What is “l(fā)ogic”？ Do you know？

什么是“邏輯”？你知道嗎？

One day， Einstein asked the students in class， “There are two workers who repair the old chimney. When they climb out of the chimney， one is very clean and the other is covered with coal ash. Who will take a bath？”

一天，愛(ài)因斯坦在課堂上問(wèn)學(xué)生：“有兩個(gè)修理舊煙囪的工人，當(dāng)他們爬出煙囪時(shí)，一個(gè)人身上非常干凈，另一個(gè)人沾了一身煤灰。誰(shuí)會(huì)洗澡？”

A student said， “Of course， the worker with a face and body full of coal ash went to take a bath！”

一個(gè)學(xué)生說(shuō)：“當(dāng)然是那個(gè)滿(mǎn)臉滿(mǎn)身沾上了煤灰的工人將會(huì)去洗澡了！”

Einstein asked， “Really？ Please note that the clean worker saw another one with a face full of coal ash. He thought it was dirty to climb out of the chimney. The other saw that the other was clean， so he didn't think so. Now I'll ask you again who will take a bath？”

愛(ài)因斯坦問(wèn)道：“真的嗎？請(qǐng)注意，那個(gè)身上干凈的工人看到另一個(gè)工人滿(mǎn)身煤灰，他認(rèn)為，從煙囪里爬出來(lái)是臟的。另一個(gè)工人看到對(duì)方身上是干凈的，所以他就不這么認(rèn)為了?，F(xiàn)在我再問(wèn)你們，誰(shuí)將會(huì)洗澡？”

Another student was very excited to find the answer， “0h！ I know！ When the clean worker saw the dirty worker， he thought he must be very dirty. But when the dirty worker saw the clean worker， he thought he was not dirty！ So the clean worker must have gone to take a bath.”

另一個(gè)學(xué)生找到了答案，很興奮地說(shuō)道：“哦！我知道！當(dāng)身上干凈的工人看到身上臟的工人時(shí)，他認(rèn)為自己身上一定也很臟。但是，當(dāng)身上臟的工人看到身上干凈的工人時(shí)，他認(rèn)為自己身上也不臟！所以，身上干凈的那個(gè)工人一定會(huì)去洗澡?！?/p>

Einstein looked at the other students. All the students seemed

to agree with that answer. Einstein said slowly， “I'm sorry to tell you that the answer is wrong. If two people climb out of the old chimney at the same time， how can one be clean and the other dirty？ This is called ‘logic’.”

愛(ài)因斯坦看著其他學(xué)生。似乎所有的學(xué)生都同意這個(gè)答案。愛(ài)因斯坦慢慢說(shuō)道：“我很抱歉地告訴你們，這個(gè)答案是錯(cuò)的。如果兩個(gè)人同時(shí)從舊煙囪里爬出來(lái)，怎么可能一個(gè)人身上干凈而另一個(gè)人身上臟呢？這就叫作‘邏輯’?！?/p>
