一天,有个学生突然问我:“老师,《劝学》里说‘木直中绳,鞣以为轮,其曲中规’,这不是有意将直材鞣成弯材吗?这怎么理解?”是的,生活中,人们一般都是将弯材育成直材,更多的是弯材弯用,而很少有将直材特意鞣成弯材的。我肯定了学生有疑必问是对的,并告诉学生说,荀子之所以引以为据,意在说明“学”的巨大功用。 One day, a student suddenly asked me: “The teacher, ”Encouragement,“ said that ”Mukaki was in the ropes, and he thought that the wheel was in tune.“ Isn’t it intended to bend the straight material into a curved material? How do you understand this? ”Yes, in life, people generally develop bentwood into straight materials, and more bent materials are used for bending, and few straight materials have been deliberately bent into curved materials." I affirmed that the student must be asked if he was skeptical. He told the students that Xuanzi used the evidence to explain the great function of “learning”.
