Abstract: In the context of post-modernism,“deconstructing ontology” has become a powerful ideological trend of “philosophy”,but ontology is precisely the core of “philosophy”.The necessity of ontology lies in that all human ideas about the being of all beings must be an orderly hierarchical whole,and it must have a spire,which is the so-called “noumenon” of ontology;otherwise human ideas will not be an orderly system.Therefore,the attitude of Life Confucianism is that we must deconstruct the old ontology,but at the same time,we must construct a new ontology.For this reason,it must be traced back to Being or Life of the “pre-noumenon” and the “pre-being”,that is:the theory of Life or Life as Being lays the foundation for ontology,and ontology lays the foundation for sub-metaphysics(epistemology and ethics).So Life Confucianism constructs a universal “Variable Ontology”,and then constructs a “Transcendent Ontology” that especially points to modernity.

Key words: Life Confucianism, noumenon, transcendence
