Frankl, V. (1946). Man's search for meaning. Beacon Press
Frankl's theory—known as logotherapy (from the Greek word logos, "meaning")—holds that our primary drive in life is not pleasure, as Freud maintained, but the discovery and pursuit of what we personally find meaningful. In this book he talks about his experiences as a concentration camp inmate and describes his psychotherapeutic method of finding a reason to live.
