鄭齊斗為韓國朝鮮朝最重要的陽明學者,在當時以朱學為正統官學的環境中,捍衛學術思想的獨立,不受朱學氛圍的影響,始終堅持站在陽明學的角度,替其發聲。除此之外,鄭齊斗其實也是相當注重經世致用的,並非單純的哲學家而已,他的經世思想,即源於其之陽明學立場。本文的研究,即是探究鄭齊斗如何以「心即理」來建構他的經世之學,主要分為四節,第一節的文獻回顧,指出鄭齊斗經世之學的重要性,第二節則是從「心即理」的角度,解析鄭齊斗如何繼承陽明學,也是他經世之學的出發點;第三節則重在以理禮雙彰的方式,從「心即理」到「理即禮」,描繪鄭齊斗經世之學的內涵;第四節則是對全文作出總結。藉由這些論誰,冀能增進學界對於鄭齊斗的瞭解。
Chong Che-du 鄭齊斗is the most important of Korea's Yangmingist 陽明學thinkers . He espoused the school's ideas and fought for its integrity at a time when Zhu Xi 's 朱熹doctrines were regarded as orthodox and dominated the intellectual climate. Though primarily a philosopher, Chong is also concerned with statecraft, a preoccupation whose roots also lie in Yangmingism. In four parts , this essay explores how Chong's concept of "mind as principle 心即理" forms the foundation of his philosophy of statecraft, shedding new light on this figure . Part one provides a literature review of the significance of Chong's philosophy of statecraft; part two analyzes Chong's Yangmingist inheritance, which is also the starting point of his own philosophy of statecraft; part three shows the correspondence between principle 理and rite 禮, describing two components from which Chong constructs his philosophy of statecraft: "mind as principle" and "principle as rite"; part four draws some conclusions.
