Meaning cannot be given but found. Viktor Frankl (1905-1977), thinker, professor of neurology and psychiatry, Viennese Jew, father of logotherapy theory and the psychotherapeutic approach to finding meaning in life, in practice. Shortly after his release from three years in concentration camps in Nazi Germany, aged forty, he wrote Man Searching for Meaning for nine consecutive days. In his monumental essay, which is now seeing the light of day in a renewed and up-to-date translation, Frankel concludes that it is possible to take away from a person all but one freedom: to choose how to react in any circumstances; that it is a person's duty to find meaning in his life; that the way in which he accepts his fate and deals with his suffering allows such a meaning; That the person he will become is the result of an internal decision and not an external reality. The book has sold more than 12 million copies and is considered one of the ten most influential books in the world. Frankel published 40 books that were published in more than 50 languages.
