“As a professor in two fields, neurology and psychiatry, I am fully aware of the extent to which man is subject to biological, psychological and sociological conditions. But in addition to being a professor in two fields I am a survivor of four camps - concentration camps, that is - and as such I also bear witness to the unexpected extent to which man is capable of defying and braving even the worst conditions conceivable.”

“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.”

“I am aware that the battle I am fighting is a petty one, but I am also aware that in order to win that which is great, you must first win that which is small.”

“I am from there. I am from here.I am not there and I am not here.I have two names, which meet and part,and I have two languages.I forget which of them I dream in.”

“While I am interested both in economics and in philosophy, the union of my interests in the two fields far exceeds their intersection”

“The irony of man's condition is that the deepest need is to be free of the anxiety of death and annihilation; but it is life itself which awakens it, and so we must shrink from being fully alive.”
