In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all further (...) questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined. (shrink)

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role (...) of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM – whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part 1 of this article took up the first two questions. Part 2 took up the second two questions. Part 3 now deals with Questions 5 & 6. Question 5 confronts the issue of utility, whether the manual design of DSM-III and IV favors clinicians or researchers, and what that means for DSM-5. Our final question, Question 6, takes up a concluding issue, whether the acknowledged problems with the earlier DSMs warrants a significant overhaul of DSM-5 and future manuals. As in Parts 1 & 2 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role (...) of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM - whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article will take up the first two questions. With the first question, invited commentators express a range of opinion regarding the nature of psychiatric disorders, loosely divided into a realist position that the diagnostic categories represent real diseases that we can accurately name and know with our perceptual abilities, a middle, nominalist position that psychiatric disorders do exist in the real world but that our diagnostic categories are constructs that may or may not accurately represent the disorders out there, and finally a purely constructivist position that the diagnostic categories are simply constructs with no evidence of psychiatric disorders in the real world. The second question again offers a range of opinion as to how we should define a mental or psychiatric disorder, including the possibility that we should not try to formulate a definition. The general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

Part I of this article took up the first two questions. Part II will take up the second two questions. Question 3 deals with the question as to whether DSM-V should assume a conservative or assertive posture in making changes from DSM-IV. That question in turn breaks down into discussion of diagnoses that depend on, and aim toward, empirical, scientific validation, and diagnoses that are more value-laden and less amenable to scientific validation. Question 4 takes up the role of pragmatic consideration in a psychiatric nosology, whether the purely empirical considerations need to be tempered by considerations of practical consequence. As in Part 1 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.

In its central use “phenomenology” names a movement in twentieth century philosophy. A second use of “phenomenology” common in contemporary philosophy names a property of some mental states, the property they have if and only if there is something it is like to be in them. Thus, it is sometimes said that emotional states have a phenomenology while belief states do not. For example, while there is something it is like to be angry, there is nothing it is like to (...) believe that Paris is in France. Although the two uses of “phenomenology” are related, it is the first which is the current topic. Accordingly, “phenomenological” refers to a way of doing philosophy that is more or less closely related to the corresponding movement. Phenomenology utilizes a distinctive method to study the structural features of experience and of things as experienced. It is primarily a descriptive discipline and is undertaken in a way that is largely independent of scientific, including causal, explanations and accounts of the nature of experience. Topics discussed within the phenomenological tradition include the nature of intentionality, perception, time-consciousness, self-consciousness, awareness of the body and consciousness of others. Phenomenology is to be distinguished from phenomenalism, a position in epistemology which implies that all statements about physical objects are synonymous with statements about persons having certain sensations or sense-data. George Berkeley was a phenomenalist but not a phenomenologist. -/- Although elements of the twentieth century phenomenological movement can be found in earlier philosophers—such as David Hume, Immanuel Kant and Franz Brentano—phenomenology as a philosophical movement really began with the work of Edmund Husserl. Following Husserl, phenomenology was adapted, broadened and extended by, amongst others, Martin Heidegger, Jean-Paul Sartre, Maurice Merleau-Ponty, Emmanuel Levinas and Jacques Derrida. Phenomenology has, at one time or another, been aligned with Kantian and post-Kantian transcendental philosophy, existentialism and the philosophy of mind and psychology. -/- This article introduces some of the central aspects of the phenomenological method and also concrete phenomenological analyses of some of the topics that have greatly exercised phenomenologists.

An increasing number of scholars at the intersection of feminist philosophy and critical disability studies have turned to Merleau-Ponty to develop phenomenologies of disability or of what, following Rosemarie Garland-Thomson, I call "non-normate" embodiment. These studies buck the historical trend of philosophers employing disability as an example of deficiency or harm, a mere litmus test for normative theories, or an umbrella term for aphenotypical bodily variation. While a Merleau-Pontian-inspired phenomenology is a promising starting point for thinking about embodied experiences of (...) all sorts, I here draw a cautionary tale about how ableist assumptions can easily undermine accounts of non-normate experience. I first argue that the omission or misguided treatment of disability within the history of philosophy in general and the phenomenological tradition in particular is due to the inheritance of what I call “the ableist conflation” of disability with pain, suffering, and disadvantage. I then show that Merleau-Ponty’s famous reading of the blind man’s cane is problematic insofar as it omits the social dimensions of disabled experiences, misconstrues the radicality of blindness as a world-creating disability, and operates via an able-bodied simulation that confuses object annexation or extension with incorporation. In closing, I contend that if phenomenology is to overcome the errors of traditional philosophy, as Merleau-Ponty once hoped, it must heed the insights of “crip” or non-normate phenomenology, which takes the lived experience of disability as its point of departure.

