Problem:
Roger Smith, a quite competent swimmer, is out for a leisurely stroll. During the course of his walk he passes by a deserted pier from which a teenage boy who apparently cannot swim has fallen into the water. The boy is screaming for help. Smith recognizes that there is absolutely no danger to himself if he jumps in to save the boy; he could easily succeed if he tried.
Nevertheless, he chooses to ignore the boy's cries. The water is cold and he is afraid of catching a cold -- he doesn't want to get his good clothes wet either. "Why should I inconvenience myself for this kid," Smith says to himself, and passes on.
Does Smith have a moral obligation to save the boy? If so, should he have a legal obligation ["Good Samaritan" laws] as well?
