Ontological Revolution of Marx's Dialectics

As a special theoretical thinking,dialectics has its ontological promise.It comes from the seeking and criticizing of its promise noumenon,so that dialectics always gets entangled in ontology.Criticism is the nature of dialectics,but its nature of criticism is the reflection and criticism of internal contradiction of its promise noumenon,not a simple negation of things.Through the reflection and criticism,Marx has achieved an ontological revolution of practical critical dialectics which based its fundamentals on the mode of people's living.
