Wang Chuan-Shan's “Intuition Theory” is an important part of his overall philosophy. The theory of intuition includes a relationship between subject and object and includes the categories of “neng suo” and “shen xing”. This article examines the source, content, theory and practice of the notion of “neng suo”. It also examines the internal and external principles of “fa fu”, “si wei” and “ji wu”. It explains the theory's form, spirit and material factors and their harmony and mutual “xiang zhi”. This article investigates intuition and contrasts intuition with feeling and emotion. The mind's spirit finds its subject of contemplation in inference from intuition and judgment, thus achieving a rational moral intuition. This article then focuses on how one achieves knowledge. What is epistemological method? The answer lies in study and speculation, then how to put them into practice. Form this perspective of study and contemplation, we make a critique of the “chun gu zhe shi” and “min duan zhe shi” tendencies.
