Despite surviving 3 camps in which he lost his family and the manuscript comprising his life's work, he would go on to reshape modern psychotherapy on the basis of his suffering and the meaning he found in it - as exemplified by the following quote from his 1946 book Man's Search for Meaning:

"We must never forget that we may also find meaning in life even when confronted with a hopeless situation, when facing a fate that cannot be changed. For what then matters is to bear witness to the uniquely human potential at its best, which is to transform a personal tragedy into triumph, to turn one's predicament into a human achievement."
