The medical profession's classic prescription for coping with such predicaments, Primum non nocere (First, do no harm), sounds better than it is. In fact, it fails to tell us precisely what we need to know: What is harm and what is help? However, two things about the challenge of helping the helpless are clear. One is that, like beauty and ugliness, help and harm often lie in the eyes of the beholder--in our case, in the often divergently directed eyes of the benefactor and his beneficiary. The other is that harming people in the name of helping them is one of mankind's favorite pastimes.
