In late 1960's, electricity had just been brought into a village in Nigeria where a friend and his family were living. Each family got a single light in its hut: a real sign of progress. The trouble was that at night, though they had nothing to read and many of them did not know how to read, the families would sit in their huts in awe of this wonderful symbol of technology.
The light-bulb watching began to replace the customary nighttime gatherings by the tribal fire, where the tribal storytellers, the elders, would pass along the history of the tribe. The tribe was losing its history in the light of a few electric bulbs.
This story helps to illustrate the difference between scientific management and tribal leadership. Every family, every college, every corporation, every institution needs tribal storytellers. The penalty for failing to listen is to lose one’s history, one’s historical context, one’s binding values. Like the Nigerian tribe, without the continuity brought by custom, any group of people will begin to forget who they are. 【題組】47 According to the passage, what did the light-bulb symbolize in Nigeria in late 1960's?
(A)leadership (B)history (C)tribal life (D)progress
