For Critical Ontology, metaphysics, indeed all philosophy, should be based on our empirical experience. So it approves the Kantian critical epistemology of founding knowledge on experience. By "critical" it means "based on the analysis of the empirical." But it does not endorse the Kantian agnosticism of metaphysics. Critical Ontology argues that metaphysics is possible and productive. Metaphysics is possible due to the human intellect's inner dynamism to go "beyond." Our intellect makes metaphysical postulations based on the analysis of the empirical.

Critical Ontology defines ontology as search for being-principles. Every entity has a constitutive principle, which the new method conveniently calls "being-principle." To understand an entity ultimately means to know its being-principle.

Critical Ontology does not want us to remain at the metaphysical level. With the knowledge of being-principle, it wants us to return to the empirical for relevant action.

One can use Critical Ontology to analyze any philosophical problem, indeed any issue we want to understand. The method of Critical Ontology consists of four steps: Experience, Analysis, Postulation, and Application.
