Why do some invertebrates store so much carotenoids in their tissues? Storage of carotenoids may not simply be passive and dependent on their environmental availability, as storage variation exists at various taxonomic scales, including among individuals within species. While the strong antioxidant and sometimes immune-stimulating properties of carotenoids may be beneficial enough to cause the evolution of features improving their assimilation and storage, they may also have fitness downsides explaining why massive carotenoid storage is not universal. Here, the functional and (...) ecological implications of carotenoid storage for the evolution of invertebrate innate immune defenses are examined, especially in crustaceans, which massively store carotenoids for unclear reasons. Three testable hypotheses about the role of carotenoid storage in immunological (resistance and tolerance) and life-history strategies (with a focus on aging) are proposed, which may ultimately explain the storage of large amounts of these pigments in a context of host–pathogen interactions.

Cancers rely on multiple, heterogeneous processes at different scales, pertaining to many biomedical fields. Therefore, understanding cancer is necessarily an interdisciplinary task that requires placing specialised experimental and clinical research into a broader conceptual, theoretical, and methodological framework. Without such a framework, oncology will collect piecemeal results, with scant dialogue between the different scientific communities studying cancer. We argue that one important way forward in service of a more successful dialogue is through greater integration of applied sciences (experimental and clinical) (...) with conceptual and theoretical approaches, informed by philosophical methods. By way of illustration, we explore six central themes: (i) the role of mutations in cancer; (ii) the clonal evolution of cancer cells; (iii) the relationship between cancer and multicellularity; (iv) the tumour microenvironment; (v) the immune system; and (vi) stem cells. In each case, we examine open questions in the scientific literature through a philosophical methodology and show the benefit of such a synergy for the scientific and medical understanding of cancer.

Christopher Boorse’s biostatistical theory of medical disorder claims that biological part-dysfunction (i.e., failure of an internal mechanism to perform its biological function), a factual criterion, is both necessary and sufficient for disorder. Jerome Wakefield’s harmful dysfunction analysis of medical disorder agrees that part-dysfunction is necessary but rejects the sufficiency claim, maintaining that disorder also requires that the part-dysfunction causes harm to the individual, a value criterion. In this paper, I present two considerations against the sufficiency claim. First, I analyze Boorse’s (...) central argument for the sufficiency claim, the “pathologist argument,” which takes pathologists’ intuitions about pathology as determinative of medical disorder and conclude that it begs the question and fails to support the sufficiency claim. Second, I present four counterexamples from the medical literature in which salient part-dysfunctions are considered nondisorders, including healthy disease carriers, HIV-positive status, benign mutations, and situs inversus totalis, thus falsifying the sufficiency claim and supporting the harm criterion.

In examining the puzzle of experience, and its possible solutions, Valberg discusses relevant views of Hume, Kant, Heidegger, Wittgenstein, and Strawson, as well as ideas from the recent philosophy of perception. Finally, he describes and analyzes a manifestation of the puzzle outside philosophy, in everyday experience.

Wakefield’s harmful dysfunction analysis asserts that the concept of medical disorder includes a naturalistic component of dysfunction and a value component, both of which are required for disorder attributions. Muckler and Taylor, defending a purely naturalist, value-free understanding of disorder, argue that harm is not necessary for disorder. They provide three examples of dysfunctions that, they claim, are considered disorders but are entirely harmless: mild mononucleosis, cowpox that prevents smallpox, and minor perceptual deficits. They also reject the proposal that dysfunctions (...) need only be typically harmful to qualify as disorders. We argue that the proposed counterexamples are, in fact, considered harmful; thus, they fail to disconfirm the harm requirement: incapacity for exertion is inherently harmful, whether or not exertion occurs, cowpox is directly harmful irrespective of indirect benefits, and colorblindness and anosmia are considered harmful by those who consider them disorders. We also defend the typicality qualifier as viably addressing some apparently harmless disorders and argue that a dysfunction’s harmfulness is best understood in dispositional terms. (shrink)

