This book proposes to open up the debate on mental disorders, to get people interested and talking, and to get them thinking. For example, what is schizophrenia? Why is it so common? Why does it affect human beings and not animals? What might this tell us about our mind and body, language and creativity, music and religion? What are the boundaries between mental disorder and 'normality'? Is there a relationship between mental disorder and genius? These are some of the difficult but important questions that this book confronts, with the overarching aim of exploring what mental disorders can teach us about human nature and the human condition. Dr Neel Burton qualified in neuroscience and medicine from the University of London and is a Member of the Royal College of Psychiatrists. He is the the author of several books, including a prize-winning textbook of psychiatry and a prize-winning self-help book for people with schizophrenia. He lives and teaches in Oxford.
