'A new approach to mental disorder. Randolph Nesse's insightful book suggests that conditions such as anxiety and depression have a clear evolutionary purpose ... This intriguing book turns some age-old questions about the human condition upside down' Tim Adams, Observer One of the world's most respected psychiatrists provides a much-needed new evolutionary framework for making sense of mental illness With his classic book Why We Get Sick, Randolph Nesse established the field of evolutionary medicine. Now he returns with a book that transforms our understanding of mental disorders by exploring a fundamentally new question. Instead of asking why certain people suffer from mental illness, Nesse asks why natural selection has left us with fragile minds at all. Drawing on revealing stories from his own clinical practice and insights from evolutionary biology, Nesse shows how negative emotions are useful in certain situations, yet can become excessive. Anxiety protects us from harm in the face of danger, but false alarms are inevitable. Low mood prevents us from wasting effort in pursuit of unreachable goals, but it often escalates into pathological depression. Other mental disorders, such as addiction and anorexia, result from the mismatch between modern environments and our ancient human past. Taken together, these insights and many more help to explain the pervasiveness of human suffering, and show us new paths for relieving it. Good Reasons for Bad Feelings will fascinate anyone who wonders how our minds can be so powerful, yet so fragile, and how love and goodness came to exist in organisms shaped to maximize Darwinian fitness.

Depression is a major cause of morbidity throughout the world. Given that between 8 and 12% of the population (in most countries) will suffer from depression at some point in their lives, it is clearly a significant public health problem. As our knowledge of this illness has expanded in recent years, it has become clear that depression can no longer be viewed as a simple disorder of the brain. It has to be seen as a series of behavioural and biological changes that span mind, brain, genes, and body - indeed affecting both psychological and physical health. This book brings together world leaders in research on depression, to discuss, for the first time, in an interdisciplinary setting, both classical and innovative ideas to understand this devastating disorder. It presents neurobiological, psychological, genetic and evolutionary models, with a particular emphasis on the mechanisms linking the brain to the endocrine and the immune systems, and therefore linking depression to physical health. Opening with a powerful, personal, account of depression, that conveys something of the all-consuming, debilitating, nature of this illness, the book then presents cutting edge research from those at the frontiers of work in this area. The book will be valuable for all psychiatrists, clinical psychologists and neuroscientists seeking a state-of-the-art of this global problem