In ‘Rethinking Disease’, Powell and Scarffe1 propose what in effect is a modification of Jerome Wakefield’s2 3 harmful dysfunction analysis of medical disorder. The HDA maintains that ‘disorder’ is a hybrid factual and value concept requiring that a biological dysfunction, understood as a failure of some feature to perform a naturally selected function, causes harm to the individual as evaluated by social values. Powell and Scarffe accept both the HDA’s evolutionary biological function component and its incorporation of a value component. (...) Their proposed ‘new twist’ is to revise the value component: ‘Our proposed definition of disease is as follows: a biomedical state is a disease only if it implicates a biological dysfunction that is, or would be, properly disvalued’. So, they propose that a disorder is a ‘properly disvalued dysfunction’ rather than a ‘harmful dysfunction’, an approach they term ‘thickly normative’ in contrast to the thin normative approach of the HDA. There has been a surge of interest recently in better understanding the ‘harm’ component of the HDA. Powell and Scarffe’s analysis is a helpful contribution to this discussion. We focus here exclusively on their proposal regarding the analysis of the concept of disorder and ignore many important related issues that the authors address, ranging from prioritising resource allocation between disorders and non-disorders to whether the concept of disorder should be replaced by a generic welfarist concept. The resolution of these additional issues depends on first understanding ‘disorder’. The authors’ proposed changes to the HDA also deserve evaluation because the HDA, which has been endorsed by leading nosologists,4 plays an influential role in nosological debate across categories of disorder ranging, for example, from sexual paraphilias5 to psychopathy.6 A basic problem is that Powell and Scarffe misinterpret ….

We propose that learning has a top-down component, but not in the propositional terms described by Mitchell et al. Specifically, we propose that a host of learning processes, including associative learning, serve to imbue the representation of the conditioned stimulus (CS) with affective meaning.

Three experiments explored the effects of word problem cueing on debiasing versions of the bat-and-ball problem. In the experimental condition order, participants solved a simpler isomorphic version of the problem prior to solving a standard version that, critically, had the same item-and-dollar amounts. Conversely, in the control condition order, participants solved the standard version prior to solving the isomorph. Across the first 2 experiments, participants cued with the isomorph were more likely to correctly solve the standard version of the problem. (...) In the third experiment, this cueing effect was not replicated, but importantly cued participants were more likely to correctly solve the standard version of the problem with other item-and-dollar amounts, indicating near transfer. Far transfer was evident in faster response times to other problems in the Cognitive Reflection Test following practice. Along with providing converging evidence for the cueing account, these results are consistent with recent attentional debiasing findings. (shrink)

Much of our understanding of human thinking is based on probabilistic models. This innovative book by Jerome R. Busemeyer and Peter D. Bruza argues that, actually, the underlying mathematical structures from quantum theory provide a much better account of human thinking than traditional models. They introduce the foundations for modelling probabilistic-dynamic systems using two aspects of quantum theory. The first, 'contextuality', is a way to understand interference effects found with inferences and decisions under conditions of uncertainty. The second, 'quantum entanglement', (...) allows cognitive phenomena to be modeled in non-reductionist ways. Employing these principles drawn from quantum theory allows us to view human cognition and decision in a totally new light. Introducing the basic principles in an easy-to-follow way, this book does not assume a physics background or a quantum brain and comes complete with a tutorial and fully worked-out applications in important areas of cognition and decision.

This, the third edition of Fundamentals of Experimental Design, has five added chapters - those on regression (Chapters 12, 14, and 15), multivariate analysis (Chapter 18), and the matrix algebra appropriate to the level of presentation of this material (Chapter 13). I have noted in the preface other additions in this third edition. The added material should enhance the value of the book as a textbook and a reference. Given these additions, however, alternative approaches in using the current edition as (...) a textbook may merit consideration. It may help to note that Chapters 16 and 17 (analysis of covariance, trend analysis) do not depend on the material in Chapters 12 through 15, although the student should know something about simple linear regression to be able to understand fully the material in Chapters 16 and 17. In any event, the instructor who wants to teach only the material in the first two editions can do so by dropping the added chapters - 12 through 15, and 18 - from the syllabus. (shrink)

This paper presents a general computational treatment of how mammals are able to deal with visual objects and environments. The model tries to cover the entire range from behavior and phenomenological experience to detailed neural encodings in crude but computationally plausible reductive steps. The problems addressed include perceptual constancies, eye movements and the stable visual world, object descriptions, perceptual generalizations, and the representation of extrapersonal space.The entire development is based on an action-oriented notion of perception. The observer is assumed to (...) be continuously sampling the ambient light for information of current value. The central problem of vision is taken to be categorizing and locating objects in the environment. The critical step in this process is the linking of visual information to symbolic object descriptions; this is calledindexing, from the analogy of identifying a book from index terms. The system must also identifysituationsand use this knowledge to guide movement and other actions in the environment. The treatment focuses on the different representations of information used in the visual system.The four representational frames capture information in the following forms: retinotopic, head-based, symbolic, and allocentric. The functional roles of the four frames, the communication among them, and their suggested neurophysiological realization constitute the core of the paper. The model is perforce crude, but appears to be consistent with all relevant findings. (shrink)

