Psychopathology is the study of the signs and symptoms of psychiatric disorders - delusions, hallucinations, phobias, depression, for example. This book gives an account of the terms currently in use and attempts an in-depth analysis of the nature of each. The matter is examined both from a philosophical perspective and from the point of view of what is known about the function of the hemispheres of the brain.

In the formative years of psychiatry Freud, Bleuler, and Jaspers all studied Daniel Paul Schreber's Memoirs of My Nervous Illness as a model of psychotic thought. Sass provides a nuanced interpretation of Schreber's Memoirs in the context of Wittgenstein's analysis of philosophical solipsism. A dauntless critic of the illusions of philosophy, Wittgenstein likened the speculative excesses of traditional metaphysics to mental illness. Sass observes that many of the "intellectual diseases" that Wittgenstein discerned - diseases involving detachment from social existence and (...) practical concerns, and exaggerated processes of abstraction and self-consciousness - have striking affinities with the symptoms of schizophrenia. Like the philosophical solipsist, the schizophrenic may define his or her own consciousness as the center of the universe - and may experience his or her delusional world as a product of that same consciousness.

Madness and Modernism provides a phenomenological study of schizophrenic disorders, criticizing some standard conceptions of these disorders. Sass argues that many aspects of this group of disorders can actually involve more sophisticated (albeit dysfunctional) forms of mind and experience.

This chapter offers an overview of the phenomenological approach to delusions, emphasizing what Karl Jaspers called the "true delusions" of schizophrenia. Phenomenological psychopathology focuses on the experience of delusions and the delusional world. Several features of this approach are surveyed, including emphasis on formal qualities of subjective life and questioning of standard assumptions about delusions as erroneous belief. The altered modalities of world-oriented and self-oriented experience that precede and ground delusions in schizophrenia, especially the experiences of revelation that Klaus Conrad (...) termed the outer and inner apophany, are then discussed. The chapter first considers the famous "delusional mood", then the role of ipseity-disturbance. In both cases it is explained how delusions can develop out of these distinctive alterations of perception and feeling. The classic question of the understandability or comprehensibility of schizophrenic delusion, together with the related issues of wish-fulfillment and rationalizing motives are then considered. The chapter addresses the crucial but neglected issue of the felt reality-status of delusions or the delusional world, discussing derealization, "double bookkeeping", and "double exposure". The chapter concludes by discussing delusions typically found in paranoid and affective psychoses, and monothematic delusions found in certain organic conditions. (shrink)

Various forms of anomalous self-experience can be seen as central to schizophrenia and other psychiatric disorders. We examined similarities and differences between anomalous self-experiences common in schizophrenia-spectrum disorders, as listed in the EASE , and those described in published accounts of severe depersonalization. Our aims were to consider anomalous self-experience in schizophrenia in a comparative context, to refine and enlarge upon existing descriptions of experiential disturbances in depersonalization, and to explore hypotheses concerning a possible core process in schizophrenia . Numerous (...) affinities between depersonalization and schizophrenia-spectrum experience were found: these demonstrate that rather pure forms of diminished self-affection can involve many experiences that resemble those of schizophrenia. Important discrepancies also emerged, suggesting that more automatic or deficiency-like factors—probably involving self/world or self/other confusion and erosion of first-person perspective—are more distinctive of schizophrenia-spectrum disorders.

In 1910, Karl Jaspers wrote a seminal essay on morbid jealousy in which he laid the foundation for the psychopathological phenomenology that through his work and the work of Hans Gruhle and Kurt Schneider, among others, would become the ...

This entirely new translation of Critique of Pure Reason by Paul Guyer and Allan Wood is the most accurate and informative English translation ever produced of this epochal philosophical text. Though its simple, direct style will make it suitable for all new readers of Kant, the translation displays a philosophical and textual sophistication that will enlighten Kant scholars as well. This translation recreates as far as possible a text with the same interpretative nuances and richness as the original.

