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.

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.

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.

Is faith delusion? Is religion bad for your health? How, in a scientifically and technologically advanced age, can people still believe in God/spirit/'other'? Clearly not all believers are primitive and ill-educated; an alternative explanation is that they must be mad, or at least severely neurotic (as suggested by Freud). This book starts by looking at, and giving reasons for, the connection and the division between Christian faith and psychiatry. It asks whether science challenges Christians involved with psychiatry, as patients or professionals, and whether the spiritual needs of patients are recognised. The author examines the scope and use of the neuro-sciences and considers cause and effect, natural selection and determinism. He explores the overlap (and the difference) between psychiatric symptoms and religious belief, the possible association between demon possession and mental illness, and the idea that some people are intrinsically religious and some are not. The variations of personality are examined, with their implications for belief. Posited as a statement, that faith is delusion is always hostile, but outcome studies (reviewed here) show that in general religious belief and practice convey good mental health. Religious faith and mental illness are different, and their concepts come from different world-views. A consideration of them in relation to each other is long overdue. The author is a former Professor of Psychiatry and President of the Royal College of Psychiatrists, and has also been Chairman of their Spirituality and Psychiatry Special Interest Group, so is exceptionally well qualified to address the subject. Although the book is technically proficient, it is aimed at the general reader and is illustrated with stories, brief case histories and anecdotes.