First published in 1977, Emotion, Thought and Therapy is a study of Hume and Spinoza and the relationship of philosophical theories of the emotions to psychological theories of therapy. Jerome Neu argues that the Spinozists are closer to the truth; that is, that thoughts are of greater importance than feelings in the classification and discrimination of emotional states. He then contends that if the Spinozists are closer to the truth, we have the beginning of an argument to show that Freudian (...) or analytic therapies make philosophic sense. Throughout the book, careful attention is paid to modern discussions in philosophy of mind and psychology, and materials from anthropology and other relevant disciplines are considered. At the centre of the discussion is the notion of ‘thought-dependence’. Therapies for psychological disorders are placed along a spectrum in accordance with the role they assign to thoughts. The Spinozist view of the emotions can be seen as at the extreme thought end of a corresponding spectrum of theories of the emotions. The book suggests that this stream may help explain the spectrum of therapeutic theories and the possibilities that exist for psychological development and change. This book will be of interest to students of philosophy, psychology and counselling. (shrink)

In this two-part analysis, I analyze Marc Lewis’s arguments against the brain-disease view of substance addiction and for a developmental-learning approach that demedicalizes addiction. I focus especially on the question of whether addiction is a medical disorder. In Part 1, I argued that, even if one accepts Lewis’s critique of the brain evidence presented for the brain-disease view, his arguments fail to establish that addiction is not a disorder. Relying on my harmful dysfunction analysis of disorder, I defended the view (...) that addiction is a medical disorder and a brain disorder. In Part 2, I consider some broader philosophical issues raised by Lewis’s arguments: I consider a larger puzzle, at the heart of the neo-Kraepelinian program in contemporary psychiatry, that is raised by Lewis’s argument that addiction is not a disorder because the brain displays no damage but only normal learning: must all mental disorders be brain disorders, or can mental disorders occur in normal brains? I argue that mental disorders can occur in normal brains. I critique Lewis’s response to the evolutionary “novel environment” approach to explaining why addiction is a disorder. Lewis agrees with brain-disease proponents that interpreting addiction as brain disorder relieves addicts of moral censure, but I argue that moral defect and brain disease are not exclusive. Finally, I consider Lewis’s “developmental-learning” account of addiction that encourages positive and empowering narrativizing of addiction, but I argue that the developmental-learning view is vacuous due to use of an overly broad notion of “development.”.

This essay argues that Plato’s Republic includes a widely overlooked meditation on the affective dimension of political judgment. This meditation occurs in the passages on music. In music, Plato identifies the possibility of an extra-rational aesthetic activity that prepares the soul for reasoned judgment: he makes musical mimesis the precondition to logos because of its ability to actualize in the soul the very ethos required of sound judgment. Music is able to do this because it is not imagistic; music does (...) not produce mediated representations but rather produces alterations in the condition of the soul itself. These alterations are made possible because the soul itself is structured musically. If music actualizes the conditions of the soul, so too does the soul instantiate the conditions of music. In his treatment of musical mimesis, Plato thereby makes disposition, or affect, the defining feature of sound judgment. (shrink)

In the first part of this article, I argue that Christopher Megone's natural-kind interpretation of Aristotle's argument that "the function of a human being is reason" does not resolve major puzzles about the argument, specifically the puzzles of why a human being has a function and why reason is that function. I attempt to resolve these puzzles by supplementing the natural-kind account with the doctrine that reason is the master regulatory natural function by which individuals enter into social life. In (...) the second half, I critique Megone's value account of function and argue for a nonevaluative, causal-explanatory account of function and teleological explanation. (shrink)

This remarkable book is the most comprehensive study ever written of the history of moral philosophy in the seventeenth and eighteenth centuries. Its aim is to set Kant's still influential ethics in its historical context by showing in detail what the central questions in moral philosophy were for him and how he arrived at his own distinctive ethical views. The book is organised into four main sections, each exploring moral philosophy by discussing the work of many influential philosophers of the (...) seventeenth and eighteenth centuries. In an epilogue the author discusses Kant's view of his own historicity, and of the aims of moral philosophy. In its range, in its analyses of many philosophers not discussed elsewhere, and in revealing the subtle interweaving of religious and political thought with moral philosophy, this is an unprecedented account of the evolution of Kant's ethics.

