantiated understanding, in the mind of the therapist, to the patient? What is the power of empathy as a treatment tool? How do we assess someone's status as a “good candidate for therapy?” When, typically, only the outlines of a problem are visible, and its origins and implications are largely hidden, by what right do we recommend psychotherapy, and with what conception, at what level of detail, of what its outcome will be? These are among the questions that Dr. Bailey's story challenges us to address.They are clinical questions, of course, because they deal with empirical matters of fact—psychological processes, outcomes studies, and evidence. But they are also philosophical because, as Freud insisted and Dr. Bailey shows, information obtained in the clinical situation often has power and authority that lead us to believe we understand what is going on, understand the other person, even in the absence of scientifically tested hypotheses, or the clear application of research-based evidence. Interactions between people—including clinical interactions—have a life and ability to engage us. Their meanings can seem so transparent and convincing that no doubt or questioning may seem cogent. At their most powerful, such experiences can reawaken us to important realms of experience and feeling which we might, otherwise, forget, ignore, suppress, deny, or in other ways keep out of awareness; they have the potential to arouse us and reconnect us with truths that, once revived, can seem both valid and important—perhaps the kind of experience that we may derive from works of art or literature (in fact, Dr. Bailey's account could be seen as a clinical parable—meant to be neither true nor false, but instructive). But even less dramatic examples are commonplace: we do routinely claim to know and be able to interpret and understand the actions of other people from our everyday interactions with and observations of them.What is less clear is how to account for these convictions and how to appraise their value, because they do not derive from established scientific procedures. Clinical intuition has a role throughout medicine, but we usually expect it to be subjected later to more rigorous tests to establish the correct diagnosis. Yet, as Dr. Bailey's case illustrates, clinical intuition in the psychiatric encounter seems somehow different. When Colin [End Page 225] leads Dr. Bailey to the conclusion that a “painful lack of wounds” has made him depressed, we find this credible. It seems similarly credible that Dr. Bailey might be anxious about his own capacity to defend his young family, because he says he is, that he perceives Colin as testing his manhood or sincerity, because that seems to fit Colin's temperament, that being accurately understood is helpful, because most of us have had that experience and valued it, and that, most generally, an absence of challenge or of activity could be depressing. But suppose a patient believed that a painful lack of wounds produced diabetes instead of depression, or suppose he had developed epilepsy and attributed that to an absence of combat experience. We might see these as ‘pre-scientific’ or ‘hypothesis-generating’ (or worse). By contrast, it seems timid to consider psychiatric formulations to be always and only provisional or hypothetical.In what ways and to what extent should we expect psychiatry to be different, and why? Several considerations suggest that psychiatry's reasons are not, always and everywhere, the same as those of general medicine, nor are its objectives.In general medicine, we distinguish between signs and symptoms, on the one hand, and “underlying” disease processes, on the other. But in psychiatry, this distinction can be... (shrink)

This paper asks when a natural disease kind is truly 'reactive' and when it is merely associated with a corresponding social kind. I begin with a permissive account of real kinds and their structure, distinguishing natural kinds, indifferent kinds and reactive kinds as varieties of real kind characterised by super-explanatory properties. I then situate disease kinds within this framework, arguing that many disease kinds prima facie are both natural and reactive. I (...) proceed to distinguish ‘simple dependence’, ‘secondary dependence’ and ‘essential dependence’ between a natural kind and its classification, and argue that a natural kind is only really reactive, in an important sense, under conditions of essential dependence. On this basis, I offer a principled hypothesis for why psychiatric kinds tend to be more metaphysically unstable than paradigm somatic disease kinds. (shrink)

In this article, I argue that depression and suicide are natural kinds insofar as they are classes of abnormal behavior underwritten by sets of stable biological mechanisms. In particular, depression and suicide are neurobiological kinds characterized by disturbances in serotonin functioning that affect various brain areas (i.e., the amygdala, anterior cingulate, prefrontal cortex, and hippocampus). The significance of this argument is that the natural (biological) basis of depression and suicide allows for reliable projectable inferences (i.e., predictions) (...) to be made about individual members of a kind. In the context of assisted suicide, inferences about the decision-making capacity of depressed individuals seeking physician-assisted suicide are of special interest. I examine evidence that depression can hamper the decision-making capacity of individuals seeking assisted suicide and discuss some implications. (shrink)

In this volume, leading philosophers of psychiatry examine psychiatric classification systems, including the Diagnostic and Statistical Manual of Mental Disorders, asking whether current systems are sufficient for effective diagnosis, treatment, and research. Doing so, they take up the question of whether mental disorders are natural kinds, grounded in something in the outside world. Psychiatric categories based on natural kinds should group phenomena in such a way that they are subject to the same type of causal (...) explanations and respond similarly to the same type of causal interventions. When these categories do not evince such groupings, there is reason to revise existing classifications. The contributors all question current psychiatric classifications systems and the assumptions on which they are based. They differ, however, as to why and to what extent the categories are inadequate and how to address the problem. Topics discussed include taxometric methods for identifying natural kinds, the error and bias inherent in DSM categories, and the complexities involved in classifying such specific mental disorders as "oppositional defiance disorder" and pathological gambling. -/- Contributors George Graham, Nick Haslam, Allan Horwitz, Harold Kincaid, Dominic Murphy, Jeffrey Poland, Nancy Nyquist Potter, Don Ross, Dan Stein, Jacqueline Sullivan, Serife Tekin, Peter Zachar.

I argue that addiction is not an appropriate category to support generalizations for the purposes of scientific prediction. That is, addiction is not a natural kind. I discuss the Homeostatic Property Cluster (HPC) theory of kinds, according to which members of a kind share a cluster of properties generated by a common mechanism or set of mechanisms. Leading accounts of addiction in literature fail to offer a mechanism that explains addiction across substances. I discuss popular variants of the (...) disease conception and demonstrate that at least one class of substances that fails to confirm a major prediction of each account. When no mechanism can be found to explain the occurrence of the relevant properties in members of a category, the HPC view suggests that we revise our categories. I discuss options offered by the HPC view, including category revision and category replacement. I then conclude that talk of addiction as a prediction-supporting category should be replaced with categories such as “S-addiction” and “T-addiction,” where S and T are substances or sets of substances of abuse, as these categories are genuine natural kinds.

