Frankl's Man's Search for Meaning sold over 10 million copies and was translated into over 30 languages and was deemed by a survey of the Library of Congress one of "the ten most influential books in America". This volume introduces and presents translations of a number of important but less well-known writings by Viktor Frankl, translated from the original German, in which he forthrightly relates psychology to religious concepts. These cast a strong, new light on the generally received understanding of Frankl's contribution to psychology – "logotherapy" – and its relationship to the soul and universal ethics.
