     People turn to magic (魔力) chiefly as a form of insurance-that is, they use it along with actions that

actually bring results.For example, hunters may use a hunting charm (咒语). But they also use their

hunting skills and knowledge of animals. The charm may give hunters the extra confidence they need to

hunt even more successfully than they would without it.If they shoot a lot of game (猎物), they credit

the charm for their success. Many events happen naturally without magic. Crops grow without it, and

sick people get well without it.But if people use magic to bring a good harvest or to cure a patient, they

may believe the magic was responsible.

     People also tend to forget magic's failures and to be impressed by its surface successes. They may

consider magic successful if it appears to work only 10 per cent of the time. Even when magic fails,

people often explain the failure without doubting the power of the magic. They may say that the magician

made a mistake in reciting the spell or that another magician cast a more powerful spell against the

magician.

     Many anthropologists (人类学家) believe that people have faith in magic because they feel a need to

believe in it. People may turn to magic to reduce their fear and uncertainty if they feel they have no

control over the outcome of a situation. For example, farmers use knowledge and skill when they plant

their fields. But they know that weather, insects, or diseases might ruin the crops. So farmers in some

societies may also plant a charm or perform a magic rite to ensure a good harvest.
