Book excerpt: This book is a seminal contribution to applied and clinical logotherapy and existential analysis from a philosopher who is also a practitioner. It covers twelve essential topics and themes, drawing on Dr Viktor Frankl’s Viennese School of philosophical psychology, from therapeutic techniques, such as dereflection, paradoxical intention, and Socratic dialogue, to the mass neurotic triad of aggression, addiction, and depression. It also discusses the cultural malaise of anger, anxiety, and boredom, and the theory and therapy of mental disorders such as neuroses and psychoses, criminality, and suicidality. This unique publication, which is both theoretical and practical, is intended primarily for psychotherapists, philosophers, psychologists and psychiatrists, but will also appeal to parents, teachers, students, and indeed anyone who wishes to live a life of meaning and mental health.