Jonathan Y. Tsou examines and defends positions on central issues in philosophy of psychiatry. The positions defended assume a naturalistic and realist perspective and are framed against skeptical perspectives on biological psychiatry. Issues addressed include the reality of mental disorders; mechanistic and disease explanations of abnormal behavior; definitions of mental disorder; natural and artificial kinds in psychiatry; biological essentialism and the projectability of psychiatric categories; looping effects and the stability of mental disorders; psychiatric classification; and (...) the validity of the DSM's diagnostic categories. The main argument defended by Tsou is that genuine mental disorders are biological kinds with harmful effects. This argument opposes the dogma that mental disorders are necessarily diseases that result from biological dysfunction. Tsou contends that the broader ideal of biological kinds offers a more promising and empirically ascertainable naturalistic standard for assessing the reality of mental disorders and the validity of psychiatric categories.

The notion of 'natural kinds' has been central to contemporary discussions of metaphysics and philosophy of science. Although explicitly articulated by nineteenth-century philosophers like Mill, Whewell and Venn, it has a much older history dating back to Plato and Aristotle. In recent years, essentialism has been the dominant account of natural kinds among philosophers, but the essentialist view has encountered resistance, especially among naturalist metaphysicians and philosophers of science. Informed by detailed examination of classification in the (...) natural and social sciences, this book argues against essentialism and for a naturalist account of natural kinds. By looking at case studies drawn from diverse scientific disciplines, from fluid mechanics to virology and polymer science to psychiatry, the author argues that natural kinds are nodes in causal networks. On the basis of this account, he maintains that there can be natural kinds in the social sciences as well as the natural sciences. (shrink)

The Nature of Classification discusses an old and generally ignored issue in the philosophy of science: natural classification. It argues for classification to be a sometimes theory-free activity in science, and discusses the existence of scientific domains, theory-dependence of observation, the inferential relations of classification and theory, and the nature of the classificatory activity in general. It focuses on biological classification, but extends the discussion to physics, psychiatry, meteorology and other special sciences.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.3 (2002) 237-241 [Access article in PDF] Practical, Functional, and Natural Kinds Nick Haslam Keywords: Classification, essentialism, natural kinds, practical kinds. I am grateful to the two commentators for giving my paper their serious attention, and for writing such stimulating, clarifying, and challenging responses. In a brief response I can only begin to discuss a select few issues, although (...) both commentaries could generate a great deal of profitable exchange.Zachar's commentary elaborates his practical kinds model, discusses several of the graded series of kinds proposed in my taxonomy of psychiatric categories, and disputes some aspects of my treatment of natural kinds. Zachar and I have no quarrel on his first point. I recognize his practical kinds model as a general theory of psychiatric classification rather than simply as a description of one type of category, the "practical kind." It was perhaps bad form to pilfer a term from Zachar's model and give it a more circumscribed role in my own, although by doing so I intended both to acknowledge the importance of the concept and to situate it among some of its alternatives.All the same, I stand by the account of practical kinds developed in my paper, even if it reflects a narrower sense than Zachar's. In my sense, practical kinds are pragmatically drawn distinctions imposed on continuous dimensions, whereas to Zachar all psychiatric categories are at least to some degree practical. He therefore proposes a broad "continuum" of practical kinds. The difficulty that I have with this proposal is that such a continuum implies a fundamental unity among psychiatric categories: categories are all to be understood first and foremost in pragmatic terms and differences in kind between them in internal structure are to be neglected. In my view, although the pragmatic bases of psychiatric classification are vitally important, and perhaps inadequately formulated in my paper, the neglect of internal structure and of possible breaks in the continuum of kinds are real limitations of the practical kinds model. Although Zachar is partially justified in claiming that his view is pluralistic, allowing as it does for variability in degrees of practicality, by failing to acknowledge distinctly different kinds of categories in the psychiatric domain, his view is less pluralistic than I believe it should be.One example of what I take to be this neglect of structural differences is a conflation of two sorts of practicality in Zachar's work. On the one hand, certain categories such as hypertension or obesity are defined on pragmatic grounds, a binary distinction being drawn in the absence of an internal discontinuity, because individuals identified as category members are adjudged to [End Page 237] be at significantly elevated risk. On the other hand, some categories just happen to have high practical utility. Zachar argues that schizotaxia, for example, is practical because it affords a variety of scientific and clinical inferences.It seems to me that these sorts of practicality—or perhaps these sorts of relations to practicality—are importantly different. Hypertension is defined as a category because of its practical utility—because a certain blood pressure threshold marks an inflection in actuarial risk of other illnesses—and might therefore be said to have "front-end" or constitutive practicality. Schizotaxia, which taxometric research shows to be a discrete kind (Haslam, 2003), is not defined and identified primarily on the basis of its relation to an external criterion, but on the basis of its internal structure. Its features cohere in a way that indicates a category with a determinate prevalence. It has "back-end" or consequential practicality to the degree that this category enables useful predictions. These two proposed forms of practicality are equally important: both mean that categories will be pragmatically valuable. However, they are also different, being characteristic of different kinds of categories and perhaps even negatively related. Kinds with front-end practicality, that is, may tend to have a more restricted range of practical implications, defined as they are in relation to specific external criteria. Kinds with back-end practicality, in contrast, may enable a wider array of predictions to the extent that... (shrink)

How are we to understand the phenomenology of imagining? Attempts to answer this question often invoke descriptors concerning the “vivacity” or “vividness” of our imaginative states. Not only are particular imaginings often phenomenologically compared and contrasted with other imaginings on grounds of how vivid they are, but such imaginings are also often compared and contrasted with perceptions and memories on similar grounds. Yet however natural it may be to use “vividness” and cognate terms in discussions of imagination, it does (...) not take much reflection to see that these terms are ill understood. In this paper, I review both some relevant empirical literature as well as the philosophical literature attempt to get a handle on what it could mean, in an imaginative context, to talk of vividness. As I suggest, this notion ultimately proves to be so problematic as to be philosophically untenable. (shrink)

