经权思想的逻辑进路——以汉儒、宋儒和明儒为中心的考察

经权思想是儒家哲学的重要内容。自从孔子将经权提升为哲学方法论范畴之后，汉儒、宋儒和明儒分别阐发了“反经合道”说、“权便是经”说和“经是已定之权，权是未定之经”说或“经乃有定之权，权乃无定之经”说。这三种经权观恰好构成否定之否定的辩证发展过程。

The Logical Approaches to the Constancy-expediency Thought——Based on the Research of the Confucianism of Han Dynasty, Song Dynasty and Ming Dynasty

The constancy-expediency thought is an important part of the Confucian philosophy. Since Confucius upgraded the constancy-expediency thought into the philosophical category, the scholars of Confucianism of Han dy- nasty, Song dynasty and Ming dynasty respectively expounded it into the thought that＂ though it is against the con- sistent practice, it is still on moral principles＂ , the thought that ＂ the expediency is the constancy＂ , and the thought that＂ the constancy is the fixed expediency, while the expediency is the flexible constancy＂ The three thoughts exactly constitute the dialectical development process of the law of negation of the negation. Sorting out the internal logic of the process is undoubtedly of great significance for deepening the constancy-expediency thought of Confucianism.