The concept of locally specialized functions dominates research on higher brain function and its disorders. Locally specialized functions must be complemented by processes that coordinate those functions, however, and impairment of coordinating processes may be central to some psychotic conditions. Evidence for processes that coordinate activity is provided by neurobiological and psychological studies of contextual disambiguation and dynamic grouping. Mechanisms by which this important class of cognitive functions could be achieved include those long-range connections within and between cortical regions that (...) activate synaptic channels via NMDA-receptors, and which control gain through their voltage-dependent mode of operation. An impairment of these mechanisms is central to PCP-psychosis, and the cognitive capabilities that they could provide are impaired in some forms of schizophrenia. We conclude that impaired cognitive coordination due to reduced ion flow through NMDA-channels is involved in schizophrenia, and we suggest that it may also be involved in other disorders. This perspective suggests several ways in which further research could enhance our understanding of cognitive coordination, its neural basis, and its relevance to psychopathology. Key Words: attention; cerebral cortex; cognitive coordination; cognitive neuropsychiatry; cognitive neuropsychology; context disorganization; Gamma rhythms; Gestalt theory; glutamate; grouping; memory; NMDA-receptors; PCP-psychosis; perceptual organization; schizophrenia.

There is a pattern of miscommunication bedeviling the people working on consciousness that is reminiscent of the classic Abbott and Costello 'Who's on First?' routine. With the best of intentions, people are talking past each other, seeing major disagreements when there are only terminological or tactical preferences -- or even just matters of emphasis -- that divide the sides. Since some substantive differences also lurk in this confusion, it is well worth trying to sort out. Much of the problem seems (...) to have been caused by some misdirection in my apologia for heterophenomenology , advertised as an explicitly third-person approach to human consciousness, so I will try to make amends by first removing those misleading signposts and sending us back to the real issues.

In recent years, there has been much focus on the apparent heterogeneity of schizophrenic symptoms. By contrast, this article proposes a unifying account emphasizing basic abnormalities of consciousness that underlie and also antecede a disparate assortment of signs and symptoms. Schizophrenia, we argue, is fundamentally a self-disorder or ipseity disturbance that is characterized by complementary distortions of the act of awareness: hyperreflexivity and diminished self-affection. Hyperreflexivity refers to forms of exaggerated self-consciousness in which aspects of oneself are experienced as akin (...) to external objects. Diminished self-affection or self-presence refers to a weakened sense of existing as a vital and self-coinciding source of awareness and action. This article integrates recent psychiatric research and European phenomenological psychiatry with some current work in cognitive science and phenomenological philosophy. After introducing the phenomenological approach along with a theoretical account of normal consciousness and self-awareness, we turn to a variety of schizophrenic syndromes. We examine positive, then negative, and finally disorganization symptoms—attempting in each case to illuminate shared distortions of consciousness and the sense of self. We conclude by discussing the possible relevance of this approach for identifying early schizophrenic symptoms. (shrink)

To make progress on the problem of consciousness, we have to confront it directly. In this paper, I first isolate the truly hard part of the problem, separating it from more tractable parts and giving an account of why it is so difficult to explain. I critique some recent work that uses reductive methods to address consciousness, and argue that such methods inevitably fail to come to grips with the hardest part of the problem. Once this failure is recognized, the (...) door to further progress is opened. In the second half of the paper, I argue that if we move to a new kind of nonreductive explanation, a naturalistic account of consciousness can be given. I put forward my own candidate for such an account: a nonreductive theory based on principles of structural coherence and organizational invariance, and a double-aspect theory of information.

"Our literature is replete with complaints about the chaotic state of the systematics of psychoses and every psychiatrist knows that it is impossible to come to any common understanding on the basis of the old diagnostic labels. ... Thus, not even the masters of science can make themselves understood on the basis of the old concepts and with many patients the number of diagnoses made equals the number of institutions they have been too. ... Errors are the greatest obstacles to (...) the progress of science; to correct such errors is of more practical value than to achieve new knowledge. We have here eliminated chaos of terms behind which useful concepts of disease were mistakenly sought; we have eliminated a veritable forest of boundary posts, not one of which indicated any natural line of demarcation. ... By the term „dementia praecox“ or „schizophrenia“ we designate a group of psychoses whose course is at times chronic, at times marked by intermittent attacks, and which can stop or retrograde at any stage, but does not permit a full restitutio ad integrum. The disease is characterized by a specific type of alteration of thinking, feeling, and relation to the external world which appears nowhere else in this particular fashion." Eugen Bleuler.

