This book presents a unique examination of mental illness. Though common to many mental disorders, delusions result in actions that, though perhaps rational to the individual, might seem entirely inappropriate or harmful to others. This book shows how we may better understand delusion by examining the nature of compulsion.

The essays in this volume offer a thorough discussion of the relationship between addiction and rationality. This book-length treatment of the subject includes contributions from philosophers, psychiatrists, neurobiologists, sociologists and economists. Contrary to the widespread view that addicts are subject to overpowering and compulsive urges, the authors in this volume demonstrate that addicts are capable of making choices and responding to incentives. At the same time they disagree with Gary Becker's argument that addiction is the result of rational choice. The volume offers an exposition of the neurophysiology of addiction, a critical examination of the Becker theory of rational addiction, an argument for a 'visceral theory of addiction', a discussion of compulsive gambling as a form of addiction, several discussions of George Ainslie's theory of hyperbolic discounting, analyses of social causes and policy implications, and an investigation of the problem of relapse.

Traditionally, obsessive-compulsive disorder has been classified as an anxiety disorder, but there is increasing evidence that it has schizotypal features ? in other words it is a belief disorder. This book describes the ways in which reasoning can be applied to OCD for effective treatment regimes. It moves comprehensively through theoretical, experimental, clinical and treatment aspects of reasoning research, and contains a detailed treatment manual of great value to practitioners, including assessment and treatment protocols and case studies

The concept of rationality is a common thread through the human and social sciences — from political science to philosophy, from economics to sociology, and from management science to decision analysis. But what counts as rational action and rational behavior? José Luis Bermúdez explores decision theory as a theory of rationality. Decision theory is the mathematical theory of choice and for many social scientists it makes the concept of rationality mathematically tractable and scientifically legitimate. Yet rationality is a concept with several dimensions and the theory of rationality has different roles to play. It plays an action-guiding role (prescribing what counts as a rational solution of a given decision problem). It plays a normative role (giving us the tools to pass judgment not just on how a decision problem was solved, but also on how it was set up in the first place). And it plays a predictive/explanatory role (telling us how rational agents will behave, or why they did what they did). This controversial but accessible book shows that decision theory cannot play all of these roles simultaneously. And yet, it argues, no theory of rationality can play one role without playing the other two. The conclusion is that there is no hope of taking decision theory as a theory of rationality.

Among the many practical failures that threaten us, weakness of will or akrasia is often considered to be a paradigm of irrationality. The eleven new essays in this collection, written by an excellent international team of philosophers, some well-established, some younger scholars, give a rich overview of the current debate over weakness of will and practical irrationality more generally. Issues covered include classical questions such as the distinction between weakness and compulsion, the connection between evaluative judgement and motivation, the role of emotions in akrasia, rational agency, and the existence of the will. The also include new topics, such as group akrasia, strength of will, the nature of correct choice, the structure of decision theory, the temporality of prudential reasons, and emotional rationality. Because these questions cut across philosophy of mind and ethics, the collection will be essential reading for scholars, postgraduates, and upper-level undergraduates in both these fields.
