Although men are not laboratory animals, they often behave as though they are.  Sometimes they are put in cages and treated like rats, manipulated and sacrificed at the will of their masters.  But many times the cage has an open door, and a man has only to walk out if he wishes.  If he does not, it is usually his script which keeps him there.  That is familiar and reassuring, and after looking out at the great world of freedom with all its joys and dangers, he turns back to the cage with its buttons and levers, knowing that if he keeps busy pushing them, and pushes the right one at the right time, he will be assured of food, drink and an occasional thrill.  But always such a caged person hopes or fears that some force greater than himself, the Great Experimenter or the Great computer, will change or end it all.
