What sort of mental state is a delusion? What causes delusions? Why are delusions pathological? This book examines these questions, which are normally considered separately, in a much-needed exploration of an important and fascinating topic, Kengo Miyazono assesses the philosophical, psychological and psychiatric literature on delusions to argue that delusions are malfunctioning beliefs. Delusions belong to the same category as beliefs but - unlike healthy irrational beliefs - fail to play the function of beliefs. Delusions and Beliefs: A Philosophical Inquiry will be of great interest to students of philosophy of mind and psychology and philosophy of mental disorder, as well as those in related fields such as mental health and psychiatry.

The book is an interdisciplinary exploration of the nature of delusions. It brings together recent work in philosophy of mind, cognitive psychology and psychiatry, offering a comprehensive review of the philosophical issues raised by the psychology of normal and abnormal cognition.

Schizophrenia has been investigated predominantly from psychological, psychiatric and neurobiological perspectives. This text examines it from a philosophical point of view.

A Behavioral Scientist Notable Book of 2021 A Next Big Idea Club Best Nonfiction of 2021 From the New York Times best-selling author and host of Hidden Brain comes a thought-provoking look at the role of self-deception in human flourishing. Self-deception does terrible harm to us, to our communities, and to the planet. But if it is so bad for us, why is it ubiquitous? In Useful Delusions, Shankar Vedantam and Bill Mesler argue that, paradoxically, self-deception can also play a vital role in our success and well-being. The lies we tell ourselves sustain our daily interactions with friends, lovers, and coworkers. They can explain why some people live longer than others, why some couples remain in love and others don’t, why some nations hold together while others splinter. Filled with powerful personal stories and drawing on new insights in psychology, neuroscience, and philosophy, Useful Delusions offers a fascinating tour of what it really means to be human.

How, in a scientifically and technologically advanced age, can people still believe in God? Andrew Sims examines both the connection and the division between Christian faith and psychiatry.

This book represents a unique collection of ideas and empirical data provided by leading experts in a diversity of disciplines: cognitive psychologists involved with normal mechanisms of decision-making and information processing, social psychologists concerned with normal aspects of perception, as well as clinical psychologists, anthropologists, and psychiatrists. Each offers perspectives on such questions as: What criteria should be used to identify, describe, and classify delusions? How can delusional individuals be identified? What distinguishes delusions from normal beliefs? Also examined in this volume are the personal, interpersonal, and situational variables predisposing certain people to developing delusions; the ways in which delusions are perpetuated; and approaches to changing a particular delusional belief.

The authors offer cogent reviews of the literature pertaining to the formation and maintenance of delusions, but the most substantial parts of the monograph expound the empirical inquiries which they and their colleagues have carried out in recent years. Most of the research has been published elsewhere, but such is the relevance of the experiments cited to the whole schema that the monograph has unique value. It is a synthesis which portrays the contribution to date of cognitive science to the biology and psychopathology of delusional thinking, and convincingly demonstrates that this way of looking at things has a considerable future. There are important implications for therapy as well as for hypothesis formulation. The monograph is attractively written, and the authors present their claims with exemplary modesty. The whole tenor of their approach gives weight to the conviction that here we have a story that must be taken seriously. It is a significant book, and I warmly commend it to all those with an interest in the future of psychopathology, and especially to psychiatrists who wish to advance their understanding of mental states and avoid stagnating with outworn dogma." - Robert Cawley, University of London in British Journal of Psychiatry Delusions are a key symptom of psychosis and yet there is no single book which considers delusions from a psychological perspective. In part this is because the syndrome of schizophrenia has captured the attention of many workers, and in part because delusions, as private mental phenomena, are not well suited to purely behavioural or observational methods of enquiry. For the past two decades, however, cognitive psychology has been in its ascendancy and delusions, as beliefs, are particularly amenable to investigation applying cognitive concepts and methods. Within this framework, it is possible to consider continuities between delusional and ordinary beliefs, as well as to seek to identify differences. This book, therefore, uniquely presents a psychological model of delusions, employing the neglected strategy of single symptom research and the tools of cognitive psychology
