曾经听到一位老师在讲授《论语》时,把“吾日三省吾身”的“三省”解释为反省三件事,把“三思而后行”的“三思”解释为思考三次,这其实是不确切的。在汉语里,“三”有实数和虚数两种意义:实数指确定的自然数,也就是二加一所得之数;虚数则泛指多数或者多次。清代著名学者汪中写有《释三九》一文,从古书中举了很多例子来论证此事,早已为人们所熟知。 When I heard a teacher telling the Analects of Confucius, I interpreted the “three provinces” in “My Wushu in Wuri, Japan and Japan” as three introspectives and explained “three thoughts” as “thinking twice before”, which is actually Inaccurate. In Chinese, “three” has two kinds of meanings, real and imaginary: real refers to the definite natural number, that is, the sum of two plus one; the imaginary refers to the majority or multiple. Wang Zhong, a well-known scholar in the Qing Dynasty, wrote an article entitled “Three Thirty-nine Years of Release,” and many examples have been given from the ancient books to prove the matter, which has long been known to people.
