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 ...

Delusional beliefs have sometimes been considered as rational inferences from abnormal experiences. We explore this idea in more detail, making the following points. Firstly, the abnormalities of cognition which initially prompt the entertaining of a delusional belief are not always conscious and since we prefer to restrict the term “experience” to consciousness we refer to “abnormal data” rather than “abnormal experience”. Secondly, we argue that in relation to many delusions (we consider eight) one can clearly identify what the abnormal cognitive (...) data are which prompted the delusion and what the neuropsychological impairment is which is responsible for the occurrence of these data; but one can equally clearly point to cases where this impairments is present but delusion is not. So the impairment is not sufficient for delusion to occur. A second cognitive impairment, one which impairs the ability to evaluate beliefs, must also be present. Thirdly (and this is the main thrust of our chapter) we consider in detail what the nature of the inference is that leads from the abnormal data to the belief. This is not deductive inference and it is not inference by enumerative induction; it is abductive inference. We offer a Bayesian account of abductive inference and apply it to the explanation of delusional belief. (shrink)

The result is nothing less than a fundamental reorientation of moral theory that enables it at last to account for morality's supreme authority--an account that ...

Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one's own mind? (...) Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry. This article will provide a systematic overview of the problems that the questions above raise and focus in some depth on issues relating to the structure and the limits of knowledge and justification.

Many psychiatrists tell their clients that any mental disorder is ‘‘a disease, just like diabetes’’. This slogan appears to suggest that mental states and behavior that are classified ‘‘mental disorders’’ are somehow radically different from other mental states and behaviors—both when it comes to simply understanding people and when it comes to moral assessments of mental states and of actions. After all, mental illness is just like diabetes, while other human conditions are not. That sounds like a huge difference. I (...) think this suggestion is misleading. (shrink)

The doyen of living English philosophers, by these reflections, took hold of and changed the outlook of a good many other philosophers, if not quite enough. He did so, essentially, by assuming that talk of freedom and responsibility is talk not of facts or truths, in a certain sense, but of our attitudes. His more explicit concern was to look again at the question of whether determinism and freedom are consistent with one another -- by shifting attention to certain personal (...) rather than moral attitudes, first of all gratitude and resentment. In the end, he arrived at a kind of Compatibilist or, as he says, Optimist conclusion. That is no doubt a recommendation but not the largest recommendation of this splendidly rich piece of philosophy. (shrink)

In this article I ask whether elaborated and systematized delusions emerging in the context of schizophrenia have the potential for epistemic innocence. Cognitions are epistemically innocent if they have significant epistemic benefits that could not be attained otherwise. In particular, I propose that a cognition is epistemically innocent if it delivers some significant epistemic benefit to a given agent at a given time, and if alternative cognitions delivering the same epistemic benefit are unavailable to that agent at that time. Elaborated (...) and systematized delusions in schizophrenia are typically false and exemplify failures of rationality and self-knowledge. Empirical studies suggest that they may have psychological benefits by relieving anxiety and enhancing meaningfulness. Moreover, these delusions have been considered as adaptive in virtue of the fact that they enable automated learning to resume after a significant disruption caused by incorrect prediction-error signalling. I argue that such psychological benefits and adaptive features also have positive epistemic consequences. More precisely, delusions can be a means to restoring epistemic functionality in agents who are overwhelmed by hypersalient experiences in the prodromal stage of psychosis. The analysis leads to a more complex view of the epistemic status of delusions than is found in the contemporary philosophical literature and has some implications for clinical practice. 1 Introduction2 Types of Delusions3 What Is Wrong with Elaborated and Systematized Delusions?4 Finding Life Meaningful5 Learning Resumed6 Epistemic Innocence7 Epistemic Benefit8 No Alternatives9 Conclusions and Implications.