Underlying much current work in philosophy of imagination is the assumption that imagination is a skill. This assumption seems to entail not only that facility with imagining will vary from one person to another, but also that people can improve their own imaginative capacities and learn to be better imaginers. This paper takes up this issue. After showing why this is properly understood as a philosophical question, I discuss what it means to say that one imagining is better than another (...) and then discuss the kinds of imagination training and techniques that might be employed in an effort to get better at imagining. The discussion of these techniques draws insight from consideration of other skills-based activities, as well as from consideration of the creation of art and our engagement with literature and poetry. Over the course of this discussion, we also gain further insight into the nature of imagination. (shrink)

Gupta and L. Rex Kay Keywords: behavior, empathy, human science, methodology, natural science, phenomenology. WE ARE GRATEFUL to the journal for prviding the opportunity for exchange and discussion of some of the themes raised in our paper, "The impact of phenomenology on North American psychiatric assessment" and (...) we are pleased to be able to reply to the two excellent commentaries by McMillan and Morley. Both McMillan and Morley question the prospect of employing phenomenology and its methods in psychiatric assessment, and in psychiatric practice more generally. McMillan questions the utility of such a step, and Morley is pessimistic about its feasibility. We shall address each author's concerns in turn.Initially, let us restate the aims of our paper to contextualize our arguments and those made in the commentaries. First, we sought an understanding of what is meant by North American psychiatrists, working within the DSM framework, when they refer to the phenomenological approach to psychiatric assessment. To elucidate this meaning, we compared the contemporary North American usage to a small number of definitions of phenomenology, particularly those definitions that were, and are now, applied to clinical psychiatric work. Contrary to McMillan's suggestion, we did not intend to state definitively what should or should not count as phenomenological, but rather to compare North American psychiatric assessment to what typically has counted as phenomenological. Second, we sought to examine phenomenology's influence on North American psychiatric practice, particularly psychotherapy.Morley argues that such influences usually exemplify the inappropriate appending of phenomenology to psychiatric practice rather than true integration of different paradigms. Although we do not disagree with this general contention, we will argue that the deployment of phenomenological methods in psychiatric assessment is a necessary first step toward the kind of integration he proposes.McMillan makes two related but unintegrated points. First, he argues that objective, behavioral data are phenomenological, according to his broad definition of the term. Second, he proposes that, if the behavioral and the phenomenological are different, we are better off staying with the behavioral when it comes to psychiatric nosology. Let us consider these two points in succession.McMillan seeks to broaden Jasper's definition of phenomenology to include objective observations [End Page 93] as phenomenological. To this end, he distinguishes methods from aims. He summarizes Jasper's definition of phenomenology as "an empirical method for investigating 'individual psychic experience (p 55)" and claims that this is a statement of aim or objectives. He then urges us to "consider the merits of different phenomenological methodologies in terms of their success in achieving this objective" whether or not they utilize "all the methods" of phenomenology. This is much like saying that if we treat waving one's hand as a method for greeting someone, we are then free to treat the objective of the wave as one of greeting someone, and then say that anything that serves as a greeting is, by definition, a "wave." Whatever else McMillan's objective observations are, he has not convinced us that they are phenomenological, anymore than we are likely to convince you that a kiss on the lips is really just a wave.Nonetheless, it is worthwhile seeing what McMillan does with this argument. He tells us that we can "read the first-person experience from behavior in a fairly accurate and informative way." He uses the example of a father gazing at his young child and notes that it is not unreasonable to infer that he is experiencing loving and nurturing feelings. It is, indeed, not unreasonable to draw such an inference. But it is far more reasonable to infer that the father is experiencing a cacophony of feelings, including, but not limited to, love, concern, anxiety, pride, envy, hope, and sadness (Stern 1995, 18-58). If we are able to distinguish which of these feelings is dominant at any given moment—which we are—and if we are also able to track subtle shifts in such feelings... (shrink)

Tilmes concludes his interesting and informative piece with the sentence that “analysis of psychiatric vagueness merits further consideration.” I agree with this point, as well as with his earlier assertion that how one understands psychiatric vagueness may implicate the diagnostic model that one adopts, and the research that one pursues.

Vagueness in psychiatry is related to a range of nosological debates, including about (...) the... (shrink)

In this Element, we’ll explore the nature of both imagination and creative thinking in an effort to understand the relation between them and also to understand their role in the vast array of activities in which they are typically implicated, from art, music, and literature to technology, medicine, and science. Focusing on the contemporary philosophical literature, we will take up several interrelated questions: What is imagination, and how does it fit into the cognitive architecture of the mind? What is creativity? (...) Is imagination required for creativity? Is creativity required for imagination?

As persons, we are importantly different from all other creatures in the universe. But in what, exactly, does this difference consist? What kinds of entities are we, and what makes each of us the same person today that we were yesterday? Could we survive having all of our memories erased and replaced with false ones? What about if our bodies were destroyed and our brains were transplanted into android bodies, or if instead our minds were simply uploaded to computers? (...) -/- In this engaging and accessible introduction to these important philosophical questions, Amy Kind brings together three different areas of research: the nature of personhood, theories of personal identity over time, and the constitution of self-identity. Surveying the key contemporary theories in the philosophical literature, Kind analyzes and assesses their strengths and weaknesses. As she shows, our intuitions on these issues often pull us in different directions, making it difficult to develop an adequate general theory. Throughout her discussion, Kind seamlessly interweaves a vast array of up-to-date examples drawn from both real life and popular fiction, all of which greatly help to elucidate this central topic in metaphysics. -/- A perfect text for readers coming to these issues for the first time, Persons and Personal Identity engages with some of the deepest and most important questions about human nature and our place in the world, making it a vital resource for students and researchers alike.