A pressing need for interrater reliability in the diagnosis of mental disorders emerged during the mid-twentieth century, prompted in part by the development of diverse new treatments. The Diagnostic and Statistical Manual of Mental Disorders (DSM), third edition answered this need by introducing operationalized diagnostic criteria that were field-tested for interrater reliability. Unfortunately, the focus on reliability came at a time when the scientific understanding of mental disorders was embryonic and could not yield valid disease definitions. Based on accreting problems (...) with the current DSM-fourth edition (DSM-IV) classification, it is apparent that validity will not be achieved simply by refining criteria for existing disorders or by the addition of new disorders. Yet DSM-IV diagnostic criteria dominate thinking about mental disorders in clinical practice, research, treatment development, and law. As a result, the modernDSMsystem, intended to create a shared language, also creates epistemic blinders that impede progress toward valid diagnoses. Insights that are beginning to emerge from psychology, neuroscience, and genetics suggest possible strategies for moving forward. (shrink)

Part philosophical meditation, part cultural critique, The Body in Pain is a profoundly original study that has already stirred excitement in a wide range of intellectual circles. The book is an analysis of physical suffering and its relation to the numerous vocabularies and cultural forces--literary, political, philosophical, medical, religious--that confront it.Elaine Scarry bases her study on a wide range of sources: literature and art, medical case histories, documents on torture compiled by Amnesty International, legal transcripts of personal injury trials, and (...) military and strategic writings by such figures as Clausewitz, Churchill, Liddell Hart, and Kissinger, She weaves these into her discussion with an eloquence, humanity, and insight that recall the writings of Hannah Arendt and Jean-Paul Sartre.Scarry begins with the fact of pain's inexpressibility. Not only is physical pain enormously difficult to describe in words--confronted with it, Virginia Woolf once noted, "language runs dry"--it also actively destroys language, reducing sufferers in the most extreme instances to an inarticulate state of cries and moans. Scarry analyzes the political ramifications of deliberately inflicted pain, specifically in the cases of torture and warfare, and shows how to be fictive. From these actions of "unmaking" Scarry turns finally to the actions of "making"--the examples of artistic and cultural creation that work against pain and the debased uses that are made of it. Challenging and inventive, The Body in Pain is landmark work that promises to spark widespread debate. (shrink)

Challenging and rewarding in equal measure, _Phenomenology of Perception_ is Merleau-Ponty's most famous work. Impressive in both scope and imagination, it uses the example of perception to return the body to the forefront of philosophy for the first time since Plato. Drawing on case studies such as brain-damaged patients from the First World War, Merleau-Ponty brilliantly shows how the body plays a crucial role not only in perception but in speech, sexuality and our relation to others.

Among the many peculiarities of schizophrenics perhaps the most obvious is their tendency to say odd things. Indeed, for most clinicians, the hallmark of schizophrenia is “thought disorder”. Decades of clinical observations, experimental research, and linguistic analyses have produced many hypotheses about what, precisely, is wrong with schizophrenic speech and language. These hypotheses range from assertions that schizophrenics have peculiar word association hierarchies to the notion that schizophrenics are suffering from an intermittent form of aphasia. In this article, several popular (...) hypotheses are critically assessed. Work in the area turns out to be flawed by errors in experimental method, faulty observations, tautological reasoning, and theoretical models that ignore the complexities of both speech and language. This does not mean that schizophrenics are indistinguishable from nonschizophrenics. They are clearly deviant in many situations. Their problem, however, appears to be in processing information and in selective attention, not in language itself. (shrink)

This paper offers a comparative investigation of anomalous self-experiences common in schizophrenia instrument) and those of normal individuals in an intensely introspective orientation. The latter represent a relatively pure manifestation of certain forms of exaggerated self-consciousness, one facet of the disturbance of core- or minimal-self postulated as central in schizophrenia. Significant similarities with schizophrenia-like experience were found but important differences also emerged. Affinities included feelings of passivity, fading of self or world, and alienation from thoughts, feelings, or lived-body. Differences involved (...) confusion between self and world and severe dislocation or erosion of first-person perspective, qualities unique to schizophrenia. The purpose is threefold: 1, place the putatively schizophrenic experiences of self-disorder in a broader, comparative context; 2, evaluate hypotheses concerning core processes in schizophrenia; 3, orient investigation of possible pathogenetic pathways as well as psychotherapeutic interventions.

