Abstract
Philosophy of law is philosophy about law. common critical ontology examines the structure of the world which is hierarchical and is composed of four fundamental levels; the anorganic being, the organic being, the psychical being and the spiritual being, where we meet the personal, objective and the objectified spirit. the new critical ontology is science in the strictest sense of the word and consequently goes out from the total experience. critical legal ontology examines the essence of law and states where the law belongs; in the ideal world or the real world, and states its place in these worlds. it appears that the so far unsolvable fundamental question, i.e., the problems of law and power, and law and revolution are easily and "cum ratione" sufficient to be solved on the basis of this new science.
