‘성경(誠敬)’을 통해서 본 정호의 수양공부론

Abstract

Sincerity and Piety are usually combined together to define justice as the word Justice of Sincerity and Piety. However, the concepts of Sincerity and Piety imply the meaning of self-discipline study theory respectively. It was Cheng Hao who suggested the study of self-discipline focused on Sincerity and Piety, which was distinguished from Cheong Yi’s theory. He thoughts that Sincerity meant the life that consisted of reliable behaviors, which would extend its meaning up to the ideal level. Piety is not only a clear self-discipline method that plays a behavior standard to everyday life but also considered as same as Sincerity. The concept of Sincerity and Piety is essential in grasping Cheng Hao’s idea system while exposing its attribute as a study of the existence root. This study is developed in the way to expose the attribute of the study theory suggested by Cheng Hao through a convergent consideration on the Justice of Sincerity and Piety in which they are integrated into Justice in order to explain their meaning shown by him, which will be a meaningful work to understand Cheng Hao’s idea in overall.