One common response to the knowledge argument is the ability hypothesis. Proponents of the ability hypothesis accept that Mary learns what seeing red is like when she exits her black-and-white room, but they deny that the kind of knowledge she gains is propositional in nature. Rather, she acquires a cluster of abilities that she previously lacked, in particular, the abilities to recognize, remember, and imagine the color red. For proponents of the ability hypothesis, knowing what an experience is like simply (...) consists in the possession of these abilities. Criticisms of the ability hypothesis tend to focus on this last claim. Such critics tend to accept that Mary gains these abilities when she leaves the room, but they deny that such abilities constitute knowledge of what an experience is like. To my mind, however, this critical strategy grants too much. Focusing specifically on imaginative ability, I argue that Mary does not gain this ability when she leaves the room for she already had the ability to imagine red while she was inside it. Moreover, despite what some have thought, the ability hypothesis cannot be easily rescued by recasting it in terms of a more restrictive imaginative ability. My purpose here is not to take sides in the debate about physicalism, i.e., my criticism of the ability hypothesis is not offered in an attempt to defend the anti-physicalist conclusion of the knowledge argument. Rather, my purpose is to redeem the imagination from the misleading picture of it that discussion of the knowledge argument has fostered. (shrink)

Not all imaginings are successful; sometimes when an imaginer sets out to imagine some target, her imagining involves some kind of mistake. The error can be diagnosed in two ways: the imaginer imagines her target in a way that mischaracterizes it, or the imaginer fails to imagine her target at all and rather imagines something else that is similar in some ways to that target. In ordinary day-to-day imaginings, explanations of type seem most natural, but in discussions of philosophical (...) imaginings, philosophers tend to adopt explanations of type. This paper argues against this tendency. (shrink)

As we await the increasingly likely advent of genuinely intelligent artificial systems, a fair amount of consideration has been given to how we humans will interact with them. Less consideration has been given to how—indeed if—we humans will love them. What would human-AI romantic relationships look like? What do such relationships tell us about the nature of love? This chapter explores these questions via consideration of several works of science fiction, focusing especially on the Black Mirror episode “Be Right Back” (...) and the Spike Jonze's movie *Her*. As I suggest, there may well be cases where it is both possible and appropriate for a human to fall in love with a machine. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Imagination in Inquiry by A. Pablo IannoneAmy KindIANNONE, A. Pablo. Imagination in Inquiry. Lanham, Md.: Lexington Books, 2022. xxvi + 254 pp. Cloth, $110.00; eBook $45.00Though imagination is often associated with the fanciful and the fictional, over the course of the last decade philosophers have begun to devote considerable attention to more practical uses of imagination. Philosophers of imagination have increasingly focused on ways in which imagination can (...) play an important epistemic role in activities such as decision-making, planning, and scientific discovery; more generally, there has been attention to a variety of ways in which imagination can teach us about the world in which we live. Iannone’s discussion in Imagination in Inquiry can be seen as part of this general trend—even if his discussion is not itself situated directly within contemporary philosophy of imagination but, rather, in a broader interdisciplinary approach.Iannone works with an expansive conception of what imagination is. In his view, we should not limit our understanding of imagination simply to the ability to generate images. Rather, imagination is a diverse set of different abilities that aim “at figuring out cognitively, emotively, or practically, alternatives for dealing with actual, probable, plausible, foreseeable, or merely possible challenges or problems, abstract or concrete, theoretical or practical being faced, or notions being considered, and determining or deciding which is (are) preferable in the circumstances, and acting accordingly.” Moreover, this set of abilities should not be seen as operating in isolation; rather, imagination functions as part of an ecology of human abilities. Iannone refers to his view of imagination as the “homeostatic model,” so called because he sees imaginative processes as maintaining stability by way of a system of self-correcting feedback and methods for incorporating and adjusting to any new information received.Iannone also operates with an expansive conception of what counts as practical use of imagination. In his view, imagination is put to practical use in a wide range of circumstances, for example, when a dancer imagines the next steps of a dance in the process of spontaneous improvising, when a combatant imagines how to block an expected blow from an opponent, and when an environmental activist imagines a new set of corrective policies to address pollution. All these uses fall under the activity of what Iannone calls “inquiry,” that is, the activity of finding a solution to a problem or challenge. The problems and challenges that might prompt the use of imagination can be both personal and interpersonal, and the imaginative processes used will involve strategies such as discovery, creation, and anticipation.In the first part of the book, Iannone develops his basic conceptual apparatus. In the next part of the book, he puts this apparatus to work in the context of philosophy, that is, he shows how imagination plays a role in philosophical inquiry. In the third part of the book, he looks at the role of imagination in other disciplines such as sociology and psychology. Here, the interdisciplinary nature of his discussion is especially on display. In the fourth part of the book, he applies his model of imagination to a number of different contexts; in particular, he discusses the role of [End Page 354] imagination in language, in humor, in vision (both at the personal and the societal level), and in morality. Finally, the last part of the book offers a variety of case studies involving dance, technology, and artificial intelligence. Of the four chapters in this part of the book, three are written by other authors: two by Alejandra Iannone, a scholar and practitioner of dance and theater (and the author’s daughter), and one by Rocci Luppicini, an expert in technology studies. In light of the explosive pace with which new AI technologies are being developed, the book’s discussion of whether and how such technologies present challenges for our capacity for imagination is especially timely and important.In addition to affirming the practical importance of imagination, Iannone also affirms the practical importance of nurturing imagination—something he repeats at several points throughout the book. But how do we do this? One natural way that imagination is nurtured is simply by its regular use... (shrink)

Both imagery and imagination play an important part in our mental lives. This article, which has three main sections, discusses both of these phenomena, and the connection between them.

The second part turns to the faculty of the imagination, discussing the long philosophical tradition linking mental imagery and the imagination—a tradition that came under attack in the (...) early part of the twentieth century with the rise of behaviorism. Finally, the third part of this article examines modal epistemology, where the imagination has been thought to serve an important philosophical function, namely, as a guide to possibility. (shrink)

Philosophers have long suggested that our attitude of special concern for the future is problematic for a reductionist view of personal identity, such as the one developed by Derek Parfit in Reasons and Persons. Specifically, it is often claimed that reductionism cannot provide justification for this attitude. In this paper, I argue that much of the debate in this arena involves a misconception of the connection between metaphysical theories of personal identity and our special concern. A proper understanding of this (...) connection reveals that the above-mentioned objection to reductionism cannot get off the ground. Though the connection I propose is weaker than the connection typically presupposed, I nonetheless run up against a conclusion reached by Susan Wolf in “Self-Interest and Interest in Selves.” According to Wolf, metaphysical theses about the nature of personal identity have no significance for our attitude of special concern. By arguing against Wolf’s treatment of self-interest, I suggest that her arguments for this conclusion are misguided. This discussion leads to further clarification of the nature of the link between theories of personal identity and our special concern and, ultimately, to a better understanding of the rationality of this attitude.

