Fear and its companion pain are two of the most useful things that men and animals possess， if they are proper1y used. If fire did not hurt when it burnt， children would p1ay 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 it to keep away from the fire that had burn it before. A real1y 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 and die out.
In our first sentence we suggested that fear ought to be proper1y 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： an airplane may crash on your house， or ants may eat away some of the beams in your roof so that the latter falls 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 well.
In some cases， however， you decide that there is nothing that you can do to avoid the danger. For examp1e， you cannot prevent an airplane crashing onto your house. 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.
