Through a literature review of the works by Li Zehou since 1970s, the writer claims that besides practical discourse Li Zehou also puts stress on reshaping of human nature, creation of initial intuition and formation of cultural psychology. And on this basis, Li Zehou proposes two types of contrastive ontology, i.e., sentiment and instrument. These theoretical assumptions constitute his subjective discourse that is not meant to derail from the Chinese principles of practical aesthetics. In effect, Li Zehou makes use of the dialectics by Kant and Marxist practices.
