Happiness cannot be pursued; it must ensue. One must have a reason to “be happy.” Once the reason is found, however, one becomes happy automatically.
A human being is not one in pursuit of happiness but rather in search of a reason to become happy, last but not least, through actualizing the potential meaning inherent and dormant in a given situation.
This need for a reason is similar in another specifically human phenomenon—laughter. If you want anyone to laugh you have to provide him with a reason, e.g., you have to tell him a joke. In no way is it possible to evoke real laughter by urging him, or having him urge himself, to laugh. Doing so would be the same as urging people posed in front of a camera to say “cheese,” only to find that in the finished photographs their faces are frozen in artificial smiles.
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.
