本文嘗試各方面論述「《周易》用世思想之研究」，及其不易現蹤之各種獨特用世跡象，勾勒其哲學智慧與關鍵知識的價值，企圖揭啟「用世」渠道中的各種微妙人性，若得善用於日常之中，亦能實用防患於未然，祥和自在。文中也并合孔聖所言之「聖人之道」，為本文之論述核心概念，進而探討《周易》之「用世」的整全民生思想，並肯定在「用世」的過程中引述動微之「幾」者，確為《周易》用世之不可或缺之精神指標。 本文亦循序探討在《周易》用世思想之內涵：貞之于太極，貞之于憂患，貞之于聖道，三者之中依序論述《周易》之用世思想是有跡可循、天人合德的，並依此人類探索未來的需求意識，再論證「知幾」的智慧，藉以參研因應民生，祈與作易者用世之心不謀而合，在此筆者將盡力提供應有的把握。 《周易》用世思想之變化最為實惠並耐人尋味，伴隨著宇宙時空背景間，在你我他，以及各類芸芸眾生之中，氤氳而生已然由來已久。寂然不動卻能萬物不遺，道濟天下，故筆者以廣納百川之心，不論門戶，客觀的探賾索引，綜合《周易》用世廣被眾生珍貴之處，謹就「用世」思想之實踐功夫，分析其效益知識價值，略分為三個重要介面，嘗以稱名為：一、用世在於明理，二、用世在於知幾，三、用世在於應變，逐步進行研究，此三者可分可合，分則顯而易懂，合則間隙難定，撲朔迷離，各有特色。文中將依其出現現象順序，假以階段式的特質，提出參研之論證說明。再回顧用世內涵與實踐之因果關係；同時也在知幾的實務面向上做未雨綢繆之呼應。筆者衷心祈盼藉此喚起學者，對《周易》用世煥然一新的觀念與興趣，日後進行更多的用世詮釋活動而廣被眾生。 This study attempted to clarify the practical applications and the inconspicuous phenomena of Zhouyi, also to reveal the humanity that was hidden in the applications.
