怎样理解坚持真理与修正错误的关系?

答案

参考答案:

坚持真理不容易、修正错误更难。修正错误是坚持真理的特殊表现。科学活动中的错误可能来自两个方面:一是对正确事实进行抽象概括所犯的错误;二是由于观察的错误。使获得的事实本身不合客观实际。不论哪一种都是主观同客观的不一致,都要勇于修正。勇于修正错误,是坚持实事求是,不为名利所左右,老老实实的求实精神和科学态度的表现,是一切优秀科学工作者应具有的崇高品质。

It was the last day of the final examination in a large eastern university. On the steps of one building, a group of engineering students were talking about the exam that was going to begin in a few  36 . On their faces was confidence . This was their last exam — then on to 37 and jobs.
Some talked of jobs they already had; others talked of jobs they 38 get. With the certainty of four years of college, they felt ready and able to take 39 of the world.
The coming exam, they knew, would be a(n)  40 task. The professor had said they could bring  41 books or notes they wanted, requesting only that they did not 42 each other, during the test.
 43 they entered the classroom. The professor passed out the papers. And smiles 44 on the students’ faces as they noted(注意到) there were only five essay-type questions.
Three hours had passed 45 the professor began to collect the papers. The students no longer looked confident. On their faces was a frightened expression. Papers in hand, no one spoke as the professor faced the class.
He looked at the 46 faces before him, and then asked, “How many completed all five questions?” 47 a hand was raised.
“How many answered four?” Still no hands.
“Three? Two?” The students moved restlessly (不安地,慌张地)in their seats.
“One, then? Certainly somebody finished 48 .”But the class remained silent.
The professor put down the papers. “That is exactly what I 49 ,” he said. “I just want to impress upon you that,   50 you have completed four years of engineering, there are still many things about the   51 you don’t know. These questions you couldn’t answer are relatively(相对地,相当地)  52 in everyday practice. ” Then smiling, he added, “You will all  53 this course, but remember — even though you are now college graduates, your education has just  54 .”
The years have 55  the name of this professor, but not the lesson he taught.
