Since Auschwitz we know what man is capable of. And since Hiroshima we know what is at stake.

I understood how a man who has nothing left in this world still may know bliss, be it only for a brief moment, in the contemplation of his beloved.

What man actually needs is not a tensionless state but rather the striving and struggling for some goal worthy of him. What he needs is not the discharge of tension at any cost, but the call of a potential meaning waiting to be fulfilled by him.

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

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.

Happiness cannot be attained by wanting to be happy - it must come as the unintended consequence of working for a goal greater than oneself.

Don't aim at success — the more you aim at it and make it a target, the more you are going to miss it. For success, like happiness, cannot be pursued; it must ensue, and it only does so as the unintended side-effect of one's personal dedication to a cause greater than oneself or as the by-product of one's surrender to a person other than oneself. Happiness must happen, and the same holds for success: you have to let it happen by not caring about it. I want you to listen to what your conscience commands you to do and go on to carry it out to the best of your knowledge. Then you will live to see that in the long run — in the long run, I say — success will follow you precisely because you had forgotten to think of it.
