A human being is not one thing among others; things determine each other, but man is ultimately self-determining. What he becomes - within the limits of endowment and environment- he has made out of himself. In the concentration camps, for example, in this living laboratory and on this testing ground, we watched and witnessed some of our comrades behave like swine while others behaved like saints. Man has both potentialities within himself; which one is actualized depends on decisions but not on conditions.

A man's concern, even his despair, over the worthwhileness of life is an existential distress but by no means a mental disease.

In a last violent protest against the hopelessness of imminent death, I sensed my spirit piercing through the enveloping gloom. I felt it transcend that hopeless, meaningless world, and from somewhere I heard a victorious "Yes" in answer to my question of the existence of an ultimate purpose. At that moment a light was lit in a distant farmhouse, which stood on the horizon as if painted there, in the midst of the miserable gray of a dawning morning in Bavaria. "Et lux in tenebris lucet"-and the light shineth in the darkness.

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.

For the meaning of life differs from man to man, from day to day and from hour to hour. What matters, therefore, is not the meaning of life in general but rather the specific meaning of a person's life at a given moment.

Human kindness can be found in all groups, even those which as a whole it would be easy to condemn.

Every human being has the freedom to change at any instant.
