《天下》是中国历史上最早的一篇思想或学术史专论。从古之道术到百家之学,其学术立场是进退诸子、宗本老庄、遮拨名辩、复归无名。作为殿后之作,文辞精美,思想宏阔,开放包容,涵盖面广,在《庄子》中占有特殊地位。从中依稀可辨庄子与春秋战国之际诸子思想之关联。 “World” is the earliest monograph in Chinese history, ideological or academic history. From ancient Taoism to one hundred schools of learning, its academic position is to advance and retreat philosophers, Zongben Lao Zhuang, cover up defamation, return to the unknown. As a dynasty’s masterpiece, the essay is exquisitely written, wide-minded, open and inclusive, covering a wide range and occupying a special place in Zhuangzi. From which we can discern the connection between Zhuangzi and philosophers of the ages in the Spring and Autumn Period and the Warring States period.
