??In many businesses, computers have largely replaced paperwork, because they are fast, effective（高效的）, and do not make mistakes．As one banker said, “Unlike humans, computers never have a bad day.” And they are honest.

??Many banks advertise that their work is “untouched by human hands” and therefore safe from human attack. Computers have no reason to steal money. But they also have no sense, and the growing number of computer crimes (犯罪) shows they can be used to steal.

??Computer criminals don’t use guns. And even if they are caught, it is hard to punish them because there are no witness (证人) and often no proof (证据). A computer cannot remember who used it and simply does what it is told. The head teller(出纳) at a New York City bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this because he moved the money from someone else’s account (帐目)．This man was caught only because he was a gambler (赌徒). When the police broke up a gambling group, his name was in the records.

??Some workers use the computer’s power to get revenge（报复）on bosses they consider unfair. Recently, a large company fired its computer assistant (助手) for reasons that were connected with her personal rather than her professional（职业的）life. She was given thirty days’ notice. In those thirty days, she got rid of all the company’s computerized records.

??Most computer criminals have been workers in low position. Now police wonder if this is “the tip of the iceberg（冰山）”. As one of the officials says, “I have a feeling that there are more crimes out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing — the ones who really know how a computer works.”

I came to live here where I am now between Wounded Knee Greek and Grass Greek. Others came too, and we made these little grey houses of logs that you see, and they are square. It is a bad way to live, for there can be no power in a square.

You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round. In the old days when we were a strong and happy people, all our power came to us from the respectful circle of the nation, and so long as the circle was unbroken, the people were getting rich. The flowering tree was the living center of the circle, and the circle of the four quarters nursed it. The east gave peace and light, the south gave warmth, the west gave rain, and the north with its cold and strong wind gave strength and continuous power. This knowledge came to us from the outer world with our brief. Everything the Power of the World does is done in a circle. They sky is round, and I have heard that the earth is round like a ball, and so are all the stars. Birds make their nests in circle, for theirs are the same as ours. The sun comes forth and goes down again in a circle. The moon does the same, and both are round. Even the seasons from a great circle in their changing, and always come back again to where they were. The life of a man is a circle from childhood to childhood, and so it is in everything where power moves. Our places were like the nests of birds, and these were always set in a circle, the nation’s a nest of many nests, where the Great Spirit meant for us to nurse our children.

But the Wasichus (Indian word for “white people”) have put us in these square boxes. Our power is gone and we are dying, for the power is not in us any more. You can look at our boys and see how it is with us. Where we were living by the power of the circle in the way we should boys were men at twelve or thirteen years of age. But now it takes them very much longer to be bull-grown.
