Delusions are a common symptom of schizophrenia, dementia and other psychiatric disorders. Though most English dictionaries define a delusion as a false opinion or belief, there is currently a lively debate about whether delusions are really beliefs and indeed, whether they are evenirrational. The book is an interdisciplinary exploration of the nature of delusions. It brings together the psychological literature on the aetiology and the behavioural manifestations of delusions, and the philosophical literature on belief ascription and rationality. The thesis of the book is that delusionsare continuous with ordinary beliefs, a thesis that could have not only significant theoretical implications for debates in the philosophy of mind and psychology, but also practical implications for psychiatric classification and the clinical treatment of subjects with delusions. By bringing together recent work in philosophy of mind, cognitive psychology and psychiatry, the book offers a comprehensive review of the philosophical issues raised by the psychology of normal and abnormal cognition, defends the doxastic conception of delusions, and develops a theory about therole of judgements of rationality and self-knowledge in belief ascription.
