本文旨在「系統」與「他者」兩條思路的交織之下，重訪朱熹思想。朱 熹是一大體系的建造者，就建構體系是思想家負責任的表現而言，朱熹對於後現代 思潮應該有所啟示。男一方面， 他者」是人生與存在的重要向度，在後現代思潮 中特別加以強調，以替代近代以來過度膨脹的主體，與「他者」的關係有助於我們 更深入理解朱熹。 本文所用「感謝」一詞， 可以視為表謝意的複合動詞，也可以拆為二字: 「感」者，有所受於他者， 謝」者，對所受於他者表示感激。人之所以能成長， 乃至構成圓融的人格或體系， 所受之他者甚眾。對他者有正面的接受， 固然喜悅; 能對所受有所感，且能還報以感激之情，則更增益喜悅。知道感恩者， 內心常存喜 悅， 而且是雙重的喜悅。 就某種意義言，本文也可以說是在探問: 對他者的感與謝， 是否也是朱熹建構 其哲學體系的源頭活水。有感於他者，並向他者致謝，既是心靈雙重喜悅的來源， 則人格與思想成熟如朱熹者，或也應有所體會，使此一雙重喜悅成為其道德實踐與 思想、創造的來源。本文分別從倫理關係中的他者、義理中的他者(含心性論、方法 論、與終極他者) ，和成德之方與我他圓融等方面分別對朱熹思想加以評析。 This paper takes the contrasting dialectics between “ System" and “ the other" as a guideline for the reinterpretation of Chu Hsi's philosophy. Generally, Chu Hsi is recognized as a great system builder in the history of Chinese philosophy. We look on the effort of constructing a coherent system as a sign of a responsible thinker. In this respect Chu Hsi must have something to say for the postmodern philosophy character- ized by deconstruction and anti-system. On the other hand, “ the other", essential to human existence and reality as a whole, is cherished by postmodern philosophy against the domination of modern subjectivity. The concept of “the other" could offer us a new perspective for 悶-reading Chu-Hsi 's philosophy produced in the pre-modern era. In some sense, the problematic of this paper is to ask whether “ generosity of the other" and “ grati tude to the other" were also an inspiring source for Chu Hsi's philosophy We will proceed to answer this question and to re-evaluate Chu Hsi 's philosophy first from “ the other" in ethical relationship, then "the other" in Chu Hsi's philosophical system, such as his theory of human mind/heart, his methodological discussion of “ investigation of things" and finally the Ultimate Other in his system. We will also try to analyze the role of the other in his theory of self-cultivation.
