Philosopher Viktor E. Frankl lost his family but survived the Nazi death camps of WWII. The following quotes come from Man's Search For Meaning ; Washington Square Press, Simon and Schuster, New York, 1963.

        "Everything can be taken from a man but ...the last of the human freedoms - to choose one's attitude in any given set of circumstances, to choose one's own way."

        "There is also purpose in life which is almost barren of both creation and enjoyment and which admits of but one possibility of high moral behavior: namely, in man's attitude to his existence, an existence restricted by external forces."