Among the many commonalities between memory and imagination is the fact that they can both be understood as skills. In this chapter, I aim to draw out some connections between the skill of memory and the skill of imagination in an effort to learn something about the nature of these activities and the connection between them. I start by considering the ways that one might work to cultivate these skills in the hope that we could learn something about imagination training (...) by reflection on memory training and vice versa. Interestingly, however, an initial look at the empirical research on the respective training regimens does not show much potential for this kind of crossover. Though there are some commonalities that can be found across the training regimens, these commonalities are nothing special over and above the kinds of commonalities one might find in training regimens for skills of any sort. Fortunately, however, the matter does not end there. When we think more deeply about the details of some of the training regimens for memory, we discover some important connections between the skill of memory and the skill of imagination. In particular, I argue that the two skills turn out to be interestingly intertwined. (shrink)

__: In this essay I explore the account of imaginative phenomenology developed by Uriah Kriegel in _The Varieties of Consciousness_. On his view, the difference between perceptual phenomenology and imaginative phenomenology arises from the way that they present the existential status of their object: While perceptual experience presents its object as existent, imaginative experience presents its object as non-existent. While I agree with Kriegel that it’s likely that the difference between imaginative phenomenology and perceptual phenomenology is one not just of (...) degree but of kind, I worry about the particular account that he has developed. I thus develop two lines of criticism. First, I question whether Kriegel is right that imagination presents its object as non-existent. Second, I question whether this account of imaginative phenomenology is consistent with other commonly-accepted facts about the nature of imagination. _Keywords_: Imagination; Perception; Phenomenology; J.-P. Sartre; Epistemic Value; Emotion ___Fenomenologia dell’immaginazione e status esistenziale_ _Riassunto_: In questo articolo intendo indagare l’approccio alla descrizione della fenomenologia dell’immaginazione sviluppata da Uriah Kriegel in _The Varieties of Consciousness_. Dal suo punto di vista, la differenza tra fenomenologia della percezione e fenomenologia dell’immaginazione si mostra nel modo in cui queste presentano lo status esistenziale dei loro oggetti: se l’esperienza percettiva presenta il proprio oggetto come esistente, l’esperienza immaginativa lo presenta come non-esistente. Per un verso, concordo con Kriegel sulla probabilità che la differenza tra fenomenologia dell’immaginazione e fenomenologia della percezione non sia di grado ma di genere, mentre, per altro verso, non sono convinta della correttezza del suo approccio. Pertanto vorrei sollevare due criticità. In primo luogo, mi chiedo se Kriegel sia nel giusto quando ritiene che l’immaginazione presenti il proprio oggetto come non-esistente; in secondo luogo, mi chiedo se questa descrizione della fenomenologia dell’immaginazione sia coerente con altri fatti, comunemente accettati, circa la natura dell’immaginazione. _Parole chiave_: Immaginazione; Percezione; Fenomenologia; J.-P.

The traditional practice of establishing morphological types and investigating morphological organization has found new support from evolutionary developmental biology (evo-devo), especially with respect to the notion of body plans. Despite recurring claims that typology is at odds with evolutionary thinking, evo-devo offers mechanistic explanations of the evolutionary origin, transformation, and evolvability of morphological organization. In parallel, philosophers have developed non-essentialist conceptions of natural kinds that permit kinds to exhibit variation and undergo change. This not only facilitates a (...) construal of species and higher taxa as natural kinds, but also broadens our perspective on the diversity of kinds found in biology. There are many different natural kinds relevant to the investigative and explanatory aims of evo-devo, including homologues and developmental modules. (shrink)

An important question in the philosophy of psychiatry is: what is the proper method of psychiatric diagnostic reasoning? Let us call this the Methodological Question. In this paper, I criticize the answer that proponents of phenomenological psychiatry have given to this question and present an alternative. I argue that their answer fails to meet several adequacy conditions for a theory of psychiatric diagnostic reasoning. I then show how my own answer to the Methodological Question – the Model-Based Account (...) of diagnostic reasoning – meets these adequacy conditions. I conclude that the Model-Based Account of diagnostic reasoning is preferable to the Phenomenological Account. (shrink)

We examine the philosophical and empirical issues related to the question whether psychopathy can be considered a psychiatric natural kind. Natural kinds refer to categories that are privileged because they the capture certain real divisions in nature. Generally, in philosophical debates regarding psychiatry, there is much scepticism about the possibility that psychiatric categories track natural kinds. We outline the main positions in the debate about natural kinds in psychiatry and examine whether (...) psychopathy can be considered as a natural kind on any of the proposed accounts. By examining the scientific literature on psychopathy, we draw two main conclusions: (1) the empirical data currently do not support the view that this condition is unified enough to be considered a natural kind; (2) the construct of psychopathy plays useful roles both in the context of scientific research and in forensic and clinical settings. These considerations bring us to our tentative conclusion about psychopathy as a kind in the making, a sort of “under construction” category with potential for improvement and refinement with further research.

A significant portion of the scholarship in analytic philosophy of psychiatry has been devoted to the problem of what kind of kind psychiatric disorders are. Efforts have included descriptive projects, which aim to identify what psychiatrists in fact refer to when they diagnose, and prescriptive ones, which argue over that to which diagnostic categories should refer. In other words, philosophers have occupied themselves with what I call “diagnostic kinds”. However, the pride of place traditionally given to diagnostic (...) class='Hi'>kinds in psychiatric research has recently come under attack, most notably by a recent initiative of the National Institute of Mental Health, the Research Domain Criteria Project, that seeks to exclude diagnostic categories from experimental designs and focus on other sorts of psychiatric kinds. I argue that philosophical accounts privileging diagnostic kinds must respond to this new line of criticism, and conclude that philosophers need to either counter psychiatrists’ growing suspicion about the hegemony of diagnostic categories in the clinic and the laboratory, or join in redirecting their efforts toward the development of robust accounts of other sorts of psychiatric objects and processes.

