Man’s Search for Meaning was published by Viktor Frankl in 1946. Frankl is the founder of logotherapy. The most important force in a man’s life is his desire to find meaning. While Freud speaks of a “will to pleasure” and Adler speaks of a “will to power,” Frankl focuses on a “will to meaning”, as the primary motivational force in man.
The book sold over 10 million copies at the time of Frankl’s death in 1997, and continues to this day to inspire many to find significance in the very act of living. The success of the book may be a symptom of the "mass neurosis of modern times" since the title promised to deal with the question of life's meaningfulness.
