The search is what anyone would undertake if he were not sunk in the everydayness of his own life.
To become aware of the possibility of the search is to be onto something. Not to be onto something is to be in despair.
The movies are onto the search, but they screw it up. The search always ends in despair. They like to show a fellow coming to himself in a strange place — but what does he do? He takes up with the local librarian, sets about proving to the local children what a nice fellow he is, and settles down with a vengeance. In two weeks time he is so sunk in everydayness that he might just as well be dead.