The harmful dysfunction (HD) analysis of "disorder" holds that disorders are harmful failures of "designed" (that is, naturally selected) functions. Murphy and Woolfolk (2000) present a series of proposed counterexamples to the HD analysis to support their claim that it fails to provide a necessary condition for disorder. They argue that disorder can exist where there is no failed function, as in failed spandrels and inflamed vestigial organs, and that there can be disorders when everything is working as designed, as (...) in environment--design mismatches and disorders acquired through normal learning processes. They also argue that the HD analysis suffers from methodological problems, including value-ladenness of dysfunction judgments and unwarranted assumptions about the nature of internal mechanisms and their functions. -/- In this paper, each of these objections is critically evaluated. Reanalysis of the proposed counterexamples is argued to reveal strong support for the HD analysis. For example, failed spandrels are considered disorders when and only when they imply failures of designed functions; dysfunctions of vestigial organs involve failures of function at the tissue level, not the organ level; mechanism-environment mismatches are not considered disorders; and conditions acquired through normal learning processes can involve dysfunctions and are considered disordered only when they do. Murphy and Woolfolk's methodological objections are found to be based on a misinterpretation of the HD analysis. It is concluded that Murphy and Woolfolk fail to offer a cogent objection to the HD analysis. (shrink)

In this two-part analysis, I analyze Marc Lewis’s arguments against the brain-disease view of substance addiction and for a developmental-learning approach that demedicalizes addiction. I focus especially on the question of whether addiction is a medical disorder. Addiction is currently classified as a medical disorder in DSM-5 and ICD-10. It is further labeled a brain disease by NIDA, based on observed brain changes in addicts that are interpreted as brain damage. Lewis argues that the changes result instead from normal neuroplasticity (...) and learning in response to the intense rewards provided by addictive substances, thus that addiction is not a brain disease and by implication not a medical disorder at all. I argue that even if one accepts Lewis’s reinterpretation of the brain evidence, his conclusions do not follow. Relying on my harmful-dysfunction analysis of medical disorder, I defend the view that substance addiction is in fact a medical disorder and a brain disorder. In Part 1, I identify five arguments Lewis puts forward against the brain-disease view and evaluate them as arguments that addiction is not a disorder: Addiction is not a chronic, relapsing condition; There is no clear boundary between addiction and other strong desires; Negative consequences are not unique to disorders; The brain disease model does not account for behavioral addictions; and, Addiction is like love. I argue that Lewis’s arguments are invalid because they fail to take account of the context of addiction and its relation to biological design. (shrink)

Pierre-Henri Castel provides a short but richly argued precis of his recently published two-volume 1,000-page masterwork on the history of obsessive-compulsive disorder. Having not read the as-yet-untranslated books, I write this commentary from Plato’s cave, trying to infer the reality of Castel’s analysis from expository shadows. I am unlikely to be more successful than Plato’s poor troglodytes, so I apologize ahead of time for any misunderstandings. Moreover, I cannot assess Castel’s detailed evidential case for his substantive theses.1 I thus focus (...) on some key philosophical issues that impinge on an area of my concern, the concept of mental disorder. Castel is a rare breed of French.. (shrink)

Episodic memory involves the sense that it is “first-hand”, i.e., originates directly from one’s own past experience. An account of this phenomenological dimension is offered in terms of an affective experience or feeling specific to episodic memory. On the basis of recent empirical research in the domain of metamemory, it is claimed that a recollective experience involves two separate mental components: a first-order memory about the past along with a metacognitive, episodic feeling of knowing. The proposed two-tiered account is contrasted (...) with other, reductionist two-tiered accounts as well as with reflexive accounts of episodic memory to be found in the literature. (shrink)

This book consists of a focused and systematic analysis of Freud’s implicit argument for unconscious mental states. The author employs the unique approach of applying contemporary philosophical methods, especially Kripke-Putnam essentialism, in analyzing Freud’s argument.

Indeed, Freud redirected Brentano's analysis of consciousness as intentionality into a view of consciousness-independent intentionalism about the mental that in (...) effect set the agenda for latter-twentieth-century philosophy of mind.