A person suffering a mental illness or disorder may differ dramatically from his or her previous well self. Family and close friends who knew the person before the onset of illness tend to regard the illness as obscuring their loved one's true self and see the goal of treatment as the restoration of that self. ‘He is not really like this,’ they will say with increasing desperation. Treatment teams and others, who have no acquaintance with the person when well, respond (...) to what they see in front of them and do sometimes make harmful judgments of character based on the person's presentation when ill.

Whether your scepticism is as absolute and sincere as you claim is something we shall learn later on, when we end this little meeting: we’ll then see whether you leave the room through the door or the window; and whether you really doubt that your body has gravity and can be injured by its fall—which is what people in general think on the basis of their fallacious senses and more fallacious experience. What Could Be more dissimilar than a well-argued philosophical (...) thesis and a psychiatric delusion? Compare, for instance, Hume’s (1739) view that the self is nothing more than a “bundle” of perceptions with the psychiatric patient’s view that the thoughts in his head belong to someone else. Or, compare the .. (shrink)

This article examines the supposedly incomprehensibility of schizophrenic delusions. According to the contemporary classificatory systems (DSM-IV-TR and ICD-10), some delusions typically found in schizophrenia are considered bizarre and incomprehensible. The aim of this article is to discuss the notion of understanding that deems these delusions incomprehensible and to see if it is possible to comprehend these delusions if we apply another notion of understanding. First, I discuss the contemporary schizophrenia definitions and their inherent problems, and I argue that the notion (...) of incomprehensibility in these definitions rests heavily on Jaspers’ notions of understanding and empathy. Secondly, I discuss two Wittgensteinian attempts to comprehend bizarre delusions: (a) Campbell’s proposal to conceive delusions as framework propositions and (b) Sass’s suggestion to interpret delusions in the light of solipsism. Finally, I discuss the phenomenological conception of schizophrenia, which conceives delusion formation as resulting from alterations of the structure of experiencing and from underlying self-disorders. I argue that although a psychological understanding that seeks to grasp meaning in terms of motivations, desires, and other more straightforward psychological connections between mental states is impossible in schizophrenia, we can in fact have a philosophical understanding of the schizophrenic world and of the emergence of delusions typically found in schizophrenia.

Assertive community treatment (ACT) is a widely propagated team approach to community mental health care that ‘assertively’ engages a subgroup of individuals with severe mental illness who continuously disengage from mental health services. It involves a number of interested parties – including clients, carers, clinicians and managers. Each operates according to perceived ethical principles related to their values, mores and principles. ACT condenses a dilemma that is common in psychiatry. ACT proffers social control whilst simultaneously holding therapeutic aspiration. The clients’ (...) perspective of this dilemma was studied in interviews with 12 clients using the ‘grounded theory’ approach. Results suggest that clients’ disengagement is as much a historical and cultural phenomenon as a result of lack of insight. Many clients had experienced rejection of early help–seeking behaviour and all had been subject to coercive interventions. These coercive interventions were experienced as an attack on identity. All felt that their voice had not been listened to in previous interactions with psychiatric services. Consequentially the clients had an increased level of arousal around issues of power, which needs to be incorporated when examining the ethics of community psychiatry. Traditional notions of the difference between persuasion and coercion – for example – may need to be adapted for this client group. Results are compared with the provider perspective. We conclude that the perspectives differ on two key dimensions. Such an empirical approach to examining psychiatric ethics may ensure that we incorporate the subjectivities of various interested parties in the clinical decision–making process. (shrink)

Scientific cognition is a hard-won achievement, both from a historical point of view and a developmental point of view. Here, I review seven facets of lay cognition that run counter to, and often impede, scientific cognition: incompatible folk theories, missing ontologies, tolerance for shallow explanations, tolerance for contradictory explanations, privileging explanation over empirical data, privileging testimony over empirical data, and misconceiving the nature of science itself. Most of these facets have been investigated independent of the others, and I propose directions (...) for future research that might integrate them so as to explore potential commonalities among seemingly disparate obstacles to science learning, as well as potential strategies for bridging lay cognition and scientific cognition in the context of science education.

