The title of the book "On the Meaning of Life" accurately and succinctly reflects the essence and main theme of Viktor Frankl's human and scientific searches. In it, the reader will find three lectures that the famous psychiatrist and psychotherapist delivered in 1946 at the People's University of Vienna, which have not been published before in Russian. This unique testimony of a former prisoner of a concentration camp who went through the most difficult trials and retained the will to live is a valuable part of the legacy of Viktor Frankl, whose works around the world and at any time do not lose their relevance.
