在儒學發展史上，北宋程顥、程頤兄弟與南宋朱熹（合稱 “程朱”）之所以極力凸顯 “入德之門” 的重要性，絕非單純的經典考據選擇，而是關乎儒學生死存亡的 “道術重構”。其本質是回應兩大核心挑戰：在思想層面，重塑儒家義理的形上高度，與佛、道兩教爭奪中國人的精神主導權；在教育層面，重建由 “初學” 通往 “聖賢” 的道德階梯，扭轉漢唐以來章句訓讀脫離道德實踐的學風。 In the history of Confucianism, the reason why the Northern Song brothers Cheng Hao and Cheng Yi together with the Southern Song’s Zhu Xi (collectively known as the “Cheng-Zhu” school) so vigorously highlighted the importance of the “Gateway to the Virtue Realm of Sagehood ” was by no means a simple choice of classical exegesis; rather, it concerned a “reconstruction of the Way and its arts” that would determine the very survival of Confucianism. Its essence lay in responding to two core challenges: at the intellectual level, to...

As a core theoretical proposition in the practical philosophy of Cheng-Zhu Neo-Confucianism, “Gateway to the Virtue Realm of sagehood ” defines the fundamental starting point of Confucian moral cultivation. The Cheng Brothers regard The Great Learning as the essential entry for novice learners to pursue virtue. Inheriting this doctrinal judgment, Zhu Xi reconstructs the framework of the “Three Fundamental Principles and Eight Practical Articles” articulated in The Great Learning and formulates a hierarchical and progressive system of virtuous cultivation. This cultivation trajectory initiates from the investigation of things and extension of knowledge, advances through the sincerity of volition, rectification of the mind, self-cultivation, and familial regulation, and ultimately culminates in state governance and world pacification. Centered on the sagehood ideal and grounded in the canonical exegeses of The Great Learning by the ...

“入德之門” 是程朱理學工夫論的核心命題，標定了儒家學者道德修養進程的道德起點。二程將《大學》定性為 “初學入德之門”，朱熹承續這一學術判定，通過重構《大學》的 “三綱領八條目”，搭建起由格物致知起始、經由誠意正心與修身齊家、終達治國平天下的完整進德路徑。本文以學為聖賢的理想目標為導向，以程朱《大學》詮釋的原典為核心依據，結合相關學術研究成果，逐層解析 “入德之門” 的本體內涵、工夫方法及理論意義，闡明其貫通內聖外王的次第邏輯，揭示儒家下學而上達、由初學入門終至聖賢境界的道德修養進程。  The “Gateway to the Virtue Realm of Sagehood ” is a core proposition in the theory of self-cultivation (gongfu) of Cheng-Zhu Neo-Confucianism, marking the virtue starting point of the Confucian process of moral cultivation. The Cheng brothers defined the Confucian Classic The Great Learning as “the gate for beginners to enter the Virtue Realm of Sagehood,” and Zhu Xi inherited this doctrinal judgment. By reconstructin...