Some recent developments in Artificial Intelligence—especially the use of machine learning systems, trained on big data sets and deployed in socially significant and ethically weighty contexts—have led to a number of calls for “transparency”. This paper explores the epistemological and ethical dimensions of that concept, as well as surveying and taxonomising the variety of ways in which it has been invoked in recent discussions. Whilst “outward” forms of transparency may be straightforwardly achieved, what I call “functional” transparency about the inner (...) workings of a system is, in many cases, much harder to attain. In those situations, I argue that contestability may be a possible, acceptable, and useful alternative so that even if we cannot understand how a system came up with a particular output, we at least have the means to challenge it.

In this paper, I outline two strands of evidence for the conclusion that the dynamical approach to cognitive science both seeks and provides covering law explanations. Two of the most successful dynamical models—Kelso’s model of rhythmic finger movement and Thelen et al.’s model of infant perseverative reaching—can be seen to provide explanations which conform to the famous explanatory scheme first put forward by Hempel and Oppenheim. In addition, many prominent advocates of the dynamical approach also express the provision of this (...) kind of explanation as a goal of dynamical cognitive science. I conclude by briefly outlining two consequences. First, dynamical cognitive science’s explanatory style may strengthen its links to the so-called “situated” approach to cognition, but, secondly, it may also undermine the widespread intuition that dynamics is related to emergentism in the philosophy of mind.

In an attempt to bridge the vast divide between classical Asian thought and contemporary Western philosophy, Joel J. Kupperman finds that the two traditions do not, by and large, supply different answers to the same questions. Rather, each tradition is searching for answers to their own set of questions--mapping out distinct philosophical investigations. In this groundbreaking book, Kupperman argues that the foundational Indian and Chinese texts include lines of thought that can enrich current philosophical practice, and in some cases (...) provide uniquely sophisticated insights. Special attention is given to the ethical issues of formation and fluidity of self, the nature and possibilities of choice, the compartmentalization of life implicit in some ethical systems, the variations of ethical demands from person to person, and the nature of philosophy itself as a communicative activity. This study will provide a wealth of information for philosophers seeking a closer knowledge of Asian philosophy and general readers with an interest in Eastern thought. (shrink)

There is growing philosophical interest in “affective injustice”: injustice faced by individuals specifically in their capacity as affective beings. Current debates tend to focus on affective injustice at the psychological level. In this paper, I argue that the built environment can be a vehicle for affective injustice — specifically, what Wildman et al. (2022) term “affective powerlessness”. I use resources from ecological psychology to develop this claim. I consider two cases where certain kinds of bodies are, either intentionally or unintentionally, (...) deprived of access to goods affording the development and maintenance of their subjective well-being: hostile architecture and masking practices in autism. This deprivation, I argue further, leads to a significant weakening and diminishment of their spatial agency, hinders their well-being, and in so doing gives rise to a pervasive experience of affective powerlessness. By drawing attention to these themes, I show that an ecological approach helpfully supplements existing approaches. It highlights how affective injustice can emerge via the way bodies are positioned in space, and the central role that built environments play in determining this positioning. (shrink)

In this article, we describe a hitherto undocumented fallacy-in the sense of a mistake in reasoning-constituted by a negativity bias in the way that people attribute motives to others. We call this the "worst-motive fallacy," and we conducted two experiments to investigate it. In Experiment 1, participants expected protagonists in a variety of fictional vignettes to pursue courses of action that satisfy the protagonists' worst motive, and furthermore, participants significantly expected the protagonist to pursue a worse course of action than (...) they would prefer themselves. Experiment 2 was a preregistered attempted replication of Experiment 1, including a bigger range of vignettes; the first effect was not replicated for the new vignettes tested but was for the original set. Also, we once again found that participants expected protagonists to be more likely than they were themselves to pursue courses of action that they considered morally bad. We discuss the worst-motive fallacy's relation to other well-known biases as well as its possible evolutionary origins and its ethical consequences. (shrink)

This book traces how such a seemingly immutable idea as measurement proved so malleable when it collided with the subject matter of psychology. It locates philosophical and social influences reshaping the concept and, at the core of this reshaping, identifies a fundamental problem: the issue of whether psychological attributes really are quantitative. It argues that the idea of measurement now endorsed within psychology actually subverts attempts to establish a genuinely quantitative science and it urges a new direction. It relates views (...) on measurement by thinkers such as Holder, Russell, Campbell and Nagel to earlier views, like those of Euclid and Oresme. Within the history of psychology, it considers contributions by Fechner, Cattell, Thorndike, Stevens and Suppes, among others. It also contains a non-technical exposition of conjoint measurement theory and recent foundational work by leading measurement theorist R. Duncan Luce. (shrink)