How do-or how should-we parse the world into kinds of things? Going back at least to Plato, most philosophers have done so with respect to some notion or other of natural kinds. And many analyses of natural kinds have been essentialistic-that is defining those kinds with respect to universals, or some set of intrinsic properties, or necessary and sufficient conditions. And there's a long-standing dispute between thinkers who regard scientific categories as natural (...) class='Hi'>kinds with essential properties fixed by nature-those that "cut nature at its joints"-and thinkers who maintain that our classifications and categories have no essence and instead merely reflect human interests and values. A typical example of the former would be "having a mass of 1.7 × 10-27," and examples of the latter would be the categories of "ADHD," "race," or "child abuse." Khalidi aims for an epistemic, naturalistic, non-essentialist, account of natural kinds, one which comfortably embraces not only the usual candidates favored by essentialists (e.g., elementary particles, chemical elements, biological species), but also categories in the social and behavioral sciences. Drawing on cases from many scientific fields, from fluid mechanics and polymer science to virology and psychiatry, Khalidi argues that "natural kinds are investigative or epistemic kinds, in the sense that they are the categories revealed by our systematic attempts to gain knowledge of nature" (p. 43). Moreover, he claims that natural kinds can be "fuzzy" (i.e. have indefinite boundaries), satisfy epistemic virtues to varying degrees, and be mind-dependent in a way that doesn't detract from their reality or objectivity. Although the book is pitched for a sophisticated and philosophically informed audience (and, needless to say, too complex to be adequately summarized in a brief notice such as this), it's clearly written, nuanced, compellingly argued, and worth the effort for JSE readers curious about the unavoidable metaphysical dimensions of doing science of any kind.

Despite the traditional focus on metaphysical issues in discussions of natural kinds in biology, epistemological considerations are at least as important. By revisiting the debate as to whether taxa are kinds or individuals, I argue that both accounts are metaphysically compatible, but that one or the other approach can be pragmatically preferable depending on the epistemic context. Recent objections against construing species as homeostatic property cluster kinds are also addressed. The second part of the paper broadens (...) the perspective by considering homologues as another example of natural kinds, comparing them with analogues as functionally defined kinds. Given that there are various types of natural kinds, I discuss the different theoretical purposes served by diverse kind concepts, suggesting that there is no clear-cut distinction between natural kinds and other kinds, such as functional kinds. Rather than attempting to offer a unique metaphysical account of ‘natural’ kind, a more fruitful approach consists in the epistemological study of how different natural kind concepts are employed in scientific reasoning.

The notion of 'natural kinds' has been central to contemporary discussions of metaphysics and philosophy of science. In recent years, essentialism has been the dominant account of natural kinds among philosophers, but the essentialist view has encountered resistance. Informed by detailed examination of classification in the natural and social sciences, Prof. Muhammad Ali Khalidi argues against essentialism and for a naturalist account of natural kinds. By looking at case studies drawn from diverse scientific (...) disciplines, from fluid mechanics to virology and polymer science to psychiatry, the author argues that natural kinds are nodes in causal networks. On the basis of this account, he maintains that there can be natural kinds in the social sciences as well as the natural sciences. (shrink)

Carruthers’s central project in Phenomenal Consciousness is to naturalize consciousness. Given the vast success of naturalism in science, he maintains that we should require powerful reasons to abandon it when constructing philosophical theories of consciousness. Unsurprisingly, he then argues that there are no such reasons. In particular, he claims that the well-known arguments of Thomas Nagel and Frank Jackson fail, as do inverted and absent qualia arguments. Carruthers’s main strategy for defusing these arguments involves first distinguishing a “thin” notion of (...) property from a “thick” notion of property and then arguing that the various antinaturalistic arguments conflate these two different notions. Although he admits that the antinaturalist may not find these considerations wholly convincing, he construes the dialectical situation in such a way as to relieve him of any obligation to do more. As long as it can be shown that the antinaturalistic arguments are not obviously successful, which he takes himself to have done, Carruthers claims that the presumption in favor of naturalism remains. Thus, a theory of consciousness must be compatible with the following two naturalistic claims: first, all mental events occur in accordance with causal laws; and second, all mental events can be given a reductive explanation in physical terms.

It is commonly held that objects in the world form natural kinds. Rabbits form a natural kind and so do all pieces of gold. The traditional account of natural kinds asserts that the members of a kind share a common essence. The essence of gold, for example, is its unique atomic structure. That structure occurs in all and only pieces of gold, and it is a property that all pieces of gold must have.

This article, which is intended both as a position paper in the philosophical debate on natural kinds and as the guest editorial to this thematic issue, takes up the challenge posed by Ian Hacking in his paper, “Natural Kinds: Rosy Dawn, Scholastic Twilight.” Whereas a straightforward interpretation of that paper suggests that according to Hacking the concept of natural kinds should be abandoned, both in the philosophy of science and in philosophy more generally, we (...) suggest that an alternative and less fatalistic reading is also possible. We argue that abandoning the concept of natural kinds would be premature, as it still can do important work. Our concern is with the situation in the (philosophy of the) life sciences. Against the background of this concern we attempt to set something of an agenda for future research on the topic of natural kinds in the (philosophy of the) life sciences. (shrink)

RésuméLes concepts de Ian Hacking ont apporté une contribution importante aux débats dans le domaine de la philosophie de la psychiatrie, qui est aussi au coeur de son Cours au Collège de France. Titulaire de la « Chaire de philosophie et d’histoire des concepts scientifiques » après Michel Foucault, il est l’auteur d’une réflexion sur la classification des troubles mentaux à partir de la problématique des natural kinds. Pour expliquer les cas d’études développés dans son enseignement parisien, nous (...) revenons d’abord sur une série de concepts, pour ensuite poser la question du statut des métaphores scientifiques, et enfin discuter les rapports entre les notions de « maladie mentale transitoire » et de culture-bound syndrome – cette dernière étant issue de la psychiatrie transculturelle canadienne.

