A Society Without a Formal Authority

In the seventeenth century, European soldiers who came across soreS'Indian groups in the western Great Lakes round that several native tdbes （部落） were living in the area without a formal leadership system. They appeared to be "quite fridendly with each other without a formal authority"

Not only did the Indians appear to lack a formal system.of authority, but they also deeply hated any efforts to control their actions. All members of the tribes knew what was required of them by lifelong （一生的） familiarity with the tasks of the area. These tasks tended to be simple, since the indians' rate of social change was slow. Thus, although subgroups such as soldiers had recognized leaders, no real authority was required.

Rather than giving direct orders （which were considered rough）, members of the tribes would arouse others to action by examples.

It would be difficult, if not impossible, to carry out such asystem in our own society.Most of us have grown up under one authority or another for as long as we can remember. Our parents, our teachers, our bosses, our government all have the recognized right under certain conditions to tell us what to do. The authority is so much a part of our culture that it is hard for us to imagine a workable society without it. We have been used to relying on authority to get things done and would probably be uncomfortable with the Indian methods of examples on a large scale.Of course, the major reason why the Indian system would not be suitable for us is that our society is too large. The number of tasks that various members of our scciety have to perform. often under tight time and resource limitations could not be treaed by the indian system. In modern societies, the formal authority system is necessary to achieve any social objectives.第 28 题 Which of the following statements about the European soldiers is correct?

All of us rely on what we see．We say to ourselves，“I know，was there；I saw it hap-pen．”And that seems to settle the matter．Or does it?Can we really trust the evidence of oureyes?Take competitive sports．Fans who see the same game will not agree with each other and will the disagree with the referee(裁判)．“He was out of bounds when he caught the pass，”says one fan．Says another，“You are crazy．I saw it with my own eyes．He was five feet in bounds．You must be blind．”The referee rules that the receiver did step out of bounds．But thousands of fans are still not convinced--because they were there!
