张介宾医易思想探析

Exploration and analysis on Zhang Jie-bin＇ s medlcine-changing thinking

张介宾的《医易义》是一篇医学哲学的代表作。文中提出“医易同原”、“医易相通”两个命题，前者是从太极本原层面说的，后者是从阴阳变化道理层面说的。关于“太极”，张介宾有时说是“理”，有时说是“气”，通过研究发现，张介宾是主张理气合一、以气为主的。关于“阴阳”，实际上包括四象五行八卦变化之理，是天道和人道、医学和哲学会通的焦点。张介宾不仅以易理来解说医理，而且强调学习中医必须学习《周易》，说明中医学与哲学的密切关系。

Zhang Jie-bin＇ s Yi yi yi （Implication of Medicine-Changing） is his representative work on medical philosophy, in which two topics were mentioned, the ＂Iso-source of medicine and changing＂ and ＂communication between medicine and changing＂. The former one was based on the source of TaXi, while the latter, on the rules of changes of yin and yang. In terms of Taifi, Zhang maintained that it was a ＂principle＂ or ＂qi＂. Through our research, it is found that Zhang held that principle and qi were combined as a unity, with qi as its main aspect. In terms of yin and yang, it actually include the changing principles of four quadrants, five phases and eight trigrams, heing the focus of communication between the law of universe and law of humankind, and medicine and philosophy. Zhang not only interpreted medical principles, through changing principles, hut also emphasized that, to learn medicine, one must learn the Zhou yi （ Book of Changes of Zhou ） , indicating the close relationship between medicine and philosophy.