A popular idea at present is that emotions are perceptions of values. Most defenders of this idea have interpreted it as the perceptual thesis that emotions present (rather than merely represent) evaluative states of affairs in the way sensory experiences present us with sensible aspects of the world. We argue against the perceptual thesis. We show that the phenomenology of emotions is compatible with the fact that the evaluative aspect of apparent emotional contents has been incorporated from outside. We then (...) deal with the only two views that can make sense of the perceptual thesis. On the response–dependence view, emotional experiences present evaluative responsedependent properties (being fearsome, being disgusting, etc.) in the way visual experiences present response-dependent properties such as colors. On the response–independence view, emotional experiences present evaluative response-independent properties (being dangerous, being indigestible, etc.), conceived as ‘Gestalten’ independent of emotional feelings themselves. We show that neither view can make plausible the idea that emotions present values as such, i.e., in an open and transparent way. If emotions have apparent evaluative contents, this is in fact due to evaluative enrichments of the non-evaluative presentational contents of emotions. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:What Makes a Mental Disorder Mental?Jerome C. Wakefield (bio)Keywordsharmful dysfunction, mental disorder, intentionality, mental dysfunction, mental functioning, phenomenality, somatic disorderWhat makes a medical disorder mental rather than (exclusively) somatic or physical? Psychiatry to some extent depends for its existence as a medical specialty on the distinction between mental and somatic disorders, yet the history of this distinction presents a bewildering array of puzzling judgments, radical shifts, and seemingly arbitrary (...) distinctions. The historical observation that putative mental disorders are often reclassified as physical disorders as soon as their physiologic basis is understood further confuses matters. Moreover, recent debates about such classifications often seem to reflect desires to protect professional turf or obtain optimal reimbursement for treatment more than they do the application of a coherent conceptual distinction. No wonder that Brülde and Radovic (2006) disarmingly admit at the outset of their exploration of this question that there is a case to be made that their topic is relatively unimportant or even meaningless intellectually, a rare way to start an inquiry!Could there nonetheless be a cogent conceptual distinction lurking here? Brülde and Radovic usefully invite us to reframe the question, in effect as follows: Suppose we pay attention to professional and lay judgments as evidence but at the same time try to avoid being ensnared by the distortions resulting from turf issues and other pragmatic motives and constraints. Can we then identify some principled distinction in this domain that is worth making and that interestingly corresponds to the distinction generally made between mental disorders and strictly somatic disorders? Brülde and Radovic do not come to any confident or compelling conclusion about this.My answer, based on my harmful dysfunction analysis of disorder (Wakefield, 1992a, 1992b, 1999a, 1999b), is that a mental disorder is a harmful mental dysfunction, where a mental dysfunction is a failure of the capacity of some mental mechanism to perform a function for which it was biologically designed. I argue that, owing to a series of logical missteps, Brülde and Radovic needlessly reject this view. After some preliminary comments and clarifications, I defend the internal dysfunction approach from the objections posed by Brülde and Radovic, and then conclude by elaborating this view in some new ways. Note that Brülde and Radovic critique something they call the "internal cause view" of what makes a disorder mental, and they name others who hold that view. However, my work figures prominently in their discussion, and for expository simplicity, I will presume to simply construe their arguments as aimed at the harmful dysfunction analysis. [End Page 123]Clarifying the QuestionIt is easy to misconstrue the question "What makes a mental disorder mental" as demanding a precise account of the mental, an error to which Brülde and Radovic succumb in their repeated complaints that various writers do not present principled accounts of the mental but rely on lists of prototypical mental states or tentative guidelines to fix the reference of mental. We would need a precise definition of mental if the problem were how to classify cases in which it is ambiguous whether some phenomenon is mental or physical. We might imagine, for example, someone being genuinely puzzled as to whether inability to sleep is failure of a mental function or process. But this sort of puzzle about the boundaries of the mental is not the problem with which Brülde and Radovic are concerned; anyway, ambiguous cases may just be inherently ambiguous. The problem, which a crisp definition of mental will not resolve, is what relation mental states or mechanisms must have to a disorder to make it a mental disorder; must there be mental symptoms, or mental dysfunctions, or either one, and so on? But, even if a precise resolution of the nature of the mental is not needed, some notion of the mental domain is essential in pursuing this discussion. We can pick out the mental ostensively, by pointing to lots of examples (e.g., perception, motivation, emotion, thought, and sensation) much more confidently than we can define it in a principled way. But because Brülde and Radovic find fault in such ostensive reference fixing, let me... (shrink)
