     I had an experience some years ago, which taught me something about the ways in which people

make a bad situation worse by blaming themselves. One January, I had to hold two funerals on

successive days for two elderly women in my community. Both had died " full of years", as the Bible

would say. Their homes happened to be near each other, so I paid condolence(吊唁) calls on the

two families on the same afternoon.

     At the first home, the son of the deceased(已故的)woman said to me, " If only I had sent my

mother to Florida and gotten her out of this cold and snow, she would be alive today. It's my fault

that she died." At the second home, the son of the other deceased woman said, " If only I hadn't

insisted on my mother's going to Florida, she would be alive today.. that long airplane ride, the sudden

change of climate, was more than she could take. It's my fault that she's dead."

     You see that any time there is a death, the survivors will feel guilty. Because the course of action

they took turned out bad, they believe that the opposite course-keeping Mother at home, putting off

the operation-would have turned out better. After all, how could it have turned out any worse?

There are seem to be two elements involved in our willingness to feel guilty. The first is our pressing

need to believe that the world makes sense, that there is a cause for every effect and a reason for

everything that happens that leads us to find patterns and connections both where they really exist

and where they exist only in our minds.

     The second element is the view that we are the cause of what happens , especially the bad things

that happen. It seems to be a short step from believing that every event has a cause to believe that

every disaster is our fault. The roots of this feeling may lie in our childhood.

     A baby comes to think that the world exists to meet his needs, and that he makes everything happen

in it. He wakes up in the morning and summons the rest of the world to its tasks. He cries, and someone

comes to attend to him. When he is hungry, people feed him , and when he is wet, people change him.

Very often, we do not completely outgrow that childish view that our wishes cause things to happen.
