清华战国竹简八卦人体图“坎离”探秘

Exploration on ‘Kan and Li' of image of eight diagrams and human body on bamboo slips of Tsinghua warring states period

清华简《筮法》中坎卦和离卦与后天八卦颠倒,以坎为火,离为水,图的中央是一个人体,认为其应与医学相关。通过对全书中"坎、离"的整理归纳,同时结合上下文,并与《说卦传》的相关内容进行比较,从医易体用关系转化和变易思维影响两个方面对"八卦人体图"的坎离互置进行了分析,认为坎离互置体现了中医学从重视形体向重视功用的转变,是医易理论之先声,同时也可能与卦象的周期变易规律有关。

Kan and Li in Shifa chapter of Tsinghua bamboo slips were reversed compared with postnatal eight diagrams. Trigram Kan symbolizes fire while trigram Li represents water. A human body can be seen in the center of the image, which is thought to be related with medicine. The present study has sorted out and summed up Kan and Li throughout the whole book, compared them with the related content in Shuoguazhuan, and analyzed the exchange of Kan and Li in the image of the eight diagrams and human body from the aspects of essence-function transformation of medicine and Yi, and the impact of thinking on changing. The results show that the exchange of Kan and Li reflects the transformation of traditional Chinese medicine's attention from physique to function, which has heralded medicine-Yi theory and is probably connected with the periodic variation law of images of the trigrams.