Despite how he begins, suggesting that it is somehow a problem for me that I think "there is such a thing as philosophy, which could then be useful for psychopathology," ultimately it is clear that the possibility of philosophy is not the issue for Ghaemi. Rather, his issue is with academic philosophy of psychiatry, as he sees it, and with my failure to ask what underlying assumptions typically operate in it.I do not dispute that someone like Jaspers would want (...) to ask such a question, nor do I dispute that it is, in general, a perfectly good question. But Ghaemi thinks that my paper is missing out on something by not posing it. The reason he thinks this is because he thinks my paper is an instance of a pattern in the discipline against which he evidently has an axe to grind. In particular, he thinks philosophy in general should be more attendant to the ways in which Diagnostic and Statistical Manual of Mental Disorders (DSM) categories are (problematically) socially constructed. The fact that philosophers have failed to critically point this out allegedly shows philosophy of psychiatry's— and my—unexamined sympathy with the postmodern tendencies—understood as tendencies toward "relativism about truth" and "skepticism about science"—of psychiatry itself. This is odd for a number of reasons, especially in the present context. Firstly, I am not presently in a position to exhaustively defend all of philosophy of psychiatry on the charge of 'postmodernism,' or on the charge of failure to critically engage with the DSM, but it is worth simply stating that I find these to be rather patently unsubstantiated charges. Prominent works that falsify the latter and easily come to mind are by Tsou (2011), Cooper (2004, 2007), Horwitz and Wakefield (2007), Murphy (2006), Poland and von Eckhardt (2013), and Lalumera (2016). Of these, only Lalumera is interested in defending a DSM-style descriptivism (which perhaps Ghaemi would call a kind of "social constructionism"), but even she limits her defense of DSM categories to their role as reference-fixing representations. It is also true that Tsou's paper is an argument that the practical considerations which go into shaping the DSM categories sometimes represent values that permissibly operate in psychiatry. Perhaps this could be construed as a kind of social constructionism as well, and presumably Ghaemi would disagree with it, but no one here is guilty of a failure to engage critically with the DSM and its history. Further, whichever position is taken by these theorists on whether the DSM does, or even one day could, cut nature at its joints, or whether some of the values that shape its construction do so permissibly or impermissibly, one's acceptance or rejection of relativism about truth is an entirely logically independent matter.

A large part of the controversy surrounding the publication of DSM-5 stems from the possibility of replacing the purely descriptive approach to classification favored by the DSM since 1980. This paper examines the question of how mental disorders should be classified, focusing on the issue of whether the DSM should adopt a purely descriptive or theoretical approach. I argue that the DSM should replace its purely descriptive approach with a theoretical approach that integrates causal information into the DSM’s descriptive diagnostic (...) categories. The paper proceeds in three sections. In the first section, I examine the goals (viz., guiding treatment, facilitating research, and improving communication) associated with the DSM’s purely descriptive approach. In the second section, I suggest that the DSM’s purely descriptive approach is best suited for improving communication among mental health professionals; however, theoretical approaches would be superior for purposes of treatment and research. In the third section, I outline steps required to move the DSM towards a hybrid system of classification that can accommodate the benefits of descriptive and theoretical approaches, and I discuss how the DSM’s descriptive categories could be revised to incorporate theoretical information regarding the causes of disorders. I argue that the DSM should reconceive of its goals more narrowly such that it functions primarily as an epistemic hub that mediates among various contexts of use in which definitions of mental disorders appear. My analysis emphasizes the importance of pluralism as a methodological means for avoiding theoretical dogmatism and ensuring that the DSM is a reflexive and self-correcting manual. (shrink)

Evolutionary developmental biologists categorize many different kinds of things, from ontogenetic stages to modules of gene activity. The process of categorization—the establishment of “kinds”—is an implicit part of describing the natural world in consistent, useful ways, and has an essentially practical rather than philosophical basis. Kinds commonly serve one of three purposes: they may function (1) as practical tools for communication; (2) to support prediction and generalization; or (3) as a basis for theoretical discussions. Beyond the (...) minimal requirement that classifications reflect biological reality, what sorts of kinds or classification will be useful in advancing a research program depends on the epistemological context. Thus, the important meaning of “natural” in “natural kinds” is not “natural with respect to nature,” but “natural with respect to the question.” This conclusion arises from the recognition that the proper role of concepts (e.g. natural kind, module, homology, model) is not to answer biological questions, but rather to help frame them. From a scientist’s perspective, arguing about the wording (or existence) of a single definition of “natural” or “kind” is beside the point: we get more work done by letting the question at hand determine what kinds of kinds are natural, on the basis of their ability to help answer it. We should be content to let “natural kinds” remain vague, multivalent, and–therefore broadly useful. For a philosopher like Hacking, the diverse, disparate, and ultimately incommensurable uses of the term “natural kind” have diluted its value so far that it loses all meaning. For practicing scientists, however, defining useful kinds in the context of particular questions and systems remains a productive epistemological strategy. (shrink)

The aim of this paper is to analyze, from a philosophical perspective, the scientific robustness of the construct of psychopathy as measured by the Psychopathy Checklist Revised that was developed by Robert Hare (1991; 2003). The scientific robustness and validity of classifications are topics of many debates in philosophy of science and philosophy of psychiatry more specifically. The main problem consists in establishing whether scientific classifications reflect natural kinds where the concept of a natural kind refers (...) to the existence of some objective divisions in nature that do not depend exclusively on subjective judgments of the classifier. The construct of psychopathy is especially interesting since the diagnosis of psychopathy has substantial social consequences. In the light of the recent debates regarding the problem of natural kinds in philosophy of psychiatry, we advocate the following distinction between two types of scientific classifications: natural and practical kinds. Natural kinds refer to those categories that are united by common causal mechanisms or properties. Practical kinds refer to categories that fulfill some practical classificatory goals such as prediction. We argue that the construct of psychopathy can fulfill the role of a practical kind. In addition, we contend that our current scientific knowledge about psychopathy does not allow us to conclude that this category is a natural kind. (shrink)

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders was published in 2013. This manual classifies all known mental disorders and provides operationalized criteria for their diagnosis. The goal of this manual is to facilitate communication, treatment and research with reliable and valid diagnoses. This article will provide a study of what this diagnostic validity actually entails. Firstly, it will include a discussion of the different conceptions of validity that have appeared in the literature so far. To (...) decide between these different conceptions, diagnostic validity will be defined as ”picking out a natural kind’. Secondly, two different accounts of natural and psychiatric kinds are examined, namely, essentialism and pragmatism. Both of these will be rejected in favor of conceiving natural kinds as causal-epistemic kinds. Thirdly, it is argued that the multidimensional complexity of psychiatric disorders does not exclude the possibility of psychiatric kinds being natural kinds. However, pragmatic considerations in classifying disorders have meant that the DSM most likely does not distinguish causal-epistemic kinds very well. I argue that the need to have a single classification both for clinicians and researchers and the priority given to reliability rather than validity has ultimately compromised the diagnostic validity of the DSM.