Cognitive psychologists have recently identified alterations in perception and reasoning that contribute to the formation and maintenance of beliefs that happen to be delusional. Clinically significant delusions, however, are often deeply unusual. An account of their formation and maintenance must explain not merely how someone can come to hold false or uncommon beliefs, but also how someone can arrive at beliefs that seem profoundly improbable and even bizarre. This paper uses the philosophical concepts of the Bedrock and the Background to (...) provide an account of that foundational, nonrepresentational, non–rule-governed, dispositional structure of everyday understanding that underpins both our perception and our reasoning. The central claim is that the formation and maintenance of delusions becomes intelligible once they are seen to reflect disturbances to this foundational dispositional structure. Different dimensions of the Background are described along with the delusions that might follow from distortions to these dimensions. We challenge the assumption of much recent cognitive psychological theorizing that delusions can be understood as explanations of unusual experiences or as the product of hasty reasoning. Finally, the implications of the theory for the therapy of the delusional patient are briefly discussed. (shrink)

We have made huge progress in understanding the biology of mental illnesses, but comparatively little in interpreting them at the psychological level. The eminent philosopher Jonathan Glover believes that there is real hope of progress in the human interpretation of disordered minds. -/- The challenge is that the inner worlds of people with psychiatric disorders can seem strange, like alien landscapes, and this strangeness can deter attempts at understanding. Do people with disorders share enough psychology with other people to make (...) interpretation possible? To explore this question, Glover tackles the hard cases—the inner worlds of hospitalized violent criminals, of people with delusions, and of those diagnosed with autism or schizophrenia. Their first-person accounts offer glimpses of inner worlds behind apparently bizarre psychiatric conditions and allow us to begin to learn the “language” used to express psychiatric disturbance. Art by psychiatric patients, or by such complex figures as van Gogh and William Blake, give insight when interpreted from Glover’s unique perspective. He also draws on dark chapters in psychiatry’s past to show the importance of not medicalizing behavior that merely transgresses social norms. And finally, Glover suggests values, especially those linked with agency and identity, to guide how the boundaries of psychiatry should be drawn. -/- Seamlessly blending philosophy, science, literature, and art, Alien Landscapes? is both a sustained defense of humanistic psychological interpretation and a compelling example of the rich and generous approach to mental life for which it argues.

People experiencing mental distress and illness are frequently on the receiving end of stigma, epistemic injustice, and social isolation. A range of strategies are required to alleviate the subsequent marginalisation. We ran a series ‘philosophy of mind’ workshops, in partnership with a third-sector mental health organisation with the aim of using philosophical techniques to challenge mental health stigma and build resources for self-understanding and advocacy. Participants were those with lived experience of mental distress, or unusual beliefs and experiences; mental health (...) advocates; and mental health service providers. We draw on a shared perspective as a participant and facilitator of the workshop series to assess their impact. We discuss the following benefits: the opportunity for structured discussion of experiences and models; dialogue across different mental health backgrounds; the potential to reduce self-stigma and to increase self-understanding and advocacy; and the potential to alleviate epistemic injustice. We invite researchers and mental health practitioners to consider further opportunities to investigate the potential benefits of philosophy groups in mental health settings to establish whether they generalise.

In this paper we review two debates in the current literature on clinical delusions. One debate is about what delusions are. If delusions are beliefs, why are they described as failing to play the causal roles that characterise beliefs, such as being responsive to evidence and guiding action? The other debate is about how delusions develop. What processes lead people to form delusions and maintain them in the face of challenges and counter-evidence? Do the formation and maintenance of delusions require (...) abnormal experience alone, or also reasoning biases or deficits? We hope to show that the focus on delusions has made a substantial contribution to the philosophy of the mind and continues to raise issues that are central to defining the concept of belief and gaining a better understanding of how people process information and learn about the world.