This paper examines the widespread intuition that the dynamical approach to cognitive science is importantly related to emergentism about the mind. The explanatory practices adopted by dynamical cognitive science rule out some conceptions of emergence; covering law explanations require a deducibility relationship between explanans and explanandum, whereas canonical theories of emergence require the absence of such deducibility. A response to this problem – one which would save the intuition that dynamics and emergence are related – is to reconstrue the concept (...) of emergence as a relationship between laws. I call this “nomological emergence” and comment on the extent to which dynamicists would find it acceptable. Alternatively, dynamical cognitive science might be viewed as fitting better with the kind of “functional reductionism” which has recently been developed by authors such as Jaegwon Kim. Which of these two alternatives is preferable remains an open question pending the further development of dynamical cognitive science, particularly in its “non-classical” forms. (shrink)

In this paper, I argue that the account of emergence advanced by Broad is both defensible and applicable to some examples of group-level phenomena. Specifically, Broad’s account enables the formulation of a non-reductive physicalism or of a non-reductive individualism, and correctly describes the case of group-judgment under the conditions of the discursive dilemma. Furthermore, this analysis shows that emergent phenomena need not be characterised using the resources of complexity theory.

This first volume in the four-volume series The Moral Limits of the Criminal Law focuses on the "harm principle," the commonsense view that prevention of harm to persons other than the perpetrator is a legitimate purpose of criminal legislation. Feinberg presents a detailed analysis of the concept and definition of harm and applies it to a host of practical and theoretical issues, showing how the harm principle must be interpreted if it is to be a plausible guide to the lawmaker.

One of liberalism’s core commitments is to safeguarding individuals’ autonomy. And a central aspect of liberal social justice is the commitment to protecting the vulnerable. Taken together, and combined with an understanding of autonomy as an acquired set of capacities to lead one’s own life, these commitments suggest that liberal societies should be especially concerned to address vulnerabilities of individuals regarding the development and maintenance of their autonomy. In this chapter, we develop an account of what it would mean for (...) a society to take seriously the obligation to reduce individuals’ autonomy-related vulnerabilities to an acceptable minimum. In particular, we argue that standard liberal accounts underestimate the scope of this obligation because they fail to appreciate various threats to autonomy. (shrink)

The two contrasting theoretical approaches to visual perception, the constructivist and the ecological, are briefly presented and illustrated through their analyses of space and size perception. Earlier calls for their reconciliation and unification are reviewed. Neurophysiological, neuropsychological, and psychophysical evidence for the existence of two quite distinct visual systems, the ventral and the dorsal, is presented. These two perceptual systems differ in their functions; the ventral system's central function is that of identification, while the dorsal system is mainly engaged in (...) the visual control of motor behavior. The strong parallels between the ecological approach and the functioning of the dorsal system, and between the constructivist approach and the functioning of the ventral system are noted. It is also shown that the experimental paradigms used by the proponents of these two approaches match the functions of the respective visual systems. A dual-process approach to visual perception emerges from this analysis, with the ecological-dorsal process transpiring mainly without conscious awareness, while the constructivist-ventral process is normally conscious. Some implications of this dual-process approach to visual-perceptual phenomena are presented, with emphasis on space perception. Key Words: constructivist; dual-process approach; ecological; size perception; space perception; two visual systems; visual perception theories. (shrink)

This paper introduces the philosophy of Grace Andrus de Laguna in order to renew interest in it. I show that, in the 1910s and 1920s, she develops ideas and arguments that are also found playing key roles in the development of analytic philosophy decades later. Further, I describe her sympathetic, but acute, criticism of pragmatism and Heideggerian ontology, and situate her work in the tradition of American, speculative philosophy. Before 1920, we will see, de Laguna appeals to multiple realizability to (...) undermine reductionism in science, to support perspectival, scientific realism and, with help from a private language argument, to favour the view that mental states are classified by behavioural, teleological roles over what came to be called ‘type physicalism’. Her view of speech, mostly developed in the 1920s, tells us that its primary role is coordinating group behaviour rather than expressing thoughts. Belief is understood in terms of its causal role, including its causal relations to other kinds of mental states, when coordinating group behaviour. Thought is similarly understood. In developing her theory of mind, de Laguna rejects the pragmatist claims that belief can be reduced to dispositions to behaviour and that thought’s function is to address specific, rather than general, problems. She also favours meaning holism and rejects the analytic–synthetic distinction. In later work, de Laguna argues that individuals’ activity of self-maintenance brings universals, conceived of as irreducible potentialities, into being and makes them increasingly determinate. Further, she identifies the existence of all individuals with forms of self-maintenance and takes the existence of people to include maintenance of the cultural world. Such a unified treatment of existence, she holds, permits making its evolution intelligible. Heidegger’s view of being is rejected for not permitting this. All de Laguna’s work, we will see, fits a vision of philosophy as the systematic, imaginative and naturalistic examination of being as well as a source of criticism of science. (shrink)
