  【甲】晏子至,楚王赐晏子酒,酒酣,吏二缚一人诣王。王曰:“缚者曷为者也?”对曰:“齐人也,坐盗。”王视晏子曰:“齐人固善盗乎?”晏子避席对曰:“婴闻之,橘生淮南则为橘,生于淮北则为枳,叶徒相似,其实味不同。所以然者何?水土异也。今民生长于齐不盗,入楚则盗,得无楚之水土使民善盗耶?”王笑曰:“圣人非所与熙也,寡人反取病焉。”

     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 bumt

away. Similarly , if pain existed but fear did not,a child would bum 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 waming;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.