This paper considers the nature of schizophrenic autism and urges its importance for understanding the phenomenological core of schizophrenia. Different clinical manifestations of schizophrenic autism are demonstrated, and it is asked whether these might reflect different aspects of one underlying phenomenologically intelligible phenomenon. Four phenomenological hypotheses are put forward: that autism is a function of semantic drifting, emotional drifting, ontological incompleteness, or a particular ethic rejecting common sense. By way of conclusion an integrative hypothesis is considered: that autism is intelligible (...) in terms of the experience of disembodiment. (shrink)

This chapter argues that despite the recent, welcome interest in autobiographical writing about depression, its use for research purposes presents an epistemological challenge because the extent to which these descriptions illuminate the true nature of depressive experience cannot be discerned. Contextualized within the genre of autobiography as well as the subgenre of illness memoir, the depression memoir exhibits ambiguities, it is shown, imposed by the constraints of its genre, and by the nature of autobiographical memory. Sources of ambiguity distinctive to (...) depression memoirs are next introduced, some tied to cultural meanings, others to the status of depressive states as constituted by moods. Finally, some empirical corroboration for these claims is cited, in findings indicating that depression affects autobiographical memory and writing style. The indeterminacy identified here is not a reason to dismiss depression memoirs, it is concluded, so much as to employ caution in drawing inferences from them. (shrink)

This paper offers a comparative study of abnormalities in the experience of space, time, and general atmosphere in three psychiatric conditions: schizophrenia, melancholia, and mania. It is a companion piece to our previous article entitled 'Varieties of Self- Experience'; here we focus on experiences of the world rather than of the self. As before, we are especially interested in similarities but also in some subtle distinctions in the forms of subjectivity associated with these three conditions. As before, we survey phenomenologicallyoriented (...) clinical and theoretical accounts as well as patient reports. Experiences involving forms of alienation from the practical and social world and a sense of uncanniness seem to be common in both schizophrenia and affective disorders. But despite some significant similarities, changes in schizophrenic subjectivity appear to be more pervasive and profound, involving experiences of fragmentation, meaninglessess, and ineffable strangeness that are rare or absent in the affective disorders.

This paper provides a critical survey of some subtle and often overlooked disturbances of self-experience that can occur in schizophrenia, melancholia, and mania. The goal is to better understand both similarities and differences between these conditions. We present classical and contemporary studies, mostly from the phenomenological tradition, and illustrate these with patient reports. Experiential changes in five domains of selfhood are considered: Cognition, Self-Awareness, Bodily Experiences, Demarcation/Transitivism, and Existential Reorientation. We discuss: I. major differences involving self-experience between schizophrenia and affective (...) disorders; II. experiences in which these conditions nevertheless resemble each other; III. suggestions on how these experiences may still differ on a more subtle, phenomenological plane. While affective patients may undergo significant changes in self-experience, their underlying sense of basic or minimal selfhood remains intact. In schizophrenia, basic self is disturbed, and this may help to account for many characteristic disturbances of this disorder. (shrink)

The phenomenological approach to schizophrenia has undergone something of a renaissance in Anglophone psychiatry in recent years. There has been a proliferation of works that focus on the nature of subjectivity in schizophrenia and related disorders, and that take inspiration from the work of such German and French philosophers as Husserl, Heidegger, and Merleau-Ponty, and such classical psychiatrists as Minkowski, Blankenburg, and Binswanger (Rulf 2003; Sass 2001a, 2001b). This trend includes predominantly theoretical articles, which typically incorporate clinical material as well (...) as reviews of empirical and experimental findings in psychopathology. Some very recent examples (since 2000) are studies of .. (shrink)

Much of (...) the problem seems to have been caused by some misdirection in my apologia for heterophenomenology, advertised as an explicitly third - person approach to human consciousness, so I will try to make amends by first removing those misleading signposts and sending us back to the real issues. On the face of it, the study of human consciousness involves phenomena that seem to occupy something rather like another dimension : the private, subjective, ‘ first - person ’ dimension. Everybody agrees that this is where we start. What, then, is the relation between the standard ‘ third - person ’ objective methodologies for studying meteors or magnets, and the methodologies for studying human consciousness? Can the standard methods be extended in such a way as to do justice to the phenomena of human consciousness? Or do we have to find some quite radical or revolutionary alternative science? I have defended the hypothesis that there is a straightforward, conservative extension of objective science that handsomely covers the ground — all the ground — of human consciousness, doing justice to all the data without ever having to abandon the rules and constraints of the experimental method that have worked so well in the rest of science. This third - person methodology, dubbed heterophenomenology, is, I have claimed, the sound way to take the first person point of view as seriously as it can be taken. (shrink)
