The book by psychiatrist, psychologist, neurologist, philosopher and founder of the Third Vienna School of Psychotherapy Viktor Frankl includes 13 articles and lectures he wrote over 60 years of work on logotherapy, a psychotherapeutic method that focuses on man’s search for the meaning of existence. In the book the origin and development of logotherapy is traced, its theoretical justification and methods of practical application are given. In addition, the collection is extremely interesting as a document of the era, as a testimony of a surviving eyewitness and participant in the tragic events of the 20th century, called upon by his own life and fate to test and confirm the theoretical provisions of his conclusions. The biography of Viktor Frankl, who went through the horror of the Nazi death camps, serves as the clearest evidence of his conclusions that the main life force is the human will to meaning. This book is a long-awaited event for logotherapists, psychotherapists, psychologists, teachers, as well as for a wide range of readers who think about the meaning of life and ways to find it.
