Abstract: It is the ideologist's self-consciousness to contemplate the social life from the perspective of general necessity.Within the ideological system of Cheng-zhu's Philosophy of TianLi,the process in which people reach the principle of TianLi depends on the investigation of things or Gewu.It is impossible that the subject should directly understand the principle.However,it is not the reliance on the absoluteness of the principle but the externalization of the moral integrity through the understanding of the behavioral subject that determines the internalization of the external ethics into the individual moral integrity.Lu Jiuyuan's theory,which attached equal importance to both mind and principle,couldn't essentially solve the inner paradox of the Theory of TianLi.It was Wang Yangming who was living in Ming Dynasty that highlighted and developed the individual subjectivity via two aspects of reality and gongfu through the Theory of Noting existing beyond the mind.
