Fear and its companion pain are two of the most useful things that men and animals possess,if they are
properly used.If fire did not hurt when it burnt,children would play it until their hands were burnt away.
Similarly,if pain existed but fear did not,a child would burn itself again and again,because fear would not
warn the child to keep away from the fire that had burnt him or her before.A really fearless soldier-and
some do exist-is not a good soldier because he is soon killed；and a dead soldier is of no use to his army.
Fear and pain are therefore two guards without which men and animals might soon die out.
In our first sentence we suggested that fear ought to be properly used.If,for example,you never go out
of your house because of the danger of being knocked down and killed in the street by a car,you are letting
fear rule you too much.Even in your house you are not absolutely safe:a plane may crash on your house,or
ants may eat away some of the wood in your roof,and they later may fall on you,or you may get cancer!
The important thing is not to let fear rule you,but instead to use fear as your servant and guide.Fear will
warn you of dangers；then you have to decide what action to take.
In many cases,you can take quick and successful action to avoid the danger.For example,you see a car
coming straight towards you；fear warns you,you jump out of the way,and all is OK.
In some cases,however,you decide that there is nothing that you can do to avoid the danger.For
example,you cannot prevent a plane from crashing into your house,and you may not want to go and live
in a desert where there are no plants.In this case,fear has given you its warning；you have examined it and
decided on your course of action,so fear of this particular danger is no longer of any use to you,and you
have to try to overcome it.