Scientists cannot devise theories, construct models, propose explanations, make predictions, or even carry out observations, without first classifying their subject matter. The goal of scientific taxonomy is to come up with classification schemes that conform to nature's own. Another way of putting this is that science aims to devise categories that correspond to 'natural kinds.' The interest in ascertaining the real kinds of things in nature is as old as philosophy itself, but it takes on a different (...) guise when one adopts a naturalist stance in philosophy, that is when one looks closely at scientific practice and takes it as a guide for identifying natural kinds and investigating their general features. This Element surveys existing philosophical accounts of natural kinds, defends a naturalist alternative, and applies it to case studies in a diverse set of sciences. This title is also available as Open Access on Cambridge Core. (shrink)

This edited volume of 13 new essays aims to turn past discussions of natural kinds on their head. Instead of presenting a metaphysical view of kinds based largely on an unempirical vantage point, it pursues questions of kindedness which take the use of kinds and activities of kinding in practice as significant in the articulation of them as kinds. The book brings philosophical study of current and historical episodes and case studies from various scientific disciplines (...) to bear on natural kinds as traditionally conceived of within metaphysics. Focusing on these practices reveals the different knowledge-producing activities of kinding and processes involved in natural kind use, generation, and discovery. -/- Specialists in their field, the esteemed group of contributors use diverse empirically responsive approaches to explore the nature of kindhood. This groundbreaking volume presents detailed case studies that exemplify kinding in use. Newly written for this volume, each chapter engages with the activities of kinding across a variety of disciplines. Chapter topics include the nature of kinds, kindhood, kinding, and kind-making in linguistics, chemical classification, neuroscience, gene and protein classification, colour theory in applied mathematics, homology in comparative biology, sex and gender identity theory, memory research, race, extended cognition, symbolic algebra, cartography, and geographic information science. -/- The volume seeks to open up an as-yet unexplored area within the emerging field of philosophy of science in practice, and constitutes a valuable addition to the disciplines of philosophy and history of science, technology, engineering, and mathematics. -/- Contributions from a diverse group of established and junior scholars in the fields of Philosophy and History and Philosophy of Science including Hasok Chang, Jordi Cat, Sally Haslanger, Joyce C. Havstad, Catherine Kendig, Bernhard Nickel, Josipa Petrunic, Samuli Pöyhönen, Thomas A. C. Reydon, Quayshawn Spencer, Jackie Sullivan, Michael Wheeler, and Rasmus Grønfeldt Winther. (shrink)

After the French Revolution, the codification movement led to the introduction of the Dutch Civil Code and the Commercial Code of 1838. These codifications were generally regarded as the bedrock of a dogmatic system in which little space was left for customs and customary law. Mercantile jurists, such as Holtius and Levy, were opponents of the legalistic approach of the new codifications. They tried to separate mercantile law from civil law in order to protect mercantile law from excessive legalistic influences. (...) According to them, mercantile law was characterised by internationality, custom as its main source of law, continuity through an extended mercantile legal history and by good faith and mutual trust between the merchants. Out of these, the historicity and homogeneity of a strong community of merchants are particularly in line with a traditional and conservative view on society. Holtius and Levy, however, had little in common with their Christian-conservative contemporaries. On the one hand, they rather seemed to foreshadow the kind of liberal-conservatism as expressed by Hayek during the 20th century. On the other hand, their ideas have much in common with different lex mercatoria –traditions developed by authors as Goldman and Schmitthoff. On the aspects of historicity and internationality Holtius and Levy seem to have much in common with Hayek whereas concerning communality and the legal nature of customary law there are more similarities with the lex mercatoria-traditions.

This thesis investigates the nature of psychiatric disorders, and to what extent they can form a basis for classification, explanation, and treatment interventions. These questions are important in the light of the “crisis of validity” in psychiatry, according to which current diagnostic categories do not pick out real disorders. I address the questions by defending an account of psychiatric disorders that can better accommodate social aspects and non-epistemic values than the symptom-based model of the Diagnostic and Statistical Manual of (...) Mental Disorders (DSM) and the brain disease model of the biomedical approach, including the Research Domain Criteria (RDoC). I concentrate on three ways that psychiatric disorders can differ from prototypical natural kinds, such as biological species and chemical elements. First, the concept of psychiatric disorder or mental disorder is partly value-laden and cannot be defined based only on scientific facts. Second, the objects of psychiatric classifications are interactive human kinds because people with disorders respond to their classifications through looping effects. Third, sociocultural factors can shape disorders in complex ways, which is indicated by their cross-cultural variation. I argue that these challenges can be overcome with a pluralistic explanatory account that grants an explicit role to value-sensitive considerations and social scientific research. Based on this, I argue that particular disorders can in principle support inductive inferences. ------------------------------------------------------------------------------------------ My key argument is that although whether a condition is considered pathological is partly a value-laden question, this does not rule out a realist account of particular psychiatric disorders as homeostatic property cluster kinds (HPC). I assert that causal mechanisms responsible for psychiatric kinds can be understood non-metaphysically based on the contrastive-counterfactual and interventionist theories of explanation. An advantage of this account is that it can address the concern that psychiatric explanations require one to relate heterogeneous causal factors on different levels, such as genetic, neurological, psychological, and social. My novel argument is that mechanistic explanations of scientific kinds have applicability domains over which they account for specific aspects of kinds and warrant inductive inferences. That is, identifying the applicability domain of an explanation spells out the conditions under which the explanation is expected to be reliable and when it can break down. This helps to understand how different discipline approaches, including social and cultural ones, can be complementary and make an explanation of a psychiatric kind more reliable. On the other hand, the account also shows how the complex nature of psychiatric kinds can license re-classifications for different epistemic and non-epistemic purposes. Finally, in the light of the social implications of psychiatric classifications, I suggest a value-sensitive or ameliorative approach to engineering the concept of psychiatric disorder. In conclusion, my account shows that research on the social and cultural factors that shape psychiatric disorders, and weighing the non-epistemic values that influence classificatory practices, can and should inform classificatory choices as well as policy and treatment interventions.
