When I was a law professor, a student reported that I made an error in grading his exam by giving him too many points. He was         and after thanking him for his honesty, I changed the          in my records. His beaming (欢笑的) face turned to         “You’re lowering my grade?” he said angrily. “I would never have come in          ……”
He didn’t finish the          but it was obvious that his display of honesty was false. He thought he’d have it all—praise and the          grade.
Several colleagues thought I should have let the higher grade stand        all I’d accomplished was to discourage him from being         in the future. And every time I tell this         , some people agree with this remark.
But I can’t see how I could give good          for worsening my mistake in grading by undermining (损害) the honesty of all my grades by failing to          an error. The grade itself would be a dishonest reflection of his          and it would have been         to other students. How could I possibly give a          a gift of an unearned grade?
I know voluntarily reporting an error in one’s favor is         , but, like          extra change, it’s the         thing to do. People with real honesty, hate to give up benefits as mush as anyone else. The difference is that for them a good conscience and reputation is reward enough to give reason for the cost of doing the right thing.
Perhaps         the student’s grade did discourage him from being honest in the future, but bribing (贿赂) him to be honest so that he does the right thing when it’s cost-free would have         him even more. The duty to be honest is         right and wrong, not risks and rewards.
