Good Reasons for Bad Feelings

Written by a founder of evolutionary medicine, this book reframes mental disorders as consequences of evolved emotional systems. Drawing on decades of clinical experience and evolutionary biology, it explains how feelings that once solved survival problems can become harmful in modern contexts.

Topics include anxiety as a protective alarm prone to false positives, low mood as an energy-conserving response that may escalate into depression, and how modern environments contribute to addiction and disordered eating. The book also considers sexual disorders and why genes linked to schizophrenia persist.

Readers get a clear conceptual framework linking biology and behavior, case-based clinical insight, and practical perspectives for understanding and responding to emotional distress.
